20-Year Prospect
There's nothing like a doughnut for breakfast in the morning...although you, party pooper, would rather take a hard punch to the spleen than let that much sugar and lard slither down your gullet.
That's because you know exactly what doughnuts and all those other fun, delicious, and very not-nutritious foods do to the human body. Thanks to our consumption of junk calories, more than one-third of American adults are obese and more than one-third of American kids are obese or overweight.
Getting rid of all the excess weight on the collective American corpus is going to take time and effort—and a well-balanced diet, which is where you come in. Because nutrition plays such an important role in weight loss and healthy weight maintenance, your career is definitely going to be around for the next couple of decades.
In fact, the Bureau of Labor Statistics projects that the employment of dietitians and nutritionists will grow by sixteen percent between now and 2024 (source).
Keep up the good work, cupcake. Mmm, cupcakes...
