Maybe it wasn't clear then, but from what I understood, you were eating once a day to allow daily cheat meals in that single feeding a day. You just listed maccas, KFC, etc as your regular food intake. And like I said, it will work controlling appetite and weight. However I don't think you'll find anyone say that approach is ideal for gains.
I'm simply going off recent studies I've been researching where frequency is the key to gains. In both terms of training and eating. I agree that a constant drip feed of protein is not ideal either. The purpose of approx 30g of protein in a meal is that you need that amount after a period of no protein to elicit MPS. If you have a drip feed, you'll never achieve that either. But you're doing the other extreme; one massive peak and one massive valley. I think we can all agree that extremes are not the answer.
What number would you put on the worst possible eating approach vs the best? I simply gave a ballpark figure of 25%. It might not be that high, but there certainly is a significant number.
Frequency is the key??? Like I said are we in the 90s. Look up recent research most can't find significant differences between certain daily meal frequency.
Post some research. I'll be happy to have a read. Remember though 1 study doesn't prove anything. It's part of the puzzle, it needs to be repeatable.
I've been doing two meals a day for 5+ years. I'm doing one meal a day at the moment to allow for bigger dinners and see how it goes. I used to do 5-7 meals a day before that.
Like I said most are home cooked. I posted 1 fast food meal because I was on the road.
2 days ago I had a heap of chicken, 2.5kg of potato and sweet potato, sauces, some fruit and a small bowl ice cream. I have beef stroganoff with heaps of veggies ready for when I'm home. Most of my days I have a over 1.5kg of fruit and veg.
It's funny when I mention a fast food meal automatically all i eat is fast food. In any case I said it before. People think Macca's is magically bad. My burgers contained bread, beef, onions, lettuce, pickles and some sauce. No different to what people make at home or what people buy at some expensive fancy hippy organic place. There is nothing magically bad about it.
You are claiming one meal a day is the worst case scenario which it certainly isn't. It's not that long without food. After one big meal your body is digesting it for most of the day anyway.
