Expatriates planning to lose weight to avoid making a claim on international health insurance policies have been advised to avoid dieting.
Roz Watkins, non-diet weight loss expert and owner of The Enlighten Programme, claimed engaging on a course such as this "makes you fat".
Furthermore, recent research by bread company Hovis found these programmes generally only last for 15 days, with 35 per cent of women ending up heavier than when they started the regime.
Instead, Ms Watkins suggested people focus on whether they are hungry and if their meals make them feel full.
She recommended "natural foods" and limiting the amount of processed meals and sugar consumed.
Eating slowly was also pointed out as a good way to lose weight, with the expert noting this helps individuals notice when they are feeling full.
"If you are regularly eating when not hungry, you need to work out what is going on," Ms Watkins advised.
"Just trying to eat less won't solve this," she commented.
