What happens when we eat too much?

If we eat more than what we really need, or body converts the excess food into fat and we become bulky and heavy. The skeleton and the joints are not designed to carry too much continuous load; hence, at some point of time the back and the joints begin to ache. Any kind of fast movement becomes tiring and strenuous for the heart and the circulatory system. We get out of breath very easily. Fat people are often the butt of people's jokes. Although is is difficult for them, they can get in shape again though training and healthy eating.
