Fantastic! The best way, honestly! I get so fed up with the plans people unwittingly pay for because they think they’re better than actually learning and doing research. Easier maybe, more effective? Unlikely.
50g is a good starting point but unless you’re extremely active you’re unlikely to get into ketosis at that level, most are guaranteed ketosis at 20g and some choose to increase from there once adapted.
Best to lose any sweeteners if you’re able to but if you need them as a crutch for a while to help you stay on track, use them. You may even be one of the lucky people who had no problem using them regularly, but be aware of them as a potential issue.
Eat to hunger, carbs below 20g as stated above, fat and protein to keep hunger away. Do not deliberately limit calories, do not make yourself hungry.
Supplements… extra salt on your food, maybe magnesium.
Ketosis is a normal function of the body, just many “bodies” have forgotten how to use it due to being flooded by carbs. But yes, if you wanted to go back to burning glucose you could do that, but even better, if you get properly adapted to keto you could have the best of both and if you wanted a carby treat here and there it would be unlikely to be an issue (unless you have serious metabolic issues or sugar addiction - if this is the case, please stay keto for the sake of your health).
