1. Do you eat a lot of fibre in the morning for breakfast?
2. Eating at maintenance will keep you the same (ie maintaining). You wanna shed BF, you need to eat below maintenance (ie in deficiet) but maintain your protein intake on the higher side and keep lifting heavy. If you do it slowly, you shouldn't have any noticable drops in strength (and muscle mass). If you make a drastic cut in calories, then you will probably feel weaker and push less weight, lose BF and probably lose some muscle mass as well.
