The Endocrine Society reported at their AGM of 12 June that if you are planning on a low calorie diet to get in shape for those summer clothes then you need to have good levels of vitamin D in your body at the start if you want it to succeed.

The study was reported on from a study at the University of Minnesota and although we associate Vitamin D deficiency with obesity, it’s never been clear as to whether low levels of vitamin D causes obesity or the other way around. The study put their test subjects on a diet that provided 750 calories a day less than they actually felt they needed. Most of their people had low levels of vitamin D at the start, but surprisingly even low levels were able to predict how successful the diet would be. The more vitamin D in their blood, then the greater the weight loss – and vice versa.

Probably of more interest before you shimmy into that swimsuit is the fact that higher baseline levels of vitamin D levels also predicted there would be a greater loss of fat from the abdomen – the prime target for most dieters.

Just taking vitamin D as a supplement won’t help you lose weight on its own. Sadly the same advice applies as usual – eat less, exercise more and focus on healthy foods rather than saturated fats and alcohol. Liqueur chocolates are probably the worst combination, so wait until Christmas!
