Its much more likely that you are eating too much food, and or not doing enough/any cardio.
On ANY diet plan, if you are getting fat… It means you are eating too much food. Do not ever forget this.
Gaining muscle is a brutally, painfully, disappointingly slow process, and you have just learned that lesson first hand. Scale back the calories a little bit, make sure you stop gaining fat, and then give it several MONTHS before you decide you can’t gain muscle. Or years.[/quote]
YES, all intermediate/novice lifters (especially unassisted) need to be reminded of this!
Also, I agree with stronghold that most people will be able to gain muscle better on a diet that doesn’t eliminate any specific macronutrients for extended periods of time.
