Hi Taufik, switching a diet around to consuming a vast majority of calories from fat up-regulates a large number of processes that tune the body to burn fat effectively for fuel (e.g. with insulin levels low over time, fat can be effectively pulled out of fat cells). As part of this, a hormone called leptin (which reduces hunger) helps a keto-dieter…
Hi there, good question. Many articles point back to this 1967 study, which — for example — this review refers to when saying:
“…the ability to produce ketones has allowed humans to withstand prolonged periods of starvation. At such times, ketones can supply up to 50% of basal energy requirements. More interesting, however…
Hey Alex, that Hartman et al. article is a fascinating read. Thanks for sharing.
I did some digging into cognitive abilities & keto when writing my 43+ health benefits of keto article, and I found these two studies especially interesting:
Thanks Matt, you’ve hit on topics I’ve been extremely curious about: i.e. what specific levels of blood glucose trigger these hormone shifts, how can we best measure this personally, how does it relate to time-of-day, fasting, and overall insulin insensitivity, and what the heck is insulin insensitivity, anyway (biochemically speaking)?
Good question. Indeed taste sensitivities can change dramatically when doing keto (see relevant studies here, here, and here).
Mechanistically, as our bodies get more leptin-sensitive during and after induction, the concentration of sugars in our mouths required to cause a “sweetness” signal decreases (leptin is involved…
Hey Rey, while the “calorie in vs. calorie out” thing is true at the cellular level, it’s hormones that rule the macro picture. I’d probably phrase that a bit differently if I wrote it today.
100 calories from broccoli impacts your body differently than 100 calories from cookies.
Thanks for the heads up! Those links should be working now. We recently put up a landing page for our upcoming product and the old redirects weren’t (yet) wired up properly. :)
