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.

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 only eat during a short window each day (without counting calories), they lose less weight and gain more belly fat than when they eat fewer calories overall.

Individuals with low body fat percentages (<15% for men, <25% for women) exhibit diminished capacity for muscle hypertrophy under caloric maintenance or deficit due to insufficient endogenous energy reserves.

If you're a healthy woman with obesity and you eat very few carbs for 6 months, you'll likely lose more weight and body fat than if you eat low-fat foods — even if both diets have the same number of calories.
