"In general, muscle is not lost before fat—it is very dependent on nutrition and activity volume," Miranda-Comas says. "A person who is attempting to lose weight by not eating may lose weight in muscle first before fat."

The brain signals fat cells to release the energy packages, or fatty acid molecules, to the bloodstream. The muscles, lungs and heart pick up these fatty acids, break them apart, and use the energy stored in the bonds to execute their activities.

Fats. Fat has the most calories of all the nutrients: 9 calories per gram. In a healthy diet, about 30 percent of total daily calories should come from fat. This means eating about 50 to 80 grams of fat each day.

Excess fat can form on the body if you take in more calories than your body can use or burn off. Where your body stores this fat is determined in large part by genetics. Women tend to store extra fat in their hips, lower belly, and inner thighs.

Once frozen, the cells die. As the body begins to expel the cells naturally, you can begin seeing the results of the procedure. In most cases, you will see a reduction in fat within three weeks. In some cases, the final results won't appear until six months after the treatment.

Lipids, or fat, go undigested in your digestive tract until they reach your small intestine, where they meet bile. Bile contains bile salts, which act as an emulsifier of lipids. This breaks the large fat droplets into smaller droplets that are then easier for the fat-digesting enzyme pancreatic lipase to digest.

Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates. Because fats are such an efficient form of energy, the body stores any excess energy as fat.

Once fat cells form, they might shrink during weight loss, but they do not disappear, a fact that has derailed many a diet. Yale researchers in the March 2 issue of the journal Nature Cell Biology describe how — and just how quickly — those fat cells are created in the first place.

Unlike water-soluble vitamins, any excess of fat-soluble vitamins don't immediately leave the body. Instead, they're stored in the liver or fatty tissue for later use (2).

If you follow the atoms in 10 kilograms of fat as they are 'lost', 8.4 of those kilograms are exhaled as carbon dioxide through the lungs. The remaining 1.6 kilograms becomes water, which may be excreted in urine, faeces, sweat, breath, tears and other bodily fluids, the authors report.

Fat in the marrow of bones, in the heart, lungs, liver, spleen, kidneys, intestines, muscles, and lipid-rich tissues throughout the central nervous system is called essential fat, whereas fat that accumulates in adipose tissue is called storage fat. ... Lean body mass differs from fat-free mass.

The easiest macronutrient to burn is sugar. Exercise lasting from 10 seconds to several minutes uses predominantly glucose in the form of pyruvate, and if the exercise is intense enough, in the form of lactate. After several minutes of work, the body will begin to burn fats for energy use.

As a general rule of thumb, 10 per cent body fat is the safest place to be. You're lean enough to show muscle — including your six-pack — and you can see your veins from your shoulders to your hands, but you're not so shredded that you're becoming translucent.
