Eating nothing but protein

[Doctor pump]

If I were lifting hard and eating a little over my maintenance level of calories in almost only protein, what would happen. And it would all be natural protein, no supps. So I'd be taking in atleast 350 grams of protein a day and I only weight 130lbs. I already about Carb/Protein/fat ratio's, I just want to know if they are any health or muscle gain concerns with what I want to do???

[XxX-Huynh]

your gonna get protein poision and all that protein wil lgo to waste your body can only digest so much protein at one time

[oatmeal_addict]

350g of protein is only 1400 calories (roughly) good luck gaining mass with this. your body needs carbs, negative side effects of the atkins diest prove this, so eat fat protien and carbs, and lots of them.

[mikeccccc]

it wont hurt u but it is innefective as oatmeal said. U need more total calories!

[JellyBeans]

lol...

[Lintford]

Yeah, 350g protein isnt too much, the ghey boy just listens to his mum too much.

You need carbs and fats too, I would recommend at least another 200g carbs at a very minimum.

[JellyBeans]

350 protein is too much for his bodyweight. Hes only 130 a lot of that protein will turn to fat!

[oatmeal_addict]

most of the protein would be used as a fuel source not building muscle or fat

[concept]

Side effects include but not limite to: constipation, bloating, tiredness, lack of energy, possible liver problem.

[strength+honor]

Like some of the other posters said get more carbs and more fats (good fats thought)...eating that much protein won't have negative side effects but at the same time won't have any positive effects. because your body can only absorb so much protein, the rest of it you will just sh!t out.

[stella summers]

Your main source of energy come from carbs and fats son. So you NEED those.

[Chubba]

You need all macronutrients for a healthy body, disregarding body building... each works to help maintain our physiology...

350 grams is too much for 130lb body. That's nearly 3g per lb.

your glycogen levels are going to suck.
your body can convert protein to glucose and store as glycogen but it definitely isn't optimal. you'll never gain mass without a decent amount of carbs. I'd
say for the absolute minimum of a growth phase have carbs for breakfast, before and after training.

[Cell-Tech]

Vegetables don't do much in terms of calories, but any one who knows about diets won't make one without those.


I'm not gonna type out an essay about it, but you'd be MUCH better off with a variety of foods although you would probably grow if you somehow could take in that much protein and nothing else.

dude you forgot severe yeast infection in the mouth and anus!

[Ruger.22]

Dude, just a protien diet is bad, you need your vietamens.

[justinbrown]

vietamens.

vietnamese vitamins!?

hahaha

Usually only wankers do this, but for the purpose of this thread I'll quote myself. This was a study that I found that I posted in another thread and it just fell to the bottom.

None advocate the
use of a supplement over protein acquired from food. The protein requirement of individuals
undergoing resistance training has been estimated to be 1-1.5 g/kg of body weight/day (1). This
requirement is easily met in a normal balanced North American or European diet, particularly
among athletes due to their increased consumption of food. Both the Tipton et al. and Burke et
al. studies have indicated that increased consumption of protein beyond this requirement is
unlikely to have an additional positive effect on muscle protein synthesis after resistance
exercise. This is most likely because there is a maximal rate of protein synthesis, beyond which
the ingestion of more amino acids will not have an effect. In fact, these extra amino acids would
simply be excreted, and excess protein ingestion therefore has the capacity to place a significant
strain on the kidneys due to the increased concentrations of nitrogen that must be removed from
the body. Therefore, whey and other protein supplements should be taken only if protein intake
from dietary sources is insufficient to meet the increased protein needs of resistance training.

That's roughly 70grams of protein for me, and I weigh nearly 150lbs.

question--i know all about the importance of a balanced diet...and i know that protein is what builds the muscle up and repairs it stronger than before it was broken down.

but here's my question:

when one is bulking, they need an excess of calories. usually its suggested to eat your bodyweight or more in protein, as well as a certain percentage of fats..often around 20%....the rest comes from carbs. so if your muscles need to grow, you can only gain mass by eating excess food, typically carbs. but if protein is what builds muscle, is it true that carbs are building muscle as well?

i was under the impression that protein is the only macronutrient that BUILDS muscle. if the extra carbs one often eats during a bulk (as protein intake often remains constant whether one is cutting OR bulking) are what is adding size, what exactly and how exactly are they adding size. they can refill glycogen stores, sure, but these give the illusion of size and only pump the muscle up and get depleted after a workout. how do the carbs actually build mass overall.

i guess im asking how is it that one CANT eat the excess calories in protein. i suppose theoretically, one could never consume more than maintenance calories, but be eating enough protein to rebuild and repair stronger muscles, but they would never gain weight. their body composition would just continue to change until it hits a point where the body is at an extremely low bodyfat and the body is made up of a ton of muscle. the person would weigh the same as they started, but have insane strength and low bodyfat. at least this is the general idea behind cutting.

but how is it that carbs aid in adding actual mass and size when it is the protein that builds the muscle, which is what we are seeing the size increase in. its not like the carbs are making your organs and tendons larger which is also increasing in size. its just your muscles that are adding weight...the carbs only really add fat. can someone clear this up, my heads spinning!

[slackajack]

Mate, if building muscle is all you want to do, get all your calories from protein. If you want to be healthy and live longer than a few months, eat some carbs.

If you'd read my previous post, the study show's that you need a hell of a lot less protein than most people think. Less than half, infact.


And to answer your question, carbs don't build muscle, but if you don't get enough calories, your body will burn muscle and use up all the protein that you're eating. This is why you need excess calories, and the best way to get these are from carbs and fats (not to mention you need them).

thanks, ur last paragraph explained it to me. just didnt understand the science behind it, although i do eat quite a balanced diet. i still try to eat just my bodyweight in protein...i think im actually around the lesser side of protein intake, considering some people take double or more of their bodyweight in protein g per day. there will always be camps for both sides, so i stay in the middle. i did know that carbs were 'muscle preserving', just didnt put it together that youd need those carbs to do just that, preserve the muscle that the protein rebuilds. thanks for clearing it up again. cheers!

Same as the old liquid protein diets - you would die.

http://charm.cs.uiuc.edu/users/jyelo...ed/topic9.html
Back in the '60s, many people were given a "liquid protein" diet drink to lose weight fast. Many of them died of heart attacks. Eventually, it was discovered that the heart attacks were caused by the lack of vitamins and minerals in the diet drink.

Your main source of energy come from carbs and fats son. So you NEED those.

There are no essential carbs - only essential fatty acids and essential amino acids. However we do need the fibre, vitamins & minerals that come from veges.

[slackajack]

Yeah, it's rediculous how much protein some people take. I don't think twice your body-weight in protein is enough to be too harmful, but I think it's a waste. When you eat too much protein you can smell it in your urine. You just pee it out after a certain amount.

reading this thread I am a hit confused as to how much protein and carbs I should be eating.

For the past year I have been eating 30gms of protein every 3hrs (about 5 meals a day) with a shake after cardio training every second day and as little carbs as possible but plenty of veg and healthy fats

Is this something that would make sense for a bloke who is 160kgs/350lbs and is looking to lose 25kgs/60lbs?

.8g of protein per pound as a minimum, how you get it is up to you and timing is not the most important factor.

That said- for 'optimal' Muscle Protein Synthesis, 4-5 meals per day, with ~30g of protein and 3g of leucine in each is about the best you can do.

[CommitmentRulz]

350 protein is too much for his bodyweight. Hes only 130 a lot of that protein will turn to fat!

If he only eats 350 grams of protein and nothing else, he is getting 1400 calories a day. How is his body going to create fat from excess protein when he is (presumably) burning more calories than that each day?

So you would suggest looking at maybe 40-50gms of protein a meal?

Would not provide any additional benefit, so not really.

A; your energy levels will drop through the floor....you will not be "lifting hard", you will be counting down the sets, cheating on your workouts and finding excuses to skip the gym completely.

B; your testosterone levels will drop through the floor, your dick will stop working and quite possibly you will end up on TRT for the rest of your life.

C; you will waste away to Nazi POW levels of walking dead man, 1400 cals is barely enough for a human to survive on.

You fancy that?

[garethlewis]

Sorry you'll have to excuse my ignorance

If I am 350lbs and looking to lose weight, I would need to consume a daily limit of 280 grams of protein (350x0.8) in order to do so without muscle loss? I eat about 5 meals a day so that's about 50 grams per meal instead of my usual 30 grams

I am still confused as to how many grams of carbs I should be eating to achieve my goal
