I recently (~6 months ago) retired from engineering. I was rather unfit and had also gained a bit of weight. I started running 30 minutes in the morning every 2nd day. It is painful in the beginning and you probably have to alternate between walking and running for a while. For the first month and half I only did 3k runs and then changed to 5k. 5 months in I can easily run 5k in less than 30 minutes and I look forward to the next run every time. The mind does play tricks and attempts to convince you to stay in bed. I have a rule that I at least should get up, put on my running clothes and if not else go for a walk. It always ends up being a run. Also I seem to consistently lose 2kg per month. I generally eat what I want, with the exception of sweets, cake, ice cream, etc.
