The real reason Lochte sucked:
Seriously, I'm not the guy who tells you how you have to eat in order to lose weight, optimize performance, etc. I'm the guy who tells you how you DON'T have to eat in order to ...
Obviously, you don't have to 'eat clean' to lose weight. And I think it's just as obvious that you don't have to 'eat clean' to win Gold Medals, world boxing titles, etc.
Now, there may be a biological basis for feeling better after 'eating clean' vs. other approaches. On the other hand, placebo effect is quite powerful. After all, we've been bombarded with admonitions to 'eat clean', lest we feel lousy. So, from that standpoint, not wonder we feel lousy when we don't!
To satiety, hunger pangs, etc., I don't begrudge people from eating in ways to effect the former and stave off the latter. But I do not believe it is necessary to deprive one's self of foods typically classified as 'junk.' Basically, I think it's fine and dandy to feel hungry now and again.
Note: I put 'eating clean' in quotes because (A) nobody seems to agree on what it constitutes and (B) I consider it a bit of a scam anyway.
But let me also stress that whereas I rise to challenge the food police, by the same token, I don't argue (at least very long) with people's strong eating preferences. Indeed, my latest client is a 'Certified Holistic Health Counselor.' So, I know shes going to eat her organic produce, pea protein and the eight different supplements she's taking. I do choose my battles carefully.
