Body weight depends not only on the number of calories we intake, but also on certain chemical processes that occur inside our bodies.
There are number of factors that can affect weight gain or weight loss.
These are usually: physical activity, genetics, eating habits, and stress.
However, the most important role in this process belongs to the hormones that are responsible for metabolism regulation.
Glucose is the main source of energy for cells. After consuming food the blood glucose level increases . This is when the pancreas is supposed to release more insulin, a hormone that helps glucose to reach the cells.
Apart from giving energy, insulin also stores fat. If the level of insulin is high, your body will preserve fat.
Cortisol is a stress hormone.This hormone is produced from the adrenal glands, in order to prevent a decrease in the blood sugar level below the normal. This is the reason why when you are stressed, you tend to eat products that contain more sugar.
Cortisol slows down the metabolism in order to conserve more energy. If the level of cortisol increases, then your bowel will grow.
Leptin is the hormone of satiety. Leptin controls your metabolism and gives directions to the cells whether to preserve or burn fat. When the level of leptin is low, appetite increases and your body tends to preserve excess food like fat. Very often, the level of this hormone is reduced due to insufficient sleep.
Thyroid hormones (T1 and T4) produce the thyroid, and their main function is to induce lipolysis. They also play an important role in regulating metabolic processes. If you have low levels of thyroid hormones, it is very likely that your body weight will increase.
What and how should you eat to lose weight !?
According to some studies, in order to reach the desired weight, one should consume 3 meals a day.
Practicing strict diets is not at all healthy, and the result that is achieved is not long-lasting. Gradual weight loss is much better for the body and has longer lasting results.
If you want to lose weight, reduce the amount of calories you intake. For example, if your normal calories intake is about 1,900 calories per day, reduce it to about 1,700 calories.
Eat foods that are less likely to increase the level of insulin in your body.
Avoid foods rich in carbohydrates try eating high-protein foods instead. This it will help you feel full and will not cause overeating.
Proteins help form muscle mass and burn fat, even when you rest.
