I don't have any studies handy but here's what I remember from looking into this. IF does not lead to more weight loss than other diets when you match calories. At least some forms of IF also have lower adherence than simple caloric restriction.
My own anecdata suggests that I have better adherence to IF than regular caloric restriction. YMMV. The diet that helps you lose the most weight will be the one you follow closest.
Can only speak anecdotally.. but I find it relatively easy to stick to one or two meals a day over trying to do smaller/frequent meals. Same goes for avoiding carbs (keto macros). When I eat more frequently or start adding starchy foods, I'm ravenous the next couple days.
