- "The four diets [1] also allowed for a dose–response test of carbohydrate intake that ranged from 35 to 65% of energy."
A keto diet is "5-10%" carbs, so that's a very significant difference. I doubt you could get into ketosis with a 35% carb diet and they didnt even bother measuring ketosis since there wasn't actually a specific low-carb group.
- "Carbohydrate-rich foods with a low glycemic index were recommended in each diet."
Always good but a recommendation is super difficult to do in practice unless you rigidly sequester carbs youre going to fail. Other keto studies provided the actual food, these people were just given percentages.
Finally the low fat vs high fat not making a difference is actually still in line with Keto diets. The idea is you shouldn't overly worry about fat content. So even if high fat did nothing for weight loss that's not a problem.
[1] The diet groups (note how none are low carb):
- Low-Fat, Average- Protein Group (N = 204) = 65% carbs
- Low-Fat, High-Protein Group (N = 202) = 55% carbs
- High-Fat, Average- Protein Group (N = 204) = 45% carbs
- High-Fat, High-Protein Group (N = 201) = 35% carbs
