Cold turkey worked for me and I'm not even tempted anymore. I actually quit all carbohydrates cold turkey this time, except for basically induction-level veggies. The first time I low-carbed I played around with lc meal bars/shakes, lc breads, etc. and I was miserable with cravings. This time it's purely meat, vegetables, nuts, and high fat/lc dairy like cheese and heavy cream (and honestly, a good bit of decaf coffee, it's my only indulgence and causes me no issues), and I have absolutely no issues with cravings. I'm a much happier person. My advice is to not flirt with junk carbs at all. Btw, the cheese and heavy cream are purely to get enough calories to maintain and I have to force them down.

My diet is very liberating, as food has become a means of sustenance and nothing more. I hope this helps someone!
