Ketosis

I tried this several years ago and was getting bad headaches. But I was going about it poorly. I'd like to try it again, go a few days once a month at nearly zero carbs.

• Avacado 2%
• Spinach 1%
• Asparagus 2%
• Fish 0%
• Cheese 0%
• Egg 1%
• Almonds 4%

Good news, coffee is 0.

The general target seems to be 20g or less.
