Yes it is with 9 kcalories per gram
Fat. Protein is the most satiating followed by carbohydrates and lastle Fat. This is because hih fat foods are flavorable, which stimulates apetite and entices a person to eat more.
An energy substrate is term that is generally used to describe macronutrients. The three macronutrients that give the body energy from calories are proteins, fats and carbohydrates. In terms of energy per gram it is fat that provides the most energy giving the body a total of 9 calories per gram whereas proteins and carbohydrate only offer 4 calories per gram.
Fat provides the longest term energy storage. This is because it is the most energy dense molecule in the body.
The most energy rich nutrient is fat. There are two other nutrients that produce energy for the body and they are protein and carbohydrates.
Protein and Fat
Fat is the richest source of all the macronutrients. One gram of fat contains 9 calories wheras the other macro nutrients like carbohydrates or protein give only 4 calories. So when fat is metabolized it gives in lot of energy.
Fats tend to be the most calorie dense and provide the most energy. For example, fats have 9 calories per gram whereas carbs and protein and 4-5 per gram. That's why we don't need large quantities of fat. It's calorie dense!
Carbohydrate Protein Fat
In animals the macronutrients are those foods which provide energy (carbohydrates, proteins, fats).In plants there are 3 classes of macronutrients which include structural, primary and secondary minerals. These are macronutrients because they are needed in large numbers (macro = large) to support the life processes of the animal or plant.
The rate of fat oxidation does not change when fat is eaten in excess
