Having been on a ketogentic diet (low carbs, high fat) for the last 5 months or so, this is in line with what I've seen.

I went on the diet because of the promise of a clearer head, as well as general health improvement. It made sense, as I'd been plotting my work efficiency with and without sugary products. The complete removal of all carbs has done nothing but improve my life.

The carb addiction component mentioned elsewhere lines up as well. At the beginning of the diet, there's a period called the keto flu that lasts a couple weeks. It's described as mental fogging, headaches, dehydration, etc. While this is also attributed to the switching of metabolic pathways (more water and electrolytes are needed daily), the effects were very similar to caffeine withdrawal.

And of course I indulged in sugar through the holidays, and found myself figuratively face down in a gutter each time ;)
