I previously didn't know how to cook, and ate a diet of mainly processed food. I was fat, almost 300 lb.

I learned to cook, and make my own food from real ingredients. My new diet is unhealthy by most nutritional standards, meat & fat are abundant. I have lost over 40% of my body weight, and maintained that loss for 10 years.

Take from that what you will.

It's the truth. They say that certain corporate food lobbyists pay to stifle research that would change how corporations market and produce food that would fix this social issue, but it would cut into the profits of many billion dollar corporations if we collectively began losing weight.

I think the roots of this are maybe a little earlier(by a couple decades), but I agree with where I think you are going.

How in that time did portion sizes change? Consumption of soda? You also have the introduction of home tv’s then computers leading to more sedentary activities at home. Along with other home appliances making cleaning easier. What was the shift from home cooked, made from scratch meals to meals eaten out or prepared by others which tend to be higher calorie per bite? What are other factors like growth hormones in meat and dairy products? What about the shift in consumption to processed soy and corn in our diets? The rise of food like products that have been engineered to keep making us want to eat. So many factors.

My guess is overtime, foods are now packed with sodium, sugar, and fats to make it more delicious — ppl love instant gratification 😋, why cook when you can buy a whole tub of mac n cheese for $5 🫠🥲.

My other guess…people were dying earlier back then due to poorer technology in health. Couldn’t survive long enough to get to BMI of 30. 🤷🏻‍♀️

The move away from saturated fat led to slower and slower metabolism. Brad Marshall talks about this stuff alot: https://youtu.be/ZNhtHp9NcIA

It’s been longer than 200k years I’d presume. I’ve been carnivore for over 3 years . Went down this rabbit hole. Listen to Paul mason, with low carb down under.

I think there is a fairly simple explanation for first world obesity and I think it has little to do with exercise. There are two metabolic pathways in the human body. Glucose and fatty acids. Free Fatty Acids (FFA) are the way humans transport excess energy to long term storage in adipose tissue. Exercise can use up glycogen reserves in the muscle tissue, and this is replaced by utilizing blood glucose, but the proportion of blood glucose to utilization is woefully unbalanced. Insulin is released to lower blood glucose levels for two reasons, one, high blood glucose is toxic, and insulin is responsible for ferrying glucose into the cells for energy. When we eat constantly, and eat things that are either absorbed or convert to blood glucose (BG) the cellular glucose reserves get full. Insulin stays present, while the liver starts converting BG to FFA to save our lives from BG induced coma. Insulin presence in the blood block the FFA metabolic pathway. This means that while insulin is present you cannot utilize energy stored in adipose tissue.

Eating fat turns off the production of ghrelin, the hormone that causes hunger and food seeking behavior and stimulates leptin, the hormone that causes satiety. Incomplete protein is broken down at a net energy loss into glucose, which exacerbates the BG problem.

Bottom line, stop eating and drinking caloric substances all the time. Give your pancreas a rest, let insulin levels come down. Start by eating once a day for an hour, anything, and as much as you want. After a month if your not losing adipose tissue, stretch it to one hour per 48 hours. You’ll find that eating fats, fiber, and protein will provide the best satiety.

Regardless of origin beliefs, I think we can all agree that ancient man had limited access to food, sporadic access to dietary glucose, and no capacity for meaningful food storage for much of our history. The recent changes in these circumstances explain the increased obesity.

WHAT we eat changed. And the reason the WHAT changed - government subsidies.

Big government is behind most of the bad shit in the world, governments always tend toward expansion but when they’ve got a money printer that happens in absurd fashion.
