Expatriate health insurance customers who have weight problems should do their best to avoid advice from so-called gurus, an independent nutritionist has said.
Jessica Villa, a nutritional consultant for Big Matters, pointed out there is a wide range of conflicting ideas about the causes of obesity, but the solution is straightforward.
"Mathematically, nutrition is simple; a normal healthy woman should eat 1900Kcal a day and a man 2100Kcal a day. If you ingest that and you burn it, it would be impossible to gain weight – if not the storage will creep up on your belly, and you know the results," she explained.
Ms Villa expressed her belief that a small proportion of research into nutrition is valid – "the rest is just money-making".
Her comments follow a study from the University of California, Davies and the National Center for Food Safety and Technology in Illinois, which suggested how individuals can eat potatoes – which have a high glycemic index – and still lose weight.
