According to a research presented at the Obesity Society meeting shows that people who ate an apple before lunch consumed almost 190 calories lesser than when they had an apple before lunch.
"This suggests that eating something like a piece of fruit that's low in calories before your meal might be a great strategy for reducing calorie intake," says Julie Flood, a researcher at Penn State. "It looks like solid fruit is more filling than fruit juice, and people perceive them differently. They look at an apple and think it's going to fill them up."
Many fruits and vegetables that are low in calories and have high amount of fiber when consumed help us to eat less and lose weight. So have an apple a day and keep the weight away.
