Carbohydrates are one of the three major nutrients found in food. Unlike protein and fat, which have other functions, their only role is providing energy for your body.
Low-carb diets — true to their name — contain very few carbohydrates (affectionately known as carbs), which are mostly found in sugary and starchy foods. These diets also provide adequate protein and more fat than a low-fat diet.
You’d have to be hiding from the internet altogether not to have heard about “keto diets,” but that term is really meant for only the strictest form of a low-carb diet. LCHF (low-carb, high-fat) is another name for these diets. Hearing about other people and celebrities losing weight on low-carb diets might make them sound like they’re just the latest fad, but there’s a lot more to these diets than that.
