Feeding during the biological rest phase (daytime for mice, nighttime for humans) disrupts circadian alignment and promotes obesity and metabolic disorders, whereas aligning food intake with the active phase restores metabolic rhythms and prevents weight gain.
Align your main meals with your active hours. If you work a standard day, avoid large meals late at night. If you are a shift worker, try to eat during your 'day' (active phase) and fast during your 'night' (rest phase), even if it is daylight outside. This synchronization helps your metabolic organs function efficiently.
feeding an isocaloric high-fat diet at the incorrect circadian time has been shown to result in increased weight gain in mice... feeding wild-type mice ad libitum exclusively during the daytime resulted in greater weight gain than in animals fed exclusively at night.
Why this rating
Based on multiple animal models (mice, rats) and human observational data on shift work and sleep restriction, though direct long-term human RCTs on feeding timing are implied rather than fully detailed.

- 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
