My husband and I are doing what I call our own version of WW. We started 6 weeks ago and lost a total of 29 lbs combined (15 for him, 14 for me).
We cut out fast food and dining out, chips, desserts. I cook low fat meals. We watch how many carbs we eat a day as well as limit our calorie intake to around 1300. Still a lot of food considering most of it is fresh fruits and veggies. Portion control is key to a good weight loss plan.
