According to the WHO, worldwide obesity has nearly tripled since 1975. The numbers reflected in statistical data have grown as excessive body weights sweep the globe. Obesity has impacted more than one-third of the United States population alone.

Studies often look at obesity statistics to determine how countries around the globe rank for being unhealthy. However, obesity alone is not a means of measuring overall health. Recently, Clinic Compare (UK) did a study on 179 countries using three parameters:

  • Alcohol consumption
  • Tobacco use
  • Prevalence of obesity

All three of these factors have their own equally serious set of health-related risks.

Most Eastern European countries made it to the list for drinking and smoking. While Americans, Canadians, and the Oceania region came out as one of the “fattest countries in the world” due to their high obesity rates.

While alcohol, smoking, and obesity are big risks to everybody’s health, they are not all we should look out for. Our overall health is affected by a large array of factors, including:

  • Physically active vs. sedentary lifestyle
  • Sugar intake
  • Stress management
  • Sleep habits
  • Sun exposure
  • Hereditary issues
  • Work environment

But this definitely does bring to light just how serious a risk different lifestyle habits, not just excess weight, can place your health and life at serious risk.
