👖 How many calories should I eat on Ozempic?

The fork goes down before the plate is empty. Not because you decided to stop — because something already decided for you.

Millions of Americans are now on GLP-1 medications. Most of them are eating less than they ever have. That part is working.

While on Ozempic (semaglutide), most adults should aim for a daily caloric intake that creates a moderate deficit — typically 500–750 kcal below their maintenance needs. Semaglutide reduces appetite and food intake, but individual requirements depend on age, sex, weight, activity level, and health goals.

Semaglutide leads to a mean weight loss of 11–15% over 68 weeks, primarily by reducing appetite and food intake. In clinical trials, participants on semaglutide followed a diet with a 500–750 kcal/day deficit alongside the medication, achieving greater weight loss than placebo. Energy needs vary by individual, but a moderate caloric deficit is standard for safe, sustainable weight loss.

Semaglutide reduces body weight by 11.85% in non-diabetic obese adults, mainly via decreased caloric intake. In the STEP 2 trial, participants on semaglutide followed a diet with a 500–750 kcal/day deficit, achieving greater weight loss than placebo. Semaglutide acts on GLP-1 receptors in the brain to suppress appetite and lower spontaneous energy intake.

Calorie restriction for weight loss has been a cornerstone of obesity treatment since the early 20th century. GLP-1 agonists like semaglutide represent a new era in medical weight management, first approved for diabetes and later for obesity. The concept of caloric balance and its role in health and longevity has roots in early nutrition science research.

Track your daily calories using a food scale and nutrition app to ensure you maintain the recommended deficit. Prioritize high-protein, high-fiber foods to enhance satiety, as semaglutide may make it easier to stick to lower calorie goals. Plan meals in advance to avoid unintentional overeating, especially as semaglutide can blunt hunger cues.
