Adults should be getting at least 2.5 hours of exercise each week, and children a whole hour per day.
But globally, one in four adults and eight out of ten adolescents aren’t active enough.
Calorie-dense processed foods and growing portion sizes coupled with pervasive marketing lead to passive overeating.
And scarce resources, and a lack of access to healthy, affordable foods creates an even greater risk in disadvantaged communities.
Yet, our genetic makeup also plays a part.
Studies on families and on separated twins have shown a clear causal hereditary relationship to weight gain.
Recent studies have also found a link between obesity and variations in the bacteria species that live in our digestive systems.
No matter the cause, obesity is an escalating global epidemic.
It substantially raises the probability of diseases, like diabetes, heart disease, stroke, high blood pressure, and cancer.
It affects virtually all ages, genders, and socioeconomic groups in both developed and developing countries.
With a 60% rise in child obesity globally over just two decades, the problem is too significant to ignore.
Once a person is obese, the climb to recovery becomes progressively steeper.
Hormonal and metabolic changes reduce the body’s response to overeating.
