Maintenance of Lost Weight and Long-Term Management of Obesity

Open access
Hall, Kevin D., Kahan, Scott·2018·Medical Clinics of North America

Abstract

Weight loss can be achieved through a variety of modalities, but long-term maintenance of lost weight is much more challenging. Obesity interventions typically result in early weight loss followed by a weight plateau and progressive regain. This review describes current understanding of the biological, behavioral, and environmental factors driving this near-ubiquitous body weight trajectory and the implications for long-term weight management. Treatment of obesity requires ongoing clinical attention and weight maintenance-specific counseling to support sustainable healthful behaviors and positive weight regulation.

    In the model, the simulated patient who plateaued at six months and then regained maintained more than about 70% of initial intervention effort until the plateau.

    “For example, the model-calculated intervention effort for the simulated patient who experiences the weight plateau at six months followed by weight regain (Figure 2, blue curves) maintains more than ~70% of their initial intervention effort until the plateau.”

      The Results describe a weight-loss plateau after 6–8 months followed by regain, and identify Figure 3C as an index of ongoing intervention effort. The Discussion also describes persistent effort over the first six months. Our copy does not state that effort remained above approximately 70% of its initial level; its Figure 2 concerns feedback control during canagliflozin treatment, not the plateau-and-regain example.

    From a calorie balance perspective, a patient who maintains lost weight after the first year may eat only about 100 kcal/d less than one who regains long-term.

    “From a purely calorie balance perspective, a patient who maintains lost weight after the first year of an intervention (Figure 2, orange curves) may be eating only about 100 kcal/d fewer than a patient who experiences long-term weight regain (Figure 2, blue curves).”

      The Introduction (page not provided) says the modelled patients who regained weight returned to their original weight-maintenance diet within the first year. The Conclusions (page not provided) give a general rule relating sustained intake changes to eventual weight changes. Neither passage establishes that a patient maintaining lost weight after year one eats about 100 kcal/day less than a patient who regains it. (LLM, conf=0.82)

      The Results (page unavailable) describe a weight-loss trajectory followed by slow regain: intake was within 100 kcal/day of baseline at the eight-month plateau and practically at baseline after one year. They do not compare patients who maintain weight loss after year one with patients who regain it, or establish a 100 kcal/day difference between those groups. (LLM, conf=0.83)

    Weight-loss-induced appetite signals could cause subconscious biases such as gradually increasing portion sizes.

    “Thus, signals to the brain that increase appetite with weight loss could introduce subconscious biases such as portion sizes creeping upwards over time.”

      In “Set point theory” (page unavailable), the paper says that underfeeding prompts adaptive changes in food intake that return body weight toward its prior level. Its discussion of mindless eating says habitual intake can occur outside awareness. It does not connect weight-loss-induced appetite signals to portion sizes gradually increasing over time.

    In the model, both example women had rapid weight and fat loss after large initial calorie intake reductions, with a modest decrease in calorie expenditure that slowed weight loss.

    “In both women, large decreases in calorie intake at the start of the intervention result in rapid loss of weight and body fat leading to a modest decrease in calorie expenditure that contributes to slowing weight loss.”

      In the Introduction’s ‘Modelling of the dynamics of weight change’ passage (page unavailable), Figure 1D describes two women given low-calorie liquid diets and says the model reproduced their differing rates of weight loss.

    At the model weight plateau, calorie expenditure was less than 200 kcal/d below baseline, while appetite had risen by 400-600 kcal/d and energy intake by 600-700 kcal/d since intervention start.

    The laws of thermodynamics apply to human energy balance and diet composition.

    “The laws of thermodynamics dictate that the energy derived from macronutrients being oxidized via the intricate biochemical pathways of oxidative phosphorylation inside cells can be equated to the values measured by combusting these fuels in a bomb calorimeter.”

  • Studies comparing dietary composition have generally demonstrated modest effects on weight maintenance, with differences between diets attenuating over time, particularly beyond one year.

    “studies comparing dietary composition (e.g., variations in protein content, carbohydrate restriction, or glycemic index) have generally demonstrated modest effects on weight maintenance, with differences between diets attenuating over time, particularly beyond one year”

    From Weight maintenance after discontinuation of GLP-1 therapies (2026) · cites this paper as [61]

    In “The role of diet composition” (page unavailable), the paper says long-term differences between low-fat and low-carbohydrate diets are too small to be clinically significant and finds no clear long-term superiority among diets. It also notes possible benefits of higher-protein, low-glycemic-index diets and greater short-term weight loss with low-carbohydrate diets. These passages support generally modest long-term differences, but do not establish that differences attenuate over time specifically beyond one year. (LLM, conf=0.84)

  • Higher protein diets (1.2-1.6 g/kg of adjusted bodyweight versus standard 0.8 g/kg) may prevent metabolic adaptation.

    “Higher protein diets (1.2–1.6 g/kg of adjusted bodyweight versus standard 0.8 g/kg) may prevent this type of metabolic adaptation”

    From Lifestyle Medicine for Obesity in the Era of Highly Effective Anti-Obesity Treatment (2025) · cites this paper as [270]

    In “The role of diet composition” (page not provided), the paper says dietary protein has a small positive effect on resting metabolism and that higher-protein diets may help maintain weight loss. It does not say they prevent metabolic adaptation or specify 1.2–1.6 g/kg of adjusted bodyweight versus 0.8 g/kg. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Behavioral approaches (strengthening satisfaction with outcomes, relapse prevention training, cognitive restructuring, developing cognitive flexibility, appealing to deeper motivations, and managing expectations) are helpful for preventing weight regain.

    “Some behavioral approaches to weight loss that have been shown to be helpful for preventing weight regain include strengthening satisfaction with outcomes, relapse prevention training, cognitive restructuring, developing cognitive flexibility, appealing to deeper motivations, and managing expectations”

    From Lifestyle Medicine for Obesity in the Era of Highly Effective Anti-Obesity Treatment (2025) · cites this paper as [270]

    The Clinical recommendations section discusses all six approaches as strategies for long-term weight management. But its overview says research on maintenance-specific training is mixed, and the “Manage expectations” subsection says evidence is mixed on whether unrealistic expectations deter success. The claim overstates the evidence by saying all six have been shown to prevent weight regain. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • During the weight maintenance phase, weight regain can occur secondary to decreased energy expenditure and increased energy efficiency, which together result in a net decrease in caloric needs.

    “During the weight maintenance phase, weight regain can occur secondary to decreased energy expenditure and increased energy efficiency, which together result in a net decrease in caloric needs5–8.”

    From Orforglipron for maintenance of body weight reduction: the double-blind, randomized phase 3b ATTAIN-MAINTAIN trial (2026) · cites this paper as [6]

    The “Physiological responses to weight loss” section (page unavailable) reports declining energy expenditure after weight loss, and “Weight regain versus maintenance” says that preventing regain requires sustained effort against ongoing metabolic slowing and increased appetite. The copy does not identify increased energy efficiency as a separate contributor to reduced caloric needs; it also emphasizes increased appetite as an important driver of regain. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Non-pharmacological interventions to reduce weight in a general population have shown only transient effect on obesity.

    “Non-pharmacological interventions to reduce weight in a general population have shown only transient effect on obesity (8).”

    From Reversibility of Antipsychotic-Induced Weight Gain: A Systematic Review and Meta-Analysis (2021) · cites this paper as [8]

    The Introduction reports that weight regain is typical, and the section “Long term benefits require long term attention” says short-term interventions are unlikely to sustain benefits without ongoing support. But the paper also reports that continued behavioral support improves long-term weight maintenance, so “only transient effect” overstates its conclusion about non-pharmacological interventions. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
