Not if you're diabetic. Then it's just a swan dive into the cesspool of sugar spikes and a day of testing and balancing.
I never eat breakfast except for the occasional 6 oz. glass of V8.
It doesn't need to be that way. If you're type 1 diabetic, they have a pump with continuous monitoring and adjustment. If you're type 2, then it's time to get restored into a non-diabetic state.
I can go without it but eventually I develop a sick headache which lasts a couple of hours. I rarely drink caffeine so it is not a caffeine headache. My Mom is the same way if she doesn’t eat breakfast. If I can tough out the headache I really don’t get hungry up until 1:00pm or so.
I went on a low carb diet last winter and avoided carbs religiously except for a piece of cake for my wife’s birthday. I had a doctors check up and despite two months of low carbs, I lost no weight. He did blood work and my ketones were off the scale and he called me back in to recheck those they were so high, still now weight loss after three and a half months. I had been on a low carb diet when I was younger and lost 75 lbs and kept it off for fifteen years. This one has me baffled.
