According to many studies, we can lose weight if we burn more calories than we consume. Because doing so will create a calorie deficit, forcing our body to burn stored fat accumulated in the body. This leads to weight loss.
However, calorie deficit can be harmful if we do not follow healthy methods. The risks that the body may encounter include:
Malnutrition
If we don’t eat enough calories, chances are our bodies aren’t getting enough vitamins and minerals. Nutritional deficiencies can cause a long list of health complications. For example, if we don’t eat enough calcium-rich foods, our bone health is at risk.
Poor performance, fatigue
When we cut calories, our bodies try to conserve energy by slowing down our metabolism. This can leave us feeling cold and sluggish, leading to poor performance at work or exercise.
Effects on brain function
Like the rest of our body, our brains need calories for energy. Cutting calories too much can affect brain function.
Gallstones
Severe calorie restriction can lead to rapid weight loss, a risk factor for developing gallstones, which can cause pain.
Eating disorders
Eating disorders - a psychological illness, characterized by forcing oneself to eat or refusing to eat without regard to the body's natural needs, leading to harmful effects on physical and mental health. This can originate from dieting to reduce calories.
According to nutritionists, maintaining a reasonable calorie deficit will help us lose weight. But don't go overboard. Instead, aim for a reasonable deficit that allows our bodies to lose weight slowly but steadily.
