    I started 18/6 IF in November, increased my exercise, continued eating healthy low carb/sugar & lost my final 20lbs (total loss 44). This has resulted in remission of my decade long type 2 diabetes! My BMI is 20.6, BP perfectly normal, RHR decreased to 62 from 75, off my diabetes meds, increased muscle mass (weights)...all this as a 63 yo woman! I am never looking back as this is my lifestyle forever, as I am healthier than I've ever been. Thank you for your review! The health benefits for me have been huge with ALL the changes, including IF.

    I don't eat breakfast, because I am not in the least bit hungry, so the food consumption timeframe for me is noon to seven. I don't have high blood pressure, diabetes, over weight issues, or high cholesterol. I'm a senior citizen, fit and trim, work out, and eat healthfully.
  • @brandonyoung4910
    Been using IF for 10 years. It’s made gaining fat very difficult. I think we will be fine
  • @mcc5295
    I'm fasting for 4 years now. Never felt better .
  • @hassb6348
    Hope this channel keeps growing. We need rational people interpreting science.
  • The biggest limiting factor is probably still how well you can stick with a healthy diet
  • @LeonCouch
    Thank you for addressing this question, at the request of your many viewers. I have my own field of study and work to maintain--rather than fully investigating every item in the "news"--It seems irresponsible of the media to have hyped this poster to this level. So, i appreciate the time you took to put it in context for people who have limited time and yet care sincerely about their health. The review of how to understand and evaluate medical news is also good. In the end, im concluding that some newswriters care more about eyeballs than us, the readers.
  • @JennWatson
    I love fasting! I'm 100 lbs down because of fasting! Thank you!
  • I was waiting for your contribution on this subject! Excellent as always
  • @carlr2837
    As I understand it, the people were assigned to the groups "8h" etc. based solely based on a questionnaire of when they recalled eating for the last two days years before filling out the questionnaire. Did they continue to eat in the same pattern for the next 8 years? There is no way to know.
  • I'm 76, started at age 70 with intermittend fasting , fasting from 16 to 18 hrs fasting, lost 70+ pounds, lost my high blood pressure, lost my borderline blood sugar and work out about 5hrs - my average bmi is 24+. Breakfast for me is around 11:30 am to 12:30 pm. I sleep good according to my fitbit for 6- hrs and feel better than I did at 56. Eat chicken meat or fish about 3-4 times a week and lots of fruit and vegetables - no alcohol and do not smoke. do not eat after 6 pm
  • @motherblank
    Gil- many thanks for continuing to inject reason and science into nutrition discussions.🙏 You’re the best!!
  • I once fasted for two days and broke my fast with an all-you-can-eat Chinese buffet. For three hours afterwards, my heart felt like it was trying to come out of my chest, and my pulse rate was 103 bpm, even with no activity. That scared me enough to investigate the correct way to break fast. It really did feel like I was going to die.
  • The more interesting conversation isn’t about the findings themselves, it’s about why the media pushed it so hard.
  • The irony is that I have seen so many IF "influencers" jumping on anything portraitaing IF as superiour, no matter how small. Everybody needs to chill out a little...
  • @realandsurreal
    You've taught us well that correlation does not equal causation! When I saw the headlines of this study I was hoping you would do a video about it. Thanks Dr. Gil!
  • @ssiddarth
    Was hoping that you'd cover this, and as usual you didn't disappoint. Thanks Doc
  • @DammikaW48474
    Thank you Dr. Carvalho for putting all this frenzy in context bringing sanity into the whole issue. Posters! Huh.
  • @alfonso365
    Great analysis... even with the little information available about this study.
  • @joseabboud2223
    Skipping breakfast is one thing and the opening hour of food is another. As you mention, doing fasting (forced fasting) and injesting junk food is deadly indeed. But if you have your breakfast at noon and last meal at 6 or 7 pm, you eat whole natural food (unprocessed), every single marker will definitely improve. Concering calories, it depends from where it comes from. So yes, focusing on what you eat is crucial (that's the root of all evil). Fasting 14 to 16 hours, following a healthy diet will reverse many bad issues.
