> The West, typically, eats a tiny, tiny fraction of the fat it used to. And also far less animal fat. We dont do the exercise of previous generations. One study conducted around the early 1900's got ordinary people off the street to carry out a set of physical tasks. What stood out for me was the tasks and time it took to complete, todays special forces people would struggle to keep up with the physical exercise of those from the 1900's. Yes our diets have changed, we can grow food more quickly, the nutrition of the food is different to that seen in the early 1900's and arguably less nutritious but satisfies the short term needs of an over populated planet. One example, muscle density is in decline, for example US special forces know that black people have higher muscle density that Caucasians, this means Black people cant tolerate the cold or swim because they dont have the layers of fat seen in Caucasians. To the point Black US special forces have successfully sued the US military over Arctic deployments because they fail in this environment and the US military knew this before deployment. What the science doesnt tell, is Caucasians used to have the same muscle density and limited amount of fat in/on their body as seen with Black Americans generally. Carnitine is one of those chemicals which increases muscle density and its similar to Choline, main food source Beef Steak! Even ground beef has substantially lower levels, the mechanical processing removes some of it. Now this shows how science can obfuscate, look at the studies which show Choline aiding exercise and weight loss, Carnitine is structurally similar but studies on Carnitine generally dissuades people from using it for exercise enhancement. So if you didnt know about the structural similarity of the two, you wouldnt link their biological properties together. There are a lot of chemicals like this and some chemicals which are generally seen as the best FORM to take are not always available in a unadulterated form of bulk consumer amounts, but only as a consumer end product adulterated with other chemicals you dont really wont and in some cases working against the chemical in question. Diet is a very expensive absolute mind field, fortunately even the medical experts dont know it all because of their instance on injecting some chemicals still!
