Energy balance
Exercise attenuates weight regain after weight loss by counteracting biological adaptations (reducing intake and elevating expenditure), but its effectiveness depends on adherence and individual responder status.
Exercise is a powerful tool to counter the biological drive to regain weight, but it requires consistency. If you struggle with adherence, focus on making exercise sustainable rather than intense. Be aware that you might eat more after exercising, so monitor your intake.
GoodQualifiesMEDIUM confidence
Preclinical studies in weight reduced animal models of obesity have shown that both volitional and regimented exercise attenuate weight regain after weight loss... and counter the biological factors that promote weight regain by reducing intake and elevating expenditure.
Why this rating
Supported by preclinical animal models and some human observational data, though RCTs are limited by adherence issues.

More from this paper
- Weight loss triggers physiological adaptations (increased appetite, decreased energy expenditure) and behavioral shifts (declining adherence) that create a biological pressure to regain lost weight, making maintenance significantly harder than initial loss.Strong
- Leptin replacement or sensitization can counter adaptive responses to weight loss (increased appetite, decreased expenditure) and may be effective for weight loss maintenance when targeted to the right individuals.Good
