Reduced intake of calories plays role in obesity prevention, scientists say

Scientists at the University of Cincinnati have discovered a protein called ERK that may be responsible in causing obesity. Along with p62, a protein thought to suppress the production of fat cells, it may be involved in what the Mayo Clinic considers a "growing epidemic."

Obesity affects 1 in 3 Americans and is ly becoming a global problem. In addition to causing heart disease, diabetes and cancer, it can also reduce life expectancy.

Most cases result from an excessive caloric intake, especially from a diet consisting of fast food and oversized portions. Although other factors may come into play, such as genetics, age and family history, a healthy diet is quintessential in the prevention of obesity.

The Mayo Clinic suggests reducing the caloric intake in order to begin losing weight each week.

Fruits and vegetables will satisfy hunger with fewer calories, compared to high-density meals like processed foods and desserts. There are also calorie-reed diets, such as the HCGWeight Loss Plan, that can help educate people about incorporating life-long healthy eating patterns.

Keeping a food diary may also be beneficial in pinpointing bad habits such as skipping breakfast and consuming too much junk food.

In time, a carefully controlled diet may help prevent obesity and promote a better, healthier lifestyle.
