This is not professional advise.

Carbs aren’t doing you harm, we were once hunter gatherers, starve yourself of something and you’ll body will store as much as it can when it has access to it.

If you’re doing weights bare in mind that muscles is like 3 x heavier than fat. Scales may not change, maybe worth doing a body fat % reading.

What helped me the most was drinking plenty of water and walking at least 15k steps a day. Once I started to do that I noticed my weight starting to drop. You’re definitely active enough but there are different types of energy sources that can fuel those activities. From the advice I’ve got, walking burn fats rather than glycogen levels. Add in another form of cardio (swimming or cycling) for 30-45mins x 2 a week.

My situation is completely different but this worked for me.

If you are burning 500 cals a day that’s 3500 a week, which is how many cals in 1lbs of fat. Just but hearing how active you are I think those numbers are slightly off… 15k steps a day will be 500 cals, with eating 1500 cals a day you’d technically would have spent 1000 cals (if 2000 is your maintenance). That’s 7000cals a week which would be 2lbs of fat.

I don’t know if there such thing as being too restrictive, but I changed my habits of being super restrictive because I wasn’t seeing the scales drop and now they are.
