Adverse Effects on Cholesterol

If dieting rebounds by weight, the weight rises slowly but surely, the rate of "good" cholesterol, them, follow suit, but down ...

The data published in the Journal of the serious American College of Cardiology from a study conducted on 485 women, 130 had a history of "yo-yo" weight (19% of women had at least three times in their lives oscillations in weight between 4.5 and 8.5 kg, 6% between 9 and 22 kg and 2% over 22 kg.). All were under examination for chest pain suggesting coronary artery disease (fatty deposits narrowing of coronary arteries nourishing the heart). On average, the "women yo-yo" had a rate of "good" cholesterol decreased by 7% compared to those with stable weight. On the other hand, larger women were also those who had weight changes of the largest and had the lowest levels of good cholesterol, HDL cholesterol, considered to play an important cardioprotective role.

And risk of cardiovascular disease potentially increased

If the mean difference in HDL cholesterol is minimal here (- 7%, 4 mg / dl), it still represents a risk factor for cardiovascular significant. There is an inverse relationship between the concentration of HDL-cholesterol and the incidence of cardiovascular complications.

This study does not allow to conclude a direct causal link between the "yo-yo" weight and CHD. It would, therefore necessary to follow a larger number of women on a time probably long enough, the arteries "fouling" fortunately slowly.
