Let's talk about carbohydrates, or carbs as we like to call them, and dieting. There is always lots of discussion about low-carb or no-carb diets. Many of the most popularized diet fads have promoted low carb dieting. First let me tell you, that your body is designed to use carbs as the main energy source, not fat and certainly not protein. Medifast products take this into consideration. Carbohydrates are the most abundant biological molecules, and fill numerous roles in living things, such as the storage and transport of energy (starch, glycogen) and structural components (cellulose in plants, chitin in animals). Additionally, carbohydrates and their derivatives play major roles in the working process of the immune system, fertilization, pathogenesis, blood clotting, and development. Carbohydrates require less water to digest than proteins or fats and are the most common source of energy. Proteins and fat are vital building components for body tissue and cells, and thus it could be considered advisable not to deplete such resources by necessitating their use in energy production. Medifast prevents this depletion. Carbohydrates are not essential nutrients: the body can obtain all its energy from protein and fats, but the human brain cannot utilize fat energy. The brain can use glucose derived from the deamination of protein and this is what goes on if you do not get some carbs when you are losing weight. This is very bad because it depletes your lean muscle and makes it harder to stay thin once you are done dieting. Medifast helps prevent this by supplying you with adequate carbs and protein throughout the day. Carbohydrates, like proteins, contain 4 kilocalories per gram while fats contain 9 kilocalories and alcohol contains 7 kilocalories per gram. Medifast contains no alcohol products at all.
Foods that are high in carbohydrates: Breads, pastas, beans, potatoes, bran, rice and cereals. This distinction between "good carbs" and "bad carbs" is a large part of the low-carbohydrate diets, which in general promotes a reduction in the consumption of grains and starches in favor of vegetables, thereby reducing the high insulin levels that cause fat storage, and increasing the burning of body fat for energy through ketosis. Medifast products allow the body to go after fat stores for energy while providing the body with adequate carbs and sparing your lean muscle. Medifast is ideal.
