The truth and facts about protein

becoming_a_new_me

I'm actually dropping this subject - those of you responding will find a way to poke holes into everything I say. Again...I use words such as "may" and "could be". You quote bodybuilding magazines and personal trainers. Lets agree to disagree and hopefully you people will realize that you are the 1% of the weight loss crowd. The normally active person does not need to overdose on protein.

I'm not a bodybuilder by any means, and I consume more than 30% protein some days. I guess I'll just wait to see if I keel over

I stand by my previous statement of : "I do notice that the people who have a problem with this data are bodybuilders, muscle-bulking, or are heavily athletic. This blog was not geared towards those people. The "average" person is who this was geared towards, and is factual. I even had my doctor read the information, and he agrees that for the normal person, the data is sound."

Obviously then, you may need to update your blog to include all demographics, if your just going to say that you stand by what you say . I suspect some of the people your referring to, do actually exercise with varying degrees of intensity and type, no?Maybe they're all couch potato's but somehow I suspect they're not. For protein I suggest you look at some of the papers by Dr Peter Lemon, for starters, doesn't get much better than that and you will not only be helping yourself but the people that read your blog.

The normal weight loss person is not a couch potato, nor are they extreme. A high-end of 30% is perfectly acceptable and safe for the layperson. Most information that I have seen points to potential dangers of a long-term high-protein diet, so I am not going to modify the blog to conform to a few minority to do not subscribe to mainstream facts. I will put a disclaimer that the information contained is for the average person, and anyone who is under a doctor's care should listen to the physician. I won't condone excessive-protein diets because a half a dozen of you feel free to attack the facts. We could get into a p!ss!ng contest all day, but what it boils down to is the typical person can benefit from the facts.

Protein requirements shouldn't be based on a percentage, but on lean mass. I'm sure we would all loike to see these long term high protein diet dangers, actual studies I mean, seriously i don't mean to be rude.

Assuming that this person is under a 2400 calorie per day diet, then the high end of 30% would be 180g of protein. Therefore your Dr. Lemon is actually making the same recommendations that I did in my blog.

Actually your blog says that for a 180 lb person that they should eat 8'gs of protein for every 20 lbs of body weight which is 72g....big difference I would say

You're right no one needs to OD on protein, however it will not harm them like you said it will. You seemed to have glossed over everything i have posted, which was not quoting bodybuilding mags or trainers. Also you may have no idea what you're talking about and you could be using crappy sources to base your information on

In another thread you said you work in the nutrition field, may i ask what it is you do in the field of nutrition?

Is there one peer reviewed study in all of those links are those just articles? I mean, seriously. Bodybuilding.com has a ton of mis-information articles on their main site. Not sure why, but everyone knows this already.

Everyone seems to think so. My doctor actually told me that she would not give me detailed nutrition advice because she di not know. I respect her so much!

I am a nutrition major and am confused at where a lot of these "truths" come from. We sure aren't taught that here o.O

The title should actually be: "Made up **** about protein"

I'm actually dropping this subject - those of you responding will find a way to poke holes into everything I say. Again...I use words such as "may" and "could be". You quote bodybuilding magazines and personal trainers.

Your detractors quoted peer-reviewed science. You quoted websites and lay-articles.

Which do you think is the better source?
