My husband started a diet last year (May 2013). I cannot tell you the difference it has made in his roller coaster personality (ADHD). He has been more consistent with moods, doesn't get angry over every little thing and stays focused on conversation, and doesn't say wacky things that make no sense. He has always had a big appetite and he is now watching his calorie intake and has lost 90 pounds. I can not express enough what a huge difference this has made in him not only physically but mentally. Praise God!
