"Lose ten pounds in a week - but 10 pounds of what ?
For moderately obese people, there are only physically possible, a maximum of 2 pounds (about 1 kg) of fat to lose in a week, even in very difficult conditions remain energy restriction fat loss is slow. A pound of fat is 1000 calories per day for a week, enough for someone to survive even under conditions of starvation. When losing weight, only a desirable reduction of fat should be. Losing weight too fast is the increased loss of lean tissue such as muscle, in a reaction to the perceived cause of famine (reduction of lean body mass is the most effective way to reduce BM and save calories ).
When on a crash diet (anything that reduces the calories by more than 20% of normal caloric intake) the body will begin to maintain fat reserves instead of burning glycogen and muscle. The water is removed from glycogen in the urine locked and can be used up to 1 liter per day (kg), which represents a loss of short-term rapid weight, strengthening the belief that crash diets of how to lose weight. But your fat reserves are still in tact.
A working muscle is the unit requiring more energy in the body, reduces muscle mass is a good idea for the body as it tries to avoid starvation in the famine. However, the loss of muscle mass is definitely a bad idea for those who lose fat and difficult to plan a mass lead to saprogenic (loss of muscle mass). While crash diets is estimated that for every pound of fat lost, there could be a similar loss of lean tissue to be. In times of potential starvation, the body will also slow down your metabolism in order to avoid hunger, reducing impolitic enzymes burn fat and increases saprogenic enzymes slow down to conserve fat reserves. This leads to a loss of lean body mass and cause a further reduction in the basal metabolic rate. In other words, the organization has successfully put the new low energy available and can now survive with less food than he had before, so they get all the other fat stores, and even more potential famine.
If the system inevitably comes to an end and the diet starts eating normally, your calorie needs are now less than before, and return to previous eating habits had a greater excess energy available before the regime began created. Due to restrictive diets, there is also a phenomenon known as binge eating (RUBE) rebound syndrome, which is to return to the weight at which it was used is the attempt of the known organization. This is probably driven by adjoins and other bioactive signaling molecules of fat cells in their attempt to return to normal size product. In EBITDA as its name suggests, an inexplicable and uncontrollable urge to overeat on bulimia often at a loss of control around food and then. After crash diets, weight often degenerates about starting the diet often results in a lower proportion of fat, but eventually lean muscle mass (in weeks) back.
For the reasons mentioned weight rebound is a common feature of crash diets. This could also be the beginning of the cycle, is symptomatic of harmful accident or you-you dieting. This is where the idea that "diet makes you fat" is clear and this position has some validity. The scientific community refer to it as adiposity rebound.
Therefore, the message from this is for those who lose weight, is very simple:
Do not crash diet wants calories to no more than 500 calories estimated to reduce your daily caloric needs
Continue to exercise and to promote moderate weight training to anyone saprogenic
Eat healthy and maintain a healthy weight by eating to satiety plant fiber and whole foods
