Diets with high or low protein content and glycemic index for weight-loss maintenance.
In this large randomised controlled trial it was found that a modest increase in dietary protein and a modest reduction in dietary glycemic index led to an improvement in the study completion and maintenance of weight loss. Larsen et al. N Engl J Med. 2010 25;363(22):2102-13.
Glycemic index and satiety: A systematic review and meta-analysis.
This systematic review and meta-analysis provides high level evidence from randomized trials in humans that low GI foods or meals are more satiating than high GI foods, meals or diets. Talya Postelnik, Alan W Barclay, and Peter Petocz. GI Foundation, 2015 – See GI & health claims
Effect of the glycemic index of the diet on weight loss, modulation of satiety, inflammation, and other metabolic risk factors: a randomized controlled trial.
A low GI and energy-restricted diet containing moderate amounts of carbohydrates may be more effective than a high GI and low fat diet at reducing body weight and controlling glucose and insulin metabolism. Juanola-Falgarona M et al, Am J Clin Nutr. 2014 Jul;100(1):27-35
Low glycaemic index or low glycaemic load diets for overweight and obesity:
This Cochrane Review (systematic review and meta-analysis) found that lowering the glycemic load of the diet appears to be an effective method of promoting weight loss and improving lipid profiles and can be simply incorporated into a person’s lifestyle. Thomas et al. The Cochrane Library 2007, Issue 3
Long-term effects of dietary glycemic index on adiposity, energy metabolism, and physical activity in mice.
The study concluded that in this animal model: 1) the effect of GI on body composition is mediated by changes in substrate (e.g., carbohydrate and fat) oxidation, not energy intake; 2) a high GI diet causes insulin resistance; and 3) dietary composition can affect physical activity level. Pawlak et al. Lancet. 2004; 364(9436): 778-85
