Not for young kids: Obese young children who are still growing in height can stay on a low (not extremely low) calorie balanced diet. They should lose enough weight to drop down from the "severely obese" BMI range, into the "obese" range. Then, they can take advantage of their height growth combined with moderate caloric restriction, to gradually drop into the "normal" BMI range over a 1-2 year period. Exercise too! ...Read more
Just out of curiosity is it possible to be on a very low calorie diet but not lose weight if consuming too much foods that cause bloating like sodium?
Bloating can be a: Sign of food allergies or gluten intolerance. Have yourself tested to make sure you know what you're allergic too. It's not the calories consumed, but the proportion of carbs to protein that will help you loose weight. Less than 1/2 cup of carbs is good with 2/3 of your plate with organic veges of 5 colors, and 4 oz of protein, lots of purified water after your meal. 1/4 cup fruit/day. Good luck! ...Read more
If moderate exercise: If one does some mild or moderate exercise, for 30-40 minutes, 3-4 times a week, she will likely stimulate his muscles enough to maintain them. On a "very low" calorie diet, she can get into trouble if the calories are too few (his body may break down muscle for fuel). Thus, "very low" calorie diets should be adjusted into "moderately low" calorie diets, which also have better long-term success. ...Read more
Yes: Weight gain can be prevented or overcome by a permanent change in lifestyle and in personal outlook. If a person eats fewer calories than he needs to live on each day, his body will use the stored fuel (fat). If a person exercises more than he did before, but does not start eating more calories, then his body will use up the fat (stored fuel). Easier said than done, but definitely possible to do. ...Read more

With intense exercise (cardio and weights) the weight loss can be more obviously. ...Read more
When you do a very low calorie diet you change your metabolism into a starvation mode.

Tissue breakdown: Very low calorie diets puts a person in ketosis. The body does not have the proper amounts of protein, carbohydrates and fat to carry out all the functions it has to do.

Will a week of refeed (eating about 3000 calorie aday) will reset metabolism after very low calorie diet?
Medically supervised very low calorie diet (800 calories). Ok to exercise. Principle of ketosis. Burn about 400 cal/day/hr monitor. Safe?
No safe shortcuts: This type of diet often makes the body angry, decreasing calories too much too quickly will send your body into starvation mode. Less calories = weight loss, but your body will become more efficient at holding onto calories, so you will gain the weight back and then some later on. Weight watchers is the safest and most consistent in my experience with thousands of people. ...Read more

Eating 3 meals and 2 snacks may show more results than calorie counting. Let me know how you do. ...Read more
