No motivation

I spent the end of 2024 until probably mid 2025 on a weight loss journey. I had so much motivation and ended up losing 70 lbs. I hit the smallest weight I’ve been in years and then winter hit and I stopped doing my outdoor workouts, started eating worse and now have put 30 pounds back on. I’ve tried restarting my weight loss journey again and again but just can’t sick with it no matter how hard I try.
What are you doing to stay motivated and stick with your plan?
