TL;DR
Low-carb diets effectively promote short-term fat loss by reducing glycogen stores and increasing fat burning, aided by higher protein and fat intake to curb hunger. While initial weight loss mainly reflects water loss, sustained adherence can improve blood sugar control and support fat reduction. Careful management of electrolytes and balanced nutrition optimize results, though long-term effects require further study.

What is a Low-Carb Diet?
Low-carb diets restrict carbohydrate intake such as sugar, bread, pasta, and starchy vegetables. They emphasize unprocessed foods like lean proteins, healthy fats, and non-starchy vegetables to reduce calories and enhance metabolism.
How Does a Low-Carb Diet Work for Fat Loss?
Reducing carbohydrates first depletes glycogen stores, causing water loss initially. When glycogen is low, the body switches to burning fat for energy. High protein and fat increase fullness, reduce hunger, and improve blood sugar regulation. For people with diabetes, low-carb diets may help manage blood sugar better.
