I am in T2 category because that's what I am! I ate the wrong foods because that's what the recommended diet was for many years - low fat, low calorie. That's a bad lifestyle choice! I was active until I suffered from depression and ME, so I was forced to become 'lazy'. I went to my GP for help to lose weight. The diets I was given didn't work. One of them was the GI diet. I put on weight on it and had to give up after 2 weeks because I couldn't afford to put on any more pounds. At that time I had been gaining 7 pounds a year. I gained 8 pounds in just 2 weeks by following the GI diet and the recommended portion sizes.
My husband went to the same GP about a minor illness and was told 'Keep on doing whatever you are doing' So he did. He ate 6 Snickers bars that night 'just because they were there' He is slim and not T2. My diet has always been healthier than his and I exercise just as much as him, sometimes more, yet I am the one criticised for how I look.
T2 is also a condition where our bodies don't function properly.
