Dr. Oz Discusses the Total 10 Rapid Weight-Loss Plan

Rapid weight loss -

Behaviors like these can help you keep weight off long-term 18 , 19 , 20 , However, several studies have found that rapid weight loss may be just as effective as slow weight loss, even for the long term 4 , 5. In one study, people followed a rapid weight loss diet for 12 weeks, while 97 people followed a slow but steady weight loss diet for 36 weeks.

This means that both diets were equally effective in the end People in the rapid weight loss groups had support from doctors and dietitians during the weight loss and weight maintenance phases.

Research shows that having support from a health professional can improve your chances of long-term weight loss success 23 , Also, doctors and dietitians try to minimize the health risks that come with eating very few calories. These risks include muscle loss, nutritional deficiencies and gallstones.

Diets that promote rapid weight loss are often very low in calories and nutrients. This may put you at risk of many health problems, especially if you follow a rapid weight loss diet for many weeks.

Losing weight is not always the same as losing fat. While a very low-calorie diet may help you lose weight fast, a lot of the weight you lose may come from muscle and water 4 , In one study, researchers put 25 people on a very low-calorie diet of calories per day for 5 weeks.

They also put 22 people on a low-calorie diet of 1, calories per day for 12 weeks. After the study, the researchers found that both groups had lost similar amounts of weight. However, the people who followed the very low-calorie diet lost over six times as much muscle as those on the low-calorie diet 4.

Your metabolism determines how many calories you burn each day. A slower metabolism means you burn fewer calories per day Two reasons why the metabolism drops on a very low-calorie diet are a loss of muscle and a fall in hormones that regulate your metabolism, such as thyroid hormone 27 , Unfortunately, this drop in metabolism may last long after you finish dieting 6.

These foods contain fewer calories per gram and are also quite filling, which may help you lose weight Gallstones are hardened pieces of material that form inside the gallbladder.

They can be a painful side effect of losing weight too fast 8 , 38 , Normally, your gallbladder releases digestive juices to break down fatty food so it can be digested. Gallstones can form when substances inside the digestive juices sit for a while and have time to join together.

The gallstones can become stuck inside the opening of the gallbladder and cause a gallstone attack. This may cause severe pain and indigestion Summary: Losing weight too fast comes with many health risks.
