I don't really understand what you mean by "reject". If you are refering to constructivly using the cals, it all depends on your lifestyle, training intensity, and how your cals are broken down. Excess cals are used for different things. Example: Carbs are are converted to energy through glycogen. What glycogen that isn't used is stored as fat and converted to urea as well. The bioorganic chem behind it is rather complex as just carbs alone are converted into about 10 different compounds, let alone fats & proteins.

My largest meal of the day is about 650-800 calories... and I don't have any problem with gaining fat.

I think that 500 cals may be a little low. I also take in between 600-800 for my largest meal and have minimal fat gain. Also Geoff, where in Buffalo do you live, im from west Seneca

It is totally irrelevant how much you eat at any one time -- caloric deficit/surplus over a 24 hour (or longer) period is all that matters.

If you eat 800 calories in one sitting, obviously some is going to be stored (unless you're huge) as fat; otherwise, you'd have blood glucose levels off the charts, etc. etc. However, if you stay under/at your maintenance calories for the day, you will have periods of time when you're drawing on those adipose stores for energy, so the net fat balance will be negative/0.

The only real exception would be in the case of refeeds with carb depletion.

Bump - definately the overall cals for the day is what matters most IMO. I may eat one meal that reaches 800 cals, but I only have 300-400 calorie meals for the other four meals in the day.

so if someone eats 1,500 cals i one sitting, but stays under their maintenace level for the day, of say 2,000 cals, it wont have any affect on their physique?

their metabolism will be shot.

yup...there is a big difference between having 1 - 1500 calorie meal compared to 4 - 400 calorie meals and 1 - 800 calorie meal. even though there is one large meal in there, the body still gets food from the time it wakes up to the time it goes to sleep.

right their metablolism would be shot, but what if they only did that for 1 day, as in eating 1500 calories, then the next day started back to the regular 6 small meals a day?

The reality would depend on a lot of things. Ultimately, unless they repeated that constantly, they probably would see the same results as they would eating the 1500 calories over the course of 3-6 meals.

Honestly, meal frequency IS overrated, but eating fewer than 3 meals per day opens the door for metabolic slowdown (though this would arguably be negated by the metabolism-enhancing effects of the single meal) but more importantly, would virtually guarantee catabolism to a significant degree.
