30 Minutes of Exercise Reverses
Pre-Diabetes
Just adding a few hours of exercise each
week cuts the risk of developing a pre-diabetic
condition known as insulin resistance syndrome,
even if they don’t lose weight.
As the population is eating more and exercising
less, increasing numbers of adults and children
are developing the syndrome, which results when
a person loses the ability to use insulin effectively.
The syndrome can develop into type 2 diabetes
and increase the risk of heart disease if left
untreated.
To investigate whether physical activity influences
the risk of insulin resistance syndrome, researchers
followed 18 sedentary men and women for six months.
Participants exercised by walking for 30 minutes
between three and seven days a week and were told
not to change their diets or body weights.
At the end of the study, researchers examined
insulin sensitivity and levels of blood fats,
such as cholesterol.
It was found that exercise with no weight loss
increased insulin sensitivity.
According to researchers, even modest amounts
of exercise, without weight loss or loss of abdominal
fat, can improve indicators of glucose and fat
metabolism among inactive, middle-aged adults,
a group that is particularly at risk for developing
type 2 diabetes.

YOU KNOW: New European Guidelines
for managing hypertension?
Blood pressure in patients with diabetes should
be lowered to <130/80mmHg, and evidence of
microalbuminuria in patients with type 1 and type
2 diabetes is an indication for antihypertensive
treatment, according to recently published guidelines
by the European Society of Hypertension and the
European Society of Cardiology. Journal of Hypertension
