Hi everyone. I have a question that might seem silly - over the years, with various diets and regimes, I have been warned about not letting calories get too low or the body goes into starvation mode. It seems most people are on between 700 and 900 calories, which is below what is advised - is that why there is a need to supplement vitamins and calcium? With people being so successful with weight loss , it doesn't seem to be hurting the metabolism...so is that just general advice but the fact that sleevers do it under medical supervision makes it different?
Reference Guide for Calories
"You can actually hurt your body's ability to lose weight by going too low. Here's why. The body has a protective mechanism. When calories drop too low (we recommend a minimum of 1,200 for women and 1,500 for men) the body reacts as if it is starving and tries to conserve energy. It will lower your metabolism, conserve calories and fat, and you will not burn calories as quickly. This results in a slower weight loss or even no weight loss. This is what's know as "Starvation Mode."
When calorie intake falls below 1,200 to 1,500 calories a day, it is also extremely difficult to follow a balanced diet and obtain all the nutrients that are needed by the body to stay strong and energetic and prevent disease. These very low calorie intakes can also lead to other health problems such as eating disorders, gout, gallstones, and heart complications. For these reasons, the SparkDiet strongly suggests not going below 1,200 calories daily for women and 1,500 calories daily for men."
