11 Things You Should Know About Low-Calorie Diet

1. Helps fight cancer

A recent study has shown that people who followed a diet of only 900 calories a day had a lower risk of developing cancer. Research has shown that a low-calorie diet slows the progress of cancer. People who are obese may have an increased risk of cancer. Maintaining a healthy weight through calorie restriction may inhibit the progression of cancer. A diet rich in fruits and vegetables, low in fats and calories, and nutrition can prevent cancer.

Fruits and vegetables are low in calories and high in fiber, vitamins, minerals, and various cancer-fighting phytochemicals. Also, low-fat dairy products can be a healthy part of your diet. Some foods, like red meat, and grilled or barbecued meat, may contribute to the development or spread of cancer.

2. Helps weight-loss

A low-calorie diet can help you lose weight. Eating fewer calories results in weight loss, but consuming too few calories over a long period can be harmful to your health. Just don’t cut too many calories. Eating less than 800 calories a day puts your body into starvation mode. Cutting too many calories can result in weight gain, muscle loss, and malnutrition.

Eating too few calories can cause decreased bone density, irregular heartbeat, brittle nails, dry skin, low blood pressure and blood sugar levels, dizziness, fainting, hair loss, fatigue, cessation of menstrual periods, and constipation. A diet of fewer than 800 calories is not recommended. Also, avoid starvation because it slows down metabolism and causes hunger.

3. Lowers your blood pressure

Low-calorie diets can help you lose weight and lower blood pressure. To control high blood pressure, eat foods lower in calories, fat, and salt. By counting calories and monitoring your weight, you may be able to lower your blood pressure. Sugary foods are high in calories. High sugar intake is also linked to high blood pressure. Blood pressure is the pressure of blood in your arteries. High blood pressure (also called hypertension) means that your blood pressure is consistently higher than the recommended level.

High blood pressure is not usually something that you can feel or notice. This is why it’s sometimes called ‘the silent killer’. Symptoms of extremely high blood pressure are severe headaches, fatigue, difficulty breathing, irregular heartbeat, vision problems, chest pain, blood in the urine, and pounding in the chest, neck, or ears.

4. Prevents diabetes

Another study has found that people, who consumed only 900 calories a day for two months had lesser chances of developing type 2 diabetes and losing weight. A low-calorie diet can remove fat that clogs the pancreas and helps with weight loss. Type 2 diabetes occurs when the pancreas is unable to produce sufficient insulin. Type 1 diabetes is a relatively uncommon type, affecting only about 1 in 250 Americans. Type 2 diabetes affects 90 to 95 percent of diabetics. Type 1 diabetes, also known as diabetes mellitus, is characterized by elevated levels of glucose in your blood.

The symptoms of diabetes are excessive thirst, extreme hunger, nausea, possible vomiting, increased fatigue, unusual gain of weight or loss, irritability, blurred vision, slow healing of wounds, frequent infections, and numbness or tingling in hands.

5. Reduces neurological damage

Another study has found that a low-calorie diet reduces weight and neurological damage after a stroke. A new study has found that a low-calorie diet can reduce the risk of developing Alzheimer’s disease. A reduced caloric intake has been linked to a lower risk of mental decline. Alzheimer’s disease is a brain disease that slowly erodes memory and thinking skills. The risk of developing Alzheimer’s disease may be increased by a family history of the condition, increasing age, and previous severe head injuries.

Alzheimer’s disease is the most common cause of dementia. The symptoms of Alzheimer’s disease are: becoming confused about time or place, memory loss that affects daily life, problems with words, poor judgment, withdrawal from activities, and changes in mood and personality.

6. Cardiovascular disease

–A calorie diet is highly effective in reducing the risk of cardiovascular disease in humans. Cardiovascular disease is caused by unbalanced diets and physical inactivity. Cardiovascular disease is a major cause of death in the United States. Fruits and vegetables are naturally low-calorie nutrient-dense foods. A diet rich in vegetables and fruits, and low in calories, can help reduce the risk of heart disease and stroke. There are more than 60 forms of cardiovascular disease.

The most common symptoms are pain in one or both arms, the left shoulder, neck, jaw, or back, chest pain or chest discomfort, shortness of breath, dizziness, nausea (feeling sick to your stomach), faster heartbeats, abnormal heartbeat, feeling very tired and reduced tolerance to physical activity.

7. Constipation

Low-calorie diets can cause constipation. Constipation can be caused due to insufficient intake of food or water, including low calories. Most people with constipation can be treated with changes in diet. Not drinking enough water not eating enough fiber or consuming a low-calorie diet can cause constipation. Not eating enough fiber, such as fruit, vegetables, and low-calorie foods also can cause constipation. Constipation symptoms and signs are fewer bowel movements than normal, pain and straining when passing stools, stomach pain, stools are hard and dry and may be large or small in size like pellets, sore bottom, unpleasant smell due to passing wind, and leaking of liquid or loose stools.

If you’re suffering from constipation, try to eat more low-calorie fruits and vegetables. Also, drinking plenty of water can help prevent constipation.

8. Fatigue

Eating very low-calorie diets can cause side effects, like fatigue. Low blood sugar can also be caused by not eating enough throughout the day. The symptoms are impaired concentration or short-term memory, severe enough to affect routine activities at home, work, school or social functions, sore throat, muscle pain, pain in several joints, enlarged lymph nodes (swollen glands) in the neck or underarm area, with no redness or swelling, headache, multi-joint pain without swelling or erythema, muscle pain, post-exertional malaise for longer than 24 hours, sore throat, significant impairment in short-term memory or concentration and tender lymph nodes.

Additional causes of fatigue may include anemia, low vitamin b12 or vitamin D levels, and an underactive thyroid. Increasing your calorie intake can help reduce symptoms of fatigue.

9. Muscle loss

Low-calorie diets can cause muscle loss. Cut calories as much as you can. Instead of worrying about your body weight, you simply eat as little as possible. Large deficits are not appropriate in all situations. To keep your body healthy and build muscles, you need to maintain a low-calorie diet. Cutting calories forces your body to take energy from other sources. The natural process of aging can cause muscle loss.

Here are some reasons why you’re losing muscles: you don’t eat enough, you work to exhaustion, you favor low-calorie full-body training, you shun stretching, you only eat sporadically, you rarely alter, you only train what you see in the mirror and you don’t get enough sleep. You can build muscles even while sleeping.

10. Very low-calorie diets

Did you know that very low-calorie diets can harm your health? Very low-calorie diets typically get a bad rap. It is not an easy diet to follow. They are hard to follow for an extended period. Very low-calorie diets are defined as 800 calories (or less) per day. Very low-calorie diets are not recommended for pregnant or breastfeeding women. They lower metabolism and have been known to decrease muscle mass.

Very low-calorie diets may not be nutritionally complete. Not getting enough calories can leave you hungry. People on a very low-calorie report minor side effects such as fatigue and nausea. Other side effects can include dry mouth, constipation or diarrhea, headache, dizziness, cramps, and hair thinning.

11. Menstrual issues

Periods can stop for all sorts of reasons. Rapid loss of weight and low-calorie intake can force the female body into starvation mode. This mode involves the shutting down of all the non-essential survival functions. Not having a period for a longer time is not healthy. The absence of menstruation can occur for several reasons, including thyroid problems, stress, certain medications, and brain tumors. The symptoms are excessive thirst, large thyroid, darker skin, headaches, nausea, swollen breasts, increased hair growth, acne and vaginal dryness.

Extreme dieting or disordered eating can cause sudden weight loss and a decrease in your body fat, which lowers your estrogen levels. Not taking on enough healthy food deprives the body of nutrients that are required to make sex hormones.


You’ve learned about the incredible benefits of a low-calorie diet: weight loss, blood pressure reduction, diabetes prevention, cancer-fighting properties, and even neurological and cardiovascular disease protection. However, it’s crucial to be cautious with very low-calorie diets to avoid issues like constipation, fatigue, muscle loss, and menstrual irregularities.

Now that you understand the power of a low-calorie diet, why not start incorporating more nutrient-dense, low-calorie foods into your meals? Remember, small changes can lead to significant results in your health journey. Take charge of your well-being by making informed choices and embracing a balanced approach to nutrition. Your body will thank you for the care and attention you give it!


Is a low-calorie diet effective for weight loss?

Yes, a low-calorie diet can be effective for weight loss as it helps create a calorie deficit, leading to the burning of stored fat for energy. However, it’s essential to ensure you’re still getting all the necessary nutrients.

Will following a low-calorie diet help prevent diabetes?

Following a low-calorie diet may help prevent diabetes by promoting weight loss and reducing insulin resistance. By maintaining a healthy weight and blood sugar levels, you can lower your risk of developing type 2 diabetes.

Can a low-calorie diet contribute to muscle loss?

A very low-calorie diet without sufficient protein intake or exercise can lead to muscle loss. To preserve lean muscle mass while on a low-calorie plan, focus on consuming an adequate amount of protein and incorporating strength training exercises.

How does a low-calorie diet impact fatigue levels?

Initially, when transitioning to a low-calorie diet, you may experience fatigue due to reduced caloric intake. This adjustment period is temporary as your body adapts to using stored energy sources more efficiently. Ensuring proper hydration and nutrient intake can also help combat fatigue.

Does following a very low-calorie diet increase the risk of constipation?

A sudden drastic reduction in calories from very low-calorie diets coupled with inadequate fiber intake can lead to constipation in some individuals. It’s crucial to include fiber-rich foods like fruits, vegetables, and whole grains, and stay hydrated while on such diets.
