This show is becoming a bit predicitable, and i wish it was only an hour long. 2 hours seems too long to sit through watching people either make slow progress or slide backwards in their weight loss.
It is definitely hard work losing weight, but not impossible. I've gone from 237 to 175 since March of last year on a medically supersvised weight loss program, under a doctor and dietician's care and using 2 meal replacements and one lean/green meal a day, and now only 15-18 lbs from my goal. There are definitely permanent changes I realized I had to make. I used to love cheese, peanut butter, and sweets like cookies/snack cakes and now I barely eat them, except on rare occasions, and even then it's a limited amount. Over time, I don't get as hungry as I used to, and my blood sugar and blood pressure are now normal. Once these people lose a significant amount of weight, they shouldn't be as hungry either. Their continued overeating is simply a behavior that they need to address and take steps to correct. Find other things to do, like walking, hobbies, join clubs, anything that doesn't revolve around food.
