Trying to lose weight

Hello just joined this group. I am at my heaviest I have ever been at 305lbs. I always told myself I would never let myself get to 300lbs. This is heavier then I was when I was 9 months pregnant with my daughter. My goal is to lose 60lbs before I TTC. I just had a MC at 14 weeks and have gained 10lbs since then. I’ve done all sorts of crash diets, low carb high protein, and keto. I’ve also been on phentermine and hated it. But nothing I’ve really been able to stick on. Does anyone have any tips or things that helped you stay on weight loss?

Any help or advice is appreciated.
