🥦 A Comprehensive Overview of Very-Low-Calorie Diet 🍎
Greetings to all health enthusiasts out there! In this journal article, we will explore one of the most popular yet controversial diets out there – the very-low-calorie diet. This type of diet involves consuming a significantly reduced number of calories per day, typically between 500 to 800 calories per day. Despite its popularity, very-low-calorie diets are often misunderstood and criticized for their risks and effectiveness. In this guide, we will provide all the necessary information to help you make an informed decision about whether a very-low-calorie diet is right for you or not.
What is a Very-Low-Calorie Diet?
A very-low-calorie diet (VLCD) is a weight-loss diet that restricts calorie intake to an extreme level, usually between 500 to 800 calories per day. This is significantly lower than the recommended daily calorie intake for an adult, which is around 2000 calories per day for women and 2500 calories per day for men. The goal of a VLCD is to induce rapid weight loss by putting the body in a state of ketosis, where it burns fat instead of glucose for energy.
How Does Very-Low-Calorie Diet Work?
When you consume fewer calories than your body needs to function, it will start breaking down stored fat to use as energy. This state is called ketosis, and it is the primary mechanism behind very-low-calorie diets. Instead of relying on glucose from carbohydrates, your body will start using ketones from fat for energy. This results in rapid weight loss, often up to 5 pounds per week, depending on the individual.
Benefits of a Very-Low-Calorie Diet
There are several potential benefits to following a VLCD, including:
|VLCDs can help you lose weight rapidly, which can be beneficial for people with obesity, type 2 diabetes, or high blood pressure. Rapid weight loss can also be motivating and lead to long-term weight loss success.
|Improved Blood Sugar Control
|VLCDs can improve blood sugar levels in people with type 2 diabetes by reducing insulin resistance.
|Reduced Risk of Heart Disease
|VLCDs can improve several heart disease risk factors, such as high blood pressure, high cholesterol, and high triglyceride levels.
|Improved Mental Clarity
|Some people report improved mental clarity and focus when following a VLCD.
|Reduced Joint Pain
|VLCDs can reduce joint pain and inflammation, especially in people with osteoarthritis.

While very-low-calorie diets can provide rapid weight loss and other potential health benefits, they also come with several risks and potential side effects. Some of these risks include:
- Malnutrition and nutrient deficiencies
- Gallstones and other digestive issues
- Electrolyte imbalances and dehydration
- Muscle loss and decreased metabolism
- Rebound weight gain
- Increased risk of eating disorders

FAQs About Very-Low-Calorie Diet
1. Is a very-low-calorie diet safe?
While very-low-calorie diets can provide rapid weight loss, they also come with several risks and potential side effects. It is essential to speak with a healthcare provider before starting a VLCD to determine if it is right for you and to monitor your health throughout the diet.
2. Can a very-low-calorie diet lead to long-term weight loss?
While VLCDs can provide rapid weight loss, the key to long-term weight loss success is sustainable lifestyle changes that include regular exercise and a healthy diet. Studies have shown that most people who lose weight rapidly on a VLCD end up regaining most or all of the weight within a few years.
3. What can I eat on a very-low-calorie diet?
Most VLCDs involve consuming meal replacement shakes, bars, or soups, as well as small portions of low-calorie vegetables and lean protein. The specific foods you can eat may vary depending on the diet plan and your healthcare provider’s recommendations.
4. How long can I follow a very-low-calorie diet?
Most VLCDs should not be followed for longer than 12 weeks at a time, and they should always be supervised by a healthcare professional to monitor for potential side effects and complications.
5. Can I exercise on a very-low-calorie diet?
While exercise is encouraged, it is essential to be cautious and not overdo it on a VLCD. Vigorous exercise can be challenging on a low-calorie diet and may cause fatigue, dizziness, or other side effects. Speak with a healthcare provider before starting an exercise program while on a VLCD.
6. Can a very-low-calorie diet cure type 2 diabetes?
While VLCDs can improve blood sugar control in people with type 2 diabetes, they are not a cure. Sustainable lifestyle changes that include regular exercise and a healthy diet are necessary for long-term blood sugar control and overall health.
7. Can I follow a very-low-calorie diet if I am pregnant or breastfeeding?
No, VLCDs are not recommended for pregnant or breastfeeding women as they can lead to malnutrition and other complications for both the mother and the baby.
8. Can a very-low-calorie diet cause hair loss?
Yes, rapid weight loss can cause hair loss as it can disrupt the normal growth cycle of hair. However, this is typically temporary, and hair will regrow once weight loss stops or when nutrient deficiencies are addressed.
9. Can a very-low-calorie diet cause constipation?
Yes, a low-fiber diet can lead to constipation, which is a common side effect of VLCDs. Drinking plenty of water and consuming low-calorie, high-fiber foods such as vegetables can help prevent constipation.
10. Can a very-low-calorie diet cause muscle loss?
Yes, consuming very few calories can cause muscle loss, which can decrease metabolism and make it harder to lose weight in the long run. However, incorporating regular exercise and consuming adequate protein can help preserve muscle mass during a VLCD.
11. Can a very-low-calorie diet cause gallstones?
Yes, rapid weight loss can increase the risk of developing gallstones, which are small stones that form in the gallbladder. To prevent gallstones, it is essential to drink plenty of water, incorporate healthy fats into your diet, and avoid rapid weight loss.
12. Can I drink alcohol on a very-low-calorie diet?
Alcohol should be avoided or consumed in moderation on a VLCD, as it provides empty calories and can interfere with weight loss and health goals.
13. Can a very-low-calorie diet cure sleep apnea?
While VLCDs can lead to weight loss, they are not a cure for sleep apnea. Sustainable lifestyle changes that include regular exercise and a healthy diet can help improve sleep apnea symptoms and overall health.
The Bottom Line
Very-low-calorie diets can provide rapid weight loss and potential health benefits, but they also come with several risks and potential side effects. Before starting a VLCD or any weight-loss program, it is crucial to speak with a healthcare provider to determine if it is safe and appropriate for you.
