Spring has sprung and summer is almost here, which means that the teeny-weeny bikini sitting in the back of your closet once again is ready to make an appearance.
The question is, are you ready for its appearance?
For those fearing stepping out in swimwear, the allure of a quick fat-loss program or a celebrity diet can be too much to pass up. But the truth is that not all of them deliver the results they claim to.
Dr. Marc Lawrence, the self-proclaimed celebrity diet doctor, studied at Cornell Medical School and trained in emergency medicine at Stanford and general surgery at Harvard. On his Web site, celebritydietdoctor.com, he breaks down celebrity fad diets into fact and fiction.
"This is my way of reaching out to people," Lawrence told ABCNews.com. "A lot of people are interested in celebrities and their nutrition, so I take that and I add real nutrition advice to the celebrity plans."
Lawrence's main advice when it comes to dieting is to go fresh and natural.
"The way to get healthy and lose weight is to eat unprocessed foods," Lawrence said. "For example, take four ounces of corn straight from the cob. That is about 90 calories. Now mash them down into tortillas. Those are about 290 calories. Then dry those out and add sugar to make corn flakes, which are around 400 calories. Finally, press those out and add fats to get 600 calories worth of flavored corn chips. We have gone from 90 calories for four ounces of corn to 600 calories from 4 ounces of flavored corn chips.
"Everybody wants to be a part of the new diet craze," Lawrence added. "Everybody wants the secret, but the real secret is staring them in the face from the produce aisle."
Lawrence offered his opinions on today's newest, hippest celebrity diets:
In her new movie "Chloe," Amanda Seyfried is looking better than ever. She openly credits the raw food diet for her figure.
The diet consists of eating only unprocessed and uncooked foods. The proponents of this diet believe that when food is cooked, enzymes that aid in digestion are destroyed and the positive nutritional effects of the food can be lessened. The diet includes lots of fruits, veggies and nuts, but it also can include sushi or homemade cheeses and yogurts. If you can hand-make it from raw parts, you can eat it.
Seyfried admitted in the April issue of Esquire magazine that the diet is working to keep her slim. Whether or not she enjoys the diet is another story.
"It's intense. And sort of awful," Seyfriend told Esquire. "Yesterday for lunch? Spinach. Just spinach, spinach and some seeds."
But Seyfried suffers for her art.
"I have to stay in shape because I am an actress," Seyfried told Glamour magazine last month. "It's twisted, but I wouldn't get the roles otherwise."
In Lawrence's opinion, the raw foods diet is the best way to lose weight.
"Raw food is a great diet," Lawrence said. "If you are looking to lose weight, it is good to eat foods that are high in water content like vegetables. The raw food diet purports eating foods that are high in water, low in calories and high in nutrition. The reason we are fat is because we are eating processed foods, so a diet that says only eat unprocessed, natural foods is great."
Remember when Aniston appeared on the cover of GQ wearing nothing but a necktie -- at 40?
