My first few fasting days were tough. Not being used to hunger is a hard thing. It seems like a monster at first. For me, once that "dragon is tamed" as Dr. Johnson says, fasting days have become fun and productive. Not spending all the time associated with meals allows me to spend time productively doing things I want. I already know I'm having Miracle Soup, a Salmon Veggie soup, some salad veggies, and very low-calorie drinks today. The disclaimer is that Trina and I are not even two weeks into the trial of the alternate-day diet and we are still learning a lot.
My sister we are visiting in Virginia makes very low-calorie teas using Crystal Light type of products. She has batches of peach and raspberry flavors made currently. I tried some yesterday and it tasted really good. Trina joked, "watch out tomorrow when he's on his fasting day because he will guzzle that stuff." Thankfully, she gave me the respective recipes for her peach and raspberry teas, and I'll definitely be making these when I get home to complement my normal drinks of water, coffee, and green/black teas. Dr. Johnson mentions in his book about having "go to" recipes for down-days (he recommends 5). I'm finding this is critical, especially as I'm not following his recommendation to use meal-replacement shakes and bars during this first two weeks. Trina is smart and eating the bars and shakes. So far, my go to recipes include Miracle Soup (basically veggies), salmon lentil veggie soup, and salad veggies (boat loads) with mustard (various types) and vinegar (tons of types work well for variety). I'm looking for more easy and quick to make low-calorie recipes to make as we continue on with the alternate-day diet lifestyle.
I am recording what I eat in MyFitnessPal. Based on goals I have put into the website, it tells me my goal calorie total per day is 1630. What I realized yesterday is that over a two day period, the number of calories Dr. Johnson calculates I need is equivalent to what Myfitnesspal recommends (about 3300 calories/day). I found it interesting as I was just reading Dr. Johnson's explanation on why calorie restriction prevents disease and/or delays the onset of age related diseases. The theory is CRON introduces "hormesis," which means that a harmful stress if taken in large quantities is beneficial in small quantities. If an animal starves it dies, but if its diet is reduced to 60% calories, it lives longer in good health. "The physiological events that occur in response to a nonfatal stimulus constitute the stress response. At the level of gene expression, the stress response is believed to be initiated by SIRT1 activation. The downstream effects of SIRT1 activation include reduced oxidative stress and inflammation and reduced fat storage and anti-apoptosis (stopping the process of programmed cell death).
"In humans, as in animals, the stress response is probably "dose-related." That is, zero calorie intake every other day activates the mechanism more intensely than daily calorie restriction. But, as I've said, and as Eric Ravussin also determined in his 3-week study of volunteers who were employees in his lab (see page 42), most humans would not willingly adhere to an every-other-day eating pattern on a long-term basis. That said, the Alternate-Day Diet will activate the stress response to the metabolic and oxidative insults to which we are constantly subjected."
"Actually, as indicated by the study done by Ravussin and his colleagues that we discussed on page 65, eating 75 percent of required calories every other day activates the SIRT1-mediated calorie restriction mechanism, and we believe that this level of restriction for a 36-hour period of lower energy, as provided by the Alternate-Day Diet, is sufficient to turn on SIRT1, although not as intensively as lower intakes on the down day."
So, it is a long, scientific answer to why alternate day fasting may be more effective for the body than calorie restriction. Some people also find it much easier to stick with alternate day fasting. Dr. Johnson sticks with between 30%-50% calorie restriction on his "down-days" to maintain weight loss and battle his "natural inclination to overeat". He gives reasons for up to 50% calorie intake on down-days as: it activates SIRT1 (with its health benefits), and its the level at which I'm most comfortable and don't gain weight.
Time to enjoy the next part of my fasting day!
