I do not believe in conspiracy theories related to food. Sure someone covers up some food debacle where a bunch of people get ecoli, yes that I would believe. The idea that an entire industry wants to keep us fat, I really do not @CaptainKirk
Most people go to school, study hard, believe what their professors say. The professors were taught that fruits and vegetables and whole grains good, saturated fats bad. Most professionals abide by do no harm, or at least not intentional harm. Their students then go out and preach whole grain, fruits and vegetables. Their patients, if you tell them that fruit is not ideal for some people look at you astounded and simply do not believe you. I had this recently with a young man I met who is on a whole food diet through a nutritionist. When you hear a nutritionist, either in their office or on a podcast say that saturated fat contributes to diabetes, it is hard even for me not to take them at their word.
Many studies have examiner bias built in. There was an article that discusses this
My impression is that it is unintentional. When studies are not correct, how can the advice be correct?
I credit reading Jason Fung for going Keto. He had extensive articles on his blog that made so much sense. Even so, when talking about saturated fat, I wondered. I still listen to as many podcasts as I can because the advice does change
As for losing weight and keeping it off, that seems to be individual. Your body has a set point and will do whatever it can to get back to it. I never realized how much that controls your weight until I talked to my cousin. She is shorter and slightly overweight, maybe could lose 15 lbs. Both her sisters are tiny, one naturally, one I think watches. She is not heavy but compared to them. She gave up dieting a long time ago. She said that she stays the same no matter what she does. If she under eats she gains it back, if she overeats, she loses it a few days later. This is not how it works for me. I would gain weight every time I ate too much. I listened to a podcast recently that said that for certain people the mechanism to regulate weight is broken once they become obese. This makes sense since I always had the fantasy that if I every got to 120 lbs or whatever, that my body would magically keep it off. Turns out most likely the opposite.
In my case I seem to get to a certain point, then I stall, then I go back up, then I get discouraged and then I quit. However, I always thought the go back up was because I was not sticking to the diet, not true, it is my body trying to get me back to my set point.
As for carts full of cereal, this is marketing but it is also your brain addicted to sugar. I did watch the Oprah Ozempic special. My favorite line was when she said that this takes away her interest in food. She always thought thin people had willpower, turns out many of them are not as food involved. The medication gives her the same power and that is why she is losing weight. A lot of this is genetic and hormones and I believe the potential for hormone problems are genetic as well. I have friends with one adopted kid and one biological kid. Their attitudes towards food and snacking are very different. The parents are heavy, the bio kid is heavy and always went for the snack drawer until his mom had to get rid of it. The adopted kid had an off switch, he would take one piece of candy and stop, he is not heavy
@Goldengirl52 metformin is an interesting and cheap medication. There are doctors in the longevity community who are studying it for potentially adding to lifespan or healthspan.
