But that is exactly what I am saying. I am not ignoring stored energy. With exercise increasing the amount of energy required, the body either requires more food (allowing you to eat more and maintain weight) or it has to use stored energy if you eat the same, resulting in weight loss. I think this is exactly what I said. Regardless, exercise must be accounted for.So, your example ignores stored energy already in the body. Technically, I can eat nothing for a day and my body will still "find" the calories it needs. This can go on for several days, as you probably know. Fat and muscle will br broken down for energy in the absence of "enough" calories from food. That's how weight loss happens, after all.
The other thing you are doing is thinking about calorie burn as a math equation when it's more like a budget. The body doesn't burn an equal number of calories per hour over a 24 hour period. Quite the opposite. If someone runs or walks 5 miles, the body provides that energy at that time. LATER, when you are resting, your body shifts and now instead of burning 80 cal/hour, it knocks that down to 50 cal/hour. Your body will adapt and use more energy when more energy is required and less energy for both essential and non essential processes when you are at rest. This is why "calories in/calories out" does NOT work.
If one wants to lose weight, what needs to happen is you need to feed your body just SLIGHTLY less than it needs to maintain its weight, but not so little that stress hormones get activated to hang onto your fat stores out of fear of starvation. You want your body tapping into your fat stores just a little bit every day. It's a delicate balance.
A balanced budget is a math equation. I am talking about an average daily intake vs expenditure. I clearly said that your body will adjust somewhat, for example when at rest. However, your body can only adjust so much and my example stands. A 400+ increased energy need will not be easily and completely compensated for by your body- thus either extra food is allowed to cover the balance or, like you said, stored energy is needed.
I am not saying that Calories in vs out is the only thing to consider, but to say that exercise does not allow a body to eat more and maintain weight is just not right either.
