This is an extended version of the much heralded and talked about book Carnivore Fit. In addition to information in Carnivore Fit which looked at benefits of eating meat and exercise. I add in the potential dangers of eating grains, sugar, seed oils, fruit and vegetables. As well as building in further information on how to exercise on Carnivore. Including a 6 month marathon training plan. From my research, it is pretty clear to me that we have thrived on fatty meat for millions of years. Eating plants, was a starvation protocol until we found a source of meat again. However, nowadays we are trying to thrive on the starvation protocol, and trying to prove meat is unhealthy. This is a real shame as you can see modern diseases like obesity, diabetes, dementia, autoimmune, allergies, heart disease, and cancer are skyrocketing. The mainstream is trying to blame meat for this. However, how can modern diseases be caused by ancient food? Instead look at what people have started to eat in the last 100 years. For example, more grains, more sugar, and more vegetable seed oils. That is where the blame lies. Remember the more a food is processed the more profit is to be made from it. There is very little profit to be made from a Carnivore Diet.I do think the Ketogenic Diet has a real shot at becoming mainstream, as it includes fruit and veg. This fits into a narrative a lot of people are comfortable with. Plus there are ways to profit from it, like Keto cookies and protein bars.Keto is also very effective, so the wisdom of the crowds will see the benefit in Keto. This will benefit the carnivore diet too, as a lot of people who do Keto end up trying or at least think about trying carnivore at some point. There is not much of a leap from Keto to Carnivore, whilst there is a giant leap from a mainstream diet to Carnivore.If you look at the trends though, we are becoming more and more plant based. This will likely continue. The world will get sicker, and the mainstream will continue to deflect blame. They are struggling to prove the nutritional science behind this push. Access to studies and data is too readily available nowadays. So in 2019 you will see them try and push the environmental and moral issues. These are just as bogus, but it might give them another 10 years of deflection. We all know deep down though that burping cows are not the real problem. The burning of fossil fuels is the elephant in the room. How can I, who only eats British meat be a bigger environmental burden than someone who eats bananas which need to be flown over from South America.I believe Carnivore is the base Human Diet, and the vast majority of people would do very well on it. However there are variances in that spectrum, but for the most part I think the following 3 rules would be a change for the better, for most people.Rule 1 - do not eat anything invented in the last 150 years, or needs to be made in a factory.Rule 2 - Treat anything created in the last 15,000 years with suspicion. Only eat it if you know for sure you can tolerate it, and only when in season. Even then you don't have to eat it if you do not want too.Rule 3 - Freely eat anything that was available all year round over 15,000 years ago. Basically meat, fish and eggs (although some people do have issue with eggs, so test that out too).The younger or healthier you are the more you can likely tolerate things in rule 2, if you want.The older or unhealthier you are then you would likely just be better off sticking to Rule 3.Or think of it like your health is an elastic band. The harder and longer you pull at the elastic band with a poor diet the more likely it is to snap = disease. The longer and thicker your elastic band is the more wiggle room you have. Problem is you have very little idea what size elastic band you have.
