This is a book about my radical personal health transformation: to share my weight loss journey, building muscle strength, and much more. I am writing this book upon the request of all my friends about how I did it at the age of 50.

I have delivered numerous lecturing courses and speeches to share my personal experience on this journey. Now is the time to share my story with more people globally.

Key points to know:Delicious food/ no hunger:If you want to lose weight, it is not necessary to keep yourself unsatisfied with boring food or in a state of hunger all the time. Easy exercise/ stay in the comfort zone*:If you want to build muscle strength, it is not necessary to push yourself hard in keeping up with exercise/ training which you don’t really enjoy.

It then easily can becomes a happy sustainable lifestyle with longevity. * Comfort zone definition in this book (hereafter, Comfort Zone):In this context the comfort zone is not framed negatively: fitness can be gained within your own limits and level of comfort, without stress.

I have learned it is a dynamic concept. In the short term, your Comfort Zone moves up and down according to your physical and mental conditions.

In the long term, your Comfort Zone evolves and eventually shifts to the next level. My family knew me as a lazy person and it was a family joke.

Just like many people, I would say “I wanted to lose weight” all the time but took no meaningful or effective action. All of that has now changed.

Weight loss is not something that I have to constantly remind myself about. My weight is now stable regardless of how much delicious food I eat (within my stomach limit).

During my 20s and 30s, I tried numerous methods including hard core exercise, but it did not last long. In fact, anything that is not easy will NOT sustain for long, as it is human nature to not commit to anything challenging for too long.

I am a self confessed lazy person. Historically I have never liked to do any exercise unless I had to achieve something (e.

g. , cycling around Taiwan).

Never did I even enter a gym. Now I exercise daily, and I attend gym workouts every other day.

Anything that is not interesting will not be pleasurable to me. It is human nature.

I believe that there are many reading this with similar thoughts/ experiences. That’s the purpose, to share with you my own journey: an easy to do strategy as “happy” solutions in this book.

Find your own Comfort Zone; make progress towards your own health and fitness freedom. Dr.
