What Is The ABC Diet 

The ABC diet is a controversial and potentially dangerous weight loss diet that involves severe calorie restriction over a period of 50 days. The diet is divided into several phases. In each phase, you’ve to consume a specific number of calories per day.

The name of the diet comes from the initials of the three different phases: Ana Boot Camp. The term “ana” was derived from the word anorexia, a serious eating disorder that has claimed many lives. And “boot camp” meant a strict, militant approach to weight loss, with little regard for the needs of the human body.

ABC diet starts with a meager 500 calories per day, which is barely enough to keep the body going, let alone provide the necessary energy for daily activities. As the program progresses, the calorie intake is gradually increased to 800 calories per day, but even this is considered an extremely low-calorie intake.

The ABC diet focuses on the consumption of fruits, vegetables, and lean protein while cutting out high-calorie and high-fat foods. It’s a diet that’s designed to be followed with military precision, with little room for deviation. The ABC diet promises significant weight loss in a short period of time, but the cost is high. Followers of the diet risk nutrient deficiencies, dehydration, and other health problems due to the extreme restrictions on calorie intake for a long period.

While there are some people who claims that ABC diet can lead to rapid weight loss, many health experts and medical professionals warn that the ABC diet is like a mirage in the desert, promising the end of the journey but only leading to disappointment and danger. It’s important to prioritize health and well-being over unrealistic beauty standards and to seek out safe and sustainable approaches to weight loss.

How Does The ABC Diet Work?

The ABC Diet, also known as the Ana Boot Camp Diet, is a trending diet among younger adults that claims to help lose weight quickly through extreme calorie restriction. At the molecular level, severe calorie restriction can trigger a number of physiological responses in the body in order to maintain energy balance.

During periods of calorie restriction, the body is forced to rely on its stored energy reserves in order to meet its energy needs. This triggers a complex series of metabolic responses, including the breakdown of stored glycogen (the storage form of glucose) and the mobilization of stored fat in order to produce energy.

In the early stages of calorie restriction, the body primarily relies on glycogen stores for energy. However, once glycogen stores are depleted, the body begins to burn stored fat for energy production. This process, known as lipolysis, involves the breakdown of triglycerides (the storage form of fat) into fatty acids and glycerol, which is ultimately used as fuel for cells.

As the body continues to rely on stored fat for energy, levels of circulating fatty acids and ketone bodies (a byproduct of fat metabolism) can increase. This can lead to a number of physiological changes, including decreased insulin levels, increased glucagon levels, and changes in hormone levels and metabolic pathways.

When calorie intake is severely restricted, as is the case with the ABC diet, the body may turn to muscle tissue as a source of energy. This is because muscle tissue contains amino acids, which can be broken down and used to fuel the body when calorie intake is not sufficient.

Protein catabolism can lead to a loss of muscle mass and strength, as well as a slower metabolism, which can make it harder to lose weight in the long term.

The overall molecular process ultimately leads to a lean body, deficient in fat and muscle mass.

Does the ABC diet work without exercise?

Does the ABC Diet work without exercise? Well, let’s spill the beans! The ABC Diet, with its extreme calorie restriction, might lead to initial weight loss even without exercise. But here’s the catch: that weight loss may not be all fat—it could include precious muscle. And nobody wants to lose muscle, right?

Exercise plays a vital role in maintaining muscle, boosting metabolism, and keeping your body in tip-top shape. So, while the ABC Diet might show some quick results, it’s not a sustainable or healthy approach.

ABC Diet Meal Plan

The ABC Diet consists of 50 days and is divided into 5 phases, with each phase lasting for 10 days. The phases of the ABC Diet are as follows:

Phase A (Day 1-10)

This is the most relaxed phase of the diet, and it allows for a calorie intake of 500 calories per day. This phase is intended to kickstart weight loss and prepare the body for the more restrictive phases to come.

Phase B (Day 11-20)

This phase requires a further reduction in calorie intake, with only 400 calories per day allowed. The dieter is encouraged to consume only liquids such as smoothies, soups, and protein shakes during this phase.

Phase C (Day 21-30)

This phase is the most restrictive of the diet, with only 300 calories per day allowed. The dieter is allowed to consume only fruits and vegetables during this phase.

Phase D (Day 31-40)

This phase allows for a slight increase in calorie intake, with 400 calories per day allowed. The dieter is encouraged to consume only lean proteins such as chicken and fish, along with non-starchy vegetables.

Phase E (Day 41-50)

This is the final phase of the diet, and it allows for a calorie intake of 500-800 calories per day. The dieter is encouraged to consume a balanced diet, consisting of lean proteins, fruits, vegetables, and whole grains.

The first phase of the diet is the most extreme, with a daily calorie limit of just 100 to 200 calories. During this phase, the only foods allowed are fruits and vegetables, with an emphasis on low-calorie options like celery, cucumbers, and lettuce.

As the diet progresses, more food groups are gradually reintroduced, with each phase having its own set of rules about what can be eaten and how much. For example, some phases may allow for the consumption of lean protein, while others may focus on high-fiber foods like whole grains and legumes.

The ABC Diet also has strict guidelines about when to eat and how often. Some phases may require you to eat only one meal a day or to skip meals altogether. In addition, the diet may recommend drinking large amounts of water or other low-calorie beverages to help curb hunger and flush toxins from the body.

Side Effects of Anorexia/ABC Diet

The ABC Diet is a highly restrictive diet that involves severe calorie restriction and may lead to several physiological changes in the body. Here are some of the key results you’ll observe after an ABC Diet:

  • Slowed Metabolism: When the body is deprived of calories, it enters a state of starvation and begins to slow down its metabolic rate in order to conserve energy. This can make it harder to lose weight and may lead to weight gain once the diet is over.
  • Muscle Loss: Severely restricting calories can also lead to muscle loss, as the body breaks down muscle tissue to meet its energy needs. This can lead to a decrease in overall strength and a slower metabolism.
  • Nutrient Deficiencies: The ABC Diet may not provide adequate amounts of essential nutrients such as protein, vitamins, and minerals, which can lead to nutrient deficiencies and related health problems such as anemia, weak immune system, and impaired organ function.
  • Mood Swings and Fatigue: Restricting calories can also lead to mood swings, fatigue, and low energy levels. The dieter may experience difficulty concentrating, irritability, and decreased motivation.
  • Dehydration: The ABC Diet involves a significant reduction in fluid intake, which can lead to dehydration and related health problems such as headaches, dizziness, and decreased kidney function.
  • Extreme hunger and cravings
  • Difficulty concentrating
  • Constipation or diarrhea
  • Hair loss and dry, brittle hair
  • Dry skin and brittle nails
  • Weakened immune system and increased susceptibility to illness
  • Disordered eating patterns and unhealthy attitudes toward food
  • Increased risk of eating disorders and other mental health issues
  • Nutrient deficiencies and health complications associated with them, such as anemia, osteoporosis, and heart disease.

Is ABC Diet effective for weight loss

At first glance, individuals embarking on the ABC Diet may witness initial weight loss due to its severe calorie restriction. By cycling between very low-calorie days and higher-calorie days, proponents claim that metabolism is stimulated, leading to accelerated fat burning. Yet, it is essential to understand that the apparent effectiveness of this diet is marred by a range of concerning factors.

How Much Weight Can You Lose on Ana Diet

The amount of weight loss that can be achieved on the ABC diet is highly variable and can depend on individual factors such as starting weight, body composition, and adherence to the diet. The results of ABC diet aren’t same for all.

However, based on reports from those who have followed the diet, it seems that those who are already underweight tend to lose 10 to 20 pounds, while those who are overweight may lose 20 to 25 pounds. It is important to note, however, that these figures are based on anecdotal evidence and are not scientifically verified.

What would be easier for you, fasting or the ABC diet?

Fasting can be challenging for individuals who are accustomed to regular meal patterns or have specific dietary requirements. It may involve abstaining from food for extended periods, which can be mentally and physically demanding. Some people find it easier to adapt to intermittent fasting schedules, where they have designated periods of eating and fasting, as it offers more flexibility.

On the other hand, the ABC Diet entails severe calorie restriction and follows a specific regimen of alternating low-calorie and higher-calorie days. This extreme approach may be challenging to sustain, as it can lead to feelings of deprivation, nutrient deficiencies, and negative impacts on mental and emotional well-being.


We don’t recommend following the ABC Diet at all. The ABC Diet is not a safe approach to weight loss. Its extreme calorie restriction can lead to harmful side effects like nutrient deficiencies, weakened immune system, fatigue, dizziness, and dehydration. Instead, a balanced and sustainable approach to weight loss through a healthy diet and regular exercise is recommended.

ABC Diet Results & Reviews

The diet is specifically designed for those who are significantly overweight or obese, and it has produced positive results in the short term. However, you must be aware of the dangers and potential risks.

The ABC Diet promises a weight loss of 20 pounds in just 50 days, but it’s a risky approach. The extreme calorie restriction can cause weight retention and regain after completing the diet. It’s crucial to consult with a healthcare professional before starting any restrictive diet to ensure safety.

According to user reviews, the ABC Diet can cause severe fatigue, weakness, and dizziness. One user shared, “I felt tired all the time, and my brain was always foggy. I couldn’t focus on anything and felt like I was running on empty.

Another user reported experiencing abdominal pain and bloating, saying, “I felt like I had a constant knot in my stomach. The bloating was so severe that I looked like I was several months pregnant.

The ABC Diet can also lead to dehydration, which can cause kidney problems and other health issues. One user noted, “I was constantly thirsty and had to drink water all the time. My urine was always dark, which was a clear sign that I was dehydrated.

Furthermore, the ABC Diet can cause nutrient deficiencies, leading to weakened immune systems, dry skin, brittle hair, and hair loss. One user reported, “My hair started falling out in clumps, and my skin was so dry that it felt like sandpaper. I felt like I looked 10 years older in just a few weeks.

The ABC Diet can lead to unhealthy attitudes and behaviors around food. One user shared, “I became obsessed with calorie counting and would avoid social situations that involved food. It took a toll on my mental health and relationships with others.

What is Pro Ana Diet

The term “pro-ana” is short for “pro-anorexia.” It refers to a subculture that promotes and encourages anorexia nervosa, an eating disorder characterized by a restriction of food intake and an obsession with body weight and shape.

The pro-ana movement started in the late 1990s and early 2000s, primarily on internet forums and social media platforms. Pro-ana websites and social media accounts promote and encourage anorexia nervosa as a lifestyle choice, often portraying it as a way to achieve a certain body type or as a form of self-expression.

The term “pro-ana diet” refers to a type of extreme calorie-restrictive diet promoted by the pro-ana subculture. This diet encourages individuals to restrict their food intake to dangerous levels in order to achieve weight loss and a particular body shape. However, these diets are not recommended by medical professionals as they can lead to severe physical and mental health consequences, including malnutrition, dehydration, weakened immune system, slowed metabolism, and disordered eating patterns.

Both pro ana diets and ABC diets are extreme calorie-restrictive diets that promote unhealthy and dangerous eating habits. Pro ana diets are typically associated with anorexia nervosa and are promoted by the pro ana subculture, while the ABC diet is a specific type of pro ana diet that involves consuming very low-calorie amounts of food for 50 days.
