Whenever you go grocery shopping, its inevitable that you will find food products advertising being ”LOW FAT”. Companies often advertise their products in this way because it is a common conception that eating fat makes you fat. By doing this, they are able to attract consumers that are trying to lose weight. However, is it actually true that dietary fat is ”unhealthy” and should be avoided for weight loss?
CSA astronaut and ISS commander Chris Hadfield demonstrates how it is astronauts lift in space. But he notes they’re not all trying to get stronger–lifting weights is more of a counter measure to make sure astronauts don’t atrophy away in reduced gravity.
As you can see in the vid, they hit plenty of exercises: deadlifts, squats, and good ol’ jogging on the treadmill. Except their equipment looks a lot more expensive.
In case you’ve missed my last few post, I’ve been looking into some of the physiological effects (besides intended ones eg weight loss) of intermittent fasting (IF) and caloric reduction. I was incredulous when I heard IF increases net growth hormone (GH) secretion, so I decided to investigate.
Intermittent fasting sounds like an attractive dieting scheme. A quick visit to bodybuilding forums reveals no shortage of people who will attest to its effectiveness. Yet as someone well versed in human physiology, I am suspicious of what less noticeable effects it may have on the human body. For one, the brain runs entirely on glucose and absorbs it via facilitated diffusion, so low blood glucose means low fuel for the brain. I decided to investigate further.
Let’s take a little break from hypotheses and conclusions to take a look into how drugs are discovered. I’ve had the pleasure of meeting Dr. Harish C. Joshi at Emory University (Atlanta, GA) who discovered a promising drug for chemo-prevention.
I’m sure we’ve all ran into these terms at some point and possibly seek out low-GI foods at the supermarket without really knowing why. I mean, what possible reason could I have for buying 2% yogurt over fat-free yogurt? Turns out, GI is key.
Spoiling food sucks. Finding food that expired a day or two ago is pretty close. Sometimes when whatever food product I’ve missed the expiration date by is expensive/tasty/I’m-craving-for, I’ll disregard the labeled date and eat it on the spot. I had some Trader Joe’s honey Greek yogurt that met this fate a few days ago. Since I usually feel fine, this habit of mine lives on.
Part of the feedback system for appetite include volume sensory neurons lining the stomach. Such receptors are activated by higher stomach occupancy and signal the brain to feel less hunger. WiseGeek put together a nice visual indicator of how calorie-dense some common food items are. By eating less calorie-rich foods, you can activate volume sensing receptors more quickly to feel less hungry after eating fewer calories. Here are some examples:
As someone employed in medical research, I’m a little bothered when my friends self-diagnose using webMD or self-medicate rather than consult physicians. I think those of us trained in health-related fields are especially prone to this; when I get sick, I probably think I’m smart enough to know what’s going on. We can debate whether this is because I’m cocky or because I’m subconsciously protecting myself by pretending to have control over sickness, but clearly running a fever means more computer screens lighting up and fewer doctors’ appointments.
