Keto works...period...I eat a lot, and I drop a half pound to 2 pounds every week.
I snack on pork rinds and cheeze during the day, and eat a lot of vegetables at mealtimes with real butter or olive oil during the week, and I eat a lot of meat and veggies, and I mean a lot on weekends.
50 pounds and counting.
I will have a cheat weekend, or when we are traveling for a few days where I eat anything I want, but I only do that once every two months or so. I figure it's good to reset every once in a while.
That works for me.
