Weight loss responders?

Dr Jason MR Gill and team from the University of Glasgow studied a group of overweight or obese sedentary women for 8 weeks to see how they would respond to government-recommended levels of exercise.

They found that one third of the women were responders – losing the amount predicted by the exercise, or more.

Two thirds were non-responders. Even though some of these lost weight, it was by less than the amount predicted from exercise, and this group as a whole put on weight.

Both groups benefitted from a significant reduction in waist circumference. Although this may suggest a redistribution of fat away from the dangerous area of the abdomen, fat distribution was not checked in the study.

Both groups increased their energy intake by eating more. The difference in the extra amount eaten by responders v non-responders was not significant.

Over the 8 week period, despite starting from low fitness levels most women rated the exercise regime as enjoyable. They were working for the government-recommended 150 mins per week, at roughly 75% of their age-predicted maximum heart rate. At this level, stickability (the rate at which the women completed the exercise routine) was 100%.

Other important health-related measures, such as maximum oxygen uptake, showed significant improvement.

Gill’s study also shows who responds and who doesn’t, how you can make a good prediction of this in advance, and how you can test if this is working for you without waiting for 8 weeks to see. We’ll cover all of these findings in a forthcoming Internet workshop on high-success weight loss.
