There are some people who enjoy working out and restricting their diet to only healthy foods, but they appear to be few and far between when normal people meet them. Their lifestyle might be one where the best part of their day is sweating at the gym then eating a healthy snack of raw vegetables, but many more people would rather lie in the sun and have something fried and crunchy for a snack. For those who need to lose weight and mass, looking for results is the only thing they are after.
It can be difficult to give up sunbathing and empty calories, but those who do their research might find there are some good tips and tricks to get them where they need to be as far as health. They might not appreciate walking on a treadmill or lifting weights, but watching the scale numbers decrease is a goal they can appreciate.
