Total Diet Replacement (TDR) using meal replacements in very-low-calorie diets (VLCDs) produces significantly greater weight loss (average >10 kg over 12 months) and superior diabetes remission rates compared to usual care or food-based diets.
If you have obesity or Type 2 Diabetes, using Total Diet Replacement (TDR) with meal replacements for 3-5 months, followed by maintenance with 1-2 meal replacements daily, is a clinically proven strategy. It leads to significantly more weight loss (average 10kg+) and higher diabetes remission rates than standard advice. Ensure you work with a healthcare provider for medical supervision, especially during the initial very-low-calorie phase.
Several clinical guidelines have endorsed the use of MRs as a part of MNT for obesity, primarily based on evidence that shows an average weight reduction of −10 kg or more with TDR over at least 12 months in large, randomized controlled trials. When compared to usual care controls, these effects are 6–8 kg greater, and when compared to food-based diets, the effects are nearly twice the effect of a food-based diet.
Why this rating
