Our story

Why I created Dr.Fit

I'm Yordan Bahov — a certified nutrition expert (ISSA). Before Dr.Fit, I built TOP Academy, the largest digital weight-loss platform in Bulgaria, and worked on the transformations of thousands of people.

I saw the same pattern again and again: people don't fail from lack of willpower. They fail because they follow diets that work against their biology — and after every one of them, the weight comes back.

It was never your fault. The problem is the system — so I built a new one.

The result is the three-stage Dr.Fit system: metabolic restart, carb rotation, and smart training. It's the foundation of the books and the app — in 6 languages.

The system

Three mechanisms. One direction.

Metabolic restart

21 days that break the diet cycle. You know what to eat — every day, every meal, without counting calories.

Carb rotation

From day 22 onward: a rotation that keeps your metabolism working and your results lasting — without the weight coming back.

Smart training

Short, structured workouts with built-in progression — at home or in the gym, based on your equipment.

The Dr.Fit app

The system that adapts to you.

The long-term form of the method — a personal coach and meal plan in your phone.

4 programs with over 120 workout templates and built-in progression
Daily menus with real food and calculated macros
Adapts to injuries, equipment, and preferences
28-day cycles with a reassessment after every phase

Questions? Answers.

What's the difference between the book and the app?

The book is a physical program for the first 21 days — nutrition, recipes, and short home workouts. The app is the long-term system: personalized training cycles and daily menus that progress with you. They work great together or on their own.

Do I need equipment?

Not necessarily. The book's workouts need no gym and no equipment, and the app builds your program around what you have — a gym, dumbbells at home, or just your body weight.

How are the app's programs personalized?

You enter your level, goals, and available equipment. The algorithm builds a progressive training plan just for you — with warm-ups, structured workouts, and built-in recovery.

Can I cancel anytime?

Yes. You cancel directly from the app or with a single link — no calls, no hassle. The book comes with a 60-day money-back guarantee.
