Low carb living doesn't suit everyone, but if you are serious about losing weight, you are in this for the long haul. You can't lose 6 stone in a short amount of time without making some big changes in your lifestyle and eating habits - there's no magic cure.
I've done low calorie diets, and have failed miserably at them long term because I'm always hungry. Yes, I could have Mueller Lights and cereal, but not a lot of them. Trading that in for LC means I'm never hungry, and that means so much in my day to day life, and keeping with the program longer term.
I've lost 4 stone since May and feel pretty great about it, even though there's things I know I can't have anymore. But when I look at the calendar and see how long I've been able to keep it up, I'm thrilled! It hasn't seemed like a long, horrible slog - I've been able to live at the same time as losing weight.
Yes, sometimes it's discouraging when you have a week when you only lose 1 or 2 pounds, but other weeks have bigger losses and that makes it worth it!
Give it an honest try, and if it doesn't suit you, try something else. But just try something - if you aren't happy with your body now, change it.
