Obesity is driven by a 'Nutrition Transition' involving three overlapping processes: dietary changes, physical environment changes, and cultural shifts, which must be addressed simultaneously for policy to be effective.
Understand that obesity is not just about food or exercise, but about how our culture, environment, and food systems interact. Effective solutions require changing the environment (e.g., urban design, food availability) and cultural norms, not just individual knowledge.

The Nutrition Transition is not one process but, in our opinion, three transitions of: diet; management of, and human interface with, the physical environment; culture.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
