I think if we're looking at body fat percentage that's a very different question, and something that's probably more in the realm of biology than physics. But weight loss is simple, it's not going to be effected by medical conditions or "metabolism" if you can just reduce the mass of the Earth.
Metabolism/energy levels/etc are Calories Out. If your metabolism is low, your Calories Out is lower.
Look at BMR, such as https://www.active.com/fitness/calculators/bmr
Very simple. CICO.
e: there are relatively rare medical conditions, such as water retention, that can affect weight loss. A better term might be "body fat percentage". But the end result is that if you want to lose body fat, consistently intake less calories than your body uses for energy.
