Most United States and International Health organizations have a claim for proper weight management programs to advise exercise (increase calorie burning) with caloric restriction. There are also modified diet programs that support metabolic changes such as to consuming diets that are higher in protein. Protein takes more calories to digest and their biochemical pathways "cost" more energy to burn. A gram of protein costs 9 calories vs. 4 for the "cost" of burning carbohydrate. Diets that encourage "snacks" (healthy and mid calorie) also can contribute to more energy or calories burned in the digestive process. They can also contribute to less sugar spiking (keeping glucose in normal ranges) for brain and other organs. Clinical studies have also shown that calcium intake helps in weight loss, either from dairy or similar products and dietary supplements. K Lloyd M.S. B.S (Biochem, Health Sciences).
