I just started this diet... I have lots of energy in the gym which is great... However I feel like I'm having some problems choking down all the food in the day...

I can barely eat the 8oz of chicken and the morning meal of 5 eggs and 4 eggwhites is impossible for me to eat. (I sub a 5 oz can of tuna and 3 eggs)

Do you have to eat all of what is required in the diet?
