Eating one meal per day (OMAD) can aid short-term weight loss via calorie restriction but is generally not healthy long-term for most people due to risks like nutrient gaps and metabolic strain.
Potential Benefits
OMAD promotes fat burning through prolonged fasting, simplifies eating, and may improve focus or insulin sensitivity in healthy adults short-term.
Key Risks
It spikes hunger hormone ghrelin, raises blood pressure/cholesterol, delays insulin response, and risks deficiencies, fatigue, or muscle loss—especially unsafe for diabetics, heart patients, or women with hormonal issues like PCOD.
Expert Consensus
Studies favor 2-3 balanced meals daily for sustained health over extreme fasting; OMAD often fails long-term and links to higher mortality in some data. Consult a doctor before trying, especially with your gut/PCOD focus.
