Carbs are not the issue.

I would do the following:

1. Make sure your scale is accurate and precise and get a better scale if it isn't, as if the thing you're using to measure yourself isn't giving you your actual weight, but is varying a few pounds each time, that's a sure route to frustration. I recommend the HealthOMeter balance beam scales, but that may be a bit spendy.
   
   
2. Add more vegetables/fiber. Green veggies have a fairly inconsequential level of carbs, and will help your problematic digestion.
   
   
3. Add fermented foods. Get some sauerkraut or kimchi from the refrigerated section of your local supermarket or health food store. Get the refrigerated stuff which has live probiotics. It's low-carb, and will help your gut biome readjust and get healthier. (It may also mellow you out if that's an issue.)
   
   
4. Do the math on your food intake, don't just ballpark it. Get a kitchen scale if you don't have one and pull the nutrition data online and make sure you know the calories/macros exactly for every meal.
   
   That's what I'd do, but YMMV.
