Starting Intermittent Fasting

February 10th, 2014 · 1 Comment

As described in a previous post I am trying the 2 days on 5 days off intermediate fasting protocol.

My baseline data before going onto Intermittent fasting is shown below:

  • % Fat: 21.5%

  • Height: 186cm
  • Nude Weight: 90.4kg (weight immediately before start of fasting)
  • BMI: 26.13 kg/m2

  • Umbilical: 101cm (relaxed)
  • Hips: 106cm (level of greater trochanter of femur)

Cognitive Test

  • Haven’t done yet


I am on my third fasting day today.  I will likely make my fasting days Monday and Thursday from now on.  I just wanted to get the DEXA Scan done before I started.  From what I have experienced so far intermittent fasting will be easy to maintain as the hunger isn’t too bad and you eat normally the following day so it is no problem.  I am purposely having my entire 25% kJ intake at night so that I have a semi-normal evening meal and therefore don’t feel overly hungry going to bed.  Also I wanted to maximise the length of time I was fasted to make my insulin levels as low as possible for as long as possible thereby promoting fat breakdown.

My first day of Fasting was Wed 5/2/2014.  I felt quite hungry by lunch, but just kept working.  Whenever I felt a pang of hunger I would drink water, not just as a distraction but also to make sure I kept hydrated.  For dinner I kept to my 25% of my recommended intake which for me is 2175kJ.  I had:

  • Meat Pie: 1070kJ
  • Frozen spring vegetables (200g): 2 x 181g = 362kJ
  • Ranch Dressing (15mL): 298kJ
  • Peach Ice Tea (600mL):  293kJ
  • Total = 2023.5kJ

I made my second day Friday 7/2/2014 so my fast days weren’t consecutive.  I felt noticeably less hungry on this day.  I had an aggravating night setting up a new printer I bought to get some DVDs printed that I needed to get done and didn’t end up getting around to dinner until 12:30am or so, so just didn’t bother and went to bed.  The next day I didn’t really feel hungry before breakfast.  I am surprised how quickly you stop feeling hungry on these fasts.  I expected to get more and more hungry until it was unbareable.  But the hunger is quite mild during the fast days and it tends to go away over night.

    Yeah it’s strange. Sometimes I get hungy after 2 hours, or when I wake up, but then it goes away and doesn’t bohter me (apart from the occasional pang). Especially if I’m busy I don’t think about food. I usually break the fast at noon, but that’s just because my watch tells me to (well sometimes)
