Adherence
Long-term use of structured meal replacements (one meal and one snack daily) significantly improves weight maintenance and metabolic biomarkers (blood pressure, triglycerides) compared to conventional energy-restricted diets in obese patients.
To maintain weight loss long-term, use a structured meal replacement plan. Replace one meal and one snack daily with fortified shakes or bars, and eat one balanced whole-food meal. This structure reduces decision fatigue and improves metabolic health (blood pressure, triglycerides) more effectively than standard calorie counting alone. Expect to lose about 8% of body weight over 4 years with this approach.
Providing a structured meal plan via vitamin- and mineral-fortified liquid meal replacements is a safe and effective dietary strategy for obese patients. Long-term maintenance of weight loss with meal replacements can improve certain biomarkers of disease risk.
Why this rating
Randomized controlled trial with a long follow-up (4 years), though with significant attrition (25% dropout).
