Hi everyone, I am 66 years and have been prediabetic for about 4 years with FBG readings gradually worsening. I am relatively fit and active and eat pretty well (sugar free/ lowish carb). My GP tells me I am underweight - (BMI 18) - and that I should try to put on weight. I eat heartily already and couldn't eat more and so am now doing some daily exercises including with weights in an attempt to increase my muscle mass and hence BMI. But to get to my point what I want to know is would more exercise such as 30 mins energetic walking every day help increase my insulin sensitivity? Obviously I mustn't lose weight and am curious to know if exercise has been shown to be helpful in type 2 diabetes in people who don't have any excess weight to lose?
