Excessive calorie reduction, unexpected harm
Many people think that eating low in calories is a quick way to lose weight. However, Dr. Sarah Anzlovar, a nutritionist in the US, warned: A diet that is too low in calories can slow down your metabolism, causing your body to burn less energy even at rest. As a result, the body is tired, reduced performance, easily leading to muscle loss and increasing the risk of constipation.
In addition, a lack of energy also directly affects hormones. Studies on athletes show that long-term calorie restrictions reduce estrogen, testosterone, luteinizing hormone and increase cortisol, the stress hormone, inflammation and many other health problems.
Long-term consequences: from bones to fertility
Not only does it affect muscles and hormones, eating low in calories also leads to nutritional deficiencies, reduces bone density, increases the risk of hair loss and immunosuppression. The body will prioritize maintaining vital functions, while fertility will be limited. Women who overeat can limit calories and have their menstrual cycle, even reducing their ability to conceive," Dr. Anzlovar emphasized.
Excessive dieters are also susceptible to food obsession, cravings for sweets and carbohydrates, increasing the risk of binge eating. The phenomenon of gaining weight back after dieting is extremely common, creating a vicious cycle of weight loss, weight gain, causing stress and muscle loss.
Practice healthy: enough energy and balance
To lose weight safely, experts recommend determining the basal metabolic rate (BMR) to know the minimum amount of calories the body needs. Instead of cutting back too much, maintain a diet rich in protein, fat, vitamins, minerals, combined with reasonable exercise. Sustainable weight loss is not forcing the body to suffer from lack of energy. The important thing is to balance nutrition, exercise and listen to the body," Dr. Anzlovar emphasized.
