¶ 1. This case requires us to determine whether placing an inmate on a Nutraloaf-and-water diet in response to misconduct constitutes “punishment” within the meaning of 28 V.S.A. § 851, thereby requiring a hearing prior to implementation of the diet under § 852. This case does not present the question of whether the imposition of such a diet is cruel and unusual punishment, or even whether its substitution for standard prison fare is a deprivation significant enough to trigger the protection of constitutional due process guarantees. Nor does this case challenge the imposition of a Nutraloaf-and-water diet per se. Rather, this case presents the fairly pedestrian question of what the Legislature meant when it commanded the Department of Corrections to afford inmates the fact-finding hearing described in § 852 prior to punishment. The superior court concluded that the Nutraloaf-and-water diet is not punishment, and thus is not subject to the hearing process required by statute. We hold that the Nutraloaf-and-water diet is punishment within the meaning of § 851 that may be imposed only in accordance with the statutory provisions found in §§ 851-853.
¶2. Petitioners are inmates in the custody of the Vermont Department of Corrections who challenge the Department’s practice of placing inmates on a diet of Nutraloaf, without a hearing, *488in response to inmates’ abuse of food, utensils, or bodily waste. Nutraloaf consists of a compost of whole wheat bread, nondairy cheese, carrots, canned spinach, raisins, canned Great Northern beans, vegetable oil, tomato paste, powdered milk, and potato flakes, mashed together and baked in a loaf pan.
¶ 8. Petitioners brought this declaratory-judgment action in superior court. The trial court denied the petition, concluding that the Nutraloaf diet was not a punishment. The trial court found that Nutraloaf was designed to be “less appealing than normal food,” and that “[t]he Department could give other food (such as sandwiches) that would not require utensils, plates or cups.” However, the trial court reasoned that “the effectiveness of the program would be undermined if the meals were appealing to the point of providing an incentive for misbehavior.” The court further determined that “[t]he primary goal of the Nutraloaf program is to limit an inmate’s ability to misuse food, utensils, or bodily wastes, by eliminating utensils, by presenting the food in a form that is less messy, and also perhaps by reducing the available bodily wastes by imposing a high-fiber diet.” Finally, the trial court concluded that the evidence that the Department intended Nutraloaf as punishment was not strong, that the Department had “legitimate non-punitive purposes” for implementing the program, and that “the punitive aspects of the program will not be excessive in relation to its purposes.”
¶ 4. The Nutraloaf diet is authorized by Departmental Directive 413.09, “Special Management Meals in Facilities.” Directive 413.09 recites that it was promulgated to “reduce or limit the ability of inmates to misuse bodily waste or food (including utensils) which may pose a risk to other inmates and staff.” The directive defines the “misuse of food or bodily waste” as:
Disruptive behaviors by inmates that involve mishandling of food or bodily waste including, but not limited to, assaulting others with food or bodily waste; smearing of bodily waste on persons or property or other mishandling of food or bodily waste; use of utensils as weapons or other tools for which they were not intended; refusal to return utensils; and tampering with or jamming the food slot.
In accordance with this provision, when an inmate engages in the offending behavior, prison officials are authorized — after assess*489ing whether other attempted interventions such as warnings have occurred — to place the inmate in administrative segregation and on a “special management meal” regime. On this regime, an inmate is served Nutraloaf in lieu of standard prison fare three times daily, for a maximum of seven days, during which time the inmate may remain hydrated by drinking water out of a tap in his or her cell. It is uncontroverted that Nutraloaf is nutritionally adequate to sustain life.
¶ 5. The directive anticipates that inmates may continue the offending behavior after imposition of the Nutraloaf-and-water regime. The directive requires that “[a]n inmate’s progress will be reviewed by a Shift Supervisor within three (3) calendar days, and if the disruptive behavior stops before the end of the period imposed, the Shift Supervisor may return the inmate to regular meals.” Pursuant to the directive, “in making decisions to continue [] placement” on the diet, the supervisor is to “consider circumstances such as . . . the continued display of the original behavior.”
¶ 6. The record does not reveal how much time elapses between detection of the offending behavior and imposition of the loaf regime. The directive requires that the Nutraloaf diet “be implemented as soon as possible after the disruptive behavior has taken place, to achieve the greatest level of behavior change.” However, pursuant to the directive, several steps must be taken before serving an inmate his or her first loaf. Staff who observe an inmate misusing food or bodily waste are to report their observations to the shift supervisor by filling out and relaying certain paperwork. After considering “any precipitating events and other attempted interventions,” if the supervisor decides that a Nutraloaf diet constitutes an appropriate consequence for the offending behavior, he or she relays a written recommendation to the superintendent and to the facility physician for approval. If the inmate has a serious mental illness, the physician will consult with the psychiatrist prior to approving the diet. The written approval of the physician and the superintendent is required prior to the imposition of the regime. After the decision has been made to put an inmate on a Nutraloaf-and-water diet, prison staff provides the inmate with written information about the procedure, including an explanation as to why the inmate is being placed on the diet, the schedule of daily servings, the nutritional content of *490the meal, and a recommendation that the inmate drink “plenty” of water.1
¶ 7. While the other procedures associated with serving Nutraloaf vary depending on circumstance — namely, whether an inmate committed the offending behavior while already in either administrative or disciplinary segregation for an unrelated infraction — it is uncontroverted that in no circumstance does the Department afford an inmate the opportunity to contest the factual predicate for the implementation of the diet via the procedures outlined in § 852. Rather, as the trial court found, the Department imposes the regime “unilaterally.”
¶ 8. As noted, this case presents only the question of whether the Nutraloaf-and-water diet is a “punishment” requiring the statutory protections provided by §§ 851-85S.2 Section 851 states that no “punishment [shall] be imposed otherwise than in accordance with the provisions of this subchapter.” Id. § 851. Section 852 requires that “[i]n disciplinary cases . . . [the Department] shall conduct a fact-finding hearing” prior to punishment, at which the inmate is entitled to notice of the charge, to confront the person bringing the charge, to testify, and to question witnesses. Id. § 852(b). Section 853 describes the types of punishment that may be imposed by the disciplinary committee when an inmate breaks prison rules. Id. § 853. Punishment for a breach of the rules and regulations of the facility generally consists of the deprivation of privileges. Id. § 853(a)(1). For “serious breaches,” the disciplinary committee may recommend a variety of sanctions, including the deprivation of privileges or placement in a disciplinary segregation unit. Id. § 853(a)(2).
¶ 9. The question of whether the imposition of the Nutraloaf- and-water diet is a “punishment” within the meaning of § 851 requires us to review both the trial court’s legal conclusions and *491its factual findings. While the trial court’s conclusions as to issues of law will be reviewed de novo, we will not disturb its factual findings unless clearly erroneous. V.R.C.P. 52(a)(2); Elkins v. Microsoft Corp., 174 Vt. 328, 330, 817 A.2d 9, 12 (2002) (“To the extent that our review of the trial court’s decision involves questions of statutory construction, and thus questions of law, it is nondeferential and plenary.”).
¶ 10. In construing § 851 anew, we keep in mind the following principles of construction: “we look first to the plain, ordinary meaning of the language,” “[w]e construe closely related statutes together as part of one system,” and “[w]e defer to the construction of a statute by the agency responsible for implementing it.” State v. Rolfe, 166 Vt. 1, 7, 686 A.2d 949, 954 (1996) (quotation omitted).
¶ 11. Upon review of a trial court’s factual findings, findings of fact are clearly erroneous if internally inconsistent. See Aponte v. Calderon, 284 F.3d 184, 194 (1st Cir. 2002) (noting that internally inconsistent factual findings are clearly erroneous under identical federal standard set forth in Federal Rule of Civil Procedure 52(a)); Mendiola v. United States, 994 F.2d 409, 410 (7th Cir. 1993) (“Findings are clearly erroneous if the trial court’s interpretation of the facts is implausible, illogical, [or] internally inconsistent . . . .”). In particular, when subsidiary factual findings are inconsistent with ultimate factual findings, the ultimate factual finding may not stand. Aponte, 284 F.3d at 194 (when subsidiary factual findings are inconsistent with ultimate factual findings, the ultimate finding is clearly erroneous); Alfaro De Quevedo v. De Jesus Schuck, 556 F.2d 591, 593 (1st Cir. 1977) (same). We address the trial court’s legal conclusions and factual findings in turn.
¶ 12. We have had occasion to construe § 851 before; in Conway v. Cumming, we held that revoking a prisoner’s furlough status was not “punishment” within the meaning of § 851. 161 Vt. 113, 119, 636 A.2d 735, 738 (1993). In so holding, we adopted the test used by the United States Supreme Court to evaluate a similar question in Bell v. Wolfish, 441 U.S. 520 (1979). In Bell, the Court examined whether certain correctional facility practices — including double-bunking pretrial detainees in single-person cells — converted pretrial detention into preprocess “punishment” in violation of the Due Process Clause of the United States Constitution. Evaluating whether this living situation was punitive, *492the Court articulated and applied three criteria. The Bell Court first asked whether the double-bunking was “imposed for the purpose of punishment.” Id. at 538. “Absent a showing of ... intent to punish,” the Court continued, whether the policy constitutes punishment depends on “whether an alternative purpose to which the restriction may rationally be connected is assignable for it, and [finally,] whether it appears excessive in relation to the alternative purpose assigned to it.” Id. (quotation omitted). The Bell Court concluded that the prison’s policy of double-bunking inmates was not intended to punish, and that the practice reasonably served the important governmental objectives of ensuring a defendant’s presence at trial and the need for government to effectively manage prison facilities. Id. at 539-40.
¶ 13. While still incarcerated, the petitioner in Conway had been allowed to make short visits to the community, but this privilege was revoked by the Commissioner without a hearing for negative behavior. 161 Vt. at 114-15, 636 A.2d at 736. The petitioner challenged this revocation, claiming that it was punishment and that he was therefore entitled to the procedural protections codified in § 852. We examined the three Bell criteria, focusing on the Supreme Court’s holding that “absent an intent to punish, a government decision that is reasonably related to a legitimate governmental purpose is not punishment.” Id. at 119, 636 A.2d at 738. We concluded that revocation of the petitioner’s furlough status was not punishment, though we came to this conclusion without actually applying the three Bell factors. Id. (holding that the petitioner had no liberty interest in a furlough program, nor did he point to any restriction suffered other than continuation of the incarceration to which he was legally sentenced). Such being the case, Conway is of limited assistance — except insofar as it identifies the relevant inquiry — to the question we face today.
¶ 14. Citing Conway, the trial court identified the correct factors for consideration. Applying the first factor, the court concluded that the Nutraloaf-and-water diet was not imposed for the purpose of punishing inmates. We disagree and hold that the regime constitutes punishment under § 851.
¶ 15. The trial court did not explicitly find that the Nutraloaf regime was without any punitive intent, but concluded that the evidence that the Department intended Nutraloaf as punishment *493was not strong, that the Department had “legitimate non-punitive purposes” for implementing the program, and that “the punitive aspects of the program will not be excessive in relation to its purposes.” We read the trial court’s decision as acknowledging mixed motives on the part of the Department with regard to the Nutraloaf program.
¶ 16. We do not disagree that the Department’s motives were mixed,3 but to the extent that the superior court ultimately found that the Department’s purpose was primarily nonpunitive, the court erred. Consistent with the directive’s stated goal to “reduce or limit” offending behavior, actual prevention of the misuse of food or bodily wastes is not the aim of Nutraloaf. We do not understand the Department to argue to the contrary.4 *494Rather, the program’s implementing directive contemplates that the offending behavior may continue after imposition of the diet. Only if the behavior has ceased within three days of implementation is the supervisor authorized to reintroduce standard prison fare to an offending inmate. This, together with the trial court’s finding that Nutraloaf was designed to be unappetizing, compels the conclusion that deterrence is central to the Nutraloaf program. Prevention aims to remove the means to do something, while deterrence, by contrast, aims to convince a person not to do something that they retain the ability to do. Nutraloaf — a purposefully unappetizing alternative to standard prison food — may be served along with the implements used to commit the targeted malfeasance,5 and under directions that the diet continue until the inmate decides to stop engaging in the offending conduct. We hold that the principal aim of the Nutraloaf program is to deter.
¶ 17. As the United States Supreme Court stated in Kennedy v. Mendoza-Martinez, “retribution and deterrence” are “traditional aims of punishment.” 372 U.S. 144, 168 (1963); see also Strong, 158 Vt. at 59-60, 605 A.2d at 512 (recognizing that deterrence and retribution are punitive governmental objectives). We conclude that the Nutraloaf-and-water regime is classic punitive deterrence.
¶ 18. That there are less restrictive means to achieve the preventative ends of the directive is another indication of the Department’s punitive intent. See Bell, 441 U.S. at 539 n.20 (reasoning that the availability of “less harsh methods” to achieve otherwise legitimate objectives can demonstrate intent to punish). The Department argues that in order to be effective, Nutraloaf must be unappetizing. The Department suggests, and the trial court reasoned, that serving a sandwich — which requires neither a tray nor utensils and therefore has all the preventative qualities of Nutraloaf — would be less effective than Nutraloaf because it could incentivize prohibited conduct where, for example, an inmate did not like what was being served for dinner. While we find this argument to be speculative, see Rust v. Grammer, 858 F.2d 411, 414 (8th Cir. 1988) (evaluating inmates’ claim that temporary diet *495of sandwiches and water was cruel and unusual punishment), this is not its principal weakness. Rather, the Department’s focus on incentives betrays its acknowledgement of the disincentive — or, in other words, deterrent — properties of Nutraloaf.
¶ 19. Courts in other jurisdictions facing similar issues have come to various conclusions. On the one hand, courts evaluating whether Nutraloaf-like diets constitute cruel and unusual punishment have adjudged that similar regimes were “punishment,” albeit of the non-cruel-and-unusual variety. LeMaire v. Maass, 12 F.3d 1444, 1455 (9th Cir. 1993) (upholding district court’s finding that “Nutraloaf was being used punitively to control inmate behavior”); Breazil v. Bartlett, 998 F. Supp. 236, 242 (W.D.N.Y. 1997) (characterizing restrictive diet of Nutriloaf-and-cabbage as “punitive”); United States v. Michigan, 680 F. Supp. 270, 274 (W.D. Mich. 1988) (finding that food loaf is a “punishment” designed to “impress[] inmates with the understanding that extremely unpleasant results will occur whenever they engage in the prohibited behavior”); Arnett v. Snyder, 769 N.E.2d 943, 948-50 (Ill. App. Ct. 2001) (evaluating “punishment” called “meal loaf’ under the Eighth Amendment), petition for leave to appeal denied, 766 N.E.2d 238 (Ill. 2002). Our decision is entirely consistent with these cases.
¶ 20. On the other hand, one federal district court has twice granted summary judgment to state defendants in cases where a loaf diet was challenged on due process grounds. Joseph v. Arpaio, 2008 WL 243690, slip op. at *6 (D. Ariz. 2008) (granting summary judgment to state defendants where plaintiff failed to rebut evidence that loaf program was reasonably related to a legitimate governmental objective); Bugoni v. Coffman, 2006 WL 3333078, slip op. at *9 (D. Ariz. 2006) (reasoning that, based on the summary judgment evidence, the loaf program was not punitive).6
*496 ¶ 21. “Our paramount goal, when interpreting a statute, is to effectuate the intent of the Legislature.” Dep’t of Corr. v. Human Rights Comm’n, 2006 VT 134, ¶ 7, 181 Vt. 225, 917 A.2d 451 (quotation omitted). Therefore, while we appreciate that there have been a variety of judicial responses to challenges — under various legal theories — to Nutraloaf-like programs, we are ever mindful of the fact that, in the end, those judicial responses are not relevant to our ultimate aim. We are confident that the plain and ordinary meaning of “punishment” — to which we are bound — is consistent with our decision today. Rolfe, 166 Vt. at 7, 686 A.2d at 954 (in construing a statute, we look first to the “plain, ordinary meaning” of its language). Indeed, we note that the plain and ordinary meaning of “punishment” is more than broad enough to encompass the Department’s use of Nutraloaf for deterrence. For instance, while Black’s Law Dictionary defines “deterrent punishment” as that which is “intended to deter the offender and others from” malfeasance, it also notes that “preventative punishment” is “intended to prevent a repetition of wrongdoing by disabling the offender.” Black’s Law Dictionary 1270 (8th ed. 2004).
¶ 22. Finally, we are compelled to address the dissent’s parade of horribles. First, the dissent laments that as a result of our decision today, the Department will no longer be able to take “swift, temporary, and entirely unhurtful” action in response to the serious misconduct the Nutraloaf program is designed to address. Post, ¶ 38. There is no basis in the record or in logic for the conclusion that our decision deprives the Department of the ability to take swift action, or the assumption that the Nutraloaf regime is unhurtful. The dissent points to no evidence regarding how swiftly the Department implements the Nutraloaf diet in light of the extensive procedures it already follows prior to the first feeding, see supra, ¶ 6, how long, as a relative matter, compliance with § 852 would take, or the absence of alternative, primarily preventative actions that can be taken without the hearing the dissent assumes is so burdensomely slow. And we find especially curious that the dissent chooses to characterize the Nutraloaf *497regime as “entirely unhurtful,” post, ¶ 38, an assumption in considerable tension with the trial court’s finding that constipation may have been one of Nutraloafs aims, and with the extensive medical follow-up mandated by the regime’s terms.
¶ 23. Second, the dissent claims that our opinion presents the Department with “a Hobson’s choice of either providing misbehaving inmates with their choice of foods that are likely more appetizing than standard prison fare, thereby encouraging the very behavior that it needs to prevent, or simply doing nothing.” Post, ¶ 37. The dissent’s suggestion that our decision requires the Department to give inmates — misbehaving or otherwise — “their choice of foods” is ludicrous. The dissent’s concern that our decision requires the Department to guard against providing disincentives by designing special management meals to be more appetizing than standard prison fare overlooks the fact that it is the Department’s intent, and not the tastiness of the food, that is the focus of our inquiry. In any event, what the dissent calls a “Hobson’s choice”7 is but a false dilemma, for the dissent fails to consider at least one rather obvious option — that in response to inmate misconduct, the Department may serve standard prison fare not requiring utensils and trays until guilt is determined at a § 852 hearing after which the Nutraloaf regime may be implemented. The only true Hobson’s choice facing the Department is its “option” of following the law.
¶ 24. In sum, the Nutraloaf-and-water regime constitutes “punishment” within the meaning of § 851. To hold otherwise would be to turn a blind eye toward the regime in the name of deference to the Department. This we will not do. Before they may be placed on the diet, inmates are entitled to process in accordance with §§ 851-853.
Reversed.
The trial court found that “Nutraloaf requires an extraordinary amount of water in order to appropriately process the food through the body.” While on the Nutraloaf diet, the inmate is encouraged to drink “plenty” of water due to the high fibrous content of the meal. The total fiber content of Nutraloaf is seventy-two grams daily, while the recommended daily intake of fiber is twenty to thirty grams each day.
Petitioners also argue that imposing Nutraloaf without a hearing violates the Vermont Constitution, and that the Department is violating Directive 410.01 by not providing a hearing. Because neither claim was raised below, we need not address these issues on appeal. See In re Ochs, 2006 VT 122, ¶ 16 n.2, 181 Vt. 541, 915 A.2d 780 (mem.) (declining to address Vermont constitutional claim not raised below).
Our acknowledgement that the Department’s motives were mixed does not, as the dissent argues, undermine our decision by virtue of State v. Strong, 158 Vt. 56, 605 A.2d 510 (1992). In Strong, we held that the civil suspension of a driver’s license for driving under the influence was not “punishment” such that the driver’s subsequent prosecution for DUI ran afoul of the Double Jeopardy Clause’s prohibition “against multiple punishments for the same offense.” Id. at 59, 62, 605 A.2d at 512, 514 (quotation omitted). The dissent’s claim that we evaluated “mixed motives” in Strong is misleading. Post, ¶ 29. In Strong, we noted that “[t]he fact that a statute designed primarily to serve remedial purposes incidentally serves the purpose of punishment as well does not mean that the statute results in punishment for double jeopardy purposes.” Id. at 62, 605 A.2d at 514 (quotation omitted). However, that reasoning does not bear on this case.
Strong was a case involving mixed effects rather than mixed motives. In Strong, having concluded that the Legislature intended the penalty to be remedial rather than punitive, we evaluated whether the effects of the statutory scheme were so punitive as to negate the Legislature’s intent — in other words, applying the second and third prongs of the Bell analysis. Id. at 60, 605 A.2d at 513. In so doing, we grappled with the mixed punitive and remedial effects of the civil suspension scheme. Id. at 60-61, 605 A.2d at 513-14. In this case we do not consider the effects of the Nutraloaf regime under Bell because we conclude that the Department’s purpose was primarily deterrence.
We assume that the Department does not intend for Nutraloaf to prevent inmates from misusing their feces by subjecting them to constipation. The trial court did find that “perhaps . . . reducing the available bodily wastes by imposing a high-fiber diet” was among the Department’s aims. However, this finding makes little sense. The Department would be hard pressed to argue that an intentional regime of constipation was even consistent with “minimum standards of respect for human dignity” as required by the prohibition against cruel and unusual punishment. Landman v. Royster, 333 F. Supp. 621, 647 (E.D. Va. 1971); see also Clark-Murphy v. Foreback, 439 F.3d 280, 292 (6th Cir. 2006) (characterizing an inmate’s Eighth Amendment right to food and water as “clearly established”).
Under the directive, “[a]ny food or items that may be used as containers to throw food or bodily waste will be removed from the inmate’s cell.” However, only “[i]f misuse involved utensils,” will “they [] be removed from the food tray.”
The most analogous case to the one at bar is Arnett, in which the court was also faced with a statutory-construction issue. The Arnett court evaluated whether the imposition of a “meal loaf” regime similar to Nutraloaf violated a statute prohibiting “disciplinary restrictions on diet.” 769 N.E.2d at 948 (quotations omitted). The court characterized the diet as “punishment,” but nevertheless upheld “meal loaf’ under the statute. The court appears to have held that only nutritionally inadequate diets, like that of bread-and-water, constitute “disciplinary restrictions on diet” within the meaning of the statute. We note that nutritionally inadequate diets are prohibited as cruel and unusual. See, e.g., Green v. Ferrell, *496801 F.2d 765, 770 (5th Cir. 1986) (“The eighth amendment requires that jails provide inmates with well-balanced meals, containing sufficient nutritional value to preserve health.” (quotation omitted)); Landman, 333 F. Supp. at 647 (holding that bread-and-water diet violates Eighth Amendment). We find limited guidance in this confusing decision.
A Hobson’s choice is “[a]n apparently free choice that offers no real alternative,” after “Thomas Hobson . . . English keeper of a livery stable, from his requirement that customers take either the horse nearest the stable door or none.” American Heritage Dictionary 859 (3d ed. 1992).
