Well said Ben.
The problem is people think that using supps will magically give them more with the same amount of effort. Nutrition is key to training, however, good training and rest is also vital.
You can boost your thermogenic reactions naturally, furthermore doing exercise developing LBM will naturally increase your thermogenic capacity. For example, I'm literally a walking hot water bottle owing to my lifestyle! A lot of "fat burning" stacks are not recommended - they're based on a naughtier version, which basically make your heart beat faster and make you more wired, i.e. more fidgety and basically moving more and as such using more calories. Why do that artificially, just do a bit more in the gym, or go for a morning walk, vary your diet, change your training.
People use supps without really knowing how they bind with different molecules in your body, how they affect you, and jump in feet first without really understanding the science behind it.
Then again maybe I'm different, even aspiring or other painkillers, I don't take those really unless I really can;t cope, and even then I've researched and learnt about how they work with my body. I don't like putting things in my body that I don't understand.
Don't get me wrong, when doing intensive training like AGVT for example, I do supplement to help me recover and give me maybe a slight overdose of some nutrients owing to the punishment my body is receiving. However I dose it myself, I've tested it on my performance - sure it's a bit contradictionary and hypocritical saying that I don't like putting things into my body without knowing what they do, but I make a well educated decision.
Diet and nutrition are key to any training - everybody is different though so you need to work out what your body responds better to, however the diet and nutrition importance doesn't change.
Americans love their supps because it's a huge market over there, there are so many there that are jus filled with filler and do nothing, because people will believe it. Susceptability and positive mental attitude will often make you believe that it is "working". Don't get me wrong there are many supps that work, I'm a big fan of natural herbal supps - but taken from time to time and in measured quantities/amounts. The yanks have been brainwashed into thinking they NEED these supps - you don't. Certainly in the sunny states where you get lots of sunshine, fresh fruit and veg you're living in an ideal environment for good health. Just add some fish and good carbs, some decent exercise and you're on your way to a perfect lifestyle.
The Mediterranean lifestyle to me, is still the "perfect" mixture of what is needed for your body. Good fats, fish, 8-10 portions of fruit and veg a day, lean meats, sunshine, exercise, red wine - perfect! There's a lot of evidence (some anecdotal to be fair) that the Med lifestyle is extremely good, and helps lower risks of diabetes, an heart conditons. You don't see them supping themselves up to their eyeballs
