How do hormones affect weight? 

THERE ARE 4 MAIN HORMONES AFFECTING WEIGHT:

1. Cortisol (stress hormone):

In the premenopausal/pre-menarche stage, symptoms such as hot flashes, insomnia, decreased sexual function,... cause discomfort, frustration leading to high stress hormones. This increases the feeling of hunger, especially for foods containing sugar and many starches, leading to uncontrollable weight gain.

2. Reproductive hormones (estrogen, testosterone, progesterone):

When entering the premenopausal/pre-menarche stage, reproductive hormones tend to decrease over time. Low estrogen levels reduce the metabolic rate, as well as make the body use starch and blood sugar less efficiently, leading to more fat storage. Moreover, the decrease in testosterone also breaks down muscle blocks, the fat burning process becomes slower making it very difficult to lose weight.

3. Thyroid hormones:

If you have a scientific diet and regular exercise but still cannot lose weight, the cause may be that you are having hypothyroidism. Decreased thyroid function (hypothyroidism) makes the body's metabolic process worse, leading to a low ability to burn calories even though you exercise very strictly, as a result, you continue to gain weight and almost cannot lose fat.

4. Insulin hormone:

Insulin is imbalanced from the age of 40 onwards. Excess insulin will disable leptin hormone making you feel hungry even when full. In addition, too high insulin will inhibit the fat-burning process and increase blood sugar levels causing weight gain and obesity.
