The Biology Behind the Size of Your Behind

The new year always seems to bring the desire to "get in shape" - A poorly defined objective wave that can mean many things to many different people. But with obesity rates in the country more than 30%, it is reasonable to assume that fat loss is (or should be) a priority for many of us.

Unfortunately, it's not as easy as shopping and reality shows have you believe. This does not happen in a week, and no pill, cream or special exercise that you can do to speed up the process. Fat Loss through a very particular set of circumstances in your body - ie deprivation. The old "calories in calories / out" axiom is true, and there is no shortcut or roundabout way around.

Calories and Evolution

The word "calorie" was not created to make you feel guilty about eating. It's just a unit of measurement that defines the energy - it is true, every calorie is a small body energy package uses to run. When you give your body the right amount of energy to maintain their weight. When you get too much, gain weight - your body is a product of millennia of evolution, during most of which food was scarce. To avoid starvation when there was no food for a few days, your body accustomed to store calories as fat was developed. So when no energy gave it takes, you can draw on reserves rather than diminished organ function (not good).

If they were forced to live off their reserves for a prolonged period of time, which contract and got thinner. So if you want to lose weight, live right next to their fat reserves, right? Not so simple. Have fat reserves, so that the reduction of incoming calories to avoid restocking the same reservations that attempt to empty. But if you reduce too much, your body will fight - you see these fat reserves that the only thing between you and the slow death by starvation, so that gradually reduce the amount of energy needed to keep playing. It's just budgeting fat reserves, so we did not go through them too fast. If this continues for a long time, your body will start to break down muscle tissue for energy, keeping the fat reserves in place for when things get really tough.

Fat vs. Muscle

This is bad news because muscle tissue requires more energy to survive than fat. The fat just sits there, but the muscle tissue that works for you. It makes you stronger and less prone to injury, and keeps your body functioning at a higher level. It takes more calories to maintain a muscular body, so that in difficult times, your body will try to let go of the muscle before attacking the fat deposits. When this happens, your body needs to survive even fewer calories, so fat deposits are even less likely to be exploited.

The trick is simply to reduce the energy used in a small amount, while increasing power output. In other words, eat less, move more. Taking 500 calories less than your body needs each day in the results of a pound of fat loss per week. If you believe that the deficit only to reduce incoming calories, you risk muscle breakdown just mentioned. But if exercise is added, you work your muscles enough to keep them in good condition the growth cycle / constant and keep your body working at height. Your body will not reduce their caloric needs dramatically, because it has all this to maintain muscle tissue, making it more likely to tap into fat stores when power is low.


Your fat cells are like small bubbles filled with grease. The actual number of fat cells does not really change, they just get more or less complete as you gain or lose weight. When your body gets its fat for energy, deviates a little fat all the fat cells in the body. Over time, these cells are almost empty and you will be smaller.

This is also why point reduction does not work. The whole process is systemic, and there's nothing you can do (following liposuction) to get there in one place. Its largest part of the body will be the last to lose weight because it has only more stored fat to work through. But it will happen if you go with her, because biology said.
