BistroMD has been around for a while and it’s a favorite for weight-loss programs that address unique needs like diabetes, menopause or gluten-free. They also offer different programs for men and women. You can choose 5 or 7-day plans that range from $169-$199 a week. That’s three entrees a day plus one My Night which lets you practice creating your own nutritious meal. You also get unlimited support from registered dietitians.
