Is One Meal a Day Unhealthy? (EP 117)
Could one meal a day help you lose weight? Maybe. But feeling hungry, run-down, and stressed about food is not exactly the definition of healthy, so Uncle Marv digs into what OMAD can do, what it cannot prove, and what a more realistic middle ground may look like.
OMAD, short for One Meal a Day, sounds wonderfully simple on paper. One meal, fewer decisions, less cooking, maybe fewer calories. But simple is not always the same thing as sustainable. Uncle Marv looks past the dramatic claims and asks the practical questions: Can you get enough protein, fiber, fruits, vegetables, healthy fats, vitamins, minerals, and total energy in one sitting without feeling miserable afterward?
The research is not a clean win for either side. Some short-term studies found weight and fat loss benefits, while others found more hunger and increases in blood pressure and cholesterol. Broader intermittent-fasting research suggests that fasting can work as a way to reduce calories, but it has not clearly beaten ordinary, sustainable calorie control for long-term health. The real goal is not joining Team OMAD or Team Three Meals a Day. It is finding an eating pattern that supports your health, strength, sleep, medication needs, and sanity around food.
