We had our first major snowfall and very cold temperatures yesterday so we "chose" (wimped out) to skip our running group last night, discretion being the better part of valor. Hopefully, we will do better in the future. We're tough, right?
I want to bring to your attention a new Australian study published in the New England Journal of Medicine. Previous studies have shown that after weight loss, metabolism slows and hormonal changes cause an increase in appetite. In this small study people were asked to lose 10% of their body weight by going on a low-calorie diet. They were then placed on a maintenance diet. One year later their metabolism and hormonal levels had still not returned to normal, plus the subjects were starting to regain the weight despite the maintenance diets.
Their leptin levels fell by 2/3 immediately (when leptin falls, appetite increases and metabolism slows). One year later their leptin levels were still 1/3 lower than at the start of the study.
Other hormones (ghrelin was increased, peptide YY decreased) were also still changed as of 1 year later, increasing hunger.
Conclusion: it is very hard to lose weight and keep it off as your hormones work against you. Hormones enjoy their status quo. Not good news for dieters. The obvious conclusion of their study, in my mind, is to be ever vigilant after weight loss.
This was a small study. The weight loss was rapid and was caused by being on a very low calorie diet. Hopefully, more studies will follow, maybe studying how long it does take for hormone levels to return to normal.
My thoughts are to just exercise and eat healthy foods... a life-style change and not a diet. Hopefully natural weight loss will occur and the hormones will be tricked into normalcy. Maybe someone will do a study on metabolism, hunger hormones, and this lifestyle change at some point.
A new study shows that resveratrol may boost oral health. Resveratrol was found to supress growth of certain bacteria known to cause periodontal disease. Other studies in the past have shown resveratrol to increase length of life, to have anti-cancer and anti-inflammatory effects, cardiovascular benefits, anti-diabetes potential, energy endurance enhancement, and protection against Alzheimers Disease. Great news: all the more reason to enjoy red, purple, and black grapes. We keep some frozen and treat them as mini-popsicle-like snacks. (http://www.nutraingredients-usa.com/).
Looking together in the same direction.
