Detailed explanation-1: -Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

Detailed explanation-2: -A gram of protein is always four calories, but you will have to use energy to digest it. The energy needed to digest protein is 0.8-1.2 calories per gram, leaving you effectively with 2.8-3.2 surplus calories per gram of protein. Pure amino acids are “pre-digested” and should thus be quite close to 4 calories per gram.

Detailed explanation-3: -1 egg white can provide 4 grams of protein, with only trace amounts of fat and carbohydrates which aren’t enough to be concerned with. Pure Whey Protein Powder: In a pinch this can be a savior so it’s great to have on hand.

Detailed explanation-4: -General recommendations are to consume 15–30 grams of protein at each meal. Studies show higher intakes-those more than 40 grams-in one sitting are no more beneficial than the recommended 15–30 grams at one time. Don’t waste your money on excessive amounts.

Detailed explanation-5: -Since protein provides 4 calories per gram, if your goal is to consume 20 percent of your calories from protein you’d need to eat 400 calories, or about 100 grams, of protein per day when consuming a 2, 000-calorie diet.
