I've been attempting to do caloric restriction and alternate day fasting for a while. I believe that they have additive benefits at least to some extent.
My current diet is roughly 2400 calories one day, followed by 600 the next. There is a 24 hr fast in there -- at 8 pm on the first day I stop eating and do not eat again until 8 pm the next day, at which time I eat the day's 600 calorie meal. Given my activity level -- I try to exercise every day for around 45 minutes, HR~160+-- and my weight (180-190 pounds) this ends up being CR at an average caloric intake of 1500 a day.
My main issue has been maintaining the 24 hour fast. However, I've also found it difficult to avoid absolutely splurging on non-fasting days. To counter this, I've been looking for ways to suppress my appetite. Coffee goes some of the distance, but I've found that a nicotine patch really suppresses my hunger and keeps my energy high throughout the day.
Based on the research, http://www.ncbi.nlm..../pubmed/8614291 for example, it seems that cigarette's deleterious effects derive primarily from the delivery method and not from the nicotine itself. So I'm not too concerned about chronically having a high level of nicotine in my bad. What's more worrisome is whether or not the actual experience of hunger is necessary to derive benefits from ADF or CR. The signalling in the body associated with hunger that I'm shutting off or quieting down with nicotine might be intimately connected with the stress response which causes the desired metabolic effects which lead to increased longevity.
I was wondering if anyone has done any research into this idea, and what (if any) results they found.
