To Be Joyful, To Be Young

What really works to make sustainable changes in diet and lifestyle? It’s probably not what you think. In the past 30 years of conducting clinical research, I1.(learn) that real keys are pleasure, joy and freedom. Joy of living is sustainable; fear of dying is not.

Why? Because life is to be enjoyed. There’s no point2.(abandon) something you enjoy unless you get something back that’s even better, and quickly. When people eat more healthfully,3.(quit) smoking, and manage stress better, they find they feel so much better, so quickly. It reconstructs the reason for making these changes from fear of dying to joy of living.

Contrarily, some of the women who felt relaxed 10.raising a disabled child had more normal-appearing telomeres.

In other words, if you feel stressed, you are stressed.
