Can you argue without a strawman? CICO deals with weight. If you want to LOSE weight, you must expend more calories than you consume. Period. End of subject. This has nothing to do with body composition. Starvation dieting will suck more mass from your lean tissue than your fat, and overeating poor quality fats will tend to store more of those calories as body fat than lean mass. Fats in general are more likely to store as body fat in a caloric surplus than carbohydrate because it is a less anabolic fuel source. Insulin is very anabolic, which is why you'll see bodybuilders looking to gain weight overconsuming protein and carbohydrate, not fat. Fat in large surpluses just tends to...make you...fat.
