You worked hard. You lost the weight. Your health started improving.
So why does maintaining that weight loss sometimes feel harder than losing it?
The answer is not simply willpower.
After weight loss, the body undergoes biological adaptations that can make maintaining a lower weight challenging. Hunger may increase, energy expenditure may decrease, and the brain’s appetite-regulating systems may begin pushing back.
In Episode 2 of the Dr. Green Obesity Series, we explore the science behind weight regain and why obesity requires more than a short-term weight-loss plan.
🔬 In this episode, we explore:
✅ Why the body may resist maintaining weight loss
✅ How leptin, ghrelin, and appetite regulation change
✅ Adaptive thermogenesis and reduced energy expenditure
✅ Why increased appetite may be a stronger biological response than reduced calorie expenditure
✅ What the 2016 Polidori–Hall study revealed about appetite after weight loss
✅ What the STEP 1 and STEP 4 semaglutide studies teach us about weight loss, treatment withdrawal, and weight regain
✅ Why the body’s “weight set point” is more complex than a fixed number
✅ How to develop a long-term weight-maintenance strategy
We also follow Sarah, a fictional patient who has achieved meaningful weight loss and is now facing a different challenge: maintaining the improvements she has worked so hard to achieve.
The central message:
Regaining weight is not necessarily evidence of personal failure. Biological mechanisms can make long-term weight maintenance difficult, and successful obesity management may require ongoing nutritional, behavioral, physical activity, and medical support.
Reaching a healthier weight doesn’t necessarily mean the journey is finished. Maintaining the improvement can be another phase of treatment.
