Does Calories-In and Calories-Out work on Keto? In the last 162 days I have averaged 2391 calories a day. My weight is the same at the end of these 162 days. My total energy expenditure (TDEE) is calculated at 2232 calories a day. This is only 159 calories a day from my TDEE or 7% off the calculated amount and that’s less than half the assumed measurement error in the food (typically assumed to be 15%).
So, yes, I conclude that Calories-In and Calories-Out do fairly closely match. At least in my particular case and macros.
So Why Keto?
Where Keto comes in is that I have maintained a 120 lb loss for the past 5+ months without hunger. My hormones are in balance. My insulin level is kept low. I don’t have the blood sugar roller coaster ride.
…average daily energy expenditure of traditional Hadza foragers was no different than that of Westerners after controlling for body size.
The metabolic cost of walking (kcal kg−1 m−1) and resting (kcal kg−1 s−1) were also similar among Hadza and Western groups. The similarity in metabolic rates across a broad range of cultures challenges current models of obesity suggesting that Western lifestyles lead to decreased energy expenditure. We hypothesize that human daily energy expenditure may be an evolved physiological trait largely independent of cultural differences.
total protein amount should be spread out over 5 to 6 intakes a day
They advise the amount of protein to be:
For males, who aim at increasing muscle mass and strength gains, if you only train once a day, 2 g a kg should be more than enough (for women 1.2g /kg of bodyweight).
Let’s do the math here. Suppose someone is 75 kg (about 165 lbs). At 2g/kg that would be 150 grams of protein per day. If they eat 5 meals a day that would be 30 grams of protein per meal. The problem is that they will probably not ever reach the Leucine threshold at any of the meals (Protein Gurus – Part 2). As a result they will never maximize muscle protein synthesis.
Also the timing between protein meals should be 5 hours and that would be 25 hours of eating in a day. Doesn’t quite fit.
Jimmy had Keto Savage, Robert Sikes, on his podcast (19: The 90 Percent Fat Hack Protocol With Robert Sikes). Jimmy called him a nutritional expert (@4:20, 4:50). I have nothing against being self-taught on nutrition – that’s what I am. But I don’t think that Keto Savage is a nutritional expert. He is a body builder who does Keto. The thing I like best about Robert is that he publishes what he eats and his results even if they contradict the keto narrative. He doesn’t cherry pick through the data.
One thing that Jimmy could learn from Keto Savage is Robert’s own 4,000 calorie fat challenge. Robert went on a 2 month diet with low carbs and high fat and took his body fat from around 4% to 10%. If you are not used to looking at body fat numbers he went from very low to less low. I wrote about Robert’s test (Does Fat Make You Fat?).
To Robert’s credit he tried to do his best with Jimmy’s request since he viewed Jimmy’s calorie choices as too low on the low fat diet.
I’ve been collecting studies for a while and hosting them on GitHub at OpenKeto/KetoStuff. Here’s the structure of the studies.
Some of the studies can be put into multiple places so I picked one or the other place to put them without much pattern as to why. Classifying the LC Diet as Energy Input is possibly the key insight into this pattern. Also, the Effect of the Ketogenic Diet on Diabetes is under MetS.
With GitHub Desktop you can replicate the entire repository onto your computer or select individual files to download. Copyrights are the individual holders. Studies are reproduced here and were found on the Internet in general.
The purpose of this study was to examine the effect of alterations in diet composition on energy expenditure and nutrient balance in humans. Eight adults (three men, five women) ate a high-carbohydrate (60% of calories from carbohydrate) and a high-fat (60% of calories from fat) diet for 7 d each according to a randomized, crossover design. Six subjects were studied for an additional week on a mixed diet (45% of calories from fat).
For each subject, total caloric intake was identical on all diets and was intended to provide the subject’s maintenance energy requirements.
All subjects spent days 3 and 7 of each week in a whole-room indirect calorimeter.
Diet composition did not affect total daily energy expenditure but did affect daily nutrient oxidation by rapidly shifting substrate oxidation to more closely reflect the composition of the diet.
You can burn more fat and not lower your metabolism on a lower carb diet.
I wanted to export my data from my macros tracking program, Cronometer. How to export data is not exactly hidden but it’s not obvious either. Under Profile, Account Information, Select the gear then Export Data…
You then get the options as follows:
Select the timeframe you want to look at. You can export all data if you want. You can then export the servings, exercises, biometrics (weight if you have a linked device) or things you have entered, and any notes. The output file is a CSV which can be opened by any spreadsheet program.
I like to rename the file something like: “servings-2018-05-19.csv” since Cronometer just gives the file(s) the generic name “servings.csv”. You can then open the file(s) with EXCEL or Open Office or Libre Office. Here’s what the start of my file looks like:
I listen to quite a few Keto Podcasts. They can be informative and in some cases entertaining. Here’s some of them.
The Paleo Solution Podcast – It might seem like an odd first choice but I really like Robb Wolf’s style. He’s one smart paleo cookie. He has quite a bit of keto content and has done keto for much of his adult life.
2 Keto Dudes – There’s a lot to like with these two software developers turned keto dudes. They’ve had a similar journey to mine with overcoming Type 2 Diabetes and their interview format is flexible enough for them to have guests that aren’t exactly in line with their higher-fat views. I’d like to see these guys get closer to goal weight but their reluctance to do Protein Sparing Modified Fasts (PSMF) is really slowing down their progress.
Keto for Normies – Her voice can be grating and his can sound like a meathead but their hearts are in the right place. They aren’t afraid to try things like PSMF or Carnivore and report on their successes or failures.
The same sets of guest often make the rounds on each of these shows. They all seem to have the same list of keto guests such as Dave Feldman (Cholesterol Code), Marty Kendall (Optimising Nutrition), Shawn Baker (Carnivore Diet), Ted Naiman (Burn Sugar Not Fat), Robert Sikes (Keto Savage), Luis Villasenor/Tyler Cartwright (KetoGains). It does also entertain me that the podcasters often interview other podcasters.
I haven’t deliberately omitted any podcasts that I know of. There’s some I have not listened to yet so if I find a new one, I will add it to this list.
There’s a belief in the Low Carb community that fat doesn’t make you fat. And to some extent there’s some truth in that. Most people are fat not because of the fat in their diet but because of the carbs in their diet. Here’s a typical infographic used by the Low Carb community which illustrates the point.
Some people, myself included, have done experiments where we ate thousands of calories of fat for days or weeks and have seen little to no weight gain. However, there’s often not much data on the diet selected or timing windows. Did these people eat in a time restricted window?
Keto Savage n=1
Keto Savage did a two month challenge where he ate 4,000 calories of the keto diet. That was 350g of fat a day. He went from 4.3% body fat to 10.1% body fat in those two months.
He best part is that he logged his food and made videos as he went along. It is important to note that he did this “experiment” after he was on a weight cut for a bodybuilding show so he would have been at a reduced body fat level to begin with.
So, yes. Fat can make you fat – even on a Low Carb diet. It takes a lot of work, but it can.
