when they say fat yields this much energy or carbs give that much energy they are talking about calories. and more specifically they are talking about Kilocalories. 1 Kilocalorie is the amount of heat it takes to increase the temperature of 1 kilogram of water 1 degree (i believe fahrenheit) at one atmosphere (basically means sea level ish). heat is the energy.
carbohydrates yield 4 calories/gram
proteins yield 4 calories/gram
fats yield 11 calories/gram
alcohol is 9 calories/gram (just threw that one in there) ^^
If you mean why: because it is a much more efficient way to store energy than, say, a carbohydrate. You would need twice the amount of carbohydrate molecules to give the same amount of energy.
No, body fat doesn't give them energy
Well, 1g of carbs or proteins provides 4 calories of energy. The only other source of energy are alcohol and fat. Alcohol provides 7 calories of energy per gram and fat provides 9 calories of energy per gram. So if you want over twice the amount, then the only option is fat.
fat. that is why fat people are so athletic, and smarter than everyone else. they store all that energy in their body and that is why they are power athletes. cuz they release all that double energy and boom its on!
Yes. Carbohydrates give you energy. But if you eat a lot of carbohydrates and dont work out, this energy will be turned into fat. Fat isn't bad for humans either, because it works as an energy store for later, but too much fat is not healthy.
fat helps your body stay warm and give you energy
Sugar is a source of energy, but mostly fat is, because, when you're fat, you're simply just storing energy...
That sounds like fat - fat has a high energy concentration. I am not sure whether it is more than twice, though.
To give your cells energy
t5s are a fat burner they give you energy to train for longer but the answer is yes most people take them for the gym to lose body fat and get into shape
