Energy balance

The 5:2 total diet replacement (5:2TDR) resulted in a weight loss of -0.9 kg after 26 weeks, while the once-daily meal-replacement (DMR) group experienced a weight regain of 3.5 kg, leading to a between-group difference of -4.4 kg.

Practitioners may consider recommending 5:2TDR for better weight maintenance outcomes compared to DMR.
