Real World Adherence to a Severely Energy Restricted Meal Replacement Diet in Participants with Class II and III Obesity

Severely energy-restricted diets (SERDs) are an effective treatment for obesity, however, adherence to such is often perceived as poor by healthcare professionals. This investigation evaluated a 12-week SERD in participants with class II and III obesity. Reported food consumption was compared against individualised prescriptions. Body weight measures were obtained at baseline, 12 52 weeks. The data analysed three groups (i) the entire cohort (n = 26), (ii) completers 13) (iii) non-completers 13). prescription elements included number of meal replacement products; total protein; energy intake; (iv) level dietary restriction; (v) vegetable serves; (vi) water serves, (vii) how much physical activity performed. A generalised repeated-measures mixed-effects model used investigate if program individually, or collectively, influenced loss. Completers had average (± SD) 4549 ± 748 kJ intake per day, resulting mean restriction 62% 69% prescribed, indicating degree non-adherence. percent changes −7.8 4.7% −1.6 2.6% weeks, −12.2 12.1% −1.8 3.2% respectively. Complete may not be necessary achieve clinically relevant loss 12% restricted least (~4600 day) relative requirements.
