As I've known it it's not really a ketogenic diet if your taking in >20g carbs per day. > Ketogenic diets can induce weight loss (20–23). In a 2020 meta-analysis of 38 studies lasting 6–12 months and including 6,499 participants, low-carbohydrate diets, defined here as <40% of energy from carbohydrate, led to a small weight loss, compared with low-fat diets, defined as <30% of energy from fat (mean difference −1.30 kg; 95% CI, −2.02 to −0.57), with considerable variability between individuals and between studies. More than half of included studies met criteria for a general ketogenic diet, as defined in Table 1, for part or all of the low-carbohydrate intervention (24). Even `classic keto` as defined in their table allows for 10% of your calories from carbohydrates. If eating 2kcals/day, that's 50g of carbs. In no way do the studies referred match what I've known as keto. The goal to me is accidental carbohydrates only.

Plenty of studies on ketogenic diets on rats are based on adding an incredible amount of fat on top of carbohydrate heavy and call it ketogenic. /r/ketoscience has these crappy studies posted and debunked daily. Serious research on low carb is sorely lacking and plenty of interested parties really do not want for good science to be done around high fat/meat: the money's on plant based these days. I am still salty about that sorry excuse for a study the Lancet posted a few years ago and is still making headlines.

<20g is just the threshold that's guaranteed to put most people into ketosis, but the exact number will vary by person. <50g is also a common threshold that works for many people. I'm not an expert on what qualifies as a "ketogenic diet" but personally I would say that if your diet consistently leaves you in a state of ketosis, then it's ketogenic. I would hope that any study on ketogenic eating is actually measuring blood ketones to determine this.

Later on in the paper, they rely on a bunch of trials and specify a low-carb diet as <130g per day! Yeah, I never see a good analysis of a strict keto diet... First two weeks are incidental carbs only, as close to 0 as possible.. after that maybe 20 a day, 30 a day, for months. I'm on day 56 right now and down 21 pounds.
