Why Do We Get Tired While Eating Too Sweet?

The body reacts to the consumption of sweets in various ways, and tiredness is one of them. This is because sugar metabolism is slower compared to other foods - like fish, poultry, nuts and vegetables. Its metabolism is slowed down by the structure of its molecules, making the digestive process and energy storage require maneuvers, so to speak, more elaborate.

In Ayurvedic medicine, for example, it is recommended to eat sweets before salting, for this reason. And research in the West also shows that the content of what we eat is what determines the health of the body, with calorie accounting being less relevant.

What happens in the body after eating too sweet is explained by Jonah Lehrer. When we consume sugar, the chemical in the brain that keeps us awake - orexin - is inhibited. Therefore, the sensation of tiredness appears when we eat a lot of sweets. Orexin, discovered in 1990, is a neurotransmitter located in the hypothalamus, from which the circadian rhythm originates, and the feelings of hun

ger and satiety.

When we consume proteins, the reaction in the body is different from that of sugar. Proteins, instead of inhibiting, stimulate the orexin cells, making them active, and then we feel liveliness and energy, the sensation of being awake. And this happens even when little protein is consumed, even when consumed along with sugar. Here's a good tip to avoid fatigue - eat a dessert that contains protein.

Why eat too much candy?

As we have seen, it is erroneous that the consumption of sugars( or carbohydrates, which quickly turn into sugar) will increase your energy in the long run. That happens, but for a little while. Metabolism increases with the intake of sugar to the point of burning of calories. Then comes the feeling of tiredness and sleep.

Even so, almost all the processed products we consume contain large amounts of sugar, unless you are buying sugar-free products, and this should be expressed on the packaging. Doctors and researchers warn of this type of food, but perhaps many people ignore it because they are unaware of its health effects.

Consumption of soft drinks, for example, ages the body from the cells at the same speed as cigarettes, according to a study conducted at the University of California. It is said that almost the entire body feels the effects of eating too much sugar, whether in the short or long term, in a more complex way than just gaining weight or tiredness.

Signs of the Body

Obesity is a relevant sign of excess sugar, as well as insulin imbalance, sugar sensitivity, or hypoglycemia. In addition, these signs may mean diabetes at a treatable stage or that progress to Type 2 diabetes.

Other symptoms may occur when a person has a habit of eating very sweet in parallel to these:

1. Obesity

Dr. Kristen F"Gradney, Director of Metabolism and Nutrition Services at the Reginald Our Lady of the Lake Medical Center, says that obesity is a dangerous cycle."Too much sugar equates to excess calories, which amounts to being overweight in the form of fat. Foods with lots of sugar accumulate calories and do not contain fiber or protein. And if you only eat sugar, you can get fat, and still feel hungry. For example, one can gain 500 calories a day with the consumption of a chocolate bar and a soda. "

2. Insulin Imbalance

When you eat very sweet, blood sugar levels will rise, and by the principle of homeostasis, the pancreas will release insulin, and with it, blood sugar levels will decrease sharply. At that moment, you feel tired. That's the role of insulin, remove excess blood sugar and stabilize it. Then the body may feel the need for more sweet again to regain the energy feeling previously felt by the high blood sugar levels.

3. Sugar Sensitivity

Other neurotransmitters present in the brain, serotonin, which acts on appetite, sleep and memory functions, and beta-endorphin, are also influenced by the large amount of sugar in the body. Tiredness and lack of concentration are indicators of low serotonin levels. Depression and craving for more sweets are signs that beta-endorphin levels have decreased.

Sugar sensitivity is related to the rate at which blood sugar levels decrease, other than diabetes, which manifests as they increase.

4. Constant colds

The immune system can be weakened when you have a habit of eating very sweet, which makes it difficult to fight viruses and bacteria.

5. Depression or anxiety

After the strong desire for sugar to finish, the body becomes physically and emotionally tired when it manifests depression, lethargy, sadness, isolation, anxiety and worry.

6. Skin and foot problems

Acnes, rosacea, eczema, oiliness or dry skin may occur due to the inflammatory effect of sugar on the skin. There are also effects on the feet, such as plantar fasciitis, and dark circles, which can arise due to adrenal exhaustion.

7. Hypoglycemia

The release of insulin can happen naturally if you eat very sweet, causing symptoms like fatigue, weakness, headache, tremors, dizziness, nervousness, sweating and mental confusion caused by the fall of glucose.

According to National Diabetes Information Clearinghouse, hypoglycaemia can occur when you are fasting, with unknown causes, or a few hours after meals.

Whether in diabetics or non-diabetics, hypoglycemia, or low blood sugar levels, is not a disease, but the symptom of some problem. It may manifest itself after ingestion of sweets and carbohydrates such as cakes, breads and pasta.

Consumption of carbohydrates that contain gluten can cause fatigue in people with celiac disease, as they stimulate an inflammatory response in the small intestine, due to the high degree of refining of these products. The clinical signs are diverse: tiredness, sweating, insomnia, dizziness, nervousness, panic attacks, or headaches.

8. Pre-diabetes

Unlike diabetes, pre-diabetes characterizes a stage where sugar levels are not as high but above normal. The cause is in insufficient insulin, or inability of the body to process it.

Weight loss and elimination of sweets and carbohydrates can cure pre-diabetes. But it can turn into type 2 diabetes, if neglected or undiagnosed in time.

9. Diabetes

Drowsiness after eating too sweet may be a consequence of diabetes, especially if you are taking insulin, or by excessive consumption of alcohol, tumors and endocrine deficiencies.

10. High blood pressure

In 2010, at the University of Colorado in Denver, a survey was made relating high blood pressure to high sugar intake. It has been shown that, unlike what is thought, sugar would be responsible for the increase in pressure.

11. Heart Problems

A study conducted in mice by the Case Reserve Western University demonstrated that a high sugar diet accelerates death and heart problems rather than carbohydrates and fats. The study can not be applied to humans.

12. Metabolic Syndrome

Drowsiness may be a symptom of metabolic syndrome, a condition in which the body does not respond properly to insulin secretion. What happens is an instability in blood sugar levels, which is what causes the feeling of tiredness.

Other symptoms

Each person reacts differently, and symptoms vary in their manifestations and frequency.

  1. Difficulty concentrating due to mental confusion, nervousness or irritability, even difficulty performing customary tasks.
  2. In the case of people with fragile digestive system, stomach problems may occur, in addition to fatigue, and the development of irritable bowel syndrome.
  3. Tiredness can also come accompanied by dizziness, which is the most common symptom that presents itself after eating too sweet.


The Mayo Clinic recommends that sugar intake should be controlled. Check the concentration of sugar mainly from processed foods and beverages, such as soft drinks for example. And the moment you choose to withdraw the sugar from the diet, do so gradually.
