In 2011, sprinter Usain Bolt was disqualified from the World Championships 100-meter finals — a race he had dominated for years — because he left the starting blocks early.

A harsh rule change made the year before meant that just one false start (some called it “sudden death”), instead of two meant disqualification.

When obesity starts out early, it can mean disqualification too — this time from a healthy life.

A recent study from Case Western Reserve University School of Medicine in Cleveland looked at more than 2.6 million cases of obesity-related cancers, as well as 3.4 million cases of non-obesity-related cancers in the U.S.

The research revealed that rates for six of 12 cancers related to obesity — colorectal, uterine, gallbladder, kidney, and pancreatic cancers, and multiple myeloma — have significantly increased for adults under 50.

In fact, the rates for those cancers among millennials (those born 1981-1996) is about double the rate for baby boomers (born 1946-1964) when they were the same age.

Excess weight is a known carcinogen, fueling inflammation, feeding cancer cells, and accelerating their growth. When younger people are overweight or obese, it gives fat more time to fuel cancer.

The takeaway? If you or someone in your family is an overweight child, adolescent, or adult under 50, it's possible to reclaim the future by eating a whole-food, plant-based diet and getting as much physical activity as possible.

Besides cutting the risk for early onset of obesity-related cancers, you'll be creating protection from cardiovascular disease, dementia, and diabetes.
