Intermittent Fasting: Week 6

This week was pretty crazy food-wise. Not really sure why, just ate different sorts of things and had days that were WAY off goal, either over or under, in protein and carbs and calories. Still, on average it doesn't look much different from past weeks, which is good.

What went in (avg. daily):

Calories: 2,381
Fat: 140g (52%)
Carbs: 89g + 25g fiber (17%)
Protein: 178g (30%)

Fasting days: 4/7 (avg. length: 16.6 hours)

Weight: 175 (-1 lbs, 13lbs total)
Waist: 32.25 (-0.125", 1.75" total)
Bodyfat: 12% (-0%, 3% total)
Percentage to goal: 88%

Ab muscles are a little more visible now, but not yet enough that I would call it a six-pack. Funny that once I gave up on the vanity goal (the six-pack) and turned my focus to fitness goals, I'm finally starting to get one. Maybe a six-pack is like love: it only comes when you aren't looking for it.

My ankle is at about 85% and my shoulder is feeling pretty good, so I think the active recovery week worked. I might try running again today, to see how it feels.

I'm really starting to itch to turn this around again. I want to start 5x5's of weighted pullups and dips to help progress towards a muscle-up, which is my primary goal at this point. If I can keep this rate up without backsliding, I'll be at my goal in two weeks and I can start eating to support real muscle growth again - hopefully a slow LBM-only bulk, this time, so I can get off this rollercoaster.

Interesting observation: since I drastically lowered my carbs to focus on fat and protein, I've noticed that I'm NEVER cold. Indeed, I've taken to sleeping with the window open every night and my legs outside the covers just to keep from overheating in my sleep. Sweaters and sweatshirts frequently get uncomfortable. So for some reason my thermogenesis has really kicked up. A little googling turned up this gem on an extremely crappy and probably highly disreputable supplement site:

Among the nutritional activators, the various macronutrients have different effects on the thermogenic response. When you ingest food, your metabolic rate increases above the fasting level. In the case of protein, energy to process the protein, which is then used for tissue growth and repair. On the other hand, carbohydrates and fat function primarily as fuel and are used more efficiently as such by the body. Carbohydrates and fat therefore have a much lower thermogenic effect than protein.

So I would guess this is my body taking all that protein and converting it to glycogen, since I'm not giving it enough glucose, and the heat is a byproduct of that conversion. I don't know whether this means anything (good or bad), but it's interesting to note.

Oh no, poor Bekka. Is she buried under several feet of blankets, during all of this sleeping with the window open insanity?

I have my toaster of a husband keeping me warm ... in fact - lately, i've often been forced to kick the comfortor off entirely and sleep with just the sheet. (and I am usually quite chilly) I am thankful for the open window.

SO interesting... I have historically always been cold, even when everyone else is sweating. This year is different - I'm wearing short sleeves to work, and sleeping with all the windows open (even though it's getting cold). I never even thought about connecting that to my diet... but it does make sense. Cool observation, Daniel.
