I would never do something like this, but could it work for like weight loss? Maybe. Pretty much all stimulants are cardiotoxic. meth, DMAA, adderall, coke, hell even caffeine in high enough dosages will all be a net negative for your health.
You might could do a hack "fast" where you eat sugar in the morning and evening but keep it under 500 calories per day. Say, for example, drinking a Mexican cola in the morning and evening twelve hours apart from each other. Or fruit juice. How is this better than regular fasting? I don't know if it is, lol.
But the theory is a little bit of sugar might keep the cortisol and glucagon to a minimum provided you got good liver function and can actually hold glycogen several hours (people with poor thyroid can't).
