High Fat v. High Carb & Physical Performance


#1

It failed to show when I posted it as a Word document. I will try it in PDF.


#2

Didn't work again. Forget about it.


#3

So I have included some studies to look at because I can't show my chart.

I have more, but am only reviewing those published after 1999 for this report (aside from the work of Dr. Phinney which I've included in a conclusion and introduction).

NO bro science here.

open this file on your computer, make the chart large, then use the screenshot command and upload the screenshot...you computer illiterate babbling dietician!


#5

I still can't figure it out.


#6

So what's the bottom line? The suspense is killing me.


#7

Is this your thesis bro? Cool - I want to read it. : )


#8

They are most of the references for the thesis report. I will share with you when we get in touch or via email.

I just wanted to share the chart I made.

PCDude: The verdict? I don't know; I haven't thought of or written my conclusion or read other review studies. I'm doing that this week. These studies are only on endurance athletes (triathletes, duathletes, cyclists, rowers, and runners), and the study protocols vary widely (training schedules, performance trials and diets). Some of the diets are up to 65% fat and up to 75% CHO, which I don't like. Then again, this review is not about what I like and dislike for the most part.


#9

Raj: Can I email it to you and you put it in screenshot?


#10

just push the print screen button, open up MS paint then ctrl+V (paste) and there's your screenshot.


#11

What Waylander said, but if you're still confused I'll PM you my email just in case


#12

If you're on a mac the printscreen command is Command+Shift+3


#13

Thank you. Please send. I don't do PMs anymore on my part though. You can email me with my contact info for my email address and FB information in my hub.

I tried what Way said, but it didn't work.


#14

I'm on a PC.
