Intermittent vs continuous VLCD therapy in obesity treatment

Area of Science:

• Nutrition Science
• Obesity Management

Background:

• Very low calorie diets (VLCDs) are used for obesity treatment.
• The efficacy of intermittent VLCD regimens has been understudied.
• VLCD programs can be implemented with limited medical resources.

Purpose of the Study:

• To compare the effects of continuous versus intermittent VLCD treatment on weight loss and compliance.
• To evaluate intermittent VLCDs as a potential therapeutic tool in obesity management.

Main Methods:

• Two studies involving 40 and 61 obese patients (BMI ~39 kg/m2) were conducted.
• Patients received either continuous or intermittent (3 x 2-week periods with 4-week intervals) VLCDs (420-530 kcal/day).
• Attrition and weight loss were assessed at 14 and 26 weeks.

Main Results:

• Weight loss and patient attrition were similar between continuous and intermittent VLCD groups at both 14 and 26 weeks.
• Intermittent VLCD treatment demonstrated comparable long-term weight loss and compliance to continuous VLCD therapy.
• Individual patient factors, such as side effects and motivation, may influence treatment preference.

Conclusions:

• Intermittent VLCD therapy is a feasible and effective strategy for long-term weight management in obese individuals.
• This approach may offer an alternative for patients who experience side effects or prefer flexible treatment schedules.
• Intermittent VLCDs represent a valuable addition to the therapeutic options for obesity, particularly in resource-limited settings.
