The sweet truth, according to science

One of the most common nutrition myths is the belief that eating fruit leads to weight gain because of its natural sugar content. The truth is research continues to show that consuming more whole fruits is associated with weight loss and better overall health.

What the Research Shows

A 2016 review published in Nutrients examined decades of data and found that increased whole fruit consumption is linked to a reduced risk of obesity. In fact, they found that eating more whole fruit usually helped prevent weight gain and may even lead to modest weight loss!  

Why Fruits Can Help You Lose Weight

•    Low in Calories, High in Volume:  Most fruits are low in calories but high in water and fiber, which means they take up more space in your stomach without adding a lot of calories. This concept, known as volumetrics, helps you feel full and satisfied while consuming fewer calories overall.  
•    They Keep You Feeling Full:  Fiber in fruits slows digestion, helping you feel full longer and curb overeating.
•    They Offer Important Micronutrients:  Fruits are loaded with vitamins and minerals like vitamin C, A, and potassium that support metabolism.  
•    They Contain Plant Compounds That Fight Fat:  Some fruits have special natural chemicals (called phytochemicals) that may help burn fat or stop new fat cells from forming. Berries, apples, and pomegranates are especially good at this.
•    They Help Your Gut Work Better:  Fiber and antioxidants in fruit support healthy gut bacteria, which are linked to a lower risk of obesity.

When Fruit Might Contribute to Weight Gain

Fruit Juices and Dried Fruits Are Tricky:  While whole fruits are helpful, fruit juice, canned fruit in syrup, and dried fruits are easy to overconsume and usually stripped of fiber and often have sugars added. They deliver the sugar hit without the fullness, leading to excess calorie intake.
High Sugar Content Can Add Up:  Some fruits, especially in large amounts, do have a lot of natural sugars, which can contribute to fat storage if not balanced within a healthy diet.

Form Matters More Than Fruit Itself:  Whole fruits = good. Processed fruits or juice should be consumed in moderation, especially for children.
