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.

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.

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.

comment How to improve half marathon pace?
This is similar to the plan I always use. I used to skip out on the track runs sometimes, but being diligent about them shaved 10 minutes off my race time. My overall strategy is to build for 2-3 weeks, then take it a little easier for one week to let the benefits set in. For the track runs, I'd cycle through 400m's one week, 800m's the next, then 1600m's (precede these with a 20 min warm-up). My fast runs started at 3 miles and I worked up to 8 miles. My training peaks 2 weeks before the race (4 * 1600m, 8 mile fast, 12 mile long), and I taper off until the event.

comment What are the nutritional benefits of saturated fats?
-1 No, this is misleading. According to current research, saturated fat is -nonessential- in the diet. The USDA doesn't even suggest a minimum requirement for it. I'm pretty sure it can be manufactured by the body. Saturated fats do not directly clog your arteries, but bad cholesterol is manufactured from excess saturated fat, and that -does- clog your arteries. Yes, some unsaturated fats can become oxidized if you store/cook them wrong, which is bad, but there is a wealth of evidence that even so polyunsaturated fats help prevent the top 3 causes of death in the USA.

comment Can overtraining also occur during cardio exercise?
When I do cardio every day, I find my glycogen stores get depleted. After a few days of cardio, I start feeling like I was hit by a truck. If I take some days off and let carbs accumulate in my body, I can train way harder on the days I do cardio. That said, my typical cardio session can be 2 hours or more, so this may not apply to the average exerciser.

comment Why is it so hard to restart running if you stop?
Good question! In my experience, this happens for some people but not for others. A few years ago, I used to run an 8km race every year with my boyfriend at the time. It was most comfortable for him to alternate walking and running, but that killed me. I have to keep going--once I stop I lose my momentum. I don't really know why.

comment Should I train all muscles or concentrate on some muscles in each session?
Okay, okay, the sourcing was sloppy. I have revised my answer to include more complete and reputable sources. Most of my knowledge about practical fitness stuff comes from physical textbooks, so credible online sources are not my forte :/

comment Why do my legs hurt while jumping rope?
I'm skeptical about the advice to jump barefoot. I used to teach aquatic fitness barefoot, and developed some wicked pain around that plantar aponeurosis area. To prevent it I had to start wearing running shoes while teaching.
