Losing weight before having kids

Hi guys, so I’m 21 years old, 200 pounds and 5’5, so I’m not exactly small at all. I was on anti-depressants that made me gain 80 pounds, my body did not handle them well. I quit taking the medication over a year ago and haven’t lost any weight. I’m stressing because I want kids in the next few years, and if I don’t lose weight, I don’t want my weight to keep raising if I were to get pregnant in let’s say 2 years. Any advice on how to lose weight? I’ve been walking daily and eating healthier. Meals you guys recommend ?? 😊
