Yes. 23:1 to 22:2. For many years. My weight has been quite steady except for the past 3-4 years where it has a tendency to creep up. I’ve been quite athletic for most of my life. But there was a period of time in my early 30’s when for completely nonsensical reasons, I let myself go and gained 80-90lbs. That was bad. Looking at 40, I got a grip and lost all the weight by limiting my eating to just one meal a day. I also took up an intense exercise program, weights & cardio. Over a period of 12 or so months, I lost the 90lbs and gained lots of muscle mass. It was a complete lifestyle change. I was happy with my new weight of 165lbs but was at my personal best when 158lbs. I maintained those numbers in the years since. But in the past few years by weight has crept closer to 170lb and due to wear and tear, I can’t maintain the level of intensity in exercise like I used to. I don’t like it and I’m working on get back to my fighting weight. In my advanced mid 50’s, it’s much harder than it used to be. At 5’8", I’ve never felt or considered myself to be underweight. Also, I love food so there is little chance of that ever happening.
In the beginning, and very rarely now, I felt the lack of blood sugar as the day crept into mid afternoon. A nagging headache would be the worst of it. I felt hungry but not ravenous and was mostly unaffected by bad moods. Took the entire first year to get over the worst of the symptoms. Over the years since it’s been my normal. Now I mostly break my IF window out of boredom and/or stress rather than any specific physical need for food. Working from home has been a surprising challenge. I did not remember the kind of temptation being close to an always available food source presents. Also, the getting older part seems to introduce a flagging amount of willpower.
Time to do it again…
