If you have ever felt you should be doing better with food, this one is for you.
There is a concept in public health research that does not get talked about enough outside of academic circles, and it changes the whole conversation when you understand it. It is called the obesogenic environment.
What it actually means
The term was coined by Australian and New Zealand researchers in the late 1990s, led by Professor Boyd Swinburn. It describes the sum of influences in our surroundings, opportunities, and conditions of life that quietly promote weight gain and make healthy choices harder.
It is not about food alone. Think about a normal week. Desk jobs and screens that keep us sitting for hours. Cars and lifts instead of walking. Suburbs designed around driving, not movement. Workplaces that run on biscuits, takeaway lunches, and back-to-back meetings with no real break. Supermarkets stocked with ultra-processed food at eye level. Social lives built around food and drink. Sleep cut short by notifications. Marketing aimed squarely at women that flips between "treat yourself" and "shrink yourself" depending on the season.
Each of these on its own is small. Stacked together, across a lifetime, they create an environment that makes the unhealthy choice the easy default and the healthy choice a constant act of effort.
None of that is a personal failing. It is the water we are swimming in.
Why this matters for the way we talk to ourselves
Most diet and lifestyle advice treats the problem as one of motivation. Try harder. Want it more. Be more disciplined.
But the research suggests that personal motivation, however strong, is fighting an uphill battle against a system that was never designed to support it. The obesogenic environment is not a moral failing of the individual. It is a structural feature of modern life.
This reframing matters because it changes the goal. The question stops being "how do I find more willpower?" It becomes something more useful: "how do I build a few defaults into my life that do not require willpower at all?"
What this looks like in practice
Working with the environment, rather than against it, comes down to a few small structural changes that quietly do the work for you.
-
Pick one daily non-negotiable that runs on autopilot. Same time, same place, no decision required. A scoop of greens before you check your phone. A glass of water before coffee. Magnesium next to your toothbrush. The smaller and more boring, the better.
-
Audit one environment, not your behaviour. Look at your kitchen counter, your work drawer, or your handbag, and change what is within easy reach. Make the better option the lazy option.
-
Walk where you would usually drive or scroll. Phone calls on foot. The long way to the printer. Park further away. Movement counts even when it does not feel like exercise.
-
Front-load the week. Wash and chop a few vegetables when you get home from shopping. Boil a batch of eggs. Move the fruit bowl to where you actually stand. You are not relying on willpower on Wednesday night. You are removing the need for it on Sunday afternoon.
The point is not to be impressive
It is to build small, repeatable defaults that work even on the messy days. Especially on the messy days.
You are not behind. You are navigating a system that was not built for you. Working with that, not against it, is where consistency actually starts.
The takeaway: the obesogenic environment is a real, well-researched phenomenon. Most of us are not failing at willpower, we are navigating a system that quietly works against us. The fix is not more effort. It is small, structural changes that remove the need for willpower on the messy days.
