Found an inspiring blog with some solid keto diet advice. I especially agree with this:

One of the most effective tricks during a diet is routine. Eat the same meals over and over or plan your meals ahead for the whole week. I’ve found it effective to pre-make dishes on Sunday and have them ready for the week. That makes it incredibly easy to stick to the diet because I avoid thinking which means I avoid creativity and creativity requires decision making which leads to hard choices. Just avoid the hard choices and have it all planned and some of it ready to grab and go.

The Basic Keto Diet, a page on Mike Maunder’s blog, has about everything you need to understand the ketogenic diet principle, plus a list of foods and menu plans. It’s thorough and inspiring.
