>>14282009I don't think it's that big of a deal. There is no CO2 fertilization almost anywhere because you need very rich soils for that to happen, it's rarely the restricting factor. The most likely thing is that the crops simply have higher yields in weight because they are sold by the kg and therefor contain more carbohydrates than 50 years ago due to selective breeding. Also I think I've seen a statistic once that even in the west nearly everyone is deficient in one or more proteins so this wouldn't make a difference except if the restricting protein dropped. The problem for people being overweigh is because of bad eating habits and not understanding the metabolic pathways of our bodies. The typical gym bro science that you have to achieve a caloric deficit would only be true if our body was designed like a machine. Its easily possible to gain less fat with a good diet then someone who eats half the calories but all from a bad diet. Afaik this guy is a physicist and a shit one at that. If you watch the video carefully you will realize he has only one source for each claim he makes. It's very unscientific and his conclusion is therefor flawed.
