Sleep restriction increases the appeal of sweet/dessert foods and activates the endocannabinoid system (2-AG), driving hedonic food intake and obesity risk.
If you are sleep-deprived, you are biologically wired to crave sweets. Recognize this as a hormonal response, not a lack of willpower, and plan your snacks accordingly.

More from this paper
- Insufficient sleep and circadian misalignment act as novel, modifiable risk factors for obesity by altering hunger hormones (ghrelin, 2-AG), increasing hedonic food appeal, and reducing energy expenditure.Good
- Time-Restricted Feeding (TRF) restricts food intake to a specific window (e.g., 12 hours) and serves as an effective countermeasure to prevent obesity induced by circadian misalignment (shift work/jet lag) and high-fat diets.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
