It’s based upon everyday, modern foods that mimic the food groups of our hunter-gatherer ancestors – essentially what humans have evolved to eat & process.
You basically increase your intake of protein, fibre, monounsaturated and polyunsaturated fats with balanced Omega-3 and Omega-6, whilst lowering your intake of carbohydrates, replacing them with non-starchy vegetables.
You’re still able to eat oils provided they’re natural – so coconut & olive oil are fine. Fish, meat, poultry are all musts – provided they’re fresh, grass-fed and not at all processed! Fruits are also fine, but you have to be aware of the ones which are higher in fructose – you can still have them, just don’t gorge yourself. Nuts are also fine, again, in moderation.
