For years there has been an ongoing search for the main cause of obesityIt is a non-contagious disorder that affects the whole world like a real epidemic. Most experts point to a disease Multifactorial causeAlthough their sum would not be enough to explain this. In other words, a search is underway for the prime suspect.
A new article published in the magazine obesity Led by Richard Johnson of the University of Colorado Anschutz Medical Campus, the team formulates its accusation against a particular molecule: Fructose. Although this sugar is found naturally in fruits, from which it gets its name, it appears in a less healthy form such as: Food additives are everywhere.
According to Johnson and colleagues, fructose would be the culprit Human metabolism becomes dysfunctional It ultimately leads us towards obesity. Although it is not the largest source of calories, this molecule would trigger the need to eat fatty foods in larger quantities, leading to increased calories consumed throughout the day.

According to this new work, the decision to lose weight will not simply be a choice between eliminating carbohydrates or fat, however Reduce both responsibly together. However, if carbohydrates are consumed with large amounts of fructose in the diet, it will not be so easy.
“Although almost all hypotheses acknowledge… The importance of limiting ultra-processed foodsThe researchers explained that it is still unclear whether we should focus on reducing our intake of sugar, high-glycemic carbohydrates, fats and polyunsaturated fats specifically, or simply increasing our intake of protein.
After reviewing various nutritional hypotheses, they suggest that They are all largely true.. Although they seem seemingly incompatible, it is possible to unify them all based on another hypothesis known as “Fructose survival hypothesisIts effect on the development of degenerative diseases in EL ESPAÑOL has already been addressed in a previous study conducted by Johnson himself.
Eat apples, bananas, or oranges daily. Dense in fiber and micronutrients, it’s no problem. In fact, the body itself can produce small amounts of fructose from carbohydrates such as glucose and salty foods.
The real problem comes when large amounts of fructose are consumed Refined table sugar, corn syrup and other sweeteners. Concentrations of fructose can build up quickly in our diet, often without us even realizing it.
According to Johnson’s team, Fructose metabolism in the body It causes the fall of a compound called Adenosine triphosphate (ATP)Which provides energy for cellular processes in the body. When ATP drops to a low enough level, it is a signal to the body that it needs more fuel. “And this is what we know.”hungerAnd it makes us eat more.
“Basically, the theories that place a series of metabolic and nutritional factors at the center of the obesity epidemic are all pieces of the puzzle unified by one final piece: Fructose. Fructose is what keeps our metabolism in-between In low consumption mode and loss of appetite controlThey explained that fatty foods are the main source of calories that will lead to weight gain.
In fact, this low consumption mode is activated Even if there are fuel reserves on hand. Although plenty of energy is available in the form of stored fat, fructose prevents the body from using it. In some contexts, this is a positive thing: Bears are preparing to Hibernation They maintain their fat reserves by eating fruit. However, human consumption of sugary foods and drinks leads to excessive consumption, which is harmful to health.
