Remember the "98-pound weakling"ads? You know, the skinny guys who always got sand kicked in their faces at the beach? Remember them?
I know someone exactly like the poor, skinny guy in this old ad. He's not very tall and extremely slender. He's very typical of the ethnic group to which he belongs.
Last year, he decided he wanted to bulk up and was therefore cutting down his carbs and upping his protein consumption. His appearance didn't change a bit.
About two months ago, he announced he had started a new and demanding exercise program to make himself more muscular. Last week, I asked him if he was still doing the program. Yes, he said. Though it was very tough, he was doing his workouts religiously and had been doing so since he had talked to me about it two months ago. Then he said wistfully that he had neither gained nor lost any weight. And to my eyes, he looked exactly the same as he had before starting the program: like a "98-pound weakling".
The moral of the story: It's ["it" being changing your body] tough for them [the naturally thin] too. Eat well and enjoy physical activity but don't expect to change from a peony bush into a sequoia. You are who you are.
