London: Keeping healthy foods at eye level in the fridge could help you shed the flab and stay trim because you eat what you see first, say psychologists.

Simple changes like moving chocolate and crisps out of sight and putting more wholesome foods where they can easily be seen can help dieters to eat better without even realising it, according to them.

Serving food on smaller plates and eating in the kitchen or dining room rather than in front of the television can also help you subconsciously reduce the amount you eat without testing your willpower, a newspaper reported.

Dr Brian Wansink, a leading psychologists, said that when one's mind is on other things one simply eats what is in front of one whether he or she is hungry or not.

One experiment at Cornell University found that people pour 37 per cent more liquid into short, wide tumblers than tall, thin glasses. Another test in which 60 people were served soup in 650 ml bowls, half of which secretly refilled themselves as diners were eating, showed that those with the "bottomless bowls" ate 73 per cent more without realising it.

Dr Wansink said, "Most of us have too much chaos going on in our lives to consciously focus on every bite we eat, and then ask ourselves if we're full. The secret is to change your environment so it works for you rather than against you.”
