A healthy diet that can be maintained in the long term is key to achieving weight loss, one expert has advised.
Alison Wetton, founder and chief executive officer of All About Weight, warned those trying to shed pounds that reverting to "bad habits" can cause weight to go back on.
Expat health insurance customers developing a diet that will help them become slimmer may want to follow the advice of Ms Wetton and ensure they consume food that still contains "adequate protein, essential fats, vitamins and minerals".
"To lose weight safely you must make sure that your diet provides less energy than you need to maintain your current weight," she remarked.
Research released by The Co-operative Pharmacy yesterday (November 21st) revealed some people would take drastic and dangerous measures in order to lose weight, with one in ten stating they would starve themselves.
Among those aged 18 to 21, the number rises to almost one in five.
Furthermore, one in 20 of all respondents would consider undergoing surgical procedures such as having a gastric band fitted, the survey showed.
Ms Wetton called on people to have a long-term strategy in place when planning weight loss, advising that while it is "fine" to begin the process by using a "nutritionally adequate diet", it is important to develop a diet and lifestyle "that you can realistically continue permanently".
Being overweight has numerous health risks and research conducted last month by the University of North Carolina in the US revealed it can make people more susceptible to flu.
The study, published in the International Journal of Obesity, found those of a healthy weight responded better to inoculations than overweight individuals.
