Carbs yes for muscle growth

I'm pretty sure carbs are just for energy. Protein for muscle

Carbs are needed for muscle growth and repair. It's called muscle sparing. When you exercise, glycogen (provided by carbs) is burned first for energy - without adequate glycogen, your body will resort to breaking down actual muscle. Downing massive amounts of protein won't compensate for that actual muscle loss.

Low carb is great for losing weight, but that weight will also include substantial amounts of muscle. To actually efficiently build muscle you'll need plenty of carbs both before and after working out.

Negative. Carbs are not essential. Muscle glycogen is needed for energy and can be formed via breaking down protein. These proteins can come from an exogenous source (protein shake) and don't have to come from breaking down muscle. You're right in saying that protein from muscle is broken down when glycogen stores are empty, but glycogen can be made from exogenous protein via a process known as glyconeogenesis.

As for low carb and weight loss, it's a great way to stay in a calorie deficit, but not essential for weight loss. Calories in vs calories out rules above everything regardless of your diet 😎

  • Carbs are important for serotonin production. In case anyone didn't know. Can google

Lots of optional things are important for seratonin. Not obligatory.

I was a zero carb power lifter for about 4 years before adding carbs back in. I had no issues. My SO runs cross country and was on the same diet as I was. No issues and regularly pushed PBs. Putting on muscle was even easier for me than a carb heavy diet. Higher energy levels too.

There are different ways to meet your chemical and nutritional needs that do not necessitate carbs. They aren't bad when consumed intelligently from healthy sources but they aren't required. Saying carbs are required is misleading.

Yep, and you'll have much better results building muscle with adequate carbs.

Calories in calories out - well no kidding, who said otherwise!

Maybe not essential but carbs make the process easier. There is a reason big body builders eat shit tons of eggs (protein) and pasta (easy carbs).

Proteins take roughly 20-30% of the calorie input to digest, carbs are closer to 5-10% and fats are 0-3% to digest.

And atop that, you are tangling up more energy and resources to trigger the glyconeogensis process, so you are at even lower efficiency.

Low carb, low fat diets work incredibly well because of that. Aside from protein being hard to digest, you also expend energy to turn it into glycogen.

Good for weight loss, awful for muscles.

Here's a recent study showing no significant difference in high carb vs low carb for weight loss and body composition. In the study they note that the high carb group lost significant amounts of body mas, aswell as the low carb group. No significant differences were found when comparing the low carb group to high carb.

The deciding factor for weight loss?

Caloric deficit.

Weisenkrone t1_irih2zn wrote

Your calorie intake is the amount of calories you consumed, subtracted by the calories needed to digest that.

That's what I'm trying to say.

At the end of it, yes it boils down to the caloric deficit - but the caloric deficit is the result, it's not the process.

If these two groups had the same calorie intake, then the study went off effective calories not the numbers on the label of whatever you ate.

Additionally, when people reduce carbs usually they just increase fat which digests even easier then carbs.

huey231 t1_irii249 wrote

Sorry I misread what you were trying to say. Yes you're 100% right regarding the thermic effect of food on your overall caloric intake!

Weisenkrone t1_irij27h wrote

Not just thermic effect, glyconeogensis is also is a notable impact.

Carbohydrates can be directly digested directly into glucose, if you do not have enough carbohydrates in your diet, your body can synthesize it.

We're not talking a massive expense, but it's still there.

I like your part about not needing carbs for muscle growth because I am currently doing keto, have lost weight and feeling great! I’m also working out to build muscle and eating ample amounts of protein daily. What I don’t like is your “calories in vs calories out” argument. I tried that in the past which also included consuming carbs at the time and I lost very little weight very slowly. Keto has taken my fat loss to a whole new level, which I’m usually eating less than 20 carbs a day.

A high fat diet impacts satiety greatly, meaning u feel less hungry (i.e., fuller) more often. This means u ultimately eat less... so calories in vs calories out is still the deciding factor

Yeah, not sure how he can try to argue against the calorie deficit theory. Unless he is stating that his body magically produces extra calories

Conservation of mass/energy is somehow tough for some people. It's like they aren't rooted in reality. Granted, I was a high school wrestler so understanding weight / metabolism is second nature.

TheBertinator3000 t1_ira962c wrote

There's something else, often overlooked when talking about keto.

Being a highly restrictive diet, keto also forces you to cut out most of the highly processed junk food (if you're doing it at all correctly). A low junk food diet is great for improving satiety, regardless of your fat/carb balance.

Not really… I eat about 2500 calories daily on keto

Well it sounds smart for sure. And I don't know enough about science to dispute you

NeedleworkerHairy607 t1_ir9l5e0 wrote

It's not true. If it was, then people on keto diets would just shrink and waste away to nothing, and they don't. They can build muscle just fine.

Anyone who speaks about fitness in absolutes like that, doesn't know what they are talking about.

NeedleworkerHairy607 t1_ir9kr7q wrote

If this was true then people on keto diets could not build muscle and are constantly losing it, and this is obviously not the case.

1

molotov_billy t1_iracfqw wrote

Not true, it isn’t binary, but they would build muscle faster without keto.

NeedleworkerHairy607 t1_iranry0 wrote

So... That directly conflicts with your last post where you said you need to eat carbs or else "you will lose substantial amounts of muscle."

molotov_billy t1_iraqb1y wrote

If you're losing weight, ie a calorie deficit. Keto is great for losing weight, not necessarily for building muscle. If your primary goal is to build muscle then carbs are an important part of your diet.

I put sugar (lemonade) in my yoghurt to indeed get some carbs in after a workout, sugar are "carbs" right?

The body doesn't jump straight from carbs to breaking down your muscles. There's also fat, and ketosis is kind of central to the keto diet.

As far as I can tell, the jury's still out on exactly the effects of prolonged ketosis on muscle gain and loss. Although I will agree with you that if you're in shape and your goal is to build muscle, you will definitely want carbs in your diet. But I think your claim that low carb diets always lead to notable muscle loss is disputed by some studies.

Here's a pretty decent article summarizing what we know about the relationship: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6724590/

But this topic is concerned more with exercise for the purpose of mood regulation/energy levels, and different people may prefer different "secondary benefits" such as losing weight or gaining muscle mass.

Look at what those massive body builders eat. Protein is important yes, but they also load up with shit tons of carbs.
