EarlyBird Diabetes Trust

EarlyBird Diabetes Trust : New research by the EarlyBird Diabetes Study claims that lack of exercise is a result of obesitynot a cause of obesity and that that physical activity has little if any role to play in the obesity epidemic among children.

London Nutritionist
Yvonne Bishop-Weston says "This is a useful bit of data. We have manic exercisers visit us all the time in our London Harley Street clinic because they just can't lose weight no matter how hard they (allegedly) try in the gym. Of course exercise is important but unless you cleverly tweak the diet you can sometimes end up not just failing to lose weight, but facing weight gain"

"It also suggests we are being conned by the food industry who are currently trying to justify their £million advertising contribution to obesity by offering sports toys having successfully thwarted FSA attempts to educate the UK public about sugar and what it does to your body."

A review published in 2009 of all trials using physical activity to reduce childhood obesity showed weight loss amounting to just 90g (3oz) over three years, and the EarlyBird study wanted to know why the trials were so ineffective. So they challenged some popular paradigms.
It is well known that less active children are fatter, but that does not mean – as most people assume it does – that inactivity leads to fatness. It could equally well be the other way round: that obesity leads to inactivity.
And this is the question EarlyBird was uniquely placed to answer. With data collected annually over several years from a large cohort of children, it could ask the question – which comes first? Does the physical activity of the child precede changes in fatness over time, or does the fatness of the child precede changes in physical activity over time?
And the answer, published recently in Archives of Disease in Childhood, was clear. Physical activity had no impact on weight change, but weight clearly led to less activity.
The implications are profound for public health policy, because the physical activity of children (crucial to their fitness and well-being) may never improve unless the burgeoning levels of childhood obesity are first checked. If this cannot be achieved through physical activity, the focus has to be on what – and how much – children consume.
EarlyBird has already shown how the trajectory leading to obesity is established very early in life, long before children go to school, and how most childhood obesity is associated with obesity in the same-sex parent.
While portion size, calorie-dense snacks and sugary drinks are all important contributors, early feeding errors seem crucial - and physical activity is not the answer.
EarlyBird is based at the Peninsula Medical School in Plymouth, and has been observing in detail a cohort of city school children for the past 11 years. Obesity is the key factor behind diabetes, heart disease and some cancers.
