I am indeed on keto. I have done this diet a number of times-- this time has been the most successful and I'm lighter now than I have been since 2003, even though I haven't worked out at all for the past year and that decade included numerous periods of hard workouts.
I think that the difference this time is that I am consuming more fat. I will often have a teaspoon of coconut oil/butter for a snack, for instance, or in my coffee.
I try to eat zero carbs. I probably end up eating 10-20 grams per day in the form of barbecue sauces, in green vegetables or whatnot.
I don't count what I eat at all. I eat until I'm satisfied. I have very little desire to snack or anything of the sort, even though I basically do intermittent fasting-- I eat one large meal a day, usually consisting of a large salad with goodly dressing and cheese, and then some fatty meats.
Since I started the diet I've been losing weight like there's no tomorrow.
