Be careful about avoiding fats - it's actually not healthy to do that. You have to eat the RIGHT fats and in the right proportion. There's quite a bit of research showing that the low fat diets of the past 20 years have done nothing to address the weight problem of this country, and may be hindering it.
You definitely want fats from olive oil, avocado, nuts, fish and so on.
Rachael Ray has a lot of pretty simple recipes, and also a lot of quick meals plus some plans for doing a week's worth of meals in a weekend afternoon. You can try her magazine or TV show website or pick up one of her cookbooks (try the library before buying one to be sure you get the right one for your family). Jessica Seinfeld has done 2 cookbooks on doing healthier options that kids will like - one is called "Deceptively Delicious" and I'm not sure what the other one is called.
There's also so much research on how our foods are nutrient-deficient - we just aren't getting the values from our food anymore because of growing, harvesting, storage and processing techniques. So people are really deprived, their bodies crave nutrients, and so they keep eating. There have been some pretty responsible estimates from teams of dietitians that we'd have to eat 5000+ calories a day to get the same vitamins, minerals, trace elements etc. that our grandparents got from eating 2000 calories. In my work, we've found that effective supplementation with patented, comprehensive, non-GMO, absorbable nutrition works wonders with weight control (ending cravings, meeting needs, and without stimulating the central nervous system the way many "diet" products do). What's more, it's safe for kids, pregnant and nursing moms, the elderly, people with cancer, everyone. Anything you buy in a regular store that has warning labels on it is a bad idea, and anything in pill form is close to useless.
