Hello, exercise doesn't necessarily cause you to loose weight. I lost my wife in 2013 and just wasn't doing anything, but decided a couple years later to improve my type 2 diabetes and loose weight. I came up with what I call meal plans, not a diet. I kept records of my weight, blood pressure, and blood sugar for a period of 3 months. I lost 50lbs and was able to stop taking insulin. I ended up weighing 175lbs. I published a book on amazon about my effort. It is called "A Meal Plan for and Overweight, type 2 diabetic. author Bill Brinegar. Well I was still taking metformin, and blood pressure medicine, so I decided to improve everything further. I did research and decided to do Intermitting dieting and only have low carb meals. So now I weigh 150lbs and don't take any Blood Sugar or Blood pressure Medicine, and I have good A1c and blood pressure averaging around 117/ 70. It really works.
