When looking to lose weight, you've got two options: either you can expend more energy or take in less.
Many have tried to lose weight with the second route, only to find the pounds eventually creeping back.
Often people went back to their previous eating patterns and the weight returned, but it has been discovered by scientists that a reduced-energy weightloss plan can almost guarantee a return to blubberiness.
The scientists found that reduced eating would not only lead to a loss in fat, but a loss in muscle tissue as well.
As a result of the decline in muscle, the metabolic rate lowered, causing a decrease in daily energy expenditures. This makes it much easier to gain back the weight you lost.
A variety of scientific research then showed that this vicious cycle can be stopped by exercising, as this helps to maintain muscle mass. It is also possible that exercise raises metabolic rates in between workouts.
However, we are not positive that exercise will raise metabolic rates, nor have studies been able to consistantly prove that there is enough of an increase in metabolic rate to even make a difference in weight loss.
The influence on metabolic rate of different types of exercise is also unclear. For example , it is known that a long, intense run can significantly raise the metabolic rate in the hours between work-outs, but the effects of other sports such as weight lifting are unknown.
Now, it has been discovered by scientists at the University of Limburg in the Netherlands that by weight training you can actually increase the quantity of fat burned in your sleep!
