A) Situations definition: Maintenance is eating according to energy balance, no positive energy balance, no net fat gain, largely true.
B) Your definition (I think): Maintenance is eating according to maintaining bodyweight. If a major stimulus is changed (ie. you move to the moon, a bodybuilder stops training, hormonal changes), then eating a bodyweight maintenance will result in a gain of fat tissue as muscle is lost. Also true.
uhhhhhhhh...... if you are maintaining according to energy balance, then you are also maintaining your bodyweight... our definitions are identical
only exception: maintaining calories doesn't mean you're maintaining water weight, so if you exclude water weight (which fluctuates daily) from the equation then they are the same.

The important point I am trying to convey to you is the reason the two definitions are often interchanged (ie energy balance == weight maintenance) is because for 99% of people on 99% of diets they are essentially the same thing. Unless you have extremely low bodyfat and extremely large amount of muscle or have drastic change in lifestyle (ie get wheelchair bound or move to the moon, or hormones involved) worry about losing appreciable amounts of muscle tissue is not necessary. Most people on this msg board are not in danger of losing enough muscle to effect energy expenditure if they stop training.
People often think they have experienced muscle loss for two reasons, both are wrong:
You may lose A LOT of strength but it's not because of losing muscle tissue. That's why it will take 5 years for someone to build their squat from 225 to 405 but only 8 months to train it back from 225 to 405 after they take a few years off.
You main gain a lot of fat when you stop lifting and keep eating the same. But it's not because your energy balance is changed due to lost muscle but rather due to the fact that instead of using energy training you are probably watching TV.
IMHO those most important takeaways to take from this discussion. It's largely thought and stated in broscience that you lose muscle tissue which effects metabolism and causes you to gain fat. While this is possible, it's not what happens to most young men who stop training, especially not in the short term.
There's a lot to ingest there, but basically:
We agree that if two atheletes:
- Both have the same caloric balance
- Both consume and burn the same amount of calories
- Both maintain the same bodyweight
- Only one continues to lift weights, while the other stops
The one that stops lifting weights will, eventually, lose more muscle than the one that continues to lift weights. The amount may very from half pound over the course of a year to 5 pounds in one year, but it will not be zero.
And, in fact, if the athlete that continues lifting is noob enough, he will actually gain muscle over the coruse of a year.
Nobody can deny the above.
