Are you Suffering from the Yo-Yo Syndrome?
A weight loss program which involves losing and gaining weight in a cyclic manner is known as yo yo dieting or weight cycling. Though scientists know for sure that proper diet increases the chances of longevity by 50 percent, very little is known about weight cycling. Now, researchers at the University of Pennsylvania have discovered that weight cycling can cause undesirable and permanent DNA changes in the body, making further weight loss efforts futile.
The results of their findings are published in the December 1st, 2010 issue of The Journal of Neuroscience. The study was funded by National Institute of Diabetes, the University of Pennsylvania Diabetes Center, Digestive and Kidney Disease, AstraZeneca and the Health Research Formula Fund.
Does Yo Yo Dieting Cause Epigenetics?
- Experimental mice lost 10 to 15 percent of their body weight after three weeks of limiting dieting similar to weight loss observed in humans.
- Mice placed on quick-fix diets were found to have higher levels of corticosterone, a stress hormone and also showed depression symptoms.
- Genes associated with regulation of stress and eating habits were found to be changed in these mice.
- Earlier research studies have revealed that the DNA in the genes can change owing to the experiences we have, an effect technically called epigenetics.
- What was more worrying to discover is that even when the mice were brought back to their normal weight, the changes in DNA remained.
- The researchers subjected these mice to stressful conditions and found them consuming more fatty food than normal mice.
With one in every three Americans being obese, yo yo dieting is a well-known weight loss technique in this country. But, the present study reveals how such a dieting reprograms the brain and makes any effort to diet successfully turn futile. The study also opens doors for weight loss drugs in the future which can work by targeting the stress-related molecules produced by this diet. The study confirmed that gaining weight was much easier than losing weight when it came to the Yo-Yo’s (as they are called) . Kelly Brownell, a psychologist explained this study as diet-induced obesity, which can be very much applicable to people who are trying to cut calories but only as a temporary phase and then gaining the weight back again.
How do you Get Rid of the Yo-Yo Syndrome?
Listed below are few tips from experts to get rid of the Yo-Yo Syndrome:
- Plan portion control of your meals – eat small meals and increase the frequency of the meals.
- Exercise to keep your body moving.
- Include variety in your diet – proteins, carbohydrates, fat, grains, fruits and vegetables for minerals and vitamins etc.
- Consult a professional, doctor or dietitian to solve your weight problems.
- Focus on slow and steady weight loss.
- Allow healthy snacks in between your meals.
- Do not rely too much on supplements.
- Drink plenty of water, fruit and/or vegetable juice.
Dieting does not mean giving up food. Instead, it has a lot to do with recognizing the foods that can fool you and the healthy intake of foods and nutrients coupled with exercise and activity. Look for effective weight loss plans, like the above, to guarantee a permanent ideal weight.
Benefits of Loosing Even Slightest of Weight
The immune system is the technical name given to the natural protection system of our body. It consists of a collection of different types of cells which work as a unit saving our body from germs, viruses and other invaders. There is a natural balance maintained by these cells among themselves. Excess fat in obese people is one among the many factors which disturb this balance. As a result, these protector cells turn hostile instead.
Researchers from Sydney’s Garvan Institute of Medical Research, have found recently that even slightest weight loss can have a very positive influence on the immune system of obese people suffering from Type 2 Diabetes. When the immune system cells turn hostile, Pro-inflammatory’ immune cells are produced in large number to cause destruction in the body. The research study found that by reducing body weight in obese diabetic patients, the presence of these Pro-inflammatory’ immune cells can be reduced by 80 percent. The results of their findings are published in the April 2010 issue of the on line Journal of Clinical Endocrinology Metabolism.
