I looked earlier (Glycogen Stores – Why does it matter?) at this study (K J Acheson Y Schutz T Bessard K Anantharaman J P Flatt E Jéquier. Glycogen storage capacity and de novo lipogenesis during massive carbohydrate overfeeding in man. The American Journal of Clinical Nutrition, Volume 48, Issue 2, 1 August 1988, Pages 240–247). The purpose of the study was to look at body glycogen stores. As part of the study they compared several diets. These diets were performed as a glycogen depletion/repletion strategy. The study shows the relatively short term weight loss on each diet (Low Carb High Fat, [overfed] High Carb Low Fat, and Protein Sparing Modified Fast diets).
Mean body weight decreased by 0.8 ± 1.4 kg during the 3 d on the restricted, high-fat, low-carbohydrate diet. After the 7 d of overfeeding the high-carbohydrate, low-fat diet (day 10), body weight had increased by 4.6 ± 1 .3 kg (ie, 5.6, 4.9, and 3.2 kg). During the 2 d on the restricted high-protein, low-energy diet (600 kcal/ d) 4.4 ± 0.9 kg were lost.
PSMF for the win!
