Calorie deficit = no muscle mass gain. so why am I stronger?

Hexahedra

You can gain muscle while on a deficit, because if you do progressive strength training you invariably introduce micro tears in your muscle, which your body considers as high priority for repair. However, your body is a very complex system that always tries to optimally balance competing needs, especially in a deficit. It will repair your muscle, but it's not going to spend too much energy reinforcing it.

When in deficit your body will eat both fat and muscle, that's a fact. When you exercise hard and forces your body to repair muscle, it counteracts this catabolic effect. That's why people exercise during a deficit.

Now, if you want your body to really build muscle without holding back, you need to eat at a caloric surplus.

In short: gaining muscle during a deficit is possible, but it's not gonna be anywhere near the rate of gain during a surplus. Think of the gain during a deficit as a bonus. There is a reason why professional bodybuilders choose to do the bulk & cut cycle; they can gain much faster during the bulk phase.

Interesting. I've always read 3-8%. Hopefully we can agree that this margin of error is defined as actual vs calculated, and the variance I was referring to is net change.

I am 1.5 weeks into a cutting phase (Granted I'm taking a fat burner and am supplementing with BCAAs for the first time ever). I am tracking everything.

Beginning - 178 lbs, 13.1% BF.
This morning - 177lbs, 12.4% BF.

These numbers are from calipers, read by the same person, at the same time of day.
Doing the math, that is 1.4 lbs of fat loss and .4 lb of lean mass gain. Even taking any kind of variance into account, there was some muscle gain.

Variance is between +/- 5% to10%. I'd say that's a pretty significant variance if you're talking about adding muscle on a calorie deficit.

You can strengthen your central nervous system so that it recruits more muscle fibers during a lift. This is essentially what Olympic power lifters do.

I like this articles explaination of some research done on the sbuject.

http://muscleevo.net/calorie-deficit/

Essentially, it depends on the persons conditioning and status.

In summary, some people can and do build a decent amount of muscle while they’re in a calorie deficit.

But it’s a phenomenon that’s generally limited to people who are very overweight and have never lifted weights before, or those who are returning to exercise after a layoff, where muscle memory comes into play.

Once you’ve move past the “overweight beginner” stage, building a significant amount of muscle while losing fat is a goal that becomes progressively more difficult and will normally require some kind of calorie cycling strategy if you want to see decent results.

Interesting article but it only refers to men.
Can the same deductions be made for women knowing that we have a different fat:muscle ratio than men?

All that muscle weighs more than fat nonsense you see, in reality both weigh about what water weighs. A pound of muscle is about the size of a pint. It doesn't take a whole lot to be a pretty obvious difference.

If that were true, then the water displacement method of measuring body fat percentage wouldn't work, because it is based on body fat having a lower mass per unit of volume than lean body mass does.

ahhhhhhh

::face desk::

a pound is a pound is a pound


weight, volume, and density are NOT synonyms... FFS

Human body fat has a lower specific gravity than muscle does, which means that it is less dense, which means that it weighs less per unit of volume, which means that pound of fat takes up more space than a pound of muscle.

0.90 g/ml for fat
1.06 g/ml for muscle
1.00 g/ml for water

Yes, muscle is more dense than fat or water. Sensitive equipment can pick up this difference. To the naked eye, both take up about as much space as water.

Gain 5 lbs of muscle and chances are each of your thighs will be 1" bigger, your chest will be1.5" bigger, and each of your arms will be about 0.5" bigger. It is a plainly obvious difference. Small bit of muscle gain and you're a lifetime member of the "skinny jeans ain't happening" club.

Sounds like a good excuse to go into a calorie surplus to me! TIME TO GET BIG! No more of this losing lbs. ticker!

Generally speaking, women can expect about half the results of men as far as muscle mass gain (read the article by Lyle McDonald which I linked to earlier in the thread). A male relatively new to training, given optimal diet and training (which is a rarity in itself) can put on about 0.5 lb. of muscle per week; a woman can expect the results to be around 0.5 lb. every two weeks. This is due largely to the fact that women possess/produce somewhere around 10-15% of the testosterone that men do.

Bottom line. Get a body fat test now and after. Compare results. Only way to know

That was based on this study.

I don't profess to be an expert but I have read a lot about the topics mentioned here. Some people I have read believe that increased strength (notice I said strength, not muscle) gains are a function of both neurological adaptations AND muscle gains. What the percentage of neurological adaptation and muscle gain is will vary. If you are not gaining significant muscle weight but are getting stronger, then these experts would speculate that you are mentally getting better at being stronger, i.e., neurological adaptation.

Strength is a skill like driving, typing, swimming, doing karate or whatever. The more you practice at doing deadlifts, head stands, pullups, pushups, whatever, your body will get mentally better at doing them and may also add muscle. I would not discount the ability of your body to get stronger by neurological adaptation. In my own experience, I have seen signiticant strength gains from practicing moves and greasing the groove (very frequent practice but never to the point of exhaustion) on certain exercises although I have certainly not gained any significant muscle.

Get a body fat test done. End the debate

Wow. While I admit that this rained on my parade a bit (okay maybe a lot), it does make a lot of sense. I too thought that I was gaining muscle since my lifts were all going up, and my muscles looked larger, even though I am in a mild deficit. I guess that I overestimated the noob gains. I figured that the "pump" effect leveled out after a couple of weeks, and so the additional size was extra muscle. I think that I am just dropping body fat and gaining definition instead.

I REALLY appreciate all of the good info in here without name calling, arguing, or misinformation (as far as I can tell). I only read the first two pages, but they were the best two pages I've seen on the main forum in a while :flowerforyou:

One question is left in my mind:
If you can gain strength without gaining muscle, can you gain strength while LOSING muscle? In the extreme case of an extremely obese person, I think the answer would be yes, but what about a "normal" weight person?

Bump again because of lots of good info in here.

Novices can get a bit of muscle gains on a deficit, though the strength increases come from taxing your central nervous system. When you recover, from my understanding, your central nervous system is able to more readily recruit motor units and increase the synchronization of the nerves firing. Or something like that.

Source: http://www.ncbi.nlm.nih.gov/pubmed/3057313

This agrees with what I've been reading through translations of Soviet physicians that supported their Olympic team. They talk about gains of 35% in primary lifts coming from the development of neuromuscular coordination. In other words, your body learns to recruit more muscle motor units and coordinate them to fire at the same time.
