3 Week Diet Review - 6 Things You Need to Know


If you haven’t looked carefully at The 3 Week Diet, now’s your chance. Here at DietSpotlight we dug deep and created a comprehensive review, examining the ingredients, side effects, customer service and scientific research. Furthermore, we focused on dozens of user comments from all over the internet. Lastly, we compacted all of the facts and feedback to give you the information you need.

What is the 3 Week Diet?

First off, the 3 Week Diet plan claims to help you drop 12-23 pounds in only 21 days. This program is suitable for women and men of all ages, and it was created by Brian Flatt, a personal trainer, and nutritionist. According to Flatt, this is the fastest diet on the market today. To get started, you simply download the eBook from the website, which costs $47. A specific eating plan and some exercise are required. However, all of the foods involved are readily available in local grocery stores. [1]

We are uncertain when The 3 Week Diet first emerged. This weight-loss program is backed by a 60-day satisfaction guarantee, and there are some customer testimonials presented on the official website, but read on…

Unrealistic Weight-Loss Claims – “A Concern?”

The first issue we found with the 3 Week Diet was the fact that weight-loss claims may be a little over the top. According to our Research Editor, “This system promises 23 pounds of weight-loss in only 21 days, which is very extreme. This means you will drop more than a pound a day, which is not very likely.”

“Did not drop 23 pounds! This diet is unrealistic because you can gain the weight you lose right back. It’s a fad diet! ” stated one person. [2]

Another customer commented, “It’s not healthy to lose this much weight in only three weeks.”

3 Week Diet Complaints – “Another Drawback”

We found some discouraging dieter comments posted on the web regarding The 3 Week Diet meal plan. One individual stated, “Not worth the $47. I wish I had saved my money.”

“Didn’t do what I wanted. On to the next diet program,” said another person.

According to our research, if there is a certain part of a diet program or weight-loss system that is especially bothersome (unrealistic weight-loss claims, too many dieter complaints, bad taste) the chances of prolonged success are not good. So, if The 3 Week Diet does cause a high number of dieter complaints, this could be a major dilemma. [3]

The Science – “Is There Any?”

Sadly the official website for The 3 Week Diet does not present any solid science to support this weight-loss method. Naturally, this is discouraging; especially for us at DietSpotlight because we need to see some documented clinical research that supports the program. [4]

What Users Are Saying

"”Love it! Totally doable diet! Here goes losing at least 10 pounds and feeling better after I eat! So excited.”"

"”I don’t lose as fast as I want to. However, I have lost a lot of weight.”"

"”Editor!!!! This book is somewhat repetitive and not too well written. The advice was OK but no revelation or insights that aren’t in hundreds of other diet books.”"

The Bottom Line – Does the 3 Week Diet Work?

Now the moment you’ve been waiting for: our bottom line on The 3 Week Diet. First off, we like that this diet is backed by a 60-day satisfaction guarantee and there are some dieter testimonials posted on the official website. However, we have some reservations about it because it’s not backed by any actual science. Also, we’re concerned about the unrealistic weight-loss claims, as well as the customer complaints we found posted on the web. [5]

If you’d like to drop more weight, then we advise you to go with a diet plan or supplement that is backed by solid science, gives you plenty of bang for your buck and does not make unrealistic weight-loss claims.

Among the best products we’ve seen this year is one called Dietspotlight Burn. Its formula is a unique combination of four ingredients, which have been proven in documented clinical research to help elevate metabolism and enhance fat loss. Also, we have not found any talk of unpleasant side effects and comments on the internet indicate people see solid results.

The makers of Dietspotlight Burn are so certain of their product they’re offering a Special Trial Offer, which is a good sign.

3 Week Diet Ingredients

We dug deep into the 3 Week Diet ingredients to give you the details you need.

Introduction Manual

This is an introduction to the diet delivered in eBook format. Inside it, you’ll learn the science of weight loss and what you need to do to combat stubborn body fat.

What is it Supposed to Do?

Beyond giving you an introduction to the diet itself and how it works, it provides a list of supplements you should use, though those are not released before buying the program, as well as the science beyond the supplements.

Clinical Research

Unfortunately, without knowing the supplements the program suggests, we cannot find science to support them.

Clinical research is an important part of the equation when it comes to choosing a diet supplement. You may want to take a look at a product like Dietspotlight Burn, which is formulated with clinically tested ingredients.

Diet Manual

This is the diet guideline, also delivered in eBook format, that shows you how to calculate your lean body mass and your fat percentage.

What is it Supposed to Do?

Once you know your body type, there is a plan that’s tailored to your body type for “rapid weight loss” that shows you what to eat every day, how much to eat, and when to eat it. We don’t know what type of diet it suggests.

Clinical Research

There’s a lot of diet information out there. According to a study published in The New England Journal of Medicine, “In the analysis in which base-line values were carried forward in the case of missing values, the group on the low-carbohydrate diet had lost significantly more weight than the group on the conventional diet at 3 months (P=0.001) and 6 months (P=0.02), but the difference in weight loss was not statistically significant at 12 months (P=0.26).” [1]

Workout Manual

The workout manual is an exercise eBook to help you double your results compared to just diet alone.

What is it Supposed to Do?

The workout manual includes a full body workout, complete with two ab exercises to help you blast fat from your mid-section.

Clinical Research

According to a study published in Annals of Internal Medicine, “The addition of exercise to diet intervention produces more weight loss than does dieting alone. Exercise has a favorable effect on body fat distribution, with a reduction in waist-to-hip ratio with increased exercise. Exercise is especially important in maintaining weight loss in overweight persons.” [2]

Mindset & Motivation Manual

Weight-loss is hard, and it’s even harder if your mind isn’t in the right place. This is the final eBook in the program.

What is it Supposed to Do?

This book is supposed to help you change your mindset to a positive one that will help with weight-loss. There are also motivational tips and tricks that are supposedly to help you keep on track with your diet and exercise goals.

Is There Anything Out There That TRULY Works?

While this may be a good foundational program, we can’t speak for how well the supplements work, or if they even matter. We can recommend Dietspotlight Burn, a supplement made with clinically tested ingredients, may be a good option. All customers can take advantage of a Special Trial Offer, currently available.
