🐰 TLDR: This article is about intermittent fasting, I do it and on most days, I Don't eat after 10 pm or before 1 pm. I exercise 30 mins a day (at ...

One little nutritional gripe here: it's better to eat a large breakfast, rather than a large dinner, because you have more of a chance of using those calories, and because it provides your body with the critical nutrients it needs to get through the day. You don't process those as effectively in your sleep!
Historically, that's the way we did things pre-modern-era. For example, many farmers would eat a substantial breakfast, a decent "dinner" (lunch), and a very light (if any) supper, perhaps just a bowl of porridge. Heavy physical exertion, especially outside, and early morning hours, contributed to a decently healthy lifestyle. Big suppers are the fairly recent invention; breakfast isn't.
So, the fasting time range you describe is actually contrary to standard nutritional rules. For a diurnal type person, it's infinitely better for health to eat breakfast and skip dinner, rather than skipping breakfast and eating later.
Avoiding breakfast has a significant impact on the metabolic system. It helps push the body into ketosis. The purpose of avoiding breakfast is that the body has used up much of the glycogen reserves over night. In the morning they are nearing, or have reached depletion. The next in line energy source is fat, which will be broken down to produce ketones.
There reason why intermittent fasting recommends breakfast appears to be because it's the easiest meal for us to skip -- as we've already partially entered ketosis over night, thus have some energy. Initially, it's the jump between burning carbs, and burning fat, that is hard to tolerate -- it can make you fell tired and lethargic.
Ideally you should avoid eating before you go to sleep, and also just after you wake up. If you like jogging, doing it in the morning is also great, as it's an activity that can be sustained by burning fat.
This is of course should have linked studies! There's too much info like this online without scientific backing. It's why I'm going to do try an source all my articles on my food blog, Edaqa's Kitchen. It's important you can understand why things like intermittent fasting work, and how to adopt them to your own lifestyle.
Huh, TIL. (I partially knew about the ketosis thing, but not the breakfast part.) Thanks for the info.
At any rate, there should be a giant disclaimer at the top of the any such article: talk to your doctor before undertaking any fast or significant dietary change. Every body is different! Various conditions, medications, and hundreds of other factors can affect the safety of any such diet.
I wonder if personal stories need such a disclaimer? I does clearly cross the line from story to advice, so probably.
I've got a disclaimer on my site.
Personal stories need no disclaimer, also I'm not trying to be cocky or anything but I feel that recommending that other humans eat and exercise the same way every other animal on this planet does, is not posing any health risk. Also I did put a disclaimer in the story. You see some people have insulin disorders and a certain type of diabetes that may require that person to consult a physician if they do something like this. I really do believe that humans at one point had to wake up hungry, hunt and kill food in order to eat. I feel intermittent fasting mimics that in some way and it's completely natural.
I'm glad some are passionate about health even if it's not what I subscribe to. I welcome all comments.
You should have co-authored the article with me! You are spot on. I also agree on not eating before bed. My last meal is between 7-8pm giving myself a few hours of digesting before I rest. I'm still trying to work out what is best, but I have never been healthier in my life. Again I have been testing intermittent fasting for about one year and really hitting hard in the last Few months (being more strict about not breaking my fast in the morning specifically and getting a workout inside the fasting window).
As a lifter and an aspiring natural bodybuilder I can summarize it easier if the goal is to lose weight: calories in < calories out - in a week timeframe (don't let fool yourself on dieting for 5 days and go overboard on the week-ends).
People complicate it too much.
Vouch. I lost 20 kg using a very similar approach. Initially I walked every day for one hour and fast 6pm till 6am. Once walking didn't felt like much I switched to rucking, started with 10 kg and now I do 20. Best thing ever.
Great job!
I had to look up "rucking". So, walking with a heavy weight on your back. When I started my journey I rode my bike to the grocery store. The way back was with a filled backpack. :)
Yep, think "Ruck sack". Military folks train like this to get them ready for lugging around a tonne of equipment on their back. I can't ruck because I have a sore spot in my back, however; I have noticed after getting in shape that the sore spot is less of a problem for me.
I'd like to hear more about your story and your regimen!
Excellent job in regaining control of your weight. It's nice to hear these stories.
I think it's important to note what exercise you were doing. In particular there is a significant difference in dietary requirements between a low-intensity and high-intensity workouts. The high-intensity kind, generally involving weights, do require you to eat following the workout. IF you do not, you may be promoting muscle loss. If you're doing low-intensity, like jogging, then burning fat alone should be enough*.
*I put a star there, since when you start out, your body won't be well adapted and doing anything during ketosis can feel challenging.
Also, be sure to drink a lot. Going into ketosis appears to use more water than burning carbs (not just the water lost that was stored with the glycogen). IF you fast long-enough, or find yourself getting headaches or muscle cramps, you'll likely need some electrolytes (salts) as well.
Also, I would like to post some before and after pictures. Let me see what I can find. When I started my fast I worked at Tesla and I have some images of me presenting at a meetup vs my latest pictures. I think If I can find those I will be able to show the results.
Before:

After:

I will try to find better images! believe it or not, there is a 30 lb difference in those to images, at the lest a 25 lb difference.
Thanks for sharing Eric. I am a developer advocate as well. And my weight has started to affect my confidence when I am in front of an audience. I recently started IF and I am hoping to see positive changes as you did ! Well done and good luck with everything.
Hit me up on a direct message if you want to hop on Slack or Skype anytime. Would love to share or learn what you are doing each day!
Yes, I will say that I never do weightlifting without eating protein first, my workouts that I do on my fasting regimen are mostly running on a treadmill, elliptical machine and small weights high repetition and many sets.
Yes I believe it is a misconception that you need to always eat breakfast - there are a lot of very successful people that regularly skip it (mentioned on Tim Ferriss' podcast). I just have coffee in the morning and am not hungry before lunch. As for the meal plan, I'd recommend a more diverse diet, bump up the vegetables, add healthy oils and spices to make it tasty otherwise you'll get bored with it. For exercise, much better to get out in nature when you can rather than do a routine in a gym. For me, mountain biking and bouldering in gyms has been the ticket to fun workouts. But I'm still 1/8th of a ton so I have work to do...and btw I think you mean regimen rather than regiment...
I did and I corrected it! THANKS
hmm I vouch for intermittent fasting, it has worked wonders for me. I went with fasting between 6pm and 7am. With an hour of walking first time in the morning and other at the evening, I've lost 12Kg in 40 days.
But I won't subscribe to the conspiranoic theories, I don't see a "you've been lied to" scenario, but a "established dietary advice is designed for FAR less sedentary lifestyle".
I was doing the intermittent fasting thing for awhile then I fell off the wagon. Your article has encouraged me to start again. My time frame for fasting was 7:00 PM to 10:00 AM, as that worked better for my schedule. Do you think it matters that much? If it does, I could try your schedule for awhile.
I don't think it matters as long as there is a time period you don't eat.
Getting fit and loosing weight are very different things ...
Agreed. If a skinny-fat individual with sedentiary lifestyle just do a diet without a minimum strength training program it will look just leaner, not "fit".
Lesser bodyfat, without a decent lean mass =/= fit.
This is why I share my regimen, the regimen is key to not only losing fat, but getting fit. Yeah I chose a catchy title that would get people interested. Sue me!
JK of course. Please don't sue me!
No problems, I was just pointing this out the differences, but I understand the use of the title.
Not in my book, I'm doing it all at the same time and using IF to get me there faster. And I say it's not a cheat.
Awesome work! I saw your before/after pictures below and you have really come a long way!
I also follow a similar eating window, though because I wake up so early for the gym my hours are different. I hit the gym before work, then all my food is between 9am and 6pm with bone broth to wake up my digestive system around 8am. I do three meals a day and follow a very low carb diet with the majority of my carbs coming with breakfast in the form of veggies like broccoli and carrots.
My fats are moderate and protein is high, and I don't get affected by the dreaded "keto flu" so I allow myself to bounce in and out of ketosis (a process called gluconeogenesis allows the body to produce glucose from protein instead of carbohydrates, which keeps the body out of full ketosis after high-protein meals). I'm one of those people who feels best on a no-carb diet though, so this certainly won't be the case for everyone.
@ben has a pretty intense IF schedule -- I think he does 20:4?
I'm on the keto diet and do a 16 hr fast :)
Hi Jess,
We'd love to hear more about what you do! ALSO do you listen to "Two Keto Dudes" podcast?
I’ve been doing the same thing recently and noticed a huge difference.
Throw in a solid compound workout routine & you’re going to see some amazing results
Yep, I do a little cardio each day as well as a compound workout.
I have lost 34lbs and still progressing and have found this is an excellent routine for me. Also solved some gastro issues I'd had for years. I've also chosen to lightly pick up running and found that to be great for some stress relief and for my body's endurance.
Glad it works for others like yourself too!
I have heard wonderful stories about acid re flux and heart burn issues completely disappearing. As well other gastro issues. So great to hear.
My exercise routine includes two balanced calisthenincs/gymnastic strength training inspired workouts a week, and two yoga classes. I do stretching/mobility work pretty much every day. Minimal cardio (walking is enough for me). I experiment with IF - every few weeks I'll go 24 hours, which I find pretty easy. Definitely think it's a good idea to pay attention to what the body is asking for and when it's asking, than just assuming that the three meals a day default is what is right for you.
Human bodies have untapped potentials and it's amazing the progress we can make with some dedication and education!
Are you sure not eating before 1pm is healthy?
Yes, I studied intermittent fasting for about a year before trying. I would tell anyone that it takes getting used to. But there is no studies I can find that show in any way that it is unhealthy, in fact quite opposite. I have heard negative things about Keto and all Meat diets. If anything doing intermittent fasting, it has guided me into a better diet and I have more energy, etc.. It forced me to understand the delicate balance of what's going into my body and how I can change due to those inputs. I'm a much healthier eater, I eat less meat than before and any meat I eat typically goes down with some type of greens now. As with any regimen, when you start losing that much weight and start feeling good about it. You change your diet along the way to help accelerate the process.
Great post! Have you tried squats & kettlebell swings? I've found that those really help me slim down and also build muscle at the same time.
Squats yes, kettle bell swings no. I'm thinking about getting a few kettle bells though.
Fasting fasting, and what it is?
