Yeah 72h fasts are the way to go, way more benefits than 48, but 48 has way more benefits than 24h.
All the lean people I know automatically eat smaller amounts and less carbs/sugar. Only when I started doing it myself and seeing results I was like damn, this is all it takes huh.
Fasting/keto helps my mental health and allows me to work long periods focused, really fires up my brain. I also manage stress a lot better and problem solve/find solutions quickest. Although that could also be because I’ve stopped drinking and smoking. Fasting also allowed me to destroy my cravings for carbs/alcohol/drugs.
No I enjoy making myself as healthy as possible. At 33 I’m not getting any younger and I want to be in peak condition, I abused my body with substances for years.
