Fat. Ounce per ounce, fats provide roughly twice the KCals of carbohydrates, and lots more than proteins. [[User:Cjonb|Cjonb]] 20:03, 2 Jun 2008 (UTC)
Lipids provide the most amount of energy per gram compared to carbohydrates and proteins. They contain twice as many calories per gram (9 kcal/g) as carbohydrates and proteins (4 kcal/g).
Lipids store more energy per gram than carbohydrates or proteins.
Fats (lipids) contain the most energy per gram compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 calories per gram, fats provide 9 calories per gram. So, gram for gram, fats contain more than twice the energy of proteins and carbohydrates.
Lipids have 9kcal/gram while carbs have 4kcal/gram
Lipids contain the greatest amount of chemical energy compared to carbohydrates and proteins. Per gram, lipids contain 9 calories, whereas carbohydrates and proteins contain 4 calories per gram.
Gram for gram, fats store the most amount of energy in the body, approximately double the amount of energy carbohydrates store.
Fats have the most energy gram for gram. I think that lard (sometimes called shortening) is the highest calorie out of all fats (but it's not much different to all other fats really).
Fats generally supply the most energy per gram in our diet. They provide 9 calories per gram, while carbohydrates and proteins provide 4 calories per gram. In your lunch, foods high in fats such as nuts, seeds, avocado, or fatty fish would supply the most energy per gram.
Hydrocarbons like gasoline or diesel generally provide the most energy when one gram is burnt, as they have high energy densities. Other fuels like hydrogen gas or methane can also provide a lot of energy per gram when burned.
Bread
The primary nutrients that yield energy are carbohydrates, proteins, and fats. Carbohydrates provide approximately 4 calories per gram, while proteins also yield about 4 calories per gram. Fats are the most energy-dense, delivering around 9 calories per gram. Alcohol can also provide energy, yielding about 7 calories per gram.
Pure hydrogen gas gives off the most energy when burned, producing about 142 kilojoules per gram.

Lipids provide the most amount of energy per gram compared to carbohydrates and proteins. They contain twice as many calories per gram (9 kcal/g) as carbohydrates and proteins (4 kcal/g).

Fat: 1 gram = 9 calories Protein: 1 gram = 4 calories Carbohydrates: 1 gram = 4 calories Alcohol: 1 gram = 7 calories as far as energy density, fats have more calories. fat and protein are very slowly digested so not a good source of quick energy. foods like grains and pasta are good for quick energy.
