Yeah I always joke that "intermittent fasting" is really just fancy jargon for "skipping breakfast" - at least it is for me. Don't eat till noon, don't eat after 8pm - congrats, you're part of the IF crowd.

And yes, it does seem to help burn a bit more fat than before - though I wouldn't call it life-changing.

These are the basics, yes, but it's not that simple. To me, IF means: from 8PM to noon next day drink only water and (if you like) one black coffee in the morning. Then, from noon until 4PM eat just proteins, healthy oils & fats and raw vegetables - this is crucial, absoultely no carbs! Finally, from 4PM until 8PM eat everything.

That way you keep insulin under control for the 20 hours (out of 24). Your concentration and focus will increase very soon.

Why only one cup of coffee? Is it the caffiene? Does decaf apply here too? (I work in coffee and often skip breakfast.)

Good question! I'm sorry I left out the details. Yes, it is the caffeine and the book I followed (The Renegade Diet by Jason Ferrugia) recommends 1 cup about 30-45 mins before the workout to burn fat even faster.

Even though I now rarely work out before going to work, I still start my day by drinking a glass of water and then a cup of coffee and it still feels good :) If you drink decaf, I think it would have no positive (but probably also no negative) effect.

I've been practicing IF for over 3 years now.

It hasn't been life changing in itself, but I found it to be beneficial for keeping my body weight stable, which in turn improves a bunch of other health outcomes. It could just be placebo, but I feel much better with IF.

Does it really work? I don't know, the scientific evidence isn't that strong at the moment.

But it has convex outcomes: if it works, the upside is tangible... and if it doesn't, the downside is negligible.

Going on two years of 16/8 IF myself, but I'd say that it absolutely was life-changing for me.

I initially lost about 45 lbs (217 – 172) in about 10 months, but have since leveled out between 170-175. Beyond the weight loss, I noticed marked improvements in general energy levels, sleep quality, and chronic issues such as heartburn. More importantly though, I think the biggest adjustment that IF enabled me to make was transitioning into _wanting_ to eat healthy/whole foods and cut out foods with processed carbs and added sugar.

But I totally agree, there definitely is a psychological aspect of it, whether the improvements are quantifiable or not. Maybe the results are placebo, maybe it's confirmation bias, but I definitely think that IF allowed me to reframe the way I approach my diet, and eat in a way that is more attuned to being healthy.

Huh, I've been doing this for years without realizing it. I'm never hungry in the morning except for coffee (maybe that ruins this). To add more to discussion I also lift 4-5 times a week. Besides obvious physical benefits of muscle mass lifting improves life in many other ways. I notice if I ever skip or don't stick to my regular gym regimen I mentally feel unfit. Going to the gym actually increases energy and allows more productivity at work, social outings, etc.
