Expatriates with international health insurance may wish to consider developing a realistic plan when trying to lose weight.
Registered nutritionist Dr Carina Norris said healthy eating regimes should be ones that can be sustained.
They should "fit in with your lifestyle and your eating personality", she declared.
The expert pointed out some weight-reduction plans can provide people with inadequate nutrition, while "gimmicky crash diets" are very hard to stick to.
Although she admitted men and women can initially lose a few pounds with these, she said they will quickly put it all back on again.
Therefore, individuals who like to eat between meals should develop a diet that "includes lots of healthy snacks", as this will help them stay with it, Dr Norris claimed.
Every calorie ought to count, with no items like fizzy drinks or sweets consumed, the expert argued.
She argued people should eat energy in "really nutritious things that are going to sustain you and keep you healthy".
Some of her suggestions include wholegrain carbohydrates, low-fat proteins, fruits and vegetables.
"Drink lots of water," the doctor declared.
Recent research from the European Health Interview Survey found only eight per cent of females and 7.6 per cent of males in Romania were obese in 2008 to 2009, which made this the least-overweight country of the 19 member states surveyed.
Similarly low levels were seen in Italy, in which 9.3 per cent of women and 11.3 per cent of men had a BMI over 30 during this timeframe.
The highest levels were recorded in the UK – in which 23.9 per cent of women and 22.1 per cent of men were obese – and in Malta, where these figures reached 21.1 per cent among females and 24.7 per cent within the male demographic.
Experts consider obesity and being overweight to be a serious issue in public health.
