Recent commercialization and buzz is definitely new and there have been new formulations of course.
It is quite remarkable that people might think simply telling people to "lose weight" will work still, in this day and age.
Type 2 is the exact opposite. Your cells are saturated with glucose and your body literally can't produce any more insulin to stuff that glucose away. Giving insulin just forces the excess blood glucose into tissue and causes additional fat gain. The additional fat gain makes Type 2 worse. Weight loss is the treatment for Type 2.
We've kind of known this since 1915 when Type 2 was treated with fasting. Right up until insulin was discovered. [1, 2, 3]
That's why GLP-1/GIPs work for diabetes. They make you not hungry, so you don't eat, so you lose weight, and presto, no more insulin resistance.
> [...] we now understand that people with type 2 diabetes who lose significant weight and improve other factors related to diabetes can achieve remission. [3]
Fun fact.
