I dunno if that is a fair criticism.
Dunno
As you stated, you dunno know.
The reality is nor do many other.
athletes without insulin sensitivity problems he doesn't recommend keto in instead recommends a diet containing carbs.
Insulin Sensitivity
Insulin Sensitivity individuals are fine with a higher carbohydrate diet.
As per D'Agostino, "You wouldn't want to put a most teenage on a Ketogeinic Diet because their body is efficiently running off glucose and carbohydrates..." (4:50 minute mark)
D'Agostino: The Ketogenic Diet for Athletes
"The Ketogenic Diet offers so many advantages to an athlete and
especially and aging athlete..." (4:35 minute mark)
it can certainly be done. If you have enough protein and excess calories (but not too many) and are working out properly you will gain muscle.
Knowledge
This take us back to the issue that very few individual understand how to make it work.
That in part due to the lack of research and data on how to make it work.
The majority of individual go on what they believe is a Ketogenic Diet. However, they are usually on a High Protein, Low Carbohydrate, Moderate Fat Diet.
As you should know, if Protein intake is too high, it is converted to glucose (glyconeogenesis).
Secondly, they are not consuming enough fat.
Thus, they are end up never being in Ketosis.
Enough Protein
A well formulated Ketogenic Diet protects Protein from being utilized as energy.
As per Volek and Phinney, higher levels of Leucine are maintaned on a Ketogenic Diet compared to the Standard High Carbohydrate American Diet. That means, not as much Protein is required on a Keto=genic Diet.
Thomas DeLauer
In one of DeLauer's podcast, he provided some of the reserach data that demonstrated the consuming around a gram of Protein per pound of body weight increased muscle mass on a Ketogenic Diet.
The Caveat
The research showed that the key was for that the Protein Intake needed to remain in the 25% or less of Macros to maintain Ketosis.
Fat Intake had to remain at 70% plus of Macro Intake. In the research study DeLauer went into, Fat Intake was closer to 80%.
That means calories increased!
200 lb Athlete Example
1) 200 gram of Protein (800 kcals per day)
2) 249 gram of Fat (2240 kcals per day or more) would be 70%/
3) 285 gram of Fat (2565 kcals per day) would be 80%.
Protein Intake Confusion
One of the primary issues is indivdiual incorrectly assume that the amount of Protein consumed on a High Carbohydrate Diet is the same amount of Protein needed on a Ketogenic Diet. I went down that road, as well.
The Upside Down Ketogenic Diet
The Ketogenic Diet turns the food Pyramid and everything else upside down.
What applies for High Carbohydrate Athletes/Individuals isn't the same for Ketogenic Diet Athletes.
That applies to...
1) Amount of Protein Intake
Ketones protect and insulate Protein from being used a fuel.
Intermittent Fasting work in using Ketones for fuel. Research has demonstrated that Muscle Mass is protected and perserved with a Fast of up to 72 hours.
2) Training Programs
I have explained this (ad naseum) regarding how to write and perform a Ketogenic Diet Training Program based on employing the Phosphagen Energy System.
3) Blood Lipid Profile Readings
The Ketogenic Diet modifies Blood Lipid Profile Readings.
a) LDL Readings increase due to the increase in Saturated Fats.
b) HDL Readings often increase. That due to the fact that Saturated Fat increases it, along with LDL.
c) Total Cholesterol Readings increase. That is due to the increase in LDL.
Total Cholesterol is the Sum of LDL + HDL + (Triglycerides divided by 5).
d) Triglycerides dramatically drop. That because Triglyceride Levels are determined by the amount of Carbohydrates consumed.
Cursory Readings
Individual with knowledge on how to read a Blood Lipid Profile of an individual can quickly ascertain health status by looking at HDL and Triglcyerides. These are the only two viable individual numbers that mean anything.
Most Physician are clueless in reading a Blood Lipid Profile with individual on a Ketogenic Diet.
Base On What?
I have provided you anecdotal information based on Bill "Peanuts" West gaining weight/Muscle Mass and Strength by increasing Fat Intakle. drinking Peanut Oil.
I have provided you information on how I gained back 17 lb by following West Method with my "Fat Shots" of MCT:Avocado Oil.
"Your Feeling Don't Matter, The Facts Do".
My issue with the information that it's not complete fact based.
If you perfer believe it, that's fine.
My issue is when individuals continue to perpetuate misleading, misinformation.
The Take Home Message
That is the bottom line. Now let me punctuate it.
It works, for someone
who's knowledgeable on how to make the Ketogenic Diet work and how to train on the Ketogenic Diet.
Unfortunately, very few know how.
As I have noted in multiple post, it took me a year to really understand the Ketogenic Diet.
The majority of individual rarely have enough knowledge to really be on the Ketogenic Diet and most chose not to mantain it long enough to obtain results.
Secondly, the majority of individual don't understand that a different training approach is required on the Ketogenic Diet.
It took me a year of research to to understand that the Ketogenic Diet Athlete/Individual obtains optimal results with a Phospagen Energy System Training Protocol.
Car Analogy
Individuals who go on a Ketogenic Diet without understanding theses caveats are doomed to failure or lack luster results.
Individuals who lack knowlege in this area amount to buying a stand car with a clutch, when they don't know how to drive.
Not Optimal
Most individual who try something new (Training Program or in this case the Ketogenic Diet, etc) don't know what they are doing. There is a learning curve to anything new.
What most of these individual do is blame that program rather than accept the fact that they may have inputted it incorrectly.
If something has worked for other and isn't working for someone trying that program, the questions should be...
What are they doing that I am not doing?
What do I need to do to make it work for me?
