Fructose, a new paper proposes, is the pernicious little demon driving so many human metabolisms towards obesity. Although it's not the biggest source of caloric intake, it does trigger the urge to eat fattier foods, at higher quantities, resulting in overindulgence in food.
A major analysis, led by medical doctor Richard Johnson of the University of Colorado Anschutz Medical Campus, suggests that a decision to lose weight may not come down to a choice between ditching either carbs or fats, but a case of responsibly reducing both together.
Unfortunately, having significant quantities of the carbohydrate fructose in your diet won't make that so easy.
"Although practically all hypotheses recognize the importance of reducing ultraprocessed and 'junk' foods, it remains unclear whether the focus should be on reducing sugar intake, or high glycemic carbohydrates, or fats, or polyunsaturated fats or simply increasing protein intake," the researchers write in their paper.
"Here, we review the various dietary hypotheses for obesity. We propose that all of the various hypotheses are largely correct, and that although they outwardly seem incompatible, that they can all be unified based on another hypothesis known as the fructose survival hypothesis."
Fructose is a type of sugar that can naturally be found in fruit. Balanced by the vitamins and fiber therein, your daily apple, banana, and orange isn't so much an issue. The body can also make small amounts of fructose from carbohydrates such as glucose, and salty food.
