Losing weight is becoming the need of many people, but not everyone knows how to help the body slim down. Currently, people offer a lot of diets as well as exercise, making it even more difficult for you to find a suitable weight loss method. Kerri Ann Jennings will help you get scientific meals through the 3 week diet plan shared in the article below.
How does a 3-week diet work?
The three-week diet plan is divided into three phases over three weeks. Each phase has its own set of nutritional requirements, but what they all have in common is that they’re all low in carbohydrates and calories, and tailored to help you reach your weight-loss goals. During the program, participants will be instructed on the foods they should eat to cut as much fat as possible. The goal is to maximize fat loss from the start while gradually introducing more whole foods. People will then adapt and gradually move towards a nutritionally balanced and complete diet to maintain a healthy weight.
The 3-week diet work is a plan based on five techniques to help people’s bodies burn fat faster. That is:
- Reduce carbs
- Use Supplements
- Intermittent fasting
- Reduce calories
- Exercise regularly
Each of the methods given above can significantly contribute to weight loss, depending on your goals, so it’s not imperative to combine them all. However, doing them all together will result in quick weight loss. This is Flatt’s three-week diet and is made for people who really want to learn how to lose weight in a week or three. Remember, you will have to pay for the full diet system. It includes an introduction, a meal plan, a workout plan, and a motivational manual.
After three weeks, we will have to monitor our weight regularly every day. If you are 3 pounds or heavier than your target weight, start Phase 1 immediately and continue until you are back at your target weight (it will take about 1-2 days). Therefore, you can occasionally enjoy comfort meals, without food selection, without affecting your weight loss process.

This diet plan also allows you to cheat with snacks, for example, you can refer to the 7 day smoothie weight loss diet plan recipe that Kerri mentioned.
4 Phases of the 3-week diet
Phase 1 (Days 1-7)
In fact, many people claim that they lose up to 10 pounds in the first 7 days of following the diet. This is the time for cleansing of the diet, so that one can remove toxins, accumulated waste and excess fat from the digestive system.
During the beginning of this phase, you will be given a detailed explanation of what foods are allowed to eat for the best results. There is a wide range of foods that are allowed, which are not overly restricted and still provide adequate nutrition, these include:
- Egg
- Turkey
- Carrot
- Cabbage
- Chicken
- Tomato
- Broccoli
- Spinach
- Beef
- And much more!
Stage 2 (Day 8)
Phase 2 doesn’t have to last for a week, it’s just a one-day phase. And it has a scary name for most people that is “24 hours fast”. But the special thing is that since you will be sleeping most of the time, it will be difficult for you to notice things happening. That is, today you eat your last meal of the day and then you will not eat again until dinner time the next day. This phase is not really difficult because you only need to skip 2 meals and then you will be able to eat again.
Of course, if you have a meeting at 4 p.m. and you don’t want anyone to hear your rumbling stomach. Sip on some raw veggies or drink black coffee (without sugar or creamers) or herbal tea to calm your body from the hum.
Stage 3 (Days 9 – 11)
People often refer to stage 3 as the “Fat Phase”. During this time you eat a specified amount of calories, with about 80 percent being fat. This may sound like the opposite of what one needs to do when dieting. But studies show that a low-fat, low-protein diet helps the body get rid of a lot of fat in a short amount of time.
A typical diet would be eggs and bacon for breakfast, salmon and avocado salad for lunch. Hard-boiled eggs for snacks, a juicy steak for dinner, and some nuts before bed!
Stage 4 (Days 12-21)
During this phase, people will gradually add more foods to their diet plan. You will receive a customized calorie plan to help you, based on your body weight and weight loss goals.
Now, your eating habits have changed a lot and you will find it almost effortless to stick to this diet. In fact, at the end of the 3 weeks period, everyone will be very surprised because the time also goes by very quickly and also loses weight very effectively.

- In the plan there is a period of intermittent fasting, so it is very harmful to the body.
- Diet plans that use drugs containing caffeine and nicotine cause a number of harmful side effects in the body.
Besides being careful about their diet. Fitness trainer Brian Flatt encourages participants to do 20-minute high-intensity workouts three to four times a week. Because then the burning of body fat will be much more effective if you participate in high-intensity, full-body exercises instead of long cardio sessions.
