I imagine anyone who is researching diets this heavily and is willing to sign up for a weird one may have lost weight regardless of if they used the potato diet or not - they committed to serious lifestyle changes that caused them to lose weight. Maybe it’s potatoes, maybes it’s everything the person changed in their and potatoes didn’t offset those.

And also, they're not eating out. This is a 100% vegetarian home cooked diet. At least for most Americans, even if there's literally no other mechanism in play, that's an absolutely massive change.

That could be a riff you contribute to this study. Only potatoes at home, but eating out. Probably would be similar to their half-potatoe diet though

I agree, restriction-based diets (restricting food choice, amount, or timing) virtually always yield positive results initially. If that phenomenon is a given, then digging deeper into the variations could help us understand why that is the case.
