You Know When You're in the MFP "Zone" When...
...you start weighing the water going into your post-run smoothie.

Beef Runoff - Fat vs Water Content
So I put a beef steak or cubed beef or etc in a pan, and cook it. Lots of liquid comes off. If I drain that liquid off and weigh it, approximately what percentage of the weight is fat versus water? Obviously there are tons of assumptions here - for example, the longer it simmers, the more water evaporates. I'm just looking…

Completely freaked myself out
I've committed to a 70.3 Ironman next June. Right now, I'm fine with Sprint distance, and would get through an Oly distance within the time limit. I laid out the nutrition map and did the burn numbers and blah blah blah at my expected race weight for a 5:30h finish time (70th percentile). And now I'm struggling to talk…

More Evidence that Exercise Directly impacts Weight Loss
Looks like they really, truly found it - "irisin". Levels elevate with cardio exercise. This is important because irisin controls the creation of brown fat from normal white adipose fat. And that is important because brown fat is fat that actually burns other fat. cell.com/cell-metabolism/abstract/S1550-4131(15)00392-7…

Water from glycogen depletion
Where does the water released from glycogen usage go? Do we sweat it out, does it go to the bladder, or does it get used as a catalyst in other reactions and we eventually breath it out as CO2? It doesn't really matter, I'm just curious about the biochemistry.

Protein Leverage and Exercise
I was thinking about this...a number of us here have self-reported about how much easier it is for us to succeed at weight management when we have fairly vigorous exercise habits. I'm wondering if it might relate to the "protein leverage" hypothesis. Let me 'splain... The protein leverage hypothesis suggests protein…

Exercise & Weight Loss Correlation
I'm a data junkie. Always have been. Not apologizing for it. :smile: For reasons I don't even remember anymore, I was pulling all my Strava logs for the past 2.5 years into a database. And an immediate, obvious correlation popped out. Like, like a giant meteor crossing the sky. Every good month of weight loss - every.…

Training for your body type
As a tall, broad shouldered body type, I've always found it interesting how there were sports that I could just never excel at, no matter how hard I trained. The same would be true for a different set of sports, of course, if I was shorter and slighter. Below is a graph showing the relationship between body weight and…

Question about protein consumption
Assuming you're moderately active and eating somewhere around 0.8g/pound of LBM - ie, "a lot" by normal standards but not at a big excess - how much of that protein is used for fuelling body functions and how much is used for repair/maintenance of lean body mass? My understanding is that virtually all of it is used for…

Calories per step
So I decided to calibrate myself. All numbers approximate. Distance: 13km Steps: 16,000 Net Calorie Burn: ~525 -> 16,000/525 -> 30 steps/calorie, or 0.033 calories/step Validating this the other way.... 30 steps -> 24m, 1 mile -> 1850 steps/mile -> ~60 calories/mile Close enough. This was hiking with a heavy, heavy pack.…
