Fat Loss Is Harder Than Weight Loss
Pure weight loss is easy — eat at a deficit, lose mass. Fat loss with muscle retention is harder because it requires the deficit AND adequate protein AND consistent training. Most apps optimise for the first variable and ignore the second; the result is weight loss numbers that look good and body composition that doesn't.
