there is something for everyone and there really isn't a 'best' one. any program that teaches you to eat in moderation and helps to establish a healthy approach to food in general is good. i'm a jenny craig fan, client and consultant and i find that program to be amazing and i stand behind it. if i didn't believe in it i wouldn't work there. however i know LOTS of people that are very big on weight watchers because it works for them. i tend to stay away from anything that says 'low' or 'high' as in low carb (you need mostly carbs as that's the biggest supplier of fuel for the body) and high protein, but again that's just a preference.
