Dr. Reed testified that his opinion regarding plaintiffs ability to work did not change. (Tr. 90).
Plaintiffs attorney re-examined plaintiff, who testified that he had reported suicidal thoughts to Dr. Gavirneni in September 2009, but Dr. Gavirneni did not include this in her treatment notes. (Id.). Plaintiff stated that he had contacted the clinic and attempted to get this clarified. (Tr. 91).

Plaintiffs speech was normal, and there was no evidence of loose or bizarre thought associations. (Id.). Plaintiff presented with psychotic symptoms, including paranoid thinking, and possible hallucinations. (Id.). The quality of plaintiffs thinking, and mental control were intact. (Id.). Plaintiffs memory functions appeared problematic. (Id.). Plaintiffs daily activities appeared to be restricted by mood symptoms and psychotic symptoms. (Id.). Plaintiff demonstrated no significant difficulties in understanding or following simple instructions, or managing his own funds. (Id.). Plaintiff had significant problems tolerating normal external stress and vocational pressures due to his symptoms. (Id.). Dr. Dempsey diagnosed plaintiff with bipolar I disorder, mixed, severe with psychotic features; schizoid personality traits; and a GAF score of 40. (Tr. 534). Dr. Dempsey expressed the opinion that plaintiff was disabled and was medically eligible for public assistance. (Tr. 535).
Plaintiff saw Dr. Lipsitz on July 27, 2009, for a psychological consultation. (Tr. 540-42). Plaintiff reported mood swings, inability to sleep, inability to focus, increased anger, depression, fatigue, lack of motivation, and occasional suicidal thoughts. (Tr. 540). Upon mental status examination, plaintiff was in no acute distress, was oriented, and demonstrated no evidence of any active psychotic functioning. (Tr. 542). Plaintiffs affect was flat and his mood was depressed. (Id.). Plaintiff reported recurrent suicidal ideations, but no active plans or intent. (Id.). Plaintiff demonstrated no memory problems, and his concentration was good. (Id.). Plaintiffs insight and judgment were somewhat poor. (Id.). Plaintiffs thought processes were primarily preoccupied with his mood swings and his inability to function within society. (Id.). Dr. Lipsitz diagnosed plaintiff with bipolar disorder, and a GAF score of 50. (Id.). Dr. Lipsitz found that plaintiff had moderate restrictions in activities of daily living, moderate difficulties in maintaining social functioning, and mild deficiencies of concentration, persistence, or pace. (Tr. 543). Dr. Lipsitz expressed the opinion that plaintiff had a marked restriction in his ability to respond appropriately to usual work situations and changes in a routine work setting, and moderate restrictions in his ability to interact appropriately with the public, interact appropriately with supervisors, and interact appropriately with co-workers. (Tr. 545).
Plaintiff saw Dr. Gavirneni on September 28, 2009, at which time Dr. Gavirneni stated that plaintiff was doing well, and that his mood was stable. (Tr. 547). Dr. Gavirneni noted that plaintiff reported experiencing mood swings the previous month and that he was instructed to call if this occurred again. (Id.). Dr. Gavirneni stated that plaintiff was tolerating his medications well. (Id.). Dr. Gavirneni *938found that plaintiffs mood was good, his affect was euthymic, and his insight and judgment were fair. (Id.).
The ALJ’s Determination
The ALJ made the following findings:
The claimant met the special earnings requirements of the Act as of July 6, 2007, the alleged onset of disability, and continues to meet them through the date of this decision.
The claimant has not engaged in substantial gainful activity since July 6, 2007. He worked about one week at another job in the third quarter of 2007, but it did not constitute substantial gainful activity in terms of duration of employment or amounts of average monthly earnings according to the earnings guidelines of 20 CFR 404.1574 and 416.974.
The medical evidence establishes that the claimant has obesity, and asthma, hypertension, hypothyroidism, sinusitis, and bipolar disorder controlled by medication, but no impairment or combination of impairments that meets or equals in severity the requirements of any impairment listed in Appendix 1, Subpart P, Regulations No. 4.
The claimant’s allegation and that of his mother of impairments, either singly or in combination, producing symptoms and limitations of sufficient severity to prevent the performance of any sustained work activity by the claimant are not credible, for the reasons set out in the body of this decision.
The claimant has the residual functional capacity to perform the physical exertional and nonexertional requirements of work except probably for lifting or carrying more than 10 pounds frequently or more than 20 pounds occasionally; having concentrated or excessive exposure to dust, fumes, chemicals, temperature extremes, high humidity or dampness, and other typical allergens, pollutants, and atmospheric irritants; doing more than simple, repetitive tasks; or having more than occasional contact with coworkers, supervisors or the general public (20 CFR 404.1545 and 416.945).
The claimant’s past relevant work as a production assembler did not require the performance of work-related activities precluded by the limitations described in Finding No. 5 (20 CFR 404.1565 and 416.965). The impairments established in this case do not prevent the claimant from performing this past relevant work, according to vocational expert opinion.
The claimant was not under a “disability,” as defined in the Social Security Act, at any time through the date of this decision (20 CFR 404.1520(f) and 416.920(f)).
(Tr. 21).
The ALJ’s final decision reads as follows:
It is the decision of the Administrative Law Judge that, based on the applications filed on February 2, 2008, the claimant is not entitled to a period of disability or to disability insurance benefits under Sections 216(1) and 223, respectively, of the Social Security Act.
(Tr. 22).
Discussion
A. Standard of Review
Judicial review of a decision to deny Social Security benefits is limited and deferential to the agency. See Ostronski v. Chater, 94 F.3d 413, 416 (8th Cir.1996). The decision of the SSA will be affirmed if substantial evidence in the record as a whole supports it. See Roberts v. Apfel, 222 F.3d 466, 468 (8th Cir.2000). Substantial evidence is less than a preponderance, but enough that a reasonable mind might accept it as adequate to support a conclu*939sion. See Kelley v. Callahan, 133 F.3d 583, 587 (8th Cir.1998). If, after review, it is possible to draw two inconsistent positions from the evidence and one of those positions represents the Commissioner’s findings, the denial of benefits must be upheld. See Robinson v. Sullivan, 956 F.2d 836, 838 (8th Cir.1992). The reviewing court, however, must consider both evidence that supports and evidence that detracts from the Commissioner’s decision. See Johnson v. Chater, 87 F.3d 1015, 1017 (8th Cir.1996) (citing Woolf v. Shalala, 3 F.3d 1210, 1213 (8th Cir.1998)). “[T]he court must also take into consideration the weight of the evidence in the record and apply a balancing test to evidence which is contrary.” Burress v. Apfel, 141 F.3d 875, 878 (8th Cir.1998). The analysis required has been described as a “searching inquiry.” Id.
B. The Determination of Disability
The Social Security Act defines disability as the “inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or has lasted or can be expected to last for a continuous period of not less than 12 months.” 42 U.S.C. § 416(i)(l)(a); 42 U.S.C. § 423(d)(1)(a). The claimant has the burden of proving that s/he has a disabling impairment. See Ingram v. Chater, 107 F.3d 598, 601 (8th Cir.1997).
The SSA Commissioner has established a five-step process for determining whether a person is disabled. See 20 C.F.R. §§ 404.1520, 416.920; Bowen v. Yuckert, 482 U.S. 137, 141-42, 107 S.Ct. 2287, 2291, 96 L.Ed.2d 119 (1987); Fines v. Apfel, 149 F.3d 893, 894-895 (8th Cir.1998). First, it is determined whether the claimant is currently engaged in “substantial gainful employment.” If the claimant is, disability benefits must be denied. See 20 C.F.R. §§ 404.1520, 416.920(b). Step two requires a determination of whether the claimant suffers from a medically severe impairment or combination of impairments. See 20 C.F.R §§ 404.1520(c), 416.920(c). To qualify as severe, the impairment must significantly limit the claimant’s mental or physical ability to do “basic work activities.” Id. Age, education and work experience of a claimant are not considered in making the “severity” determination. See id.
If the impairment is severe, the next issue is whether the impairment is equivalent to one of the listed impairments that the Commissioner accepts as sufficiently severe to preclude substantial gainful employment. See 20 C.F.R. §§ 404.1520(d), 416.920(d). This listing is found in Appendix One to 20 C.F.R. 404. 20 C.F.R. pt. 404, subpt. P, App. 1. If the impairment meets or equals one of the listed impairments, the claimant is conclusively presumed to be impaired. See 20 C.F.R. §§ 404.1520(d), 416.920(d). If it does not, however, the evaluation proceeds to the next step which inquires into whether the impairment prevents the claimant from performing his or her past work. See 20 C.F.R. § 404.1520(e), 416.920(e). If the claimant is able to perform the previous work, in consideration of the claimant’s residual functional capacity (RFC) and the physical and mental demands of the past work, the claimant is not disabled. See id. If the claimant cannot perform his or her previous work, the final step involves a determination of whether the claimant is able to perform other work in the national economy taking into consideration the claimant’s residual functional capacity, age, education and work experience. See 20 C.F.R. §§ 404.1520(f), 416.920(f). The claimant is entitled to disability benefits only if s/he is not able to perform any other work. See id. Throughout this process, the burden remains upon the claim*940ant until s/he adequately demonstrates an inability to perform previous work, at which time the burden shifts to the Commissioner to demonstrate the claimant’s ability to perform other work. See Beckley v. Apfel, 152 F.3d 1056, 1059 (8th Cir. 1998).
The Commissioner has supplemented this five-step process for the evaluation of claimants with mental impairments. See 20 C.F.R. §§ 404.1520a(a), 416.920a(a). A special procedure must be followed at each level of administrative review. See id. Previously, a standard document entitled “Psychiatric Review Technique Form” (PRTF), which documented application of this special procedure, had to be completed at each level and a copy had to be attached to the ALJ’s decision, although this is no longer required. See 20 C.F.R. §§ 404.1520a(d), (d)(2), (e), 416.920a(d), (d)(2), (e); 65 F.R. 50746, 50758. Application of the special procedures required is now documented in the decision of the ALJ or Appeals Council. See 20 C.F.R. §§ 404.1520a(e), 416.920a(e).
The evaluation process for mental impairments is set forth in 20 C.F.R. §§ 404.1520a, 416.920a. The first step requires the Commissioner to “record the pertinent signs, symptoms, findings, functional limitations, and effects of treatment” in the ease record to assist in the determination of whether a mental impairment exists. See 20 C.F.R. §§ 404.1520a(b)(l), 416.920a(b)(l). If it is determined that a mental impairment exists, the Commissioner must indicate whether medical findings “especially relevant to the ability to work are present or absent.” 20 C.F.R. §§ 404.1520a(b)(2), 416.920a(b)(2). The Commissioner must then rate the degree of functional loss resulting from the impairments in four areas deemed essential to work: activities of daily living, social functioning, concentration, and persistence or pace. See 20 C.F.R. §§ 404.1520a(b)(3), 416.920a(b)(3). Functional loss is rated on a scale that ranges from no limitation to a level of severity which is incompatible with the ability to perform work-related activities. See id. Next, the Commissioner must determine the severity of the impairment based on those ratings. See 20 C.F.R. §§ 404.1520a(c), 416.920a(c). If the impairment is severe, the Commissioner must determine if it meets or equals a listed mental disorder. See 20 C.F.R. §§ 404.1520a(c)(2), 416.920a(c)(2). This is completed by comparing the presence of medical findings and the rating of functional loss against the paragraph A and B criteria of the Listing of the appropriate mental disorders. See id. If there is a severe impairment but the impairment does not meet or equal the listings, then the Commissioner must prepare a residual functional capacity assessment. See 20 C.F.R. §§ 404.1520a(c)(3), 416.920a(c)(3).
C. Plaintiff’s Claims
Plaintiff first argues that the ALJ erred in assessing plaintiffs mental impairments and in determining plaintiffs mental residual functional capacity. Plaintiff also argues that the ALJ erred in failing to consider the impact of plaintiffs obesity on his ability to work.
The ALJ made the following determination regarding plaintiffs RFC:
The claimant has the residual functional capacity to perform the physical exertional and nonexertional requirements of work except probably for lifting or carrying more than 10 pounds frequently or more than 20 pounds occasionally; having concentrated or excessive exposure to dust, fumes, chemicals, temperature extremes, high humidity or dampness, and other typical allergens, pollutants, and atmospheric irritants; doing more than simple, repetitive tasks; or having more than occasional contact with co*941workers, supervisors or the general public (20 CFR 404.1545 and 416.945).
(Tr. 21).
A disability claimant’s RFC is the most he or she can still do despite his or her limitations. 20 C.F.R. § 404.1545(a)(1). In McCoy v. Schweiker, 683 F.2d 1138 (8th Cir.1982) (en banc), the Eighth Circuit defined RFC as the ability to do the requisite work-related acts “day in and day out, in the sometimes competitive and stressful conditions in which real people work in the real world.” Id. at 1147. The ALJ’s determination of an individual’s RFC should be “based on all the evidence in the record, including ‘the medical records, observations of treating physicians and others, and an individual’s own description of his limitations.’ ” Krogmeier v. Barnhart, 294 F.3d 1019, 1024 (8th Cir. 2002) (quoting McKinney v. Apfel, 228 F.3d 860, 863 (8th Cir.2000)).
Although a claimant’s RFC is determined at step four of the sequential evaluation process, where the burden of proof rests on the claimant, the ALJ bears the primary responsibility for determining a claimant’s RFC. Id. As noted, an RFC is based on all relevant evidence, but it “remains a medical question” and “ ‘some medical evidence must support the determination of the claimant’s [RFC].’ ” Id. at 1023 (quoting Hutsell v. Massanari, 259 F.3d 707, 711 (8th Cir.2001)). The ALJ is therefore required to consider- at least some supporting evidence from a medical professional. Lauer v. Apfel, 245 F.3d 700, 704 (8th Cir.2001).
Plaintiff claims that, in determining plaintiffs mental RFC, the ALJ improperly rejected the opinion of consultative psychologist Dr. Lipsitz. In analyzing medical evidence, “[i]t is the ALJ’s function to resolve conflicts among ‘the various treating and examining physicians.’ ” Johnson v. Apfel, 240 F.3d 1145, 1148 (8th Cir.2001) (quoting Bentley v. Shalala, 52 F.3d 784, 787 (8th Cir.1995)). “Ordinarily, a treating physician’s opinion should be given substantial weight.” Rhodes v. Apfel, 40 F.Supp.2d 1108, 1119 (E.D.Mo.1999) (quoting Metz v. Shalala, 49 F.3d 374, 377 (8th Cir.1995)). Further, a treating physician’s opinion will typically be given controlling weight when the opinion is “well-supported by medically acceptable clinical and laboratory diagnostic techniques and is not inconsistent with the other substantial evidence in [the] record.” Prosch v. Apfel, 201 F.3d 1010, 1012-1013 (8th Cir.2000) (quoting 20 C.F.R. § 404.1527(d)(2) (bracketed material in original)). Such opinions, however, do “not automatically control, since the record must be evaluated as a whole.” Id. at 1013 (quoting Bentley, 52 F.3d at 785-786). Opinions of treating physicians may be discounted or disregarded where other “medical assessments ‘are supported by better or more thorough medical evidence.’ ” Id. (quoting Rogers v. Chater, 118 F.3d 600, 602 (8th Cir.1997)).
Whatever weight the ALJ accords the treating physician’s report, be it substantial or little, the ALJ is required to give good reasons for the particular weight given the report. See Holmstrom v. Massanari, 270 F.3d 715, 720 (8th Cir.2001). The ALJ, however, is not required to discuss every piece of evidence submitted. See Morrison v. Apfel, 146 F.3d 625, 628 (8th Cir.1998). If the opinion of a treating physician is not well supported or is inconsistent with other evidence, the ALJ must consider: (1) the length of the treatment relationship and the frequency of examination, (2) the nature and extent of the treatment relationship, including the treatment provided and the kind of examination or testing performed, (3) the degree to which the physician’s opinion is supported by the relevant evidence, (4) consistency between the opinion and the record as a whole, (5) *942whether or not the physician is a specialist in the area upon which an opinion is rendered, and (6) other factors which may contradict or support the opinion. See Rhodes, 40 F.Supp.2d at 1119; 20 C.F.R. § 404.1527(d)(2)-(6).
Plaintiff saw Dr. Lipsitz for consultative examinations on three occasions. Plaintiff first saw Dr. Lipsitz on September 28, 2007, at which time Dr. Lipsitz diagnosed plaintiff with bipolar disorder and PTSD, and assessed a GAF score of 53. (Tr. 412). Dr. Lipsitz expressed the opinion that plaintiff was able to understand and remember instructions, and sustain concentration and persistence with tasks; but found that plaintiff was having some difficulty interacting socially and adapting to his environment. (Tr. 413). Dr. Lipsitz found that plaintiff had moderate difficulties in his activities of daily living, and in maintaining social functioning; and mild deficiencies of concentration, persistence, or pace. (Tr. 413). Plaintiff saw Dr. Lipsitz for a second psychological consultation on March 18, 2008, at which time Dr. Lipsitz diagnosed plaintiff with bipolar disorder, and assessed a GAF sore of 55. (Tr. 487). Dr. Lipsitz found that plaintiff was able to understand and remember instructions, and sustain concentration and persistence with tasks; however plaintiff was having difficulty interacting socially and adapting to his environment. (Id.). Dr. Lipsitz expressed the opinion that plaintiff had moderate difficulties in his activities of daily living, and in maintaining social functioning; and mild deficiencies of concentration, persistence, or pace. (Tr. 489). Plaintiff saw Dr. Lipsitz for the third time on July 27, 2009, following the initial administrative hearing. (Tr. 540-42). Dr. Lipsitz diagnosed plaintiff with bipolar disorder, and a GAF score of 50. (Tr. 542). Dr. Lipsitz found that plaintiff had moderate restrictions in activities of daily living, moderate difficulties in maintaining social functioning, and mild deficiencies of concentration, persistence, or pace. (Tr. 543). Dr. Lipsitz expressed the opinion that plaintiff had a marked restriction in his ability to respond appropriately to usual work situations and changes in a routine work setting, and moderate restrictions in his ability to interact appropriately with the public, interact appropriately with supervisors, and interact appropriately with co-workers. (Tr. 545).
The ALJ discussed Dr. Lipsitz’s findings in detail. (Tr. 15-16). The ALJ then indicated that he was assigning less weight to the opinion of Dr. Lipsitz and the other consultative psychologist, Dr. Dempsey, and more weight to the opinion of treating psychiatrists Drs. Gavirneni and Canale. (Tr. 19). The ALJ found that the opinion of Dr. Lipsitz was inconsistent with the opinion of plaintiffs treating psychiatrists and other evidence in the record. (Id.).
The undersigned finds that the ALJ properly analyzed the opinion of Dr. Lipsitz and the other medical opinion evidence. The ALJ reasonably accorded more weight to the opinions of Drs. Gavirneni and Canale, plaintiffs treating psychiatrists who had seen plaintiff many times, than the opinion of Dr. Lipsitz, a consultative psychologist who had seen plaintiff on three occasions. See 20 C.F.R. § 404.1527(d) (factors to consider in weighing medical opinions). See also Ghant v. Bowen, 930 F.2d 633, 639 (8th Cir.1991) (treating physician’s opinion should not ordinarily be disregarded and is entitled to substantial weight).
Dr. Canale was plaintiffs treating psychiatrist from January 2005 through October 2007. At his initial evaluation in January 2005, plaintiffs affect was anxious, but his flow of thought was normal, his memory was intact, and his insight and judgment were good. (Tr. 433). Dr. Canale diagnosed plaintiff with probable bipolar *943disorder and started him on Lamictal. (Id.). On March 13, 2006, Dr. Canale found that plaintiff was doing great on Abilify. (Tr. 434). On September 11, 2006, Dr. Canale noted that plaintiff was doing good, was working full-time, and was not depressed. (Tr. 435). On March 5, 2007, plaintiff had no psychiatric complaints. (Id.). On October 22, 2007, Dr. Canale found that plaintiff was doing good. (Tr. 480). Dr. Canale noted that plaintiff had applied for disability benefits. (Id.).
Plaintiff started seeing Dr. Gavirneni on June 23, 2008, at which time Dr. Gavirneni found that plaintiffs mood was good, his affect was blunt, and his insight and judgment were fair. (Tr. 508). Dr. Gavirneni diagnosed plaintiff with bipolar disorder type I with psychosis, and assessed a GAF score of 60. (Id.). On December 8, 2008, Dr. Gavirneni indicated that plaintiffs mood was stable, plaintiff had no suicidal or homicidal ideations or delusions, his mood was good, his affect was euthymic, and his insight and judgment were fair. (Tr. 506). On March 2, 2009, plaintiff reported that he had applied for volunteer construction jobs. (Tr. 505). Dr. Gavirneni noted that plaintiffs mood was stable, and that he was tolerating his medications well. (Id.). Dr. Gavirneni found that plaintiffs mood was good, his affect was euthymic, and his insight and judgment were fair. (Id.). Dr. Gavirneni authored a letter on April 16, 2009, for the purpose of allowing plaintiff to avoid jury duty. (Tr. 504). In this letter, Dr. Gavirneni stated that plaintiff easily became overwhelmed in stressful situations due to his severe psychiatric condition and that plaintiff “could easily deteriorate emotionally if forced to perform jury duty.” (Id.). Finally, plaintiff saw Dr. Gavirneni on September 28, 2009, approximately two months after Dr. Lipsitz’s last examination, at which time Dr. Gavirneni stated that plaintiff was doing well, and that his mood was stable. (Tr. 547). Dr. Gavirneni found that plaintiffs mood was good, his affect was euthymic, and his insight and judgment were fair. (Id.).
The ALJ noted that Dr. Gavirneni’s treatment notes reveal that plaintiffs mental status was stable and that plaintiff had no significant adverse side effects from medications. (Tr. 19). The ALJ stated that, other than Dr. Gavirneni’s April 2009, which was obviously written solely for the purpose of excusing plaintiff from jury duty, nothing in Dr. Gavirneni’s treatment notes indicate that plaintiff was incapable of working. (Id.). In fact, Dr. Gavirneni’s treatment notes reveal that plaintiff had applied for construction jobs in March 2009. (Tr. 505). The ALJ pointed out that Dr. Gavirneni’s treatment notes from September 2009, in which Dr. Gavirneni indicates that plaintiff was doing well and his mood was stable, refute any implication from Dr. Lipsitz’s July 2009 report that plaintiffs condition deteriorated. (Tr. 19, 547). The ALJ noted that Dr. Reed, the medical expert, pointed out the same inconsistencies and concluded that the mildly restrictive GAF score of 60, assessed by Dr. Gavirneni in June 2008, was the prevailing one. (Tr. 19, 80). The ALJ pointed out that Dr. Reed found that plaintiff had only mild limitations in term of personal interaction and concentration, and should not be precluded from performing unskilled work. (Id.).
The ALJ acknowledged that psychologist Dr. Dempsey expressed the opinion on May 1, 2009 that plaintiff was mentally disabled for the purpose of receiving state public assistance. (Tr. 19, 532-35). The ALJ found that this decision was also inconsistent with the records of plaintiffs treating psychiatrists, for the same reasons discussed with regard to Dr. Lipsitz. (Tr. 19). The ALJ also noted that the finding by the State of Missouri that plaintiff was disabled for the purpose of qualify*944ing him to receive public assistance was not entitled to great weight in this proceeding. (Id.). As properly noted by the ALJ, a determination made by any nongovernmental or any other governmental agency that a claimant is disabled is based on its own rules, and is not binding on the Commissioner. See 20 C.F.R. §§ 404.1504, 416.904; Cruze v. Chater, 85 F.3d 1320, 1325 (8th Cir.1996) (claimant’s designation as disabled under state law is not binding on the Commissioner).
In determining plaintiffs RFC, the ALJ also performed a proper credibility analysis. The ALJ noted that plaintiff maintained a good range of activities and still had some friends with whom he associated, notwithstanding his mental diagnosis. (Tr. 19). Significant daily activities may be inconsistent with claims of disabling pain. See Haley v. Massanari, 258 F.3d 742, 748 (8th Cir.2001).
The ALJ next noted that plaintiffs last job did not end for medical reasons but, rather, ended for economic reasons when plaintiff was laid-off. (Tr. 19). In fact, although plaintiff was diagnosed with bipolar disorder in January 2005, plaintiff was able to work until he was laid off in July 2007. The fact that a claimant worked successfully for a significant period of time with his or her impairments is inconsistent with a claim of a disabling impairment. See Orrick v. Sullivan, 966 F.2d 368, 370 (8th Cir.1992). The ALJ also pointed out that plaintiff received unemployment benefits for three quarters after he was laid off, which was inconsistent with his allegation of disability. (Tr. 18). The application for unemployment benefits requires an assertion of the ability to work and is facially inconsistent with a claim of disability. Cox v. Apfel, 160 F.3d 1203, 1208 (8th Cir.1998); Barrett v. Shalala, 38 F.3d 1019, 1024 (8th Cir.1994).
The ALJ next noted that plaintiff had never required psychiatric hospitalization. Rather, plaintiff only sees his psychiatrist every three to four months for follow-up and maintenance. (Tr. 20). The record indicates an eight-month gap between the time plaintiff last saw Dr. Canale in October 2007, and the time he started seeing Dr. Gavirneni in June 2008. This is an appropriate consideration, because the fact that a plaintiff fails to seek regular medical treatment disfavors a finding of disability. See Gwathney v. Chater, 104 F.3d 1043, 1045 (8th Cir.1997).
Finally, the ALJ noted that plaintiff displayed no obvious signs of depression, anxiety, memory loss, or other mental disturbance at the hearings. (Tr. 20). “While the ALJ’s observations cannot be the sole basis of his decision, it is not error to include his observations as one of several factors.” Lamp v. Astrue, 531 F.3d 629, 632 (8th Cir.2008).
The undersigned finds that the ALJ’s mental RFC determination is supported by substantial evidence. The ALJ’s RFC is supported by the objective medical evidence, including the opinions of the treating psychiatrists and the medical expert, Dr. Reed. After seeking assistance from medical expert Dr. Reed, the ALJ determined that the opinions of the consulting psychologists were inconsistent with the opinions of the treating psychiatrists. Drs. Canale and Gavirneni consistently found that plaintiffs mood was stable and that he was doing well with medication. Dr. Reed expressed the opinion that plaintiff was capable of performing simple, repetitive tasks, with limited interactions with the public, co-workers, and supervisors. (Tr. 82). As such, the ALJ’s mental RFC is supported by the opinion of Dr. Reed and the treatment notes of plaintiffs treating psychiatrists. Further, as previously discussed, the ALJ performed a proper credibility analysis and found that plaintiffs allega*945tions of a disabling mental impairment were not entirely credible. Thus, the ALJ’s mental RFC determination is supported by substantial evidence in the record as a whole.
Plaintiff also argues that the ALJ erred in failing to consider the impact of plaintiffs obesity on his ability to work. The ALJ found that plaintiffs obesity was a medically determinable severe impairment. (Tr. 21). The ALJ then discussed the effect of plaintiffs obesity on his ability to function in the workplace. (Tr. 13-14, 17). The ALJ noted that plaintiff was very obese, weighing over 336 pounds, which would have qualified him for disability due to obesity under the former regulations. (Tr. 13). The ALJ found that, although plaintiffs obesity contributed to some diminution in ordinary mobility and stamina, there was no credible evidence that plaintiffs obesity, either by itself or in combination with other medically-established impairments, reduced plaintiffs overall functional abilities any further than the light range of work found by the ALJ. (Tr. 14).
The medical evidence supports the ALJ’s determination. While the record reveals that plaintiff has been diagnosed with morbid obesity, there is no evidence of arthritis, chronic knee pain, or chronic back pain. Plaintiff has reported occasional pain due to injuries, but there is no evidence of chronic musculoskeletal pain. For example, in May 2007,- plaintiff reported pain with range of motion in the left ankle due to dropping a concrete block on his foot the previous day. (Tr. 361). Plaintiffs musculoskeletal examination was otherwise normal. (Id.). At all three of his consultative examinations, Dr. Lipsitz noted that plaintiff had no difficulties with posture or gait. (Tr. 410, 485, 540). Plaintiff complained of right knee pain, after twisting his knee when walking in August 2008. (Tr. 523). Plaintiff was instructed to increase his activity at this time. (Id.). In September 2008, plaintiff denied any lower extremity pain. (Tr. 519). In February 2009, plaintiff had no musculoskeletal complaints. (Tr. 516). In March 2009, plaintiff complained of left knee pain due to a fall. (Tr. 512). No swelling was observed upon examination. (Id.). In April 2009, plaintiff reported that his knee was “back to normal.” (Tr. 511).
The ALJ properly considered plaintiffs obesity in determining plaintiffs RFC. The ALJ limited plaintiff to light work with additional environmental limitations due to his severe impairments of obesity, asthma, hypertension, hypothyroidism, and sinusitis. (Tr. 21). The medical record reveals that plaintiffs obesity did not cause any chronic musculoskeletal complaints that would result in additional limitations. Plaintiff has failed to point to any evidence supporting his claim that plaintiff was more limited due to his obesity. Plaintiff testified at the initial administrative hearing that he was able to lift twenty pounds, which is consistent with the performance of light work. (Tr. 53). The ALJ included additional environmental limitations due to plaintiffs asthma and sinusitis. Thus, the undersigned finds that the physical RFC formulated by the ALJ is supported by substantial evidence in the record as a whole.
After properly determining plaintiffs RFC, the ALJ elicited testimony of a vocational expert to assist him in determining the demands of plaintiffs past work and in comparing plaintiffs past work with his RFC. The ALJ determined that plaintiff retained the RFC to perform past relevant work as a production assembler, and that plaintiff was not, therefore, disabled. (Tr. 21).
Conclusion
Substantial evidence in the record as a whole supports the decision of the ALJ *946finding plaintiff not disabled because the evidence of record supports the ALJ’s finding that plaintiff was capable of performing his past relevant work. Accordingly, Judgment will be entered separately in favor of defendant in accordance with this Memorandum
