Very low-calorie diets VLCDs offer an aggressive approach for rapid weight loss. For individuals with BMI over 30 obese, VLCDs are typically effective, enabling the loss of about 3 to 5 pounds per week over a period of 12 weeks or less, ming for an average total weight reduction of approximately 44 pounds. This significant drop in body mass can help improve health conditions related to obesity such as diabetes, hypertension, and high cholesterol.
However, VLCDs may not prove superior in the long term compared to more moderate diet plans. Once a person completes such a diet program, they must adapt their lifestyle with healthy eating habits and regular physical activity for sustned weight loss mntenance.
The use of very low-calorie diets is generally considered safe under medical supervision for individuals with BMI greater than 30 obese. For those with a BMI between 27-30 overweight, VLCDs should be reserved for those facing weight-related health issues and are medically monitored.
These diets are not advised for pregnant or lactating women, children, or adolescents except in specialized programs. They may also pose risks for individuals over age 50 due to potential medication needs and side effects associated with rapid weight loss.
Individuals on VLCDs might experience minor side effects such as fatigue, constipation, nausea, and diarrhea when using them for durations of 4 to 16 weeks. These conditions usually improve within a few weeks but may occasionally limit people's ability to complete the program.
Gallstones are among the most frequent serious complications associated with very low-calorie diets. The formation of gallstones can occur due to increased cholesterol production by the liver as it breaks down stored fat for energy during calorie deficits.
Very low-calorie diets may not meet nutritional requirements necessary for optimal health, which is crucial considering their potential lack of full satiety and energy levels. Dly activities and regular physical exercise can become challenging on these diets, especially when consuming the same foods repeatedly.
It's advisable to consult with a healthcare provider or dietitian before embarking on any very low-calorie diet plan to ensure you receive sufficient nutrients while adhering to such stringent caloric intake.
