Fat of the matter

Weight is a weighty issue these days.
“You have put on weight,” “You have lost weight,” have become common usages when we meet acquaintances.
When I met a friend yesterday, she looked hassled. “The doctor has asked me to shed weight or face trouble,” she said.
“OK, join the gym immediately,” I suggested.
“Are you mad? I am 44 and have never stepped into a gym,” she said.
“Go for dieting.”
“You know my appetite,” she retorted.
What about yoga?
“My God. I cannot bend this way and that way.”
“Good, I will give you a solution. Try walking one hour every day,” I said.
“That I tried last week,” she replied.
“Great.”
“What great? Every time I returned home I became so hungry I ate double the normal. It’s all back to square one.”
“Bye, bye,” I vanished from the scene.
