Long-term body weight regulation is achieved through the control of meal size rather than meal frequency or timing, mediated by adiposity signals (leptin and insulin) that modulate sensitivity to meal-ending signals like CCK.
Stop worrying about how many times you eat per day. Your body regulates long-term weight by adjusting how much you eat in each sitting based on your current fat stores. If you are underweight, your body naturally reduces the effectiveness of fullness signals, leading to larger meals. If you are overweight, you naturally eat smaller meals. Focus on consistent food availability and listening to your body's natural satiety cues rather than enforcing arbitrary meal frequencies.
Energy homeostasis, the long-term matching of food intake to energy expenditure, is accomplished via controls over the size of meals. Individuals who have not eaten sufficient food to maintain their normal weight have lower levels of adiposity signals (leptin and insulin) in the blood and brain, and one consequence is that meal-generated signals (such as CCK) are less efficacious at reducing meal size.

- Adiposity signals, specifically leptin and insulin, act as afferent information to the brain to regulate long-term body fat levels by modulating the sensitivity of meal-terminating signals.Strong
- Meal timing and frequency are largely determined by environmental cues, learning, and opportunity rather than immediate physiological energy deficits.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
