What they seem to always fail to note is that when they're put on a low cal diet, they're also reducing carbs significantly, since they're automatically cutting out huge swaths of dietary carbs when they're cutting fat cal intake, just by cutting out things such as cake, chips, cookies, and candies such as milk chocolates, etc. Carbs might be cut even further by people who see no point in eating breakfast toast or a roll with dinner, if they need to forgo the butter to reduce calorie intake, drop the deep fried foods (breaded/battered) and french fries to save cals, and switch to salad for lunch, rather than avoid mayo on their sandwich.

Will that tactic reduce carbs enough to go off all diabetes meds? That's the problem - depending on your eating preferences, you can still keep calories fairly low if you go very low fat to save calories, and eat not much of anything other than carbs, still ending up with far too many carbs for your body to handle. Depending on how advanced the diabetes is, you might be able to get away with that tactic though.

That's assuming that you can handle feeling like you're starving every day for the rest of your life, due to the severe lack of dietary fats, and don't mind being limited to egg whites, low fat fish, fat free chicken breasts, and fat free milk products for your protein.

All that sounds miserable to me - I'd much rather forgo the carbs than the fats, and have long lasting energy. But as Dr Kar said, it still needs to fit in with the individual.
