I'm an obese dude. I know a whole lot about nutrition and exercise. I cook for myself. I'm pretty active. Lets take a look at these recommendations:
* actions to support healthy practices from day 1, including breastfeeding promotion, protection and support;
I was breast-fed as a child. I am a big chonk.
* regulations on the harmful marketing of food and beverages to children; school food and nutrition policies, including initiatives to regulate the sales of products high in fats, sugars and salt in proximity of schools;
I ate school lunch and only school lunch as a child, which was certainly not good, and was almost certainly never adequate in terms of nutrition for my early 6'+ frame. I am a big chonk.
* fiscal and pricing policies to promote healthy diets;
And this means what? I am a big chonk.
* nutrition labelling policies;
It's important to have nutrition labeling. Let's say I'm on a blood thinner that's sensitive to vitamin K due to genetic issues. Will that be part of the labeling? No? Well OK then. Not very helpful. That said, I can read calories and the macros. Nevertheless, I am a big chonk.
* public education and awareness campaigns for healthy diets and exercise;
Look, there have been public education and awareness campaigns for healthy diets and exercise for decades or even centuries. I personally needed to participate in the President's Physical Fitness test in the US, which I understand has been present since (checks notes) ah, the 1800s. Despite participating, I am a big chonk.
* standards for physical activity in schools;
I fully participated in gym classes to the best of my ability. Even my PE teachers were impressed with my efforts, despite the fact that I was a big chonk. I have remained active, and likely more so than average, in adulthood. I am still a big chonk.
* integration of obesity prevention and management services into primary health care.
Indeed, I have had many doctors make me feel bad about being a big chonk.
Look, none of this matters. I'm a 6'4" big chonk that '70s medicine was totally unprepared for, and there's more of us now. Something is going on that is making us big, and is making us hungry. I don't know what it is. I've spent my life trying to regulate it, and... education is not the answer. I know calories, I know my macros, I know nutrition, and the question here is... what can I eat that doesn't make me hungry?
The recent GLPs have helped. But there's a bigger question of why this is the way things are for an increasing number of us.
