Energy balance

Counter-regulatory mechanisms, specifically adaptive thermogenesis and increased eating drive, are potent physiological responses to weight loss that actively promote weight regain, thereby limiting the long-term efficacy of lifestyle interventions and pharmacotherapies.

When you lose weight, your body fights back by lowering your metabolic rate and increasing hunger. This is a normal biological response, not a personal failure. To maintain weight loss, you must anticipate this metabolic adaptation and likely require ongoing, structured support rather than relying on initial willpower alone.

Potent counter-regulatory mechanisms where changes in energy intake (EI) or energy expenditure (EE) act reciprocally lead to the failure of dieting and exercise as a treatment option for overweight and obesity.
