Hi DJ,

Keto isn't about starving, it's about utilizing fat (ketones) instead of carbs (glucose) as your primary source of energy. You eat a normal amount of energy on keto. When on a keto diet, your body is always ready to consume fat, long before it wants to break down your muscles for energy, which is why there's less loss of muscle mass.

Having a few drinks is fine, but you have to make sure they're not sugary and high in carbs. Diet tonic or other diet sodas are good replacements, straight hard liquor, dry wines and low carb beers will keep you in ketosis. If you're trying to be on a low carb diet, you have to keep low carb. If you're keto-adapted by being keto for over a month or two, then getting back into ketosis after kicking yourself out will be faster, maybe 1-2 days.
