How to manage age-related fat that won't go away?

Hello

I'm eating a similar diet to before and taking walks every day on my own, but my belly and love handles aren't showing any signs of going away at all.

In the past, I could return to my normal weight quickly with just a little adjustment for a few days, but perhaps due to age-related weight gain, my metabolism has slowed and my body feels stiff. I don't think I can manage on my own, so I am looking into getting fat-dissolving injections or a prescription for diet pills.

Has anyone else suffered from age-related weight gain like me and seen results after receiving help from a hospital? Please give me some recommendations.
