I just lost 28 pounds by switching my lunch to a 5 grams of fat or less Lean Cuisine and joining the Dimple Dell Fitness Center (Salt Lake County Recreation center). I have Altius Health Plans for health insurance and for three people, it is only $42 a month for all their classes at all of their 17 or so locations! I do their classes on Monday and Wednesday (for the last two months)and people have noticed the difference. I absolutely recommend it!
From September to April I've lost 28 pounds (the 1st 20 was the Lean Cuisine only)....Eat for health, don't buy the junk (then you won't eat it), watch the consumable calories in drinks (people always miss those) and work out for at least an hour three days a week. I lost it in 8 months (about 1-2 pounds a week) and it's going to stay off!
Daycare for my two kids is only $2.50 and hour, so there was no childcare excuse. They even have a TV showing the daycare in the classes so I can watch my kids! It's great!
Good Luck!
