What diet helps you lose fat without losing muscle?
Quantitative analysis of the caloric restriction versus isocaloric diets models based on macronutrients composition: impacts on body weight regulation, anthropometric, and bioimpedance parameters in women with obesity

Surprising Findings
Very low-energy diets increased waist circumference by 5.39 cm
Everyone assumes eating under 800 calories = fat loss. This shows severe restriction triggers fat retention and muscle loss—possibly due to metabolic slowdown or stress hormones.
Practical Takeaways
Aim for 1.6–1.8g of protein per kg of body weight daily while cutting calories—this helps preserve or even build muscle.

The metabolic improvements observed during initiation of very-low-carbohydrate or carnivore diets are primarily attributable to caloric restriction and elimination of ultra-processed foods, not to the physiological effects of animal product consumption alone.
When obese women eat more protein while losing weight, they tend to gain more muscle and lose more fat than when they just eat fewer calories overall.
When obese women eat fewer carbs (but not fewer calories), they lose more belly fat and shrink their waistline more than when they just eat less food overall.
When obese women follow a very low-carb, high-fat diet (ketogenic), they lose more belly fat and keep more muscle than when they just eat fewer calories.
When obese women eat extremely few calories (under 800 per day), they sometimes gain belly fat, lose muscle, and don’t lose much fat—making it worse than eating a little less.
