I am a boxer & have trouble losing body fat, will i get lean by eating 1.5g of protein per pound of body weight & about 150g of carbs per day?

Avoiding Carbs Key: From your statement, you are consuming far too many carbs. Reduce to less than 20-50g carbs total/day. Study my answer to question: https://www.Healthtap.Com/#user_questions/799030.

High protein diet: With low carb, at least no simple carbs, minimum good carbs initially will be good idea. And as you know, train aerobic and anaerobically daily. After weight lifting a good supplement of 30-40 gr of whey protein will be a good idea. Good luck.
