SWMBO has lost, since the end of June, almost 30lbs by going high-fat and low-carb, combined with intermittent fasting. Another 30-35lbs and she’ll be back to her high school weight, at which time she was pretty athletic. It definitely works! I might give it a go, but I won’t do the intermittent fasting because I have issues as it is with nausea if I don’t eat enough between when I take PD meds.
