Why Skipping Meals and Workouts is Healthy

By Mark Sisson
73 Comments

Conventional wisdom tells us that “grazing” is the optimal way to eat. Constant snacking; more frequent, smaller meals rather than the classic breakfast, lunch, dinner set-up; and an ever-present fear of hunger as the enemy: these are said to line the path to healthy weight loss. If we ever feel hungry, it says, we leave ourselves vulnerable to temptation and metabolic imbalances. There is certainly some validity to this idea. I can imagine Grok roaming the grasslands for nuts, bugs, roots, shoots, and small game. And at times these foods may have been plentiful. More likely though Grok’s eating pattern was much more sporadic. There would have been periods of grazing coupled with stretches of famine and punctuated by instances of all-out feasting. As is so often the case, CW has cherry picked one part of this scenario and turned it into an ironclad, dogmatic proclamation that excludes any alternatives, whatever their potential benefits.

It has become sacrilege to skip a meal. Skipping meals, they say, only slows the metabolism, promotes fat storage, and makes us more likely to gorge on unhealthy foods once we do decide to eat.

The same goes for workouts. Missing a workout – especially in conjunction with a skipped meal – can make a fitness buff feel like a lazy slob. Missing two, or even three? A crisis of monumental proportions! A cascade of guilt and regret!

What are we to do?

Armed with a fresh perspective you can reframe your actions and toss fear and guilt out the window.

Say you aren’t hungry – should you feel compelled to force something down? Or maybe you only have access to a snack machine – should you eat a bag of chips just for the sake of eating?

Or maybe you’re sore from the previous workout session and it’s cold and the gym is a long drive through traffic – should you torture yourself and force the workout?

Sometimes, you should just say no. You’re not gonna starve if you go eight hours without eating. Your body isn’t going to immediately start burning muscle for energy if you don’t get something, anything, into your system (especially junk food). Your muscles won’t deflate if you miss a workout. The gym won’t close, and your weights aren’t going to rust over into obsolescence. You have to say no and be okay with saying it – no guilt involved.

The fact of the matter is that there are real benefits to both. I’m a big proponent of intermittent fasting as a way to promote health and longevity, maintain weight, and build lean muscle. We’ve got the studies that seem to back it up, plus my own success with it, but you can also look at it from Grok’s perspective. Our ancestors didn’t always have ample food. Sure, he undoubtedly preferred to constantly graze, but there were no guarantees. You think Grok felt guilty about missing a meal? No way. Maybe a little peeved, but not guilty. It just made the next meal all the more delicious.

Similarly, Grok wasn’t constantly working. He had plenty of time to relax and rest his muscles. Even (especially) top lifters stress the importance of rest in developing lean mass; if you overwork or overtrain, you’re only doing your muscles a disservice.

So what did I mean by reframing your actions?

With a slight change in perspective and a little “presto chango”!

The “my metabolism is going to shut down” Skipped Meal becomes an experiment in Intermittent Fasting

and

the “I’m a lazy slob” Skipped Workout becomes a “time to give my muscles a chance to rebuild” Recovery Day

In other words:

Skipped Meal = Intermittent Fasting

Skipped Workout = Recovery Day

Luckily, this isn’t just wordplay, and isn’t simply an attempt to see the glass half full. It also isn’t permission to completely slack off. You still need to eat plenty of healthy fat and protein (with a few carbs sprinkled in, if you please), and regular exercise is an important part of staying healthy. But missing a few meals every now and then won’t kill you and it can even be a boon. Nor will taking a couple extra rest days set your fitness goals back by any considerable amount (it might even give you the rest and resolve needed to assail your workouts with renewed vigor). So next time you’re faced with a non-Primal meal you’d rather avoid, or you just can’t muster the energy to drag yourself to the gym for the fifth day in a row don’t beat yourself up for slacking off. Pat yourself on the back for making a perfectly Primal decision and get on with your life.

Thanks Mark! I did the exact re-framing you describe, by telling myself that skipped meals were simply an experiment in Intermittent Fasting. So far, the experiment has been a genuine success: I think it has leaned me up slightly, and at the very least it has given me a huge renewed appreciation for the joy of eating. The first meal after a fast (even after just 12-15 hours) tastes just a little better than usual. Next it’s time to work on re-framing to the “recovery day” principle. I totally get this intellectually, but struggle not to judge myself as lazy/weak… Read more »

Great post. I’m a big fan of leaving some room for “intuition” in a training plan. I do think it is fine (even good) to listen to your body and skip a session when needed. But I also think that the body does a fair bit of unnecessary whining that needs to be ignored if progress is to be made. The body likes itself just the way it is-you need to push it into its discomfort zone if you want it to change and improve. That discomfort zone can be a great excuse for skipping a session without reason… As… Read more »

I’ve found it more practical, and natural, to eat 2 or 3 small meals early in the day, adding up to around 30-40% of total calories, and then have the remaining 60-70% of my calories in a 2-3 hour time frame at night. If I eat nothing all day, my metabolism does definitely slow down as evidenced by an inability to move or think, lol. If I eat even meals all day, I feel bad. If I fast, I feel bad. Snack sized meals plus a large meal at night feels natural. I think we assume humans “naturally” go long… Read more »

There seems to be some significant dimorphism between the sexes on fasting from what I’ve read. Men seem to get a more significant kick of testosterone and human growth hormone out of it. I certainly feel the opposite of ItsTheWhoo — fasting definitely kicks in my fight response and gets me primed for action.

I’ve actually just purchased Eat Stop Eat. Haven’t read it yet, but started IF anyways. The first time I brought lunch just in case. I’ve only fasted three times so far but it seems easier when I’m fasting. Less hunger than if I did eat in the morning. Also worked out after fasting for like 17 hours or more and seemed to have no loss of anything. Though I was sore for a lot longer but I’m attributing that to more squats and a higher weight on the dead lifts. Of course I can’t prove that it wasn’t the fasting… Read more »

To respond to Robert M –

IF is tough for me (as a woman)- tougher than it seems like it is for most dudes, but it gives me great energy during the day if I stick to it, and makes me feel extremely refreshed the next morning. As for speeding up my metabolism, not sure. But I dig it!

My friend who recommends IF to his clients (he’s a personal trainer of figure competitors) says that women always seem to have more trouble than men when they start out. He’s not sure why. But after 4 or 5 days of consistently skipping breakfast and not eating until 3pm, most women’s bodies stop raging with hunger in the AM, and it becomes just as easy for women as for men. It’s all about what the body’s used to, and most women’s bodies (apparently) aren’t willing to give up the regularity they’ve been accustomed to as readily as men’s bodies. Knowing… Read more »

“There would have been periods of grazing coupled with stretches of famine…” Mark, this famine hypothesis is one I hear a lot. During the millions of years our gut was evolving, we were brainy hominids living in savannah. As mentioned in Taubes’ GCBC, the anthropological evidence of the hunter/gatherer lifestyle has shown that even in severe drought food was easy to come by. I rather like to think we have been and are such a successful species primarily because we knew how to get food in all conditions at all times. True famines did not occur until the post-agricultural era… Read more »

Now I don’t feel guilty for slacking off my workout for 6 days last week (felt sick…then lazy).

I also don’t feel guilty for eating very little on Sunday and Monday. I had a “girls” night out on saturday and boy oh boy I ate waaayyy too much. So, I was listening to my body, which said…don’t eat.

Probably early man ate in ways that varied tremendously. A great book for seeing a variety of modern diets (and the human condition in general)is “Hungry Planet, What The World Eats.” Granted we’ve populated the globe on a much larger scale at this point in time, but still, Grok is a symbol that spans a lot of time and geographical regions. There would have to be great variation in diet from tribe to tribe. We have knowledge and resources that Grok didn’t. I don’t think it’s about trying to replicate Grok’s life, only acknowledging that our bodies are operating on… Read more »

This was an intriguing post … I think there is a very fine line and it very much depends on where you’re at and the progress you’ve made with your fitness goals. For those of us who are very consistent with our workouts and might even obsess about missing one (I know I’ve been there myself), the mindset this post is advocating is great. The same goes if you’re dialed in with your eating – missing a meal or two isn’t going to kill you – it might even be good once in a while (I’m very interesting in learning… Read more »

I’m not sure ancient man fasted that much, but I am sure he rested when he was tired, something us modern people could learn from. Ancient man didn’t have TVs or computers to make him fat. Play was his pastime.

And with that I’m getting off this time-sink to go lift!

The lack of strict rules makes this life style so hard to understand and adopt for many. It’s what really appeals to me though.
People have a hard time seeing the difference between this permanent life style and a temporary diet
As for replicating Grok I think it’s a fun little exercise, but should not be taken too serious since we know way too little about how exactly he lived. It’s more important to realize that he didn’t live on a fixed schedule and didn’t have the same meals all the time

Like Wooo, I feel absolutely LOUSY when I try to impose IF. Although I’ve read a lot of the studies and understand the rationale and science supporting it, I wonder if we wouldn’t all be better off taking a more natural approach to food – eating when we’re hungry, stopping when we’re full, not eating if we’re not hungry – without *forcing* so many rules on it like specific windows when it’s “okay” to eat or not.

IF has helped me to distinguish between actual hunger and psychological hunger. If I’m like most people, then I’d consistently be “hungry” at 8, noon, and 5, as per the pattern that I’ve been trained to eat in. I agree with Sarah; eat when you’re hungry. But make sure that hunger isn’t just your brain saying, “Ummm… we usually eat now. What’s the deal?”

ItsTheWooo

Evan,
I think those pits of hunger (8, 12, 5) represent dips in energy, albeit mild ones. They aren’t “imaginary brain hunger” but simply very mild hunger that you can ignore. It passes as you burn more body fat and make more blood sugar (that is, as insulin drops and stress hormones/catabolism increases).

The fact that hunger goes away when we stop eating does not mean hunger is imaginary/psychological, all it means is that abstaining from food increases our body’s tendency to break down fat and muscle into food and to reduce the enzymes which promote fat storage and muscle growth.

IF doesn’t work for me at all, I get Reactive Hypoglycemia which is like Type 2 diabetes’ really annoying cousin, the pancreas and liver stop communicating and will either dump a load of glucose into the blood when I don’t need it, or not dump any when I do.

Great post! I of course do love the IF lifestyle….and think people still need to remember to eat real foods, not use it as a pass to binge, and keep it “intermittent”.

I think it’s the mental obsession to eat all day long (or thinking one needs food all the time) that is keeping people from finding success and happiness. If anyone is thinking more meals is speeding up their metabolism….well they are in for a surprise:

I generally have no problem going 24 hours each day without eating though
as my culinary skills improve I find
myself craving certain meals more often.
Generally I have a small breakfast (1/2 cup of fresh, heavy cream with berries
mixed in (my “cereal”) and then a decent sized dinner (e.g., 3 eggs over easy with 5 slices of (organic) bacon with
a fried onion).
An odd rule I do incorporate into my routine is that I generally won’t eat my next meal until after I have defecated 😉

I’ve incorporated IF into my weekly routine (one 24 hr fast)and I can always tell a difference both mentally and physically. It’s not “torture” and I don’t spend the whole day complaining about how hungary I am. I also have no problem with a high intensity workout while fasting. As Brad Pilon states in Eat Stop Eat, many cultures practice some form of fasting on a regular basis. One of his points is that it’s very difficult for us to consistantly eat well and IF is one tool that allows a person to eat “reasonably” without having to stick to… Read more »

I typically don’t eat during the day until I get home after work. Been doing that for several years now and it works very well for me. The first half of last year I didn’t work out regularly (maybe once a week) and I didn’t gain a pound. IF naturally works for me, and I don’t “impose” it on myself. It doesn’t work for everyone, but I think the psychological hunger can be a factor because it initially was for me. I typically workout in varying degrees everyday, and again don’t impose that on myself, especially if I’m not feeling… Read more »

While I enjoy doing some of Mark’s workouts and advice, some of the stuff he says is starting to bother me. Mark continually refers back to Grok as his ideal. Let me be one of the many to remind you that life expectancy in Grok’s era was dismal at best relative to modern times. Just remember to take what mark writes with a grain of salt. Remember to consult your doctor too! Don’t forget about the atkins craze.

I find it amusing that so many people think that going without food for 12 hours is a really difficult thing to do. Some religious people, for example, think a 12-hour fast is a HUGE SACRIFICE. For me? It’s an average day.

Of course, I’m not addicted to grains and other carbage the way they are, so it’s probably different for them. But if they’d go Primal, they’d probably find that their fasts become a lot less difficult to do. Oh, wait… doesn’t that reduce the “spiritual experience” and “sacrifice” of fasting? My bad.
