Ha, that's funny. Read a book.
What makes you think they're going to eschew sweets for higher fiber foods? That doesn't make any sense.
You must be one of those people who have a high metabolism and think all fat people are lazy gluttons, right? Economics still hold. Little Debbie cakes are 1/4th the price of an equivalent number of apples. Someone who wants something sweet will on average gravitate to the least expensive option. Money trumps health.
What specifically would that book tell me? The Japanese have a diet very high in carbohydrates, especially from white rice and processed noodles. What will your book tell me is the reason that they don't suffer from the same rate of obesity as we do?

Lots of obese people are lazy and gluttonous. Some obese people suffer from afflictions that make it near impossible to change their condition. However, for most people, consuming fewer calories and burning more energy through exercise will cause them to lose weight. Or, they could just continue making excuses and blaming something other than the cause.

Equivalent number of apples? In terms of calories? What in the world are you trying to correlate here? You're confusing choices with economics. If Little Debbie cakes go up in price do you really think kids are going to all of a sudden choose to eat apples instead? Even though they've exhibited poor eating habits for years?
Someone who wants something sweet will on average gravitate to the least expensive option.
Maybe you haven't been paying attention to the incredible sales growth in the gourmet dessert category the food industry has experienced over the past couple of decades. People are most certainly gravitating to the more expensive option.
Money trumps health.
No, and despite your beliefs to the contrary, the "obesity problem" for the vast majority of overweight people is caused simply by consuming more calories than they burn. Trying to blame it on things like economics, HFCS, processing, chemicals, lack of fiber, artificial sweeteners or sunspots may be a sure way to drum up grant money but it has little to do with reality and highlights a lack of knowledge about human nutrition and physiology.
