Gβday everyone,
Over the past few decades, Iβve spent much of my career looking at the link between obesity and type 2 diabetes β and the real-life ways we can turn things around.
A while back, we ran a randomised controlled trial here in Melbourne comparing two approaches for people recently diagnosed with type 2 diabetes:
1οΈβ£ Traditional lifestyle and medication
2οΈβ£ Laparoscopic adjustable gastric banding (or βlap-bandβ surgery)
The results were nothing short of remarkable. After two years:
βοΈ 73% of those who had the surgery went into full diabetes remission β meaning normal blood sugar levels without needing meds.
βοΈ In the lifestyle group? Just 13% achieved remission.
βοΈ On average, the surgical group lost over 20% of their body weight.
We werenβt surprised to see better blood glucose numbers, less insulin resistance, and fewer needing diabetes meds. What did surprise us was just how strongly weight loss itself predicted diabetes remission β not necessarily the method, but the amount of weight lost.
π‘ In fact, if someone dropped more than 10% of their body weight, their chances of remission skyrocketed β no matter their age, s*x, or starting weight.
π§ So whatβs the take-home message?
For people living with obesity and early-stage type 2 diabetes, meaningful weight loss β especially through surgery β may offer a real chance at remission, not just better control.
This isnβt about vanity or quick fixes. It's about evidence-based medicine and giving people back their quality of life.
We still need larger and longer-term studies β but these results were a powerful wake-up call: maybe itβs time we start thinking about weight loss surgery as a front-line therapy, not a last resort.
