I think I've tried to lose weight with all sorts of diets such as the soup diet and shakes, and also eating under a dangerous 600 calories or skipping meals which was all out of desperation. I finally took the time to feed some knowledge into my head on healthy eating and excercising and soon realised that commitment was all that it took to make ones success. I cut out late night snacking and watched my food portions. It depends on every individual and their obstacles.I lost over 35 lbs from including lots of physical activity into my daily routines and watching what I put in my mouth. Now and again I will eat at fast food places or treat myself to ice cream but it's not as much as I used to before. Today I'm still kicking near a 40 lb loss and plan to practice healthy eating and excercise for the rest of my life... or else it wouldn't be a'lifestyle change'
