Interesting observation today.
Woke up with 85G and 0.2K
When I’m in real ketosis > 1, I feel no hunger during the day… and eat OMAD with no issue.
Ever since I’ve switched to high protein (low ketones) low fat, I am hungry during the day. This is uncomfortable but seems to be working for these last 15lbs of fat loss and to grow 10lbs of muscle.
I also used cold packs to add thermogenesis and mitochondrial growth (browning adipose) and that generally increases ketone production on OMAD. It’s been effective for spot reduction but only with high ketones from fasting.
I tried it today with low ketones and my body did not like being forced into that state. The hunger I experienced was severe and sudden. Stomach grumbling like a beast and approaching hunger pain. It’s during my “switched off” eating period so I can ignore it. But as an impartial observer, I have to say “Wow”… that’s an impressive reaction for someone who’s fat adapted and endured weeks of fasting.
My hypothesis is that the high protein, higher glucose/insulin and low ketone state is especially vulnerable to hunger when ketone preferring forces are brought to bear. Thermogenesis is the perfect example of this. It’s cold enough to force heat generation but not enough to cause shivering. I think low intensity cardio and weightlifting would have similar effects.
I wish that I didn’t have to go through the hunger pain, but I will say that being fat adapted by eating high fat first gave me the mental fortitude to know what my body can do. Then fasting pushed it further… but I felt weak at 160lbs on keto/fasting. But the OMAD discipline lets me say “no” much easier. Eating is just not something I do during the “off” time - no matter what. Technically it’s not “no”, it’s just “not yet”.
Also, I’m not hangry - I’m a little irritable but still calm unless provoked…
Just sharing my observations on the lab rat under study.
