Which factor contributes to weight loss in low-carb diets?

The factor that significantly contributes to weight loss in low-carb diets is the suppression of appetite due to ketosis. When carbohydrate intake is drastically reduced, the body enters a state of ketosis, where it begins to burn fat for fuel instead of relying on carbohydrates. This metabolic state not only promotes fat loss but also tends to lead to a decreased appetite. Many individuals report feeling less hungry while in ketosis, making it easier to consume fewer calories overall without the discomfort of feeling deprived.

In contrast, although increasing muscle mass through higher protein intake can support weight loss by enhancing metabolism, it is not the primary mechanism in the context of low-carb diets. Similarly, calorie cycling might enhance metabolic rates but is less relevant within the framework of low-carb diets. Lastly, increased meal frequency can be effective for some, but it doesn't address the unique appetite-suppressing effects of ketosis that are characteristic of low-carb eating patterns. Thus, the appetite suppression caused by ketosis stands out as the most crucial factor in supporting weight loss while following a low-carb diet.
