It is too simplistic to reduce the complex relationship between food, eating habits, health to lower calories = lower nutrition.
There's a lot of scientific studies out there.
You can eat a 2000 calories cake and your body's needs for nutrition are not met, and it is starving. You can die from this diet.
Whereas eating a 800 calorie diet with lots of colorful fresh organic vegetables, healthy fats and lean protein of various kinds is vastly superior to a conventional high calorie (1600+) diet of meat, dairy and potatoes.
Of course but 800 calories of healthy foods is still way too low - I just told u above what these types of diets are used for and the health risks involved it’s ridiculous Eteri is making/allowing this for Alina
