I have history of diabetes in my family ( south asian) I took the 23andME test and the report said i have a pre-disposition to diabetes at around age 50. I am 50 now. I have been working out running most of my life but started doin less miles and i packed on a few pounds maybe i was like 188-192 and i am 5' 11" About 2 years ago i was diagnosed with pre-diabetes the doctor said you need to get you A1-C down. I was like i have been working out all my life and now this! ok so i started looking into IF ( found some good videos by Dr Jason Fung) so i tried it and started not having breakfast ( I was eating a chocolate croissant from trader joes typically) i went black coffee. Giving up breakfast was damn hard after 6 months i got used to it so the next jump was giving up lunch i got hunger pangs and it was very very painful NOT to eat lunch but to my surprise i got used to NOT eating lunch and fast forward 2 years today i fast all day and my first meal is 5pm and usually a big salad and i feel fantastic all the hunger pangs are gone now i don't know how to explain it but water is sweeter and even black coffee taste sweet to me i am down to like 170 now and have an unusual mental clarity from NOT eating i know it sounds funny but i just do. Headaches go away. IF worked for me and i tell all my friends to at least try it and if you don't feel better than stop. SO I eat around 5pm and last meal and maybe a snack around 9pm. I don't eat after 9pm until the next day 5pm. Next goal is to try a 48 hour fast wish me luck. I feel f-in fantastic! -2cents.
