Starting engine 2 with hubby and need some help

Happy New Year's Eve :) to make this short I am fairly a healthy eater and exercise often. I am happy with my weight and not looking to lose anymore. I am gluten free also. My hubby on the other hand is not so healthy at all BUT he is willing to make some changes and try something new. He brought up the engine 2 diet and I am willing to try anything and think that I will do well but I want to make it a lil easier for him. Any suggestions? I am so happy that my hubby is looking forward to a new lifestyle.
