It is a huge myth that type 2 can be prevented. Genetic play a massive part in it.
This is a huge bugbear of mine.
People look down on people with type 2 like we'll it's all your fault etc..
You REDUCE your chances by eating well and exercising.
Evening you life a perfect life you can still develop it.
Take my husband family out of the 9 siblings 8 have type 2 with 6 of those need insulin injections. The 9th one is only in her 30's so has a high chance of getting it.
Some of them are and have always been fitness addict.
Than the if is my mum who while having a risk due to genetics. (2 sister have it) her lifestyle increase her risks dramaticly.
