Finding Your Sweet Spot

I'm struggling with all the conflicting information about fasting right now. I've heard several podcasts talk about women in middle age not doing fasted workouts in the morning or fasting until later in the day. I had lost 35 lbs a few years ago with afternoon eating windows of around 4-5 hours, but this past 6 months, I gained 20 lbs over the holidays and just can't get it off. I know I have a lot of hormonal issues right now, so what worked before isn't working now. I'm planning to try opening my eating windows earlier in the day with protein and ending them by early afternoon, aiming to stretch the eating time to 6-8 hours to get more protein in. I'm hoping this will help. I'm afraid I might eat too much with a longer window, but adding more protein should help. I also try to get most of my protein from food, but it's hard, and I will probably need to add some protein or collagen powder to my meals to hit my goals on a lot of days. Is this approach reasonable?
