Hello Melanie....congratulations on your lung transplant and best of luck with that. I have copd and I am on oxygen 24/7, so I can imagine how wonderful it must be to breathe on your own again .

welcome back to low carb eating. I too have lost, gained back and lost again. I have been losing now for several years, slowly, yes, but losing. This is the best way, the easiest way to get there as you found out when you tried the low fat route. Fat is so important to our health and this diet will allow you to eat fats that will keep you satisfied and help you to lose.

Lots of good recipes on this board and on the internet. Best of luck!
