How to Follow
The Beachbody website offers a simple guide for those new to the 21 Day Fix.
You can order the program through the Beachbody website or Team Beachbody coaches via social media.
After unboxing the 21 Day Fix guides, portion-control containers and workout DVDs, dieters follow the steps listed on the Quick Start guide.
1. Follow Your Workouts
The 21 Day Fix comes with two DVDs that include six 30-minute workouts.
- Upper Fix: Targeted resistance training for the upper body (chest, back, shoulders, arms and abs).
- Lower Fix: A workout designed to “firm and tone your entire lower body while you blast fat and burn calories.”
- Total Body Cardio Fix: A full-body cardiovascular workout with weights to increase heart rate and burn calories.
- Cardio Fix: A second cardiovascular workout without weights.
- Pilates Fix: A Pilates-based workout that aims to strengthen the abdominals and firm the thighs.
- Yoga Fix: This is a restorative yoga-based workout used to improve flexibility and balance.
The 21 Day Fix workout calendar encourages dieters to complete at least one workout every day of the week.
2. Find Your ‘Container Plan’
Before diving into the meal program, 21 Day Fix followers must calculate their own calorie needs.
In the starter guide, a mathematical equation is provided to estimate overall calorie needs.
The resulting calories determine the right plan for you and tell you how many servings of each color-coded container you can consume per day.
Each container is a different size and is meant to be used for a specific food group:
- Green container (one cup): Vegetables
- Purple container (one cup): Fruit
- Red container (3/4 cup): Protein sources
- Yellow container (1/2 cup): Carbs
- Blue container (1/3 cup): Healthy fats
- Orange container (two tablespoons): Seeds and dressings
Dieters are also allowed two to six teaspoons of nut butter and oils, depending on their target calorie range.
Four “Container Plans” with different calorie target ranges exist:
- Plan A: 1,200–1,499 calories
- Plan B: 1,500–1,799 calories
- Plan C: 1,800–2,099 calories
- Plan D: 2,100–2,300 calories
Depending on your plan, you’re allowed the following number of containers per day for the different color-coded categories:

If estimated calorie needs are more than 2,300, it’s recommended to round down to 2,300.
3. Plan Approved Meals
After figuring out how many servings of each food group can be consumed per day, 21 Day Fix followers aim to eat the recommended amount of each container daily.
The 21 Day Fix kit comes with a tally sheet that makes it easy for followers to keep track of their daily container consumption.
The tally sheets provide six spaces for daily meals and snacks along with eight slots in which dieters jot down their daily water consumption.
The 21 Day Fix program recommends certain foods and recipes, but dieters ultimately decide what approved foods to eat when following the program.
The 21 Day Fix diet plan delivers a lower-carb macronutrient distribution of roughly 40% carbs, 30% protein and 30% fat.
4. Track Your Progress
Those following the 21 Day Fix are encouraged to track their weight loss progress in different ways.
Before starting the program, it’s suggested that you take a “before” picture.
Participants also use body measurements of the arms, chest, waist, hips and thighs to gauge how many inches are lost during the three weeks.
After completing the 21 Day Fix, “before” pictures and measurements are compared to “after” pictures and measurements to estimate total progress.
SummaryThe 21 Day Fix involves calculating calorie needs, consuming portion-controlled meals and completing daily workouts for 21 days.

SummaryThe diet encourages only consuming 21-Day-Fix-approved foods, including lean proteins, vegetables and healthy fats.
Foods to Avoid
Though the 21 Day Fix package does not tell dieters that certain foods are off limits, it advises to only consume approved foods.
As a whole, the Beachbody organization discourages unhealthy foods like sugary beverages and emphasizes nutrient-dense foods for those following their nutrition programs, including the 21 Day Fix.
When following Beachbody nutrition programs, the following are not recommended:
- Added sugars: Sugary beverages, sweetened yogurts, candy, baked goods, table sugar, etc.
- Refined carbs: White pasta, sugary cereals, white bread, bagels, white rice, corn chips, tortillas, etc.

- Greasy and fried foods: Fried chicken, French fries, potato chips, burgers, pizza, deep-fried foods, etc.
- Alcohol: Beer, wine, liquor, etc.
Added sugar, processed foods, refined carbs, fried foods and alcoholic beverages are strongly discouraged during the 21 Day Fix.
Health Benefits
There are several reasons why the 21 Day Fix has gained such popularity among those looking for a quick way to drop pounds.
May Help You Lose Weight
The 21 Day Fix meal plan suggests several practices proven to promote weight loss.
For example, research shows that cutting out added sugars and processed foods are effective ways to lose body fat.
A review of 68 studies found that people who consumed added sugar and sugar-sweetened beverages were more likely to be overweight or obese compared to those with low sugar consumption (2).
Another study in over 4,000 people demonstrated that those who ate fast food more than three times per week were 33% more likely to be obese than those who did not eat this type of food (3).
Plus, those following the 21 Day Fix are instructed to eat a high-protein, high-fiber diet and drink plenty of water, methods that have also been shown to be particularly powerful in promoting weight loss (4, 5, 6).
Supports Healthy Eating
The foods emphasized on the 21 Day Fix meal plan are healthful, nutrient-dense foods, including vegetables, complex carbs and lean proteins.
The program urges participants to prepare meals at home and cautions against relying on quick, unhealthy food when on-the-go.
The color-coded containers ensure that followers of the 21 Day Fix consume plenty of nutritious foods from each food group daily.
Unlike weight loss plans that recommend processed, nutrient-poor foods like meal bars, frozen dinners and low-calorie packaged snacks, the 21 Day Fix promotes eating whole, healthful foods.
Containers Teach Portion Control
Portion control is an issue that can derail weight loss.
Using the color-coded containers is an easy way to control portions and may deter dieters from overeating, which may aid weight loss.
An 18-month study in 197 overweight adults showed that the use of portion-controlled meals resulted in significant weight loss and improved overall diet quality (7).
While this method can also be followed using measuring cups and spoons, the portable containers are convenient and may motivate certain people to stay on track.
Exercise Is Part of the Program
The 21 Day Fix comes with a three-week exercise program consisting of 30-minute workouts that target different areas of the body.
People who want to shed pounds often don’t understand the importance of physical activity when trying to lose weight and maintain that loss over time (8).
Since this program stresses the importance of engaging in daily exercise, followers may be more likely to continue to be physically active after the three-week period has ended.
SummaryThe 21 Day Fix encourages exercise, healthy eating and portion control, which are likely to promote weight loss.
Potential Disadvantages
Though following the 21 Day Fix may result in positive changes, such as weight loss and a stronger sense of portion control, it does have some potential downsides.
The Focus Is on Short-Term Weight Loss
As stated in the name, the 21 Day Fix focuses on a three-week, short-term period.
You may indeed drop pounds while on the diet, but the chances are high that you’ll regain the weight lost during the program once it’s over.
Any successful weight loss plan should focus on slow, consistent changes over time rather than rapid fat loss.
Beachbody Pushes Dieters to Purchase Supplements for ‘Faster Results’
Within the Beachbody meal plan, dieters are urged to purchase Beachbody products like Shakeology protein shakes and supplements, including the pre-workout supplement Energize and the post-workout supplement Recover.
Not only are these items expensive — one container of Recover costs $69.95 — but there’s no proof that taking them will maximize results.
The 21 Day Fix program costs $59.85, which may seem reasonable to some. However, if you add supplements and additional bonus workouts, the price begins to climb.
May Be Too Restrictive for Some
At the heart of the 21 Day Fix program are the portion-controlled containers.
While this may be an effective way to stop overeating, relying on containers and tallying intake may be too restrictive for some people.
Plus, this is not a realistic way to eat on a long-term basis, and continuously tracking portions and food intake may lead to disordered eating tendencies in some people.
Dieters Determine Their Own Calorie Needs
A major flaw in the 21 Day Fix program is that dieters must calculate their own calorie requirements.
Beachbody suggests an arbitrary 750 calorie deficit for all people following the 21 Day Fix, regardless of age, health status or gender.
Combined with daily workouts, negating 750 calories from overall intake will likely result in weight loss, but it may not be healthy.
For example, using the 21 Day Fix equation, a 145-pound (66-kg) person would only consume 1,245 calories during the program.
This is a meager amount, especially for a person who has an active job and is doing daily, sometimes strenuous, workouts.
Eating too few calories while participating in more activity than you’re used to could result in hypoglycemia (low blood sugar), mood swings and an increased chance of binge eating (9).
SummaryThe 21 Day Fix has some downsides, including cost, potentially unsafe calorie restriction and the focus on short-term weight loss as opposed to long-term lifestyle changes.
The Bottom Line
The 21 Day Fix uses daily workouts and portion-controlled containers to boost weight loss.
Though this plan may aid weight loss and improve diet quality, it also has drawbacks. The program focuses on short-term, dramatic weight loss instead of long-term lifestyle changes and may be too restrictive for some.
While following the 21 Day Fix will likely result in some weight loss, those looking for lasting results should focus on eating whole foods, practicing portion control and increasing physical activity on a long-term basis.
