With everybody looking for the perfect body and health, it is easy to get lost in the craze. Most plans you will read will have exercise as part of the recipe to weight loss. If you hate the gym, you might be wondering if you really need it. And if yes, is going to the gym sufficient for optimum weight loss?
This has been for years a controversial topic with many experts coming up with different opinions on this matter. To fully comprehend the process of weight-loss, you must first understand the cell biology and how the body metabolism usually works in response to exercise.
You must also recognize what brings about the unwanted weight to devise ways of getting rid of it.
The cell mostly uses two main sources of fuel: fats and carbohydrates. The body prefers these two sources of energy over proteins. Carbohydrates are readily metabolized followed by fats in the body. There exist pathways that interconnect fats and carbohydrates (glucose) in the body.
Excess glucose in the body can be converted to fat; this happens by first breaking down glucose into acetylCoA. Because the glucose is in excess, the body would redirect the AcetylCoA from entering the TCA cycle and producing more ATPs (energy molecules in the body).
It will be then used as building blocks of fatty acids which are then stored in fat cells(adipocytes) in the body. In the absence of enough glucose supply, fats are broken down to produce energy for the cells.
What is the relationship?
During exercise cells become overworked and the metabolism of the body generally increases. This then depletes the glucose stores in the body forcing the cells to find alternate sources of energy. Since fats are second in line in the metabolic pathway as a source of fuel, they become metabolized to produce energy in a process called lipolysis. What this process does is reverse the mechanism of fatty acid formation. AcetylCoA is generated and then enters the TCA cycle to produce ATPs.
The main reason why there have been arguments about the feasibility of exercise as a means of weight loss is that it depends partially on dieting. Exercise alone will hardly make one lose weight if not coupled with correct dieting.
The diet to be adopted should be able to push the body into using up its fat stores as a source of energy. This can only be achieved by minimizing the intake of carbohydrates. Low carbohydrates in the body will lead to a low supply of glucose to the cells which will necessitate the use of the fat stores in the body as a source of cell energy.
Scientifically exercise is an excellent means of weight loss that has been proven not only to be effective in weight reduction but also general health improvement. Its success, however, depends on dieting.
Low carbohydrate and high protein diet will go a long way in ensuring you lose weight and equally stay healthy. Remember, when it comes to weight loss, calories are the universal currency. You are either adding or subtracting the right amount.
