A gene involved in regulating blood pressure has been identified as a factor in whether women are prone to yo-yo dieting.
A study at Maastricht University, conducted by Prof Edwin Mariman’s research group and published in the scientific journal PLoS ONE by Dr Ping Wang, was conducted to find out why 80 per cent of people who lose weight gain it all back within a year.
The scientists tested blood from a group of women in an attempt to identify proteins that predict whether a particular person will be prone to yo-yo dieting.
Of the 34 factors examined in the blood, an enzyme known as ‘ACE’, normally associated with regulating blood pressure, showed up in high concentrations in the blood of women in the study who put weight back on after weight loss.
Scientists are now hoping to create a test that will determine the risk of yo-yo dieting in anyone, based on a blood sample and a patent has been applied for.
Many people in the UK combat yo-yo dieting by working closely with a dietician or personal trainer to maintain a steady, healthy diet, combined with an exercise plan that ensures any weight loss is manageable and healthy.
Certain parts of the UK have benefited from the development of wellness clinic, whether dieticians and nurses offer one-to-one advice on how to control your weight. For people in the south east of England seeking a personal trainer Colchester is a good place to start. The SureSlim Wellness Clinic in the city was opened in 2008 and provides individually tailored diets and training programmes for people of all ages and weight ranges.
Yo-yo dieting is linked with a number of health risks, as the rapid loss of weight affects a person’s physical, emotional and mental health. Mood swings and extreme food cravings can lead to depression, as well as eating disorders like anorexia and bulimia.
Low calorie diets also lead to people missing out on essential nutrition due to the poor variety of foods they eat whilst dieting. This can lead to nutritional deficiencies that have a long-lasting, damaging effect on health.
Iron deficiency anaemia, vitamin B12 deficiency and potassium and sodium deficiency are amongst the risks of crash or yo-yo diets. Organ damage can also result from the vital organs being deprived of energy required to function correctly, with liver failure, kidney failure, heart attacks and strokes all possible consequences of a crash diet. There are a lot of reasons for you to opt for long term weight loss, whenever you plan to return to normal weight.
