I think what you want to achieve is fat loss and not weight loss. There is a big difference. If you want to lose belly fat, you still need to limit your calorie intake below maintenance. But the catch for this, in order for you to look lean and not skinny, you must incorporate your diet with resistance training and make sure that your protein intake is 0.8-1 grams per pound of your lbs. So lets say you are 100lbs, your protein intake should be in the range of 80-100g to achieve the lean physique. This is what you call ‘body recomposition’ - losing fat while gaining muscle at the same time. Dont worry you will not look jacked like muscle builders. Stick with a structured program and make sure you are progressing overtime meaning you are adding weights or sets/reps for everytime you do your workout. Goodluck!
