Very Low Energy Diets: Understanding the Risks and Benefits

A very low energy diet (VLED) is a diet plan that restricts daily calorie intake to 800 calories or less. These diets are often used for rapid weight loss, but they can also have serious side effects.

What are VLEDs?

VLEDs are a type of crash diet that can be dangerous if not carefully monitored by a healthcare professional. They are typically used for short-term weight loss, usually for a period of 12 weeks or less. VLEDs are often used for people with obesity or those who have not been successful with other weight loss methods.

Pros of VLEDs

• Rapid weight loss⁚ VLEDs can cause significant weight loss in a short period of time. This can be motivating for people who are struggling to lose weight.
• Increased awareness of food and nutrient intake⁚ VLEDs can help people become more aware of their eating habits and the nutritional content of their food.
• Possible increased satiety and decreased hunger between meals⁚ Some people find that VLEDs help them feel fuller for longer, which can make it easier to stick to the diet.
• Restrictive nature of diet usually encourages more home-cooked meals⁚ Because VLEDs are so restrictive, they may encourage people to cook more meals at home, which can be healthier than eating out.

Cons of VLEDs

• Rapid weight loss might initially come from water losses and may not be indicative of true weight loss⁚ VLEDs can cause rapid weight loss, but much of this is due to water loss. This is not sustainable weight loss.
• Keto flu⁚ VLEDs can cause a range of side effects, including fatigue, headaches, constipation, nausea, and diarrhea. These symptoms are often referred to as the "keto flu" because they are similar to the flu.
• Nutrient deficiencies⁚ VLEDs can lead to nutrient deficiencies because they are so restrictive. This can cause a range of health problems, including fatigue, hair loss, and brittle nails.
• Gallstones⁚ VLEDs can increase the risk of gallstones, which can cause abdominal pain and require surgery.
• Cardiovascular problems⁚ VLEDs can also increase the risk of cardiovascular problems, such as heart attack and stroke. This is because they can lower blood pressure and increase the risk of arrhythmias.
• Metabolic slowdown⁚ VLEDs can slow down your metabolism, making it harder to lose weight in the long term. This is because your body adapts to the reduced calorie intake and starts burning fewer calories at rest.
• Eating disorders⁚ VLEDs can be a trigger for eating disorders. This is because they can lead to unhealthy eating habits and a preoccupation with food and weight.
• Unsustainable⁚ VLEDs are not sustainable in the long term. This is because they are very difficult to follow and can lead to nutrient deficiencies and health problems.
• Muscle loss⁚ VLEDs can cause muscle loss because they do not provide enough protein. This can make it harder to maintain a healthy weight and can also lead to weakness and fatigue.
• Increased risk of death⁚ Unmonitored VLEDs with insufficient or unbalanced nutrients can cause sudden death by cardiac arrest either by starvation or during refeeding.

Safety Considerations

VLEDs are not suitable for everyone. They should only be used under the supervision of a healthcare professional. If you are considering a VLED, it is essential to talk to your doctor first. They will be able to assess your individual needs and risks and determine whether a VLED is safe for you.
