I guess mine is about diet....
There are no magic formula's, no ratio's of carbs/protein, no secret oils or foods that reduce hunger or stimulate metabolism. Sure, there's caffiene and other things....but in the grand scheme of things I've found and realized that we are far more slaves to our bodies then we realize and by this mechanism our weight is somewhat dictated by our own internal balance.
We like to think we're in control and have free-will and make our own decisions....but in reality we just get a fraction of our lives to do with what we want. Indeed: every day we are forced to sleep, eat, urinate, deficate and tend to our bodies needs. If the body senese we're low on fluids, we get thirsty. If we need calories, we're driven with hunger. Even the procreation of the species is ensured with hormonal drive...think about it; what if there was no orgasm or any of those hormones...would you really drive in your car, find a motel and pay for sex?
But seriously...our bodies probably maintain an average intake of calories on a consistent basis that we're not aware of....it knows the balance of things. I've stuffed vegetables, water and other no or low calorie foods into my stomach until I can feel my gut bulging...and yet, my low blood sugar and the body getting little or nothing in the way of glucose-rich nutrient still drives me to want to eat more.
For me, I've found I can do a LOT of cardio and weights....but the body knows when it's lost calories and it fully inspires and drives me to replace each and every one of those calories. The body has a scale, a balance and a system...it's inescapable and undeniable: to lose weight, you must endure a calorie deficit and YOU MUST ENDURE HUNGER. Hunger means the equation is upside-down and you're in deficit....and deficit is what is required to lose weight.
So my thought is that you have to keep this in mind and realize it's a battle of mind over body. The chief thought is that once you lose that weight and reset the internal thermostat, the body will reset to that weight and then you can go on maintenance to maintain that state.
I hope this was helpful...it's hard to put to words these thoughts properly.
On another topic/question: I'm under the impression that in order to make progress with weight-training we really need to push ourselves SUPER-HARD. That means doing reps until failure and really enduring some serious pain towards those last couple reps. Some people suggest you don't need to go balls-out to the extreme...but I'm thinking that's when you tear the muscle and induce rebuilding larger/stronger. So on a scale of 1-10, do we need to pound a solid 10+ to make progress...or can moderate levels also achieve results?
