Workout and fat loss in diet

Work out is the most important way to keep the weight loss diet results for long. Researches show that a moderate work out is not significantly important for losing weight.But it is very important for keeping the same people from gaining all this weight back again.

A strenuous work out burns fat a long time after it is over, not only when it is actually done. In reality most people can not do a strenuous workout every day not even athletes .
It is better to begin with small to moderate workout a few times a week . Then gradually add more days and time, until one does it almost every day. Rest days are important too and can not be neglected .

This might sounds like a paradox :
1.The fact that a weight loss diet can be done effectively without any work out .
2.The fact that work out is necessary for weigh loss diet.
This work out necessity is in reality for keeping the results of the weight loss diet
These facts are rising lately from many researches but they do not contradict each other. While with dieting alone you can lose weight  keeping the results is another story .And here comes the necessity for physical exercise ,after the diet is over.

The importance of combining work out and diet is to get people used to doing work out so .
when they get to their ideal weight they will be already used to regular work out that will prevent them from gaining the weight back.
The truth is that a moderate work out burns more fat (55%) then carbohydrates(40%). Compared with a strenuous work out in which more carbohydrates (70%) are burnt then fat (15%)(numbers taken from a lecture on the subject). 
 If the time spent in the activity is the same ,than as the work out becomes more strenuous than its affect on weight loss is higher .This is because more calories are used and it is not important from what source.
At rest the body will do its own calculations .If you consumed less energy / calories then you spent then you will lose weight no matter what you burned at the time of the exercise.
