Meat, veg, some fruits (mostly berries) nuts and seeds.
No grains or anything processed. I don't care what colour your wheat is, steer clear. It all spikes your insulin and it all breaks down into the same=sugar.
If you are trying to lose weight keep your carb consumption to less than 100 grams per day and don't be afraid of eating the good fats and loads of protein. Multi-coloured big arse salads with lots of dark greens and other vegetables with good quality chicken, fish, etc will have you well on your way.
Uncured bacon and eggs is a great way to start the day.
Eat and eat plenty, just don't eat grains.

From the article:
We do not need grains to survive, let alone thrive. In fact, they are naturally selected to ward off pests, whether they be insects or hominids. I suggest we take the hint and stop eating them.
