sorry to hear Brad is struggling. Its hard enough to deal with our own struggles, but add in the struggles of the people we love and it all seems to get too heavy!!! Definitely diet is the best place to start. Sometimes the best we can do is just try to control the environment at home - that's what I try to do. Doesn't always work. Last night I sat and watched hubby devour about 1/2 of a bag of corn chips with the primal taco casserole I made. UGH! What do you do??? He says he wants to lose weight, but doesn't really want to change his eating habits.
How about getting the entire family out for a walk after dinner? It doesn't have to be long or quick - just a leisurely stroll through the neighborhood. Any movement is better than none.
