Lose 21 Pounds in 21 Days Diet Plan

Do you want to lose weight fast? Your search for a solution may have pushed you into trying all kinds of diets like the Military Diet, Keto Diet, and the Vegan Diet, but unfortunately, none of these may have worked for you. The Three-Week Diet Plans may be what your body needs because some testimonies (including the before and after photos) prove that these weight loss meal plans deliver what they promise – a tremendous weight loss in three weeks (4).  Although, this remains controversial.

Get Ultimate 28 Days Meal & Workout Plan

The three-week easy diet for weight loss is meant for people who want quick results but have little time to follow more extended diet plans. Getting into a three-week weight loss commitment is no walk in the park, so you need to understand what you are signing up for. You should brace for a massive cut on calories, which will test your tolerance to a steady caloric deficit throughout the program.

Three-Week Diet Plans To Lose Weight Fast

Do the three-week meal plans really work? Individuals worldwide have curated bizarre diets to lose weight fast, for example, those that give you tips on how to lose 10 pounds in 2 weeks with guaranteed weight loss . Here is everything you need to know on how to lose weight in 21 days (particularly weight loss coach Brian Flatt's Three-week Diet and the Three Weeks to Summer Shorts Plan), including the meal plan, pros, cons, and its effectiveness.

Three-Week Diet Plan By Brian Flatt

How much can I lose in 3 weeks? Brian Flatt's three-week diet is designed to help you lose between 12-23 pounds in three weeks from your thighs, waist, hips, belly, and butt (4) ( 1 ).

How Does It Work?

The three-week diet plan is divided into three phases (each week), each with a unique set of nutritional requirements (all low in carbohydrates and calories ), tailored to help you achieve your weight loss goal (2) ( 5 ). Throughout the program, participants are guided on the kinds of food they should eat to shred as much fat as possible. The aim is to maximize fat loss at the beginning while gradually introducing more whole foods, then eventually progress towards a nutritionally balanced and complete diet to maintain a healthy weight ( 5 ).

This weight loss meal plan is based on five techniques to help your body burn fat faster ( 5 ). These are:

  • Reduced carb intake
  • Use of supplements (strategic supplementation)
  • Intermittent fasting
  • Calorie reduction
  • Exercise

Each of the methods above may significantly contribute to weight loss, depending on your target, so it is not mandatory to incorporate all of them. However, implementing all of them together will result in rapid weight loss ( 5 ). Flatt's three-week diet is made for people who seriously want to learn how to lose weight in a week or three. Remember, you will have to pay for the full diet system, including the introduction, meal plan, workout plan, and motivation manuals.

After the three weeks, you should continue weighing yourself every day. If you weigh three pounds or more above your target weight, start Phase 1 immediately and continue until you get back to your target weight (it should take about 1-2 days). You can therefore enjoy "cheat" meals once in a while without affecting your weight loss progress.

Benefits

According to Globenewswire , the Brian Flatt Three-Week Diet Plan leads to the following health benefits ( 3 ):

  • Improved metabolism that leads to faster body fat loss
  • Healthier hair and skin
  • Toned skin and reduced cellulite
  • Lowered cholesterol levels and increased energy

The plan is easy to follow since it uses regular grocery store foods and readily accessible nutritional supplements that attack harmful triglycerides that can lead to stubborn belly fat ( 2 ).

Disadvantages

According to Freedieting, the meal plan is ( 5 ) :

  • Very restrictive
  • Involves dramatic calorie restriction
  • Eliminates carbohydrate foods such as fruit, starchy vegetables, legumes, and whole grains
  • Involves intermittent fasting that may be uncomfortable
  • Encourages the use of caffeine and nicotine pills, which may be harmful

Besides being careful about their diet, fitness coach Brian Flatt urges participants to engage in 20-minute intense workouts three to four times a week because burning body fat will be more effective if one engages in intense, full-body exercises instead of long cardio sessions ( 5 ). There is a manual for both passionate gym-goers and people who barely go to the gym. Remember that everyone's body is unique, so you may not get exact outcomes as another person who follows the same diet and workout routine.

Three Weeks To Summer Shorts Plan

Apart from Flatt's three-week diet plan, other weight loss meal plans can be followed for the same period. The Three Weeks to Summer Shorts Plan, in particular, is designed to help you lose a stone (7 pounds) in three weeks at the end of the program (6).
