What Happens When We Don’t Eat Enough?

The body requires a particular amount of calories to function properly on a daily basis. Not eating enough to meet these requirements can lead to a variety of physical and mental ailments. The amount of calories needed by the body to function properly is known as the Basal Metabolic Rate (BMR).

BMR helps the body perform basic functions such as breathing, temperature regulation, organ functioning, digestion, blood circulation, and other vital internal processes.

Signs and Symptoms of Low Calories

There are various signs and symptoms, which indicate that the body is deficient in calories and they include:

• Dizziness
• Feeling Hungry
• Fatigue
• Listlessness
• Inability To Focus
• Shakiness Of The Hands

These signs typically show that you are short of glucose, which is the body’s basic source of energy to perform its daily activities. This condition is medically termed Hypoglycemia.

Signs and symptoms of insufficient calorie intake tend to disappear immediately you take in anything that contains glucose.

In order to keep your caloric level within normal range, you are expected to eat a balanced diet with enough calories to provide you with the energy you need to sustain the day. The amount of calories any one person needs depends on age, weight, weight goals, and levels of physical activity.

Below are some of health problems you may face if you continue eating less than your body requires for its daily functioning.

Unhealthy Weight Loss

Many people with the aim of losing weight restrict their daily intake of food. Although it is not wrong to do so, reducing it far beyond what your body requires for its normal daily functioning may cause health problems rather than help you lose weight. In fact, it may have the opposite effect in causing the body to go into fight or flight mode as a reaction to what it interprets as starvation. When the body perceives that it is being starved it will hoard every bit of food it possibly can to save for later.

In order to safely lose weight with reduced calorie intake, you shouldn’t lose more than two pounds a week. If you find yourself losing more, watch it as you just might be placing your health at risk.

Impact On The Digestive System

Just as previously stated, a person who doesn’t eat enough will have a very slow metabolism as a result of the body trying to conserve energy.

The digestive tract, which is responsible for breaking down, drinks and foods into its simplest form so that the ensuing nutrients can be used by the body might become so severely damaged that it no longer digests food properly.

At this point, production of digestive enzymes by the pancreas occurs more slowly than it is supposed to leading to an ailment called diarrhea. If you have ever experienced diarrhea before then you know that it’s an ailment of much inconvenience and discomfort and it may cause dehydration and depletion of essential nutrients and vitamins from the body.

Heart Related Problems

By restricting your required caloric intake for a long period of time, malnutrition might set in. You tend to have slower metabolisms because your body senses the scarcity of food and switches to starvation mode where it slows down the functions of the body in order to conserve energy.

According to health experts, people who are malnourished are likely to experience situations where their heart beats irregularly. If this happens continuously, the heart muscles may become weak followed by a corresponding decrease in the size of the heart chambers, potentially leading to heart attacks.

Deficiencies In Certain Nutrients

By restricting the amount of calories you consume on daily basis, you are likely to be deficient in some nutrients including folate, vitamin B-12, and iron. Deficiencies in these nutrients could lead to anemia, which is a disease that affects the red blood cells. Red blood cells are responsible for transporting oxygen to various organs and tissues in the body. Anemia, which occurs as a result of nutrient deficiencies, can lead to shortness of breath, fatigue, pale skin, dizziness, irregular heartbeat, cold hands and feet, headache, and cognitive problems.


Not eating enough, just as overeating has its own set of severe health implications. You should never engage in any of these acts no matter the situation you find yourself. The best way to remain healthy is to eat a healthy well-balanced diet that provides you with all the nutrients you need to survive and thrive.\\\"\\\"
