Yep - THIS website :-)
Go to the toolbar above and in the Healthy Lifestyle section are loads of EXCELLENT articles on Nutrition, Fitness and Motivation - all written by well qualified people - Dietitians, Personal Trainers - I may as well give you the link to check these experts out - LOL! www.sparkpeople.com/community/residentexpe
Between them and us, your husband will soon be properly on his way :-)
While on SP it would pay to check out the Success Stories in the "Community" section of the toolbar above.
I would also suggest that you both use the Nutrition Tracker (you will both need to be members for that, tho') and enter all of your food into that so that you have the tools to stay on track :-)
I hope that is of some help to you !
