hi Rob... i have been on an iF schedule for about 19 months now. most days i'm now on a 16/8 schedule, but i can't say i don't have some 14/10 or even a 12/12 day occasionally (like yesterday). it took me about 6 months to lose ~50 lbs and since then i have used it to merely maintain a BMI between 22 (as low as i ever got) to just under 24 where i am now. i have pretty much accepted hunger as a recurring urge that i often just ignore. even when doing a multi-day fast, there are hardly any stretches more than a few minutes that i feel a hunger attack. it's not like i'm suffering all day.
i tend to look at it this way... humans have evolved over thousands of years to rely on our natural senses to keep us alive. hunger is our mind reminding our bodies that it needs nourishment. now put an evolutionary sense like that into a modern society where food is not only easy to find, but plentiful. and don't forget to add in the modern innovations in food processing, most insidiously, the introduction of high fructose corn syrup into our diets.
there is no doubt left by all statistical measurement that, at least in this country, the general population is getting larger. it would be great if physical fitness would become a national priority again.
