Overview

What is the 3 Week Diet?

The 3 Week Diet Program is a manual-based system created by Brain Flatt which is designed to help consumers lose body weight and body fat in twenty-one days.

It is a diet system with specific manuals focusing on certain aspects of weight loss. The program consists of four instruction-based manuals, including the:

  • Introduction Manual
  • Diet Manual
  • Workout Manual
  • Mindset & Motivation Manual

Consumers can purchase the entire set, which is also available as a digital download, and start working on their weight loss with an accurately-designed meal plan.

How Did 3 Week Diet Start?

Brain Flatt, a certified personal trainer and sports nutritionist, created the 3-Week Diet.

According to him, other weight loss programs or diet plans are more targeted towards a slow approach to weight loss and do not help the user in shedding stubborn stored fat.

Those fatty acids from the stored fat combine with glycerol molecules and form a triglyceride. Thus, the 3-week diet plan is specially designed to work on those triglycerides, which normal diet plans are not able to target.

How Does the 3 Week Diet Work?

According to the 3 Week Diet Plan Program, there are four stages in this plan. The first stage contains a detailed explanation of what type of food users are supposed to eat.

It lasts for seven days and it specializes in eliminating toxins and clearing waste from the body. Certain foods which users can eat are as follows:

  • Chicken
  • Broccoli
  • Eggs
  • Spinach
  • Tomatoes
  • Turkey
  • Cabbage
  • Beef

The second stage makes the users do ‘The 24 Hour Fast,’ in which you are supposed to skip meals for one day. Certainly, this might be difficult for users who are doing this for the first time.

In the third stage, which lasts for two days, users are supposed to eat food with more calories and which might contain more than 70% fat.

fat-sources

This might sound contradictory to the claim of this product, though research proves that High Fat, Low-Carb diets help in losing weight.

The last stage is about adding more food to your daily intake schedule but with a precise calorie consumption chart.

The 3 Week Diet Plan also asserts that the users need not worry about gaining weight once again after losing it, as they can easily repeat Stage 1 and Stage 2 and can reduce their weight swiftly.

Does it Work

Results

3 Week Diet Results

Side Effects

Potential 3 Week Diet Side Effects

Immediate changes in food habits and diet plan can cause serious interference in body and mind mechanisms. According to a few reports, with sudden changes in dietary intake, the body may be severely affected.

Sudden modulation in diet intake may result in fatigue and constipation.

3 Week Diet Alternatives

The 3 Week Diet Program guarantees a weight loss of around twenty-three pounds within twenty-one days.

Nevertheless, certain instructions in the plan, such as the intake of caffeine, and a rigorous diet and exercising schedule, a one day fast, skipping breakfast and many other such specifications, may affect the user and might not provide them with a smooth weight loss program.

Therefore, we have also come up with alternatives related to the 3 Week Diet which overcomes the shortcomings of the 3 Week Diet Plan.

Eat Stop Eat

Eat Stop Eat is a 24 hour/7 days strategy-based diet plan which helps in weight loss. According to the creator, it increases fat burning hormones drastically.

Eat Stop Eat makes the user fast once or twice during the week. Users are not supposed to eat for 24 hours, but after that, they can resume their normal diet plan. During the fasting days, users can only have tea, coffee, water or diet soda.

ketosis and fasting

This practice is similar to intermittent fasting, though BioMed Central notes that more research is needed to determine its effects.

Weight Watchers Diet

The Weight Watchers Diet is a science-based point system guide. Users receive points based on the food they eat.

The guide supplies details to the users so that they eat more fruits and vegetables and eventually lose their weight. It also helps decrease their food intake, which previously consisted of food with ample amount of fatty acids.

It provides gentle guidance to the users so that their fruits, vegetables, and healthy food intake increases. With constant reminders and healthy food intake, consumers will surely lose weight in a specific time.

What Users Are Saying

What Users Are Saying

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

Bottom Line

The Bottom Line on the 3 Week Diet

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.

If you’d like to drop more weight, then we advise you to go with a diet plan 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 weight-loss programs we’ve seen this year is one called Noom. Some of the amazing things this diet program offers include customized meal plans, 1:1 coaching, interactive support groups, extensive food logging, and more.

The makers of Noom are so certain of their weight-loss program that they’re offering a free trial, which is great!
