Summer's over, but that doesn't mean you can't start shedding pounds as early as today if it means you're going to get your best summer body next year.

The good news is that health gurus are right about what they say you should eat if you want to lose your unwanted weight. Yes, you should eat more fruits and vegetables, but be careful: not all fruits and vegetables can help you lose weight. In fact, others can help you gain more pounds.

That being said, high-fiber, low sugar fruits should be on your daily menu, and starchy vegetables like potatoes and peas should be out.

In a study published in PLOS Medicine, it was suggested that produce isn't created equal. The researchers noted that in the study, they investigated whether or not consumption of fruits and vegetables with higher fiber content or lower glycemic load is more effective in achieving a healthy weight than consumption of fruits and vegetables with a lower fiber content or higher glycemic load.

Researchers from the Harvard TH Chan School of Public Health and Brigham & Women's Hospital in Boston found that increase in fruit and vegetable intake led to a 0.53- and 0.25-pound weight loss, respectively. As cited by Today, a single serving of apples, berries and pears to one's weekly diet helps reduce one pound on an average.

While eating more fruit is great for weight loss, it has been noted that men and women should eat more berries, apples, pears and tofu/soy. For their veggies, on the menu should be cruciferous and green leafy vegetables such as cauliflower, broccoli, kale, radishes, Swiss chard, collard greens, rutabaga and turnips.

On the other hand, vegetables with high starch content, such as corn, peas and potatoes, lead to weight gain, as much as two pounds on average among the study participants.

It has also been noted that these fruits and vegetables are in season for fall. While you can get them year-round, The Guardian cited that the "farm-to-table" method of buying ensures that you get more of your food's nutrients, as opposed to the packed and pre-packaged ones you find in the supermarket.

That being said, the researchers cannot confirm the validity of the findings, saying that they are "generalizable" as "nearly all the participants were well-educated white adults." They also admitted that the self-reported measures during the study "introduced measurement errors."
