Or testosterone, which isn’t necessarily great for weight loss, but is fabulous for body composition, which I’m sure many men would be satisfied with. Weighing 200 with 18% body fat is probably more attractive to many tall men than weighing 160 with the same body fat. Muscle also raises basal metabolic rate which is nice for fat loss.

TRT clinics are grossly overpriced, charging $300+ A month for $5 drugs, so there is almost certainly room to disrupt that market. I’d be willing to wager many obese men display hypogonadism too.
