Detailed explanation-1: -How many calories are in one gram of fat, carbohydrate, or protein? Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

Detailed explanation-2: -Fat has more than twice as many calories per gram as carbohydrates and proteins. A gram of fat has about 9 calories, while a gram of carbohydrate or protein has about 4 calories. In other words, you could eat twice as much carbohydrates or proteins as fat for the same amount of calories.

Detailed explanation-3: -Calories in Carbs Although all carbs contain 4 calories per gram, they are not all created equal.

Detailed explanation-4: -The short answers are: All calories are the same by scientific definition, but they are not all the same as far as how your body responds to them. For weight loss, calories count but that doesn’t mean you have to count them. Your body reacts differently to various calorie-containing foods.
