In a society where people are perturbed about their health, we tend to watch what we devour. But no matter how vigilant we are, some ingredients can sneak past our radar especially sugar. Sugar is a soluble carbohydrate that supplies the body with needed energy. It contains glucose and fructose. The body naturally produces glucose. It’s the fructose part present in sugar we consume that can be precarious to our health.
In this review, we are going to explore the way sugar makes you fat.
1. Leptin resistance:
When one ingests foods that are high in fructose sugar, they ultimately lose the aptness to control their appetite. Fructose encourages weight gain via the technique of triggering more consumption of food and impede the burning of fat in the body. Increased consumption of fructose makes the liver metabolize it into more fat, unlike glucose. Fructose tricks the brain into thinking the body is starving prompting you to consume more food, in the long run, making you fat. This clearly shows how leptin resistance makes you gain weight
2. Insulin resistance:
The food industry has changed drastically over the past few decades. We have witnessed more and more processed foods being manufactured that contain high levels of fructose as a sweetener. With the increased consumption of soft drinks, baked products, desserts, and condiments, all loaded with high fructose corn syrup cause reduced insulin sensitivity that is associated with impaired hepatic insulin action. Frequent ingestion of foods with high fructose instigates hypertriacylglycerolemia, a process where fructose in the diet stimulates insulin resistance and we all know how insulin is vital in regulating sugar in the blood
. The moment this is hindered weight gain can be a problem.
Satiety is the state of feeling fullness after consuming food which is controlled by the hypothalamus in the brain. Massive consumption of fructose in the diet can always hamper these signals being sent to the brain which in the long run alters satiety and food intake. When we consume glucose it lowers the blood flow to the brain limiting the signals the hypothalamus is receiving and leaves us with the feeling of fullness whereas fructose does not. This indicates that a diet of fructose e.g sweetened soft drinks will always leave you feeling hungry even after consuming a lot of it making you feel like you need to eat more food than is necessary. Hence we see that fructose does not lower ghrelin, a hunger hormone. This encourages more food intake from the lack of feeling full even after eating, which makes you fat in the end.
We know that sugar is sweet and can make you overindulge in foods. The consumption of foods high in fructose makes the body release immense levels of dopamine. A chemical messenger that relays signals between brain cells and is always linked to addiction. Consuming foods rich in high levels of fructose promotes the release of this chemical but over time this reduces and the receptors begin to receive less stimulation. This means that to get that feeling one was used to, more intake of food is required to trigger the rewarding feeling which in the end leaves you eating more food and making you put on more weight from the excessive feeding.
Sugar is very vital in our diet especially glucose. Fructose, on the other hand, can be precarious to our overall health. Always watch what you consume and try as much as possible to avoid too much fructose in your diet.
