Yes it’s entirely true. And it is not good at all for your health, even if you believe the sport is generally healthy.
Why is that?
First, every woman has sexual hormones (estrogens and progesterone) and a small percentage of testosterone, produced in ovaries and adrenal glands. All these hormones have a different chemical structure, but all of them share the same molecule at start, the cholesterol molecule.
It is no news that cholesterol in our body exist in two forms: circulating in blood, and in fat deposits everywhere in the body. This is the reason why, we go to gym, to burn that stored fat, as soon as possible.
When we begin our workout, generally, we will increase every day the level of our effort, the time we spend at the gym, and when we enter in routine, we try other machines, maybe other sports. We can say the beginnings are hard on every sport; everything will become possible in the middle and sometimes become obsessive in the end, especially if your workout had no results as far.
All efforts you do in order to slim, you will lose some fat on the beginning, you will have a period when your weight will stagnate, and after that if you perseverate, you will slim enough to be happy about it.
In the slimming process, we do a lot of sport and paradoxically we don’t eat so much. This way, we will develop a big imbalance in our body between demand and offer. Because of this imbalance, our metabolic rate will increase and that’s how we lose weight.
Everything seems to be alright until the fat stored in our body, decrease under 16%.
Under 16 % fat in our body, there is not enough fat to produce sexual hormones, that’s why in the absence of these hormones, women stop menstruate. Our body prefer to keep the remaining fat to produce energy for the body, producing heat.
It is like the body, stop the functions which are not important, keeping active the surviving functions. And how relieved we feel, when we see our body is really set for survival.
By contrary, when a female body stops menstruating, a lot of problems appear.
One of them is, they can suffer a lot of fractures, because in the absence of sex hormones, the bone density decreases and the bones become very fragile at minimum impact. Other facts are: women cannot procreate in this period of time and others become anorexic, could develop hot flushes and some become emotionally unstable.
In conclusion, it’s very important , to continue to eat a healthy diet, not to decrease under 1200 calories/day , having a very realistic workout not exceeding 1 hour and 20 minutes /day and not to forget the multivitamins and multimineral supplements .
