Jennifer Aniston looked healthy and radiant at the premiere of “Just Go With It”. It looks like a pretty funny movie!
Jennifer keeps in shape by having three private yoga sessions per week. She also does cardio before and after her yoga sessions.

Cardio: In addition to thrice-weekly private yoga sessions, Jen also breaks a sweat during regular cardio routines. The treadmill and elliptical trainer are her two fitness machines of choice. She usually clocks about 20 minutes or more on one of these before her yoga session. Jen feels that the cardio not only boosts her metabolism, but it gives her muscles a warm-up before her yoga class. According to an interview with Self magazine, after a five-minute warm-up, Jen alternates one minute of high-intensity cardio with two minutes of recovery at a moderate pace. On high-energy days, Aniston will even follow up this interval training, which she does on the elliptical, with a 10- to 15-minute run on the treadmill at a 5.7-mph pace on a 1.5 incline.

As for her diet, she is said to follow the zone diet.

Well all of the celebs on here are being stalked by the paparazzi. I was just trying to give you a catchy headline! Jennifer Aniston was snapped arriving to the set of her new movie “The Baster”. I admire Jen for her fantastic body. I can only hope to be in such great shape when I’m her age!

This article is a bit dodgy, I found it on the net. It gives a bit of information about the diet Jennifer Aniston follows (The Zone Diet) and unfortunately I had to paste the whole thing in due to copyright restrictions. Anyway, enjoy!

How did Jennifer Aniston lose weight? This is a question which was pestering me for quite some time. I contacted a lot of people, read tons of celebrity magazines including the cheesy ones, and I searched through the internet endlessly. I was determined to find out the answer at any cost. After all, being a Jennifer Aniston fan, I was motivated to find out pretty much everything about her.

So, let us come back to the question again. How did Jennifer Aniston lose weight? Among the sources I tried to get information from, the internet was very, very reliable. I could easily find tons and tons of information about my favorite star without even breaking a sweat.

Today’s search engines are unbelievably vast and accurate and can give you lots information on pretty much any topic under the sun. Especially, if you are searching for information about a popular topic or a popular person, you are bound to get truckloads of information in literally a couple of seconds. In other words, the more popular your search term, the more details you will get.

Let’s now take a detailed look at the question ‘how did Jennifer Aniston lose weight’. One of the most important things that made Jennifer lose weight, apart from her physical workouts, is the diet she follows. She has changed her diet constantly and has tried different diets, but Zone Diet is one thing that became quickly popular after Jenny tried it once. The brainchild of Dr. Barry Sears, Zone Diet consists of eating healthy food in the following ratio – 40% carbohydrates, 30% fat, and 30% protein. The most important aspect of this diet is that the carbohydrates you get should be from low starch fruits and vegetables.

This way, you can burn your body fat very quickly and get back to figure in no time. Jenny tried this diet when she was a part of the hugely popular sitcom FRIENDS.

The Zone Diet, as expected, revved up Jennifer Aniston’s metabolism to a great extent and the result was evident in a few weeks. Her body was more flexible and the little puppy fat she used to have in her cheeks and hips was considerably reduced. Happy with the results, she continued with the diet and her workout plan for the next few months and achieved the perfect hourglass figure she was looking for. There you have it folks – that is the answer to the question ‘how did Jennifer Aniston lose weight” and possibly the secret of Jenny’s terrific figure as well.

In this months edition of Australias FAMOUS magazine they have a story called ‘Celebs True Weights Exposed’. Heres a little summary of what was apparently revealed. I’m sure these aaren’t the confirmed weights of the celebs, they are most likely estimates.
