Confession: I have put on 30 kilos (4.7 stone) since I started the PhD and I now have a BMI of 36. Don't worry, I know I am fat, but how did I let this happen?. My sedentary lifestyle doesn't help, I spend too much time in front of the computer working on the thesis. Stress means that I overeat - but this is not an excuse. My doctor sent me to see a dietician, as he thinks that my extra weight affects my health (true story, some of you may remember my recent posts about my bad health). I now diet and I have started seeing the first positive results. I have also made time to swim at the local swimming pool. I go there every day, swimming for at least half an hour a day, no matter what. At least confessing that I have a problem is better than pretending the problem doesn't exist.
