What is Diennet Diet?

Firstly, the Diennet Diet is more than an eating plan, it’s a lifestyle change. The “ingredients” include custom meal plans and herbal supplements. You’ll follow the program based on the answers of your initial questionnaire. Both women and men of all body types can use it.

We’ve found before and after photos, as well as dieter testimonials. Will it work for you? Read on…

Cost of Diennet Diet is Worth the Expense

The first issue tackled was the price of the Diennet Diet. “The cost of some of the treatments is $180 for a three-month supply,” said our Research Editor. “When you break it down, that’s $60 per month.”

“I paid $590…eat a very healthy low fat diet and I exercise! I stopped drinking alcohol and increased my exercise,” said one patient.

When dieters mention the price, we look to see if they also highlight the benefits.

“It works very well. It’s cost is high but very worth your money,” stated a dieter.

“I can afford to buy the pills,”” commented another.

Seeing Results From the Meal Plan

Based on user testimonials and reviews of the Diennet Diet, patients see results. One person commented, “I wanted to loose 20 pounds after my pregnancy and I did…was easy.”

“Started Diennet weight loss program last year…just reordered last week for maintenance. I think this program is the best,” commented another.

More dieters continued to praise the Diennet Treatment.

“Less of a diet and more of a lifestyle plan…you don’t feel like you’re on restriction therefore you’re less likely to cheat. Plenty of fruits, vegeatables and proteins to choose from and snacking between meals makes this diet ideal,” said a dieter.

“I don’t feel hungry since there are 3 meals and 3 snacks on a daily basis. It’s working for me so far,” mentioned another.

Our research connects solid results with long-term success. There’s a benefit when dieters see solid results while following the Diennet Treatment.

The Science Supporting the Program

There’s a critical part of the review process, and it’s research. Are there published studies on the official website? No, but let’s look at the approach used by the Diennet Treatment. You’ll complete a health assessment and from there you’ll receive a custom meal plan and supplement. Since it’s tailored to you, it’s impossible to have a studies showing the effectiveness of a custom product. Looking at the ingredients in Diennet pills, there’s 42 ingredients approved and inspected by the DEA, FDA and Board of Pharmacy. Also, there a wealth of research showing custom meal plans help dieters lose weight, when they follow their plan.

Can you benefit from the Diennet Diet? Based on user testimonials and positive feedback, there’s a chance. We like that Diennet spent nearly 40 years researching malnutrition and translated his studies into the Diennet Treatment.

What You Should Know About Diennet Diet

The Diennet Diet, a program founded by Dr. Marcel Diennet, began in 1996 and launched online. This doctor's first practice actually began in 1973 (Paris, France), and he established the Diennet Institute in Beverly Hills in 1981. This online method is a weight loss program for virtually anyone. The Diennet Diet is designed specifically to suit you as an individual. A questionnaire is filled out and you are given a personalized diet plan (can last for a minimum of three months).

When you become a member of this online diet program, you receive a weight tracking diary to note your progress, a database of diet recipes, before and after photos to track your progress, order streamlining, regular access to a medical expert, and a weekly diet menu sent to you by email. The Diennet Diet doesn't merely address weight reduction or fat loss as a whole, but rather focuses on specific conditions like cellulite. Other conditions that are addressed on the Diennet Diet website are PMS and Menopause. New patients must provide a "valid doctor exam" and a "valid blood test." There is a link on the website discussing common over-the-counter diet supplements, and how they may not work at all. However, there does appear to be a supplement formula incorporated into the Diennet Diet program to potentially assist with weight loss.
