I’ve lost 14 pounds in 3 weeks on a low carb, high fat diet, including 3 or 4 cheat days. I don’t necessarily stick to under 25 carbs per day. Sometimes I go as high as 50.
If you want to prevent diabetes, note that having a lot of stored iron stores causes it. Donating blood once every two years makes having excess iron less likely.
I have a similar plan. And it works well!
