Weight gain hasn’t skyrocketed because people suddenly “gave up” on their health.
It’s because our entire food and hormonal landscape has shifted in a way the human body was never actually designed for.
Here’s what most people don’t realise:
1. Obesity has tripled in one generation!
Today, around 2.5 billion adults are overweight and almost 890 million are living with obesity.
Human biology didn’t change, our environment did. 📈
2. The low-fat era reshaped our diets.
When fat was removed, it was replaced with sugar, refined starches, gums and emulsifiers.
Foods like low-fat yoghurt, muesli bars, Up & Go, low-fat snacks and “99% fat-free” products spiked insulin, increased hunger and encouraged constant snacking.
Smart business move, I suppose 🤔
3. Ultra-processed foods dominate everyday eating.
Over 55% of food purchased in Australia is ultra-processed.
In the U.S., 54–62% of daily calories now come from UPFs.
These foods disrupt gut health, interfere with hunger hormones and make it extremely easy to overeat, therefore leading to weight gain and numerous health conditions. 🍟
4. Most people eat 6–10 times per day without realising it.
Coffee with milk, a muesli bar, a handful of crackers, kids’ leftovers, a yoghurt, a café treat every small bite still spikes insulin and stops fat-burning. ☕️
5. Modern stress, poor sleep and shifting hormones make appetite and metabolism harder to regulate.
Higher cortisol, disrupted sleep, reduced insulin sensitivity and perimenopause all shift how the body stores fat and responds to food. 🌙
When you put all of this together, refined carbs, UPFs, constant snacking, chronic stress, disrupted sleep and hormonal changes, our metabolism is operating in a completely different world compared to 40 years ago.
It is extremely important to look at weight gain, and the struggles to lose weight, from a holistic approach.
The whole “eat less, move more” concept often does not work.
It’s about understanding what’s really driving weight changes so you can finally make decisions that work for your own body! 💛
