My advice from someone that has been at low carbing (started on Atkins and now switched to Primal Blue Print after finding I have grain intolerances) since 2003.
Do not start Atkins and do induction to go back to counting calories.
Atkins is meant to be a lifestyle change that takes you through all 4 phases from start to finish no matter if you have 15 pounds to lose or 150 pounds to lose.
This is the primary reason that the media can spout their venom of saying that low carb doesn't work.............Because people do Induction, then go back to their calorie counting low fat way of life and yes you will gain back the weight you lost.
Sorry for being so blunt, but the mis-information that the media and a lot of people spread about the low carb way of life is really a thorn in my side because people think they can treat it like a "diet' and start and stop it when they want.
The low carb lifestyle is just that. A lifestyle that is meant to change your mindset and you are not there yet.
