Have you ever wondered how celebrities keep so slim even as they advance in age? Three very well known celebrities have recently been speaking out about their methods to stay slim and healthy.

None of them have ever been on an extreme weight loss diet as health has always been their main concern. Lady Gaga is a very successful pop star that has had a string of #1 hits in the last couple years. She recently spoke out about her weight loss techniques to the London Telegraph. Lady Gaga was quoted as saying "I'm on a very strict healthy pop star diet. I don't eat bread, just vegetables and salad and fish. Eating like that is much better for me anyway but on Sundays I sometimes eat pasta." This seems to be a fairly common diet these days as bread is known to pack on the pounds fairly easily.

Jennifer Aniston has been very open with having to lose weight early in her career. One of her managers suggested she lose weight to try and attract acting roles. Jennifer had to research and learn how to lose the fat but through diet and exercise Aniston was able to drop 30 pounds and land the role on Friends that really launched her career. The diet Jennifer Aniston used and continues to use even today is called the zone diet. This diet consists of combining a ratio of carbohydrates, proteins and fat at every meal. Perhaps no celebrity has been as passionate about nutrition as Alicia Silverstone. She has recently published a book about her experience of becoming a Vegan. This involves cutting out meat and dairy from your diet completely.

Alicia is able to provide details on how you can still maintain a healthy nutritional diet without dairy or meats. This will help you lose weight without feeling fatigued or withdrawals. These three celebrities should be commended for their efforts to promote healthy weight loss.
