I've started keto to lose that work for home bonus weight but so many thing changed for the better. I can go on seemlinly forever without a snack and my energy levels are very stable. I also improved my cooking skills because no restaurant or food delivery around me deliver appropriate food for the diet. On the other hand I can't handle alcohol anymore. Drinking 1/3 of what I could handle makes me feel sick and hangovers are common. I might be wrong but I suppose the body uses lots of sugar to sintetize alcohol.
