OK i read that for gaining weight but keeping definition it is good to "keep protein intake REALLY high, keep simple carbs and saturated fats to a very minimum, stick with glucose for sugars when you can and keep your fiber intake high."
Is this true?
It also said to do some isolation exercises, should i do this also?
Just get as strong as possible and eat as much as you can until you see some changes in a years time and if not happy change your diet/exercise accordingly.
