Lockdown Weight/ Dietary Supplements

What dietary supplements have you used that actually work?? Since lockdown started for our state March 17, I remained pretty stagnant in my weight until mid-May. Illinois is still in lockdown and I’m gaining weight. I go on walks and get exercise a lot of the time by working in the yard and doing other things but I’m still snacking more! Call me vein but I really don’t want to gain any more weight! What supplements have actually worked for you? Or do they not? I’ve never had to try them!
