It's not victim blaming to point out that "can't" isn't reasonable language. Life is hard. Doesn't mean we "can't" have some control over these variables. As I said, there are edge cases that deserve sympathy but they don't represent the bulk of scenarios.
You say this, but you also say, "Most of that 70% has enough control of these factors to reap their benefits"
70% and "most of 70%" are still either a majority or at the very least a plurality; so, I have to strongly disagree that they don't represent the bulk of the scenarios.
Is your argument that most people are lazy and should suck it up and get over it and fix themselves?
Yes most adults are extremely lazy and undisciplined.
If you do not believe this statement, ask the opinion of any medical provider you know.
- Afford to eat healthier foods. Rice, potatoes, bell peppers, onions, lentils, ground beef, pork chops, eggs, are not expensive. Time is a bigger factor but I don't buy the time argument in most cases either. Just need to prioritize.
- Improve their sleep. Most people have terrible sleep habits and there is a load of free information available for anyone who wants to make a positive change.
- Exercise. Walking 30 minutes each day yields most of the available benefit. Strength training is also available for most of the population. A secondhand kettlebell is like 20 dollars. Calisthenics are free. Some gym memberships go as low as 10/month.

If you want to phrase it that way in order to paint me as the bad guy, then sure. But I would prefer to start with not giving up personal responsibility. Not throwing our hands up and blaming externalities, big food, and big pharma. If someone has that attitude, what hope do they have? Do you not believe in empowering people? If we validate every single persons' victim card, they will eventually believe they have no control over their lives. And that's just not true.
I have been in that place myself for most of my life and for able-bodied people it is possible to get 150 minites of low-intensity excercise a week, more sun, leafy greens, a can of sardines each day, and such low-effort interventions which have a high impact on health and well-being.
My advice to those people would be to start slow and not beat yourself up about having a milkshake and such. It takes time to build habits and good habits tend to cascade and encourage you, especially when you are happier with what you see in the mirror.
