What can we add to our post-workouts for better fitness and for stress relief? Surprisingly, one answer is blogging.

Human beings like habits, as a rule. Good or bad, habits allow us to predict the future — if I do this exactly as I did yesterday , I know what will happen. Habits equal proven outcomes. Habits provide routine, and for us, routinely provides security.

Can leptin and ghrelin levels provide some explanation for the ups and downs that dieters experience? And could this relationship be more complicated than we expect? The title kind of gives the punch line away. Weight regain after a diet-induced loss is predicted by higher baseline leptin and lower ghrelin plasma levels.

J Clin Endocrinol Metab. Epub Aug Researchers put over obese and overweight men and women with an average BMI over There was no change in physical activity, just less food. Researchers measured body weight, body fat and waist girths. They also took blood samples. Measures were taken before dieting week 0 , right after the dieting week 8 , and 6 months later 32 weeks. They lost an average of 1. This may seem self-evident and not that interesting… until you look at their blood samples.

Somehow losing weight is correlated to drops in leptin and insulin. Figure 1 below compares the differences between the two groups. Six month after the diet ended, this split continued. About half the group lost more weight; half the group re-gained the weight they lost.

Blood levels of leptin and ghrelin were correlated to weight loss or regain — and this effect often depended on sex. Figure 2 shows the changes in hormone levels between weight maintainers WM and weight regainers WR at the start of the diet 0 weeks , end of the diet 8 weeks , and 6 months later 32 weeks.

WRs are indicated by the red lines; WMs are the black lines with circles. The biggest hurdle dieters face is weight regain — and dealing with it is a daunting prospect. Appetite is controlled by a host of complex, interacting factors. This study suggests that the hormonal mechanisms may be different for men and women — and among men and women. However, there were also important differences within groups as well.

Some men lost weight while others regained it. Some women lost weight while others regained it. Not so in this study. This suggests that in obese people, leptin and ghrelin signals may not always work in ways that we expect. Obesity can disrupt normal appetite signalling. Metabolic endocrinology appears to be only slightly more complicated than a nuclear reactor and brain surgery combined.
