Blah blah blah, that's the old stuff. But did you know I'm a fairly old keto enthusiast?
Usually at the height of 1.78m, I weighed 85kg. At the peak of my existence (hihi), that was like, 97kg about 3-4 years back after arriving back from the Middle East (amazing food turned into energy storage). Well, I tried once for a month: lost 15kg. Then due to varying duties I could not stick to the regime very often but I'd recurrently dip and raise. My longest run took a 100 days, when I wasn't so strict and the most recent attempt got me down to 71.5kg (over 10 kg lost in +7 weeks). Australia is a bit more friendly to ketoers/low-carbers nowadays, since you can find substitute for most, even: cakes, bread, pasta, ramen, sodas and honestly anything and everything (and it's so funny to buy stuff that literally has nothing in them, except being sort of a placebo).
But hey, a dip from 97 to 71.5 within a spectrum of a few years is fairly impressive, no?
(treating 72-75 for myself as a sweet spot)
