Fruit and vegetables don't help with diet: study

Upping the amount of fruit and vegetables in your diet won't help you lose weight, according to a new study that goes against the advice of many nutritionists.

Researchers at Purdue University in Indiana found trying to fill up on fruit and vegetables actually made people more hungry, with fruit juice before a meal being particularly bad and leading participants to consume an additional 420 kilojoules.

But researchers found that eating fresh fruit and dried fruit before a meal could help people feel fuller and consume less calories.

The researchers studied 34 participants, some of whom were overweight or obese, who ate between 3284 and 3435 kilojoules when they were offered a lunch of all-you-can-eat macaroni and cheese.

When the participants were given fresh and dried fruit before their meal, they ate a total of 2837 kilojoules, including the fruit.

But when they were given fruit juice beforehand, the participants consumed a total of 3728 kilojoules.

Researchers then extended the fruit juice diet for some participants for eight weeks and found they gained up to 2.5 kilograms.

Lead researcher Dr Richard Mattes said the study showed adding fruit and vegetables to your diet could make it harder to lose weight because they can leave you feeling empty.

He added that people were mistaking feeling thirsty for being hungry, which was why drinking fruit juice made participants eat more.
