Is there a way to prevent weight gain after a very low calorie diet?

Is there a way to prevent weight gain after a very low calorie diet?

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

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.

Is there any reason why I gain weight very easily now even on a low calorie diet as about 3 to 4 years ago I would eat more & not gain weight at all??

Don't starve urself: If u don't eat too often and wait too many hours to eat the body will store what it can into lipids=fat cells because it feels it should hibernate. If u eat every 2-3 hours the body feels it needs to burn off the food. Other aspects to consider are u'r thyroid, sex hormones like estrogen or Progesterone or even testosterone-but they would also come with unusual hair in areas u may not have had. ...Read more

Is if safe for obese-kids to have very low calorie diet?

Is if safe for obese-kids to have very low calorie diet?

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

Can a very low calorie diet allow you to maintain lean mass?

Can a very low calorie diet allow you to maintain lean mass?

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
