Intermittent fasting and Keto changed my health like nothing else. Congrats!
Woot! 154 lbs to just under 147 lbs in 22 days. And more importantly, 20% body fat down to 17.4%. At my size, that's a pretty big difference from feeling a little tubby to almost approaching trim.
strict keto + 16/8 intermittent fasting.
First time trying intermittent fasting. It got me into keto faster than any time prior. Blood ketone levels crushing it (3.1mmol/L spike yesterday! Usually 1.5-2.0).
16/8 is really easy w/strict keto. Barely ever really hungry and when I am it's like a 3 out of 10. I'm not counting calories. Not worrying about limiting portion sizes.
Basically just eating the same two meals each day: cheddar-kimchi-miso paste omelets, avocado, broccoli; salmon, avocado, broccoli dinner. Haven't increased my exercise, though nostr:npub1kumadawgefxjt2c293whsan5sfmdg5tylm0uk39enc6uxxfy5m4scrz2v7 and I typically do 2.5 mi in walks a day regardless.

I realized that I was already so close to doing it anyway. My default meal is keto, though I had gone through a period of being keto by default but not strict, so never actually entering or maintaining ketosis. And I stopped eating breakfast years ago.
So really it was just being a little more strict and no evening snacks. Not a huge change.
Have you played with your on/off range? I was tempted to be a little more hardcore than 16/8 but wanted to start easy and so far have zero complaints.
