Adherence

Adherence to a low-carbohydrate diet (defined as ≤130g carbs/day or ≤25% calories) is sustainable long-term and nutritionally adequate, with high adherence rates reported in observational surveys.

To sustain a low-carbohydrate diet long-term, focus on the high satiety provided by fats and proteins. This natural hunger control makes the diet easier to maintain than calorie-restricted low-fat diets. Ensure your diet includes a variety of whole foods to meet all vitamin and mineral needs, as low-carb diets can be nutritionally complete.
