Lipids provide more energy per gram than carbohydrates (nine kilocalories per gram of lipids versus four kilocalories per gram of carbohydrates). High GI foods cause a greater blood glucose response than low GI foods. This just proves that high-fiber diets are effective for preventing diabetes mellitus and other pre-diabetic conditions as well! Nutrients that are needed in large amounts are called macronutrients. It has different length chains of glucose, more or less branched, and occurs in granules which size and shape vary between the plants that contain them. Glycogen and starch are complex carbohydrates.

The carbohydrate or protein in a food yields approximately 4 kilocalories per gram, whereas the triglycerides that compose the fat in a food yield 9 kilocalories per gram. In humans, the storage molecule of carbohydrates is called glycogen, and in plants, it is known as starch. Many minerals are critical for enzyme function, others are used to maintain fluid balance, build bone tissue, synthesize hormones, transmit nerve impulses, contract and relax muscles, and protect against harmful free radicals in the body that can cause health problems such as cancer. If not used directly, the body converts glucose to glycogen, a polysaccharide like starch, which is stored in the liver and the muscles as a readily available source of energy.
