Losing weight is like running a marathon. According to many experts on running, there are some things that take precedence as preparation for success, such as
customizing a training plan
tracking your progress
building up endurance and stamina
You can train as a weight-loser too. You can make a plan totally suited to you. You can try it out, beginning slowly, and see how you are progressing. If it' s going well, continue with this plan. If your progress is impeded, see if you can alter your plan. Start with small changes and build up your ability to do it. That' s how to get the endurance you need.
Can you think of more parallels between preparing for a marathon and preparing to run the weight-loss track?
Both are serious, worthwhile endeavors, and requiring a good deal of thought, planning, and practicing.
