The 7 Hottest Celebrity Diet Plans

THE 5-FACTOR DIET

WHAT IT IS: Created by celebrity trainer and fitness guru Harley Pasternak, the “five” in the 5 Factor Diet comes from the number of elements each meal should include – protein, complex carbs, fiber, fat and fluids. Followers eat five meals a day with recipes that contain no more than five ingredients. One cheat day is allowed per week where you can eat anything – and everything – you like, guilt free.

THE FRESH DIET

WHAT IT IS: The Fresh Diet delivers gourmet chef-prepared meals directly to your doorstep. Supposedly, it tastes so good you don’t even know you’re on a diet. Meals are customized according to your weight loss goals, exercise amount, food likes and dislikes, and also offers gluten-free and vegetarian options.

THE ZONE DIET

WHAT IT IS: Developed by former scientist Dr. Barry Sears, The Zone Diet involves getting 40 percent of your daily total caloric intake from carbohydrates, 30 percent from carbs and 30 percent from fats. According to Sears, balancing the correct amount of amino acids with carbs helps control the appetite to prevent over-eating (which leads to weight gain). Followers eat three portion-controlled meals and two snacks a day, preventing you from getting too hungry – or cranky. Hollywood hottie Jennifer Aniston was such a big fan, some have even called it the “Jennifer Aniston Diet."

PRESSED JUICERY

WHAT IT IS: Hollywood seems to be juiced over this six-juices-a-day, 1,200-calorie intense cleanse. While on the Pressed Juicery diet (said to be a major bloat beater), followers receive a daily supply of juices specially delivered every morning. Each fresh, nutrient-packed drink is designed to replace meals and snacks, and all alcohol, caffeine, and nicotine should be avoided.

“I drink these between meals to be sure I’m getting everything I need,” says Nicole Richie. “I don’t go a day without a Greens Juice – kale, spinach, celery, cucumber and romaine. It’s actually really good!”

“The food is good and I don’t have to think about it!” says sultry star Sofia Vergara. But the best part? You’ll even get dessert.

SUNFARE

WHAT IT IS: One thing’s for sure – Hollywood loves convenience. Sunfare, another diet plan delivered straight to your doorstep, offers three personalized meals and two snacks. Tailored to your tastes and goals, there’s no menu planning, shopping or cooking involved – Amen to cutting out the guesswork!

“When I want to kick it up a notch, I get Sunfare meals delivered,” says Audrina Patridge. “I eat 1,100 to 1,200 calories per day, mainly lean protein, lots of green leafy veggies and low carbs.”

CELEB FOLLOWERS: Audrina Patridge, Eva Longoria, Britney Spears, Garcelle Beauvais, Kim Kardashian.

THE SOUTH BEACH DIET

WHAT IT IS: According to their website, The South Beach Diet is “a food-lover’s diet”. Divided into three phases (the first two are the most strict), the program is said to eliminate cravings, kick start weight loss and maintain for life. While there’s no counting calories or strict portion sizes, followers must say goodbye to bread, rice, potatoes, pasta, baked goods, and fruit – at least for the first two weeks. Relatively simple in principle, it replaces “bad carbs” and “bad fats” with “good carbs” and “good fats."
