Metabolism help please!?

Sloth_Life

Hi everyone! First time posting here. I am in desperate need of some advice. For years I have struggled with my weight. I have spent so long on super calorie restrictive/ very low refined carbs that my body really just got used to that being the norm. If I ate more the 500-700 calories per day or anything different than like chicken breast, keto bread, and eggs, fruit and veggies etc, I would rapidly gain weight. I've done research, and it said to eat the amount of calories you're supposed to eat regularly in order to fix your metabolism. (I eat healthy, have for years, so luckily that's not an issue as well.) So I tried that, and I just keep gaining weight, no matter what I do. My only goal is to honestly just be able to eat a normal healthy diet like other people without the weight gain. And to lose the 10lbs that I've gained when I was trying to learn how to fix this mess. So 137. If I lose more, cool, but it's not a need. I am 36yr old female, 147.9lbs and 5'4". I am eating about 1350 calories as of now, not sure if this is too much, just right, or too little. I just know I am tired of eating healthy and gaining weight lol. Any advice is so welcome please, I could really use some insight on this. Thank you!
