Quantities according to the CSIRO team
Very low-carb or ketogenic diet = 20-50g a day
Low-carb = 50-130g a day
Moderate-carb = 130-230g a day
High-carb = 230g or more a day
COMPARING THE DIETS
Comparison of low-carb diets requires research, with some counts including subtractions for fibre, and “bootcamp”
periods ranging from two to six weeks, but in a nutshell:
THE CSIRO LOW-CARB DIET
Starts with 50g carb a day, increasing to 70g over 12 weeks. Most foods retained, with fibre from some bread and grains, but not pasta.
THE ATKINS DIET
A strict four-phase plan developed about 40 years ago, starts with at least two weeks on less than 20g carbs a day if you have more than 7kg to lose.
Allows 30-40g “net” carbs a day, which is carbs minus the fibre count, gradually increasing after weight loss.
THE PALEO WAY (PETE EVANS)
A paleolithic or hunter-gatherer diet that begins with a 10-week program based on low-carb and organic foods.
THE DUKAN DIET
A strict “attack” phase, 1-7 days, where even salad vegetables aren’t allowed. Unlimited lean protein, plus 1.5 tbs oat bran per day. Carbs slowly introduced over three more phases.
