Hey Atkins is definatly a great way to get into ketosis, stick to it and you'll be in ketosis in a few days.
Don't be depressed about the weight gain, think we've all put weight on over Xmas, it will soon come off again
Good luck xxx
Don't be depressed. Atkins works really well especially if you know you are sensitive to carbs. I have achieved a body & health that I never even dreamed of when I started. Good luck!
