Healthy Girls Don’t Need Fast Weight Loss Diets?

My grandmother came from a culture and generation which prized women with a little extra meat on their bones.  They didn’t believe a healthy girl needed to diet.  But my generation doesn’t prize overweight girls so five minutes after I left home I found a fast weight loss diet and fitness plan that helped me shed thirty pounds.  Everyone now compliments me on my figure and healthy looks except Grandma.  She continues telling me I need to eat because men don’t like a skinny girl, even though I’m engaged.  When I mention this to her, she says my fiancee is also too skinny and tries to feed him.
