Unfortunately, when you lose weight, you lose it all over your body, not in one particular spot.
So don’t buy or try anything that tells you the contrary.
I know you tell me that you eat really healthy, but you’re not losing weight so obviously something is not working, I would recommend you to start having small meals every 3 hours, if you already do this, then make your meals smaller. But don’t miss any, because you want your metabolism to be constantly working.

Good luck and try to do exercise, at least what you know you can do.

start mornig walk.
