Any physician out there that can tell me how fat leaves the body when you are dieting?

Answer 1

a biological process called lipolysis converts stored lipids in fat cells to the cellular energy source called ATP. ATP is the primary energy source used for all anabolic and catabolic functions in the muscle cells and is used for all muscular contractions. the body will only convert so much free fatty acids into ATP in a 24 hr period and ATP stores never go below 60%. scientists still don't know why ATP stores do not decrease lower than 60% regardless of the caloric intake or amount of exercise that is performed. this is why healthy fat loss is a slow process. once the body has utilized all energy that it will from fatty acids and ATP it will utilize more fuel from glycogen which is stored in muscle cells and in the liver and catabolize amino acids from muscle proteins. this is why people that starve themselves lose more muscle than fat

Answer 2

Hey, I'm not a physician either but I have a lot of experience with people going on diets. When you constantly eat your body uses the calories from that food to make energy. When your on a diet your calorie intake of course decreases causing your body to use that stored fat as energy instead. Calories are being burned every second of the day but if you burn more than you take in you begin to lose weight from the fat you had being turned to energy. Fat does not shrink or expand it can be lost without liposuction lol. Hope I could help.

Answer 3

Fat doesn't actually 'leave' your body when you diet. That is, you have fat cells under your skin all over. Those cells are in thin layers on your scalp, and thicker layers in other areas. When you get 'fat' or gain weight, each cell plumps up. You don't actually create or lose fat cells, just plump or deflate them.

Dieting (and dehydration) use the energy in those cells, flattenining them like balloons. When your body has extra energy (calories) to store, it stashes it in those cells, plumping them back up.

Liposuction vacuums the cells out of your body, which is why it is considered a more permanent solution.

Answer 4

I am not a doctor,however I do know that your body begins to use the stored fat as energy.

Answer 5

See below for article on fat metabolism.

Answer 6

It doesn't leave. Fat cells shrink or expand, but they never go away, unless you have liposuction surgery.
