@Kelly. Oh I've reached my goal months ago; I actually lost 13lbs more than my original goal. I'm just maintaining now, but will check out Slimming World.

To Thelma slimming world when you reach your goal it is free xx

I agree that you should still be able to enjoy your food, and at least have one " cheat meal," so you don't binge eat & feel deprived.

Slimming world is fantastic. I have tried clean eating cutting sugar etc and could never lose weight. I don't have a gallbladder so the low fat is perfect for me. I lost 5 pounds in one week and have been losing since.

Didn't the inventor of The Atkins diet die of a heart attack? Too much red meat.

Vegan, vegetarian and paleo don't fit in with these. Those three are a choice of eating not a diet programme. Anyway, all of these diets are money scamming and ridiculous. I'll never agree with them, other than the three I've mentioned.

Or you could just eat healthy and exercise and stop messing with your bodies natural way diets are stupid and do nothing for you except confuse your body

Eat clean and have a cheese burger once in a while and exercise

So what happens when one reaches their weight loss goal? Are these healthy enough to continue? The only one that sounds like it can be long term is Weight Watchers. Eat "regular" or "normal" foods, just watch your calories. When I wanted to drop a few pounds, that's exactly what my doctor told me. 1200-1400 calories per day. I still enjoyed the things I loved, but I made healthier choices (no more fried foods, just grilled, etc..) Nobody should "diet." Make it a lifestyle.

Lost 60 pounds following paleo. Love it!
