On the other hand, there exists evidence that hardcore keto just for weight loss doesn’t outperform non-ketogenic low carb, and you can even lose weight successfully on low fat, but these things are BIG whichever you choose:
1) lose all ultraprocessed and junk food, regardless of macros
The results from low fat and low carb groups are approximately the same in long term outcomes, as long as both groups stop consuming junk food.
2) fix your sleep hygiene ASAP
3) get movement during the day
4) stop eating before evening
About 3): my N=1 confirms that brisk walking even for 30 minutes does wonders to my blood glucose levels. There are also studies that confirm that long walks do lots of good and that it’s not just me. Hitting the gym is optional, and you can invent reasons to spend an hour a day or two walking.
I’m positive that keto should be more for those who find it improving their mental state and diabetes; general population, not so much.
