The Change of Hormones
When we're out of our normal routine, our hormones change. The best example of this is when you're flying and you have two periods in one month instead of the usual one. If your hormones are changing it could be the result of a number of things, from menopause to a change in cortisol levels. Sometimes it's as simple as not being in tune with nature, with what we're meant to do, that alters our hormones.
A certain combination of appetite hormones, leptin and ghrelin, appears to predispose some people to weight gain following a diet. An upcoming issue of the Journal of Clinical Endocrinology & Metabolism features a story on the connection between appetite hormones and long-range weight loss complications. The study included 104 obese and overweight men and women and measured each participant's body weight and fasting plasma levels of ghrelin, leptin and insulin. Those with higher leptin and lower ghrelin levels before dieting were more likely to regain lost weight after the diet ended.
