Can overeating fruits and vegetables make you fat?
Where Does The "Fruit Makes You Fat" Idea Come From?
Many people who believe fruit makes you fat adhere to the principles of "broscience," which Urban Dictionary accurately defines as "the predominant brand of reasoning in bodybuilding circles where the anecdotal reports of jacked dudes are considered more credible than scientific research." In this case, while hearing what others have to say is generally a good thing, it's important to understand that genetically gifted or "assisted" individuals often look the way they do in spite of their approach, not because of it. Others believe the fructose (a type of sugar found in fruit) causes fat gain. Some studies suggest that fructose ingestion leads to insulin resistance, elevated blood cholesterol levels and increased fat gain, especially in the abdominal area.
Additionally, fructose lowers the amount of insulin released in response to meals. This in turn lowers the circulating levels of the hormone leptin, which is responsible for increasing feelings of fullness and raises the hunger-promoting hormone ghrelin. This scenario can lead to excess calorie consumption, which can cause fat gain.
Several studies show an association between beverages containing fructose (or high fructose corn syrup, which is not found in nature) and weight gain. However, there is good research that suggests it is the calories from the sugar and not the particular type of sugar that is responsible for the weight gain.
Additionally, fruit contains relatively low levels of fructose compared to sweetened beverages. For example, a medium apple contains around 13 grams of fructose and 90 calories. A 20-ounce Coke has 65 grams of sugar, about half of which is fructose, and 240 calories. (And, yes, the calories should be 260 , due to 4 calories per gram of sugar. I couldn't find an explanation for this discrepancy.)
If Fruit Doesn't Make You Fat, What Does?
Excess calories cause weight gain. If you eat more calories than you burn, you will gain weight no matter where the calories come from. So does fruit make you fat? It can in the sense that if you eat too much of it (or too much of anything) you will gain weight. If you eat higher calorie fruits like bananas you will be more likely to put on weight than if you eat lower calorie fruits like strawberries.
Fruit is packed with nutrients, has a high water content that makes it filling, and contains fiber. In moderation, fruit is an excellent choice as a healthy source of carbohydrates.
