I retired in April. All that time to get out and cycle whenever I want---but it hasn't happened. A house and garden that needed too much input and weather that was not conducive to cycling. But since then I have lost 15lbs.
How?
Keeping very active was one thing after a great number of years on the road behind a steering wheel- or in an office in front of a computer screen--And lunches from the local bakers in the various towns I was visiting. Since April- good home healthy cooking-and eating- and that active life has meant that the lbs have have been shed without thinking.
So the idea of exercise and eating right being a problem--Will be a problem if you let it.
Good luck--Or get early retirement. It works.
