Ana Diets

Contents
Ana diets, also known as pro-ana diets, are extreme starvation plans promoted in pro-anorexia online communities.
Some people believe these diets are a shortcut to weight loss. The truth is that they are dangerous and can be life-threatening.
If you are following an ana diet or feel pulled toward one, please reach out to a doctor or someone you trust. In the US, you can call or text 988 if you are in crisis.
In this article, we explain the risks of ana diets, where to get help, and safer alternatives.

Benefits of Ana Diets
There are no real benefits. Any rapid weight loss comes from starvation and carries serious health risks.
The rigid rules can feel like "structure," but for people who struggle with disordered eating, that structure feeds the illness.

Plans with names like "Ana Boot Camp" circulate online. We don't list their rules here because every one of them relies on eating far too little.
Health Risks of Ana Diets
Ana diets mirror the restriction seen in anorexia nervosa. MedlinePlus lists complications of anorexia that include thinning bones, low potassium that can cause dangerous heart rhythms, dehydration, malnutrition and seizures.
They can also cause or worsen depression, anxiety and eating disorders.
Foods to Avoid on Ana Diets
Ana diets tell people to fear entire food groups and "high-calorie" foods. That fear is part of the harm.
A healthy diet has room for all foods, with fewer heavily processed snacks and sugary drinks and more whole foods.
Tips for Starting Ana Diets
Our only tip is not to start one. If you are thinking about it, talk to a healthcare professional about your goals first.
If you do want to lose weight and are not underweight, set realistic goals, such as losing 1 to 2 pounds a week with a balanced diet.
Exercise and Ana Diets
Exercise supports healthy weight loss, but exercising while starving the body is risky.
It can lead to dizziness, fainting and heart rhythm problems. Compulsive exercise is also a warning sign of an eating disorder.
How to Get Professional Help
If you are struggling with an ana diet or disordered eating, seek professional help. NIMH notes that eating disorders can be treated successfully, and early treatment is important for a full recovery.
A doctor or therapist can provide guidance and support. Treatment often combines medical care, nutrition counseling and therapy.
What to do if You Slip Up
If you have been following an ana diet, eating a meal is not a "slip up." It is a step toward health.
Be kind to yourself, and talk to a healthcare professional for support.
Alternative Diets
If you are looking for a healthy weight loss plan, there are many safer alternatives to ana diets.
Good options include the Mediterranean diet and the DASH diet, combined with regular physical activity.
Pros and Cons of Ana Diets

Ana diets can cause rapid weight loss, but the risks far outweigh it.
Pros:
- None that are worth the risk. Short-term weight loss from severe calorie restriction usually comes back and causes harm along the way.
Cons:
- Nutrient deficiency: Ana diets cut out entire food groups or drastically limit calories, which can lead to nutrient deficiencies and malnutrition.
- Physical health problems: Extreme weight loss and malnutrition can cause fatigue, weakness, dizziness, bone loss and irregular heartbeat.
- Mental health problems: Ana diets raise the risk of developing an eating disorder and can cause guilt, shame and difficulty concentrating.
Conclusion
Ana diets are dangerous and can lead to serious, even life-threatening, health problems.
If you are considering an ana diet, or are already following one, please talk to a healthcare professional.
