Does anyone find it odd that no obesity expert anywhere in the World can plausibly explain what caused the global obesity/diabetes epidemic? In my view, the most likely explanation has to do with changes in animal husbandry. Excerpt from Page 56 of 'Omega Balance' by Australian zoologist Anthony Hulbert, PhD (2023) "The contribution of “pork and poultry” to animal-sourced foods was 20 percent in 1961 and 41 percent in 2018…Between 1961 and 2018 there was a dramatic worldwide increase in the supply of fats from sources that have very low omega balances. Fat from “pork and poultry” was greatest in North America for the entire 1961-2018 period, while for Australia and South America, the contribution from “pork and poultry” was the World average level in 1961 and showed the greatest absolute increases (about 16 g) over this period to be similar to North America and Europe in 2018. There was negligible change in Africa over this period."

Here's a clue as to what made the food supply obesogenic. "It is true that the vast advancement in technological developments has led to a reduction in physical activity worldwide, but as obesity now involves infants and the populations of developing countries, this obesity pandemic cannot be attributed to this alone. In addition, laboratory and other domesticated animals have also been subject to the increased prevalence of obesity, despite having largely unchanged living conditions for many years." https://www.intechopen.com/chapters/41405

Steve Blechman explains why the Mediterranean style dietary approach consistently produces favorable results. "The Mediterranean diet is low in arachidonic acid and rich in healthy fats such as monounsaturated fats found in extra-virgin olive oil (EVOO), nuts and omega-3 fatty acids from fish, which has been shown to lower the risk of inflammation, heart disease, cancer, diabetes and obesity, and other degenerative diseases." dvancedmolecularlabs.com/blogs/news/new-red-meat-study-controversy

Another clue as to where the problem lies. "Endocannabinoids and their G-protein coupled receptors (GPCR) are a current research focus in the area of obesity due to the system's role in food intake and glucose and lipid metabolism. Importantly, overweight and obese individuals often have higher circulating levels of the arachidonic acid-derived endocannabinoids anandamide (AEA) and 2-arachidonoyl glycerol (2-AG) and an altered pattern of receptor expression. Consequently, this leads to an increase in orexigenic stimuli, changes in fatty acid synthesis, insulin sensitivity, and glucose utilisation, with preferential energy storage in adipose tissue." https://pmc.ncbi.nlm.nih.gov/articles/PMC3677644/
