According to the WHO, worldwide obesity has nearly tripled since 1975. The numbers reflected in statistical data have grown as obesity sweeps 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 of the Eastern European countries made it to the list for their drinking and smoking. While Americans, Canadians, and Oceania region came out as one of the “fattest countries in the world” due to their high obesity rates.

Overview: According to research, Afghanistan was reported as the healthiest country with a 2.7% obesity rate. On the other hand, Samoa is ranked first for obesity with 41.6% of the population being obese. The Czech Republic is the unhealthiest country in the world, mainly due to their alcohol consumption. The United Kingdom came 19th on the list overall as Britons are the 9th heaviest drinkers. Canada was placed 14th for its 30% obesity rate.
