You need a nutritionist not a trainer.
My wife could / Should be a Trainer / Nutritionist. She has competed in BB competitions. She did a lot of studying while training and learned a lot.
She is always yelling at me to eat right. Try watching what you eat limiting carbs (not cutting them out they are needed if you want your internal organs to stay with you) and eating 5 small meals a day. You will be amazed at the changes in 4 weeks.
My wife used this site for inspiration and information.
