From what I have learnt so far is this:
1. Time restricted feeding works way better than Keto. Although Keto can be a good start. Keep eating window between 4 to 6 hours, max.
2. One actually has to limit Fructose, instead of Glucose, in order to improve T2DM, get faster weight loss, and overall health. Ideally, the Fructose consumption should be restricted to less than 20 grams per day.
3. Nothing works if one doesn't a) Sleep early, b) Doesn't move much the entire day.
Do 10000 steps, walk for 1 hour, 5 miles etc are all misleading. One can do all of that, but, one just have move a lot and sit less. That's all.
4. Avoid grains at all costs.
5. Look for any fat which is either Saturated fat or mono Unsaturated fat and doesn't let one's Omega-6 to Omega-3 fatty acid ratio to go higher than 4:1 in anything consumed. Hint, read labels and learn how they hide poisonous ingredients in them.
5. Avoid "forever chemicals" (search internet for this term) at all costs. I have to admit, its not easy to do that. Nevertheless, try hardest.
6. Nothing works if one doesn't manage stress.
That should suffice.
