Mr. Fitzpatrick has given much attention to his "Weight reduction" (减轻体重) programs. Just last year,
for example, when he was the main speaker at the company dinner, he said he put on twenty pounds instead
of losing thirty he promised he would.
The year before that, he joined a health club. He exercised every day and ate less food. At the end of three
months, however, he began making excuses about why he couldn't go there more often.
After the health club failed to work, he joined Weight Watchers but stopped going because he was the only
man there. And he hated following any of the diet programs. Fitz's latest idea is to join a walking club to "walk
off" the weight.
