I would use a website to calculate your tdee and then subtract about 500 calories from it. This should help you to lose about 1 pound per week which is great. If you try to limit your calories by too much it can make you miserable and often leads to giving up.
i aim for right around 1900cal/day though I know today I definitely went over on that, but it was still good quality food that I overdid it on, so I’m not sweating. Plus I had a good workout as well, which will help.
