I have been off and on so many diets that it's not funny. I would stay on one from a week to five months and then go off it and start back eating again then I would gain all of my weight back + more. Of course your going to gain more back if you go back to eating exaclty the way you were before you started the diet, you can't help but not too. Look at it like this. If you had not started the diet where would you have been say 2 years from the start day? maybe 10-50 lbs more? Ok now Since you did start your diet and you did lose weight and you lost 30 lbs in 6 months then you stop losing you get bored and aggravated because you've reached a plateau and your thinking what's the point right? So, you stop your diet and pick up your old way of eating so of course your going to gain back everything you lost plus more.I think that everyone thinks their weight should stay the same while they eat unhealthy foods. Hey I would love to sit down to a BIG bag of chips and some french onion dip but I'm not going to and I'll never be able to do that again. I KNOW I can't touch anything sweet, as in chocolate cake that just came out of the oven with gooey melting chocolate frosting with a large cold glass of milk. I would love to grab a whole pan of cake and eat it, but I cant. I love Krispy Cream Donuts but I can never have one because I KNOW I can't stop at just one so I stay away from these things.
