Sleep

My average response was Neutral to the following:

• I slept worse during the week.

My week was typical; there were no significant changes in my normal work, sleep or activity routine.

Overall Impressions:

I really enjoy this method of fasting.  It’s easy to follow and I felt no ill effects to the regimen.  I lost some weight, which was part of my goal, and felt healthy during the week.  I didn’t need to change my workout routines or the types of food I was eating.  I would recommend this method to anyone who wants to try IF, without having to make too many changes to diet and lifestyle.  Given all of the health benefits of IF (linked in previous posts), I would recommend Fast-5 to anyone looking to improve their health or to lose weight.

Next Week:

I’m taking this week off, as things are still very busy.  I’ll be fasting here and there, as that is just part of my lifestyle, now, but I won’t be formally following any specific program.  Next week (starting on July 4), I will begin the Eat Stop Eat program.  I’ll put up a post explaining that IF regimen soon.  If you are interested, check out Brad Pilon’s (creator of Eat Stop Eat) website.

6/20/11: Fast-5 Day 6

Weight – 154

6:30am blood glucose – 85mg/dL

Update:  I did not fast this weekend (on purpose).  I used the weekend as a “re-feed.”  I ate eggs and bacon/sausage for breakfast both days.  The rest of the day, I ate as I normally do, with the addition of a sweet or two (macaroons, dark chocolate, organic ice cream).  Even with the extra sweets and the extra daily meal, I only gained back one of the pounds I lost.  Not bad.  This morning, I woke up a bit hungry, but I pushed through it.  My energy levels are fine.  I did a short, intense workout this morning (resistance exercises on our school’s playground for 10 minutes – assisted pull-ups, squats and the plank), and walked for about 20 minutes.

6/17/11: Fast-5 Day 5

Weight – 153

8:30am blood glucose – 76mg/dL

Update:  I lost another pound, and I feel like I’m fitting into my clothes better, as well.  This morning has been the easiest so far, regarding hunger.  I decided to check my blood glucose later in the day and found it to be lower than my usual early morning levels.  I have not noticed any dip in energy levels today either.  I even went for a walk this morning, and felt great.  Tomorrow, I plan on not fasting.  It will be a “re-feeding day.”  As is a concern with calorie restriction, I don’t want my body to adjust too much to this caloric intake by slowing down my metabolic rate.  I’ll probably see a bit of a rebound in my weight, which is okay.  I’ll post a summary of the weekend on Monday.

6/16/11: Fast-5 Day 4

Weight – 154

6:00am blood glucose – 90mg/dL

Update:  Yet again, I’ve been experiencing hunger in the morning.  It’s not been too distracting, but definitely noticeable.  I’ve been doing IF for a while, but this is the most days in a row that I’ve fasted for extended periods of time.  I have lost a couple more pounds.  We’ll see if that continues.

TMI Warning – I’ve noticed that since starting this fasting regimen that my bowels have been moving faster and more regular.  Prior to this, I’d have movements once, maybe twice per day.  This week, it’s been more like 2-3 times per day.  Interesting.

I broke today’s fast a little early, as we were having a luncheon at work (Chipotle – yummy!).  My approach to my diet (and fasting) is to not be too stringent about it.  I am passionate about my way of eating, but not obsessive.  I run my life.  So, I wanted to have lunch with my work friends, and that’s what I did, at about 1pm (an hour before my fast should have been completed).  I forgot to take my blood glucose prior to the meal.  I’ll be sure to do so tomorrow.

6/15/11: Fast-5 Day 3

Weight – 156

6:30am blood glucose – 87 mg/dL

Morning Update: Again, I have been experiencing some hunger pangs this morning, but nothing that I can’t handle, or that doesn’t pass quickly.  I’ve been trying to drink water when I feel that sensation, which helps (and keeps my hydrated).  I dropped one pound from my starting weight, which is nice to see (no the be all and end all, though).  My “break-fast” today will be a raw tomato (with Himalayan salt), sausage with tomato sauce, 2 hard-boiled eggs and come cherries and strawberries.  Not sure about dinner tonight, as my mother is coming and said she wants to treat us.  It’s nice that I don’t have to be too careful eating out, as I know my calorie intake for today has been low (that said, I should mention that I rarely eat out, mostly because I have a hard time finding healthy foods at most restaurants – food just isn’t as rewarding or tasty when I know it is unhealthy).  One more observation, I love not having to spend time eating breakfast in the mornings, during the workweek.  It makes my mornings run smoothly and gives me time to prep for the evening’s meal.

1:30pm blood glucose – 84 mg/dL

6/14/11: Fast-5 Day 2

Weight – 157

6:30am blood glucose – 84 mg/dL

Morning Update:  I found it interesting that my weight stayed stable and my blood sugar went down a few points.  I’ll be closely monitoring my glucose levels, to make sure they don’t drop too much, as I continue fasting.  I have basically normal energy levels this morning.  I felt hungry when I first woke up, but that sensation passed quickly. 

1:45pm blood glucose – 69mg/dL

Afternoon Update:  I had no problem fasting this morning.  Very few hunger pangs.  My energy was a little low in the morning, but that’s probably normal for me.  Sometimes I need a little caffeine in the morning and I haven’t been having my morning tea.  The lull in energy faded and I went through the morning energized and focused.  The time went quickly, too, as I’m very busy at work at the moment.  The most surprising thing was that my blood glucose number dropped from 84 to 69.  I checked with the nurse (I work for a school) and she said that this was not a cause for concern.  I’ll continue to closely monitor this, though, just in case.  If we drop down to 60mg/dL, or lower, I may decide to alter what I’m doing.  For lunch today, I ate a salad (with bacon, cranberries, olive oil and apple cider vinegar), 2 hard boiled eggs, a slice of meatloaf (with organic ketchup), and leftover fruit (local cherries and strawberries) from yesterday’s lunch.

Fast-5 Briefly Explained

The Fast-5 protocol is quite simple.  You fast every day for 19 hours that leaves a 5-hour window within which you can eat.  Fast-5 does not specify any type of diet or eating program.  It centers mainly on meal timing.

The Fast-5 book does a good job describing the two major forms of hunger and how they relate to this style of eating.  Limbic hunger is related to overeating.  The limbic system is the primitive part of the brain, driving emotion and memory.  The book states that limbic hunger is the drive that ancient humans (hunter-gatherers) felt that drove them to eat as much as possible while food was available (to store as fat for times of scarcity).  Limbic hunger would have been a useful survival tool in times when food was more difficult to come by.  Now, however, that food is abundant, we need to watch out for limbic hunger.   When fasting, we are not engaging our limbic hunger system,

Instead, we feel somatic hunger.  The book defines this hunger as the “sensation of discomfort in the stomach that is commonly called hunger or hunger pangs” (page 21).  This sensation is the result of many, complicated hormonal interactions.  It can be unpleasant, but hardly debilitating (which doesn’t make evolutionary sense – if hunger knocked you out, you would surely die of it).  The book emphasizes, and I agree, that as you continue to practice fasting, somatic hunger sensations become less and less intense/distracting.
