It is, of course, possible that there are other causal mechanisms at play. But I don’t think the evidence supports that.
Do you understand why people in science like placebo controlled trials? It’s because understanding causal mechanisms is hard.
There are a lot of people who try really hard to develop programs that are effective at inducing weightloss in a broad public and they fail. If weightloss is really simple then why don’t we have programs that show effective results in clinical trials?

Because it is hard to actually execute diets. You’re conflating two issues now.
There are exceptions, but people will lose weight very predictably if food intake and exercise is 100% controlled.
Dieting “theory” is all about helping people stick to the plans that engage the causal mechanisms that science already has informed us will work.
