Apr 1	comment	What are the nutritional benefits of saturated fats? @Allen Here are three academic studies that contradict your conclusion about polyunsaturated fat being more dangerous that saturated fat. PubMed1, PubMed2, The American Journal of Clinical Nurtition. Considering CVD is the number one killer in the world (Wikipedia), I wouldn't advise people to cut out polyunsaturates.
Apr 1	comment	Is it true that thinking uses a lot of calories? I've modified the answer to reflect the nature of that pubmed citation better. For me the SciAm article isn't evidence against the quote from Livestrong because it takes firing neurons to operate body processes as well as thought. The article doesn't distinguish between neurons dedicated to different tasks. The last paragraph does indicate that visual stimulation may increase energy expenditure, but is it by enough to be considered "a lot"? And is visual perception really considered "thinking"?

Mar 31	comment	Is it true that thinking uses a lot of calories? The brain probably consumes some of that extra energy some of that extra energy (I really don't know for sure). But a stress response is systemic, causing stuff like increased heart rate and breathing rate, which consume quite a bit of extra energy. You're right though, there are boundary issues; even if the brain doesn't burn much extra energy itself, it triggers the stress response, so you could say it's responsible for burning those calories.

Mar 30	comment	Should I eat more calories when working out even though I'm trying to lose weight? Very detailed answer. The definition of BMR is off though. I think for the most part you just mean energy expenditure, which is the sum of BMR, thermic effect of food, and physical activity level (PAL). BMR only refers to the very base level of energy expended at rest. Aerobic exercise does cause a short-term increase in BMR and, as you mentioned, strength training causes a long-term increase in BMR, but when you're talking about burning calories during exercise, you're usually talking about PAL, not BMR.

Mar 30	comment	Quinoa: red or white, which is healthier? That was the first place I looked too. I assumed "quinoa" referred to white quinoa. Maybe red quinoa is too esoteric. NutritionData doesn't have orange bell peppers either.

Mar 29	comment	What are the nutritional benefits of saturated fats? @Greg The USDA DRI table references this report done by a third-party organization. Since it's numbers based and not as subjective as something like the food pyramid, I consider their recommendations credible. Unless you are not eating enough energy, saturated fat's role in cell membranes is irrelevant because the body can make saturated fats from unsaturated fats, carbs, protein, and even alcohol.
