Weight loss takes place when the body cells burn more calories than what is consumed with food intake. This usually happens when you do exercises or when you are on a diet. The activities you do such as jogging, weight lifting, and even walking will increase the metabolism. This is what leads to weight loss. The body is composed of fats, proteins-muscles, bones, flesh, skin, body organs. It also contains fluids such as blood, mucus and water. When an ordinate person loses weight, it is most likely that they will think that they have lost fat content. Scientifically, when a person loses weight, it does not necessarily mean that they have lost fats, it could be muscle mass or even fluids.
Most people who are overweight and start a weight loss program usually lose the most weight in the first few days of the program. This happen because the person has lost water weight. After this you are more likely to gain weight in a short period of time because you are hydrated and the water is back in the body. As time goes on, you find that they will have a difficult time losing the rest of the fats.
Weight loss scientists would say that the ratio of the body components has changed. A great reduction of any of the components of the body will affect the overall weight of the person. There are circumstances where a person loses too much body fluid and it leads to weight loss. They usually get a serious case of diarrhea that will cause dehydration. Diarrhea always dehydrates the body so you will have to continue drinking water to replace what was lost.
The more you weigh the more likely it is that you have water weight. The main cause of weight fluctuation is due to water retention. Our bodies tend to retain water when we eat sugary, processed and high calorie foods. Foods that are rich in sodium are the main cause of weight gain due to water retention in the body. This is the reason we are discouraged from taking in lots of foods that are prepared because they contain lots of salt. Salt contains sodium and that is the main culprit behind the body's water retention.
It is hard to say that you should avoid eating salt completely because all foods contain some traces of sodium though in different amounts. Bananas have potassium that aid in preventing water retention. Gaining weight is caused by accumulation of fats in your body as well as retention of water. When you reduce the caloric intake, your body will lose a lot of water which will result in weight loss. The body then turns to the stored fats and proteins which make up the muscles in the body to get the needed water. At this point you will also lose a lot of water because the muscles contain a lot of water. This will make you thirsty. They you will drink water which will hydrate the body and you will gain your lost weight back.
