Exercise, Metabolic Rate and Food

The human body is mathematical in how it makes decisions. It has tolerances for the way your body functions and if something goes beyond that tolerance, the reactions are driven by an algorithm which decides what adjustments to make. Temperature is too high; please start to sweat. Temperature too low; please start to shiver. In addition, the human body is designed for efficiency and survival. Therefore, in a perfect world, you should be able to run a marathon on nothing more than a couple of bananas. If you weren’t able to, imagine your plight on the savannah’s of Africa, trying to find food. Both these factors go into play when you are trying to lose weight.

If you wish to lose a pound of weight, you need to eat approximately 3500 calories less food per week or 500 calories per day. What ever you are eating, if you eat 500 calories less, you will lose weight, at least temporarily. This is why crash diet’s work. Once you stop, you will go back to your original weight or worse add some more. This happens as your body realizes that something is amiss and the food is less available. It, therefore, slows down your metabolic rate to compensate. When your crash diet is over, the slower metabolism is working against you. You will quickly put on weight as a couple of chocolates can end up being about 500 calories.

This is the reason it is easier to never have put on weight in the first place. To lose weight long term requires a change in lifestyle and the ability to understand how your body is designed. In simple terms, it requires an understanding of your diet and ensuring that you get all your nutrients from quality food while watching the quantities and composition. Adequate sleep and a good diet combined with some form of exercise which increases your metabolism is your best bet to long term weight loss.
