First of all we should know what is Ideal body weight (IBW), it is a weight that is believed to be maximally healthful for a person, based chiefly on height but modified by factors such as gender, age, build, and degree of muscular development.
The right method to lose weight is to reduce slowly i.e. people who lose weight gradually and steadily (about 2 kg per month) are more successful at keeping weight off. Healthy weight loss isn't just about a “diet” or “program”. It's about an ongoing lifestyle that includes long-term changes in daily eating and exercise habits.
But at times, some people become very conscious about losing weight that they just try every method to lose weight without knowing the method is good or bad. Losing weight drastically is one of them.
In this, people try to reduce weight as maximum as possible in minimum duration of time so that they can achieve their ideal weight as soon as possible.
Negative impacts of losing weight drastically are:
- When you use a these diet or choose to lose weight any other way than with a healthy diet and exercise you are losing the wrong type of weight; water and muscle mass. This means that you are not losing fat at all and the potential to gain all this weight back is more than likely due to overall decreased metabolic effects.
- You are slowing down your metabolism by eating less and neglecting your body of calories, carbohydrates and fat because your body needs the correct types of these nutrients to function properly. When your metabolism slows down you are not only going to discover a decrease in the amount of weight you lose, but the capacity to gain it all back and then some is also increased.
- You find yourself in what is known as a yo-yo diet system where you are constantly losing weight quickly and gaining it all back. This can be dangerous for your health as well as your psychological emotions as well. It can be discouraging to find yourself in this cycle and even prevent you from trying to lose weight again.
- These types of weight loss programs are not for the long term. They utilize variations in starvation techniques that can only create problem in your weight loss goals in the future.
Other side effects of rapid weight loss include:
Headaches, Irritability, Fatigue, Dizziness, Constipation, Menstrual irregularities, Hair loss, Muscle loss, Dehydration, Malnutrition, Electrolyte imbalance, etc.
The only way to really lose weight and keep it off is by changing your lifestyle. Begin eating healthier and exercising regularly so it is part of your life, not a short term diet plan.
