I’ve personally experienced major results with a 16 hour intermittent fasting program. I’ve achieved visible fat loss, and measurable strength gains simultaneously. Whether you’re trying to gain muscle, lose fat, or just be a more healthful resilient person, intermittent fasting might be a lifestyle habit that makes sense for you.
For the past 3 months I’ve been following an intermittent fasting program. I had heard about intermittent fasting and read about it in a few articles well over a year ago, but never really got inspired to give it a try. After all, doesn’t eating inspire metabolism? Aren’t you suppose to eat many small meals throughout the day or ELSE you’ll lose all your hard earned muscle and waste all those hours of hard work? Well the reality is all those old conceptions are myths and have no scientific backing. It took bumping into a few sites and learning from a few sources for me to start to question all the ‘gym bro knowledge’ that I’ve heard for years to give it a try. After only 3 weeks, I could already tell that I’d likely be committed to this way of eating for life. I’ve already seen fat loss results while also gaining strength. This indicates a REAL body re composition where I’m gaining muscle while simultaneously losing fat. I’m feeling more energy (especially in the mornings when I’m fasting). And there’s something within my intuition that tells me this is a more healthful way of living.
Why Intermittent Fasting Makes Sense To Me
When evaluating how our bodies evolved, it’s seems reasonable to think that the human body was in a fasted state a lot of the time. Maybe not by choice, but by demand. Food is scarce in the wild. There is no tupperware, no microwaves, no packaged convenience foods. Hunting and gathering takes effort (aka exercise), and often coming up empty handed and remaining hungry would be unavoidable. This is why the human body is extremely effective at storing fat (I know from experience). In other words, in nature food was probably scarce for most of human evolution. Human beings definitely weren’t pigging out continuously, and most likely the feeding times were irregular and erratic. So what is the point? Replicating conditions of how the human body evolved will likely provide health and wellness. Read more about this concept here. So the point is, that the human body evolved to have times of being fasted. aka not fed.
Fed vs. Fasted
If you look at modern society, we rarely let ourselves go fasted. I was under the impression that it was a muscle building sin to not have something in the stomach at all times. I don’t know what it’s like to be on steroids, I have never done them, but it seems like most of the ‘never let yourself go hungry’ preaching is coming from the bodybuilding community (the gurus being steroided up). At one point I listened to this preaching without question or critical thought. However, it just didn’t work for me. I found it nearly impossible to actually lose fat, I felt like crap alot of the times (especially in the afternoons), I was drowsy and un-alert, and looking back on it now I just didn’t feel vibrant and healthy.
Even if you’re not into fitness and bodybuilding, the average population (in the USA at least) is in a fed state continuously throughout their lives. Not only are we eating stuff our bodies weren’t designed for, we are eating too much, and too often. It makes sense to me that keeping your body in a ‘fed’ state continuously is going against our evolutionary programming and could be one of the causal factors behind diseases of civilization as well as the obesity epidemic.
Summary: Intermittent fasting makes sense from both a health and fitness perspective.
Intermittent Fasting Scientific Backing
There is an increasing amount of studies being done on fasting. The results are starting to compile and short-term intermittent fasting has been found to have the following health and fitness benefits:
- Decreased body fat & body weight
- Maintenance of skeletal muscle mass (you won’t lose muscle in other words, despite what the bodybuilding community falsely claims)
- Decreased blood glucose levels
- Decreased insulin levels & increased insulin sensitivity (avoiding diabetes and obesity is a good thing right?!)
- Increased lipolysis & fat oxidation (which leads to ABS)
- Increased Uncoupling Protein 3 mRNA
- Increased norepinephrine & epinephrine levels (more energy and ‘awakeness’)
- Increased Glucagon levels
- Increased growth hormone levels
If you’re a nerd like me and want to research the studies, you can find many of them here.
Intermittent Fasting as a Lifestyle
So how can you make intermittent fasting into a lifestyle/system/habit? Well the good news is there aren’t any hard ‘rules,’ only suggestions and principles. The principle is simple: let yourself go hungry occasionally. Some people (such as the author of one of the books I recommend called “Eat Stop Eat“) recommend fasting once or twice a week for 24 hrs. Personally, I’ve followed Martin’s program of daily 16 hour fasts. For me, this made sense as I’ve never liked breakfast anyways. Like I just mentioned, the whole ’3 square meals’ or ’6 small meals’ and ‘breakfast is the most important meal of the day’ fads are conventional wisdom hogwash that has been repeated so much that we assume it to be truth. The only problem is it doesn’t have any basis in nature or current research.
So basically I have my last meal at around 9 PM. I skip breakfast, do my workout routine with weights at noon in a fasted state (taking BCAA’s before my workout), and have my largest meal of the day at around 1 PM. From 1 PM to 9 PM. (P.S. I’m absolutely NOT perfect and have at least one day where I eat whatever I want. Perfection isn’t the goal, excellence is.)
Intermittent Fasting Program vs. Skipping Breakfast
I’ve had alot of people say something around the lines of “so you just skip breakfast, big deal.” Intermittent fasting isn’t complicated, but getting results with it probably entails alot more than just skipping breakfast, especially to get optimal athletic and aesthetic results. In other words, although skipping breakfast may be considered intermittent fasting, it’s not the full intermittent fasting program that has gotten me such great results. After much thought and study, an intermittent fasting program that will get you real results is much more than just skipping breakfast. It’s really about 3 things:
1. Fasting in conjunction with a workout routine and appropriate supplements
If you’re just skipping breakfast, it’s likely that you won’t be getting optimal benefits of an intermittent fasting program. Fasted workouts with the right supplements is what has gotten me results, not just skipping breakfast. Like I mentioned, after about 15 hours of not eating I do a fasted workout supplementing with 5-10 grams of BCAA’s, Glutamine, and sometimes Creatine monohydrate beforehand (links to my favorite supplements below).
2. Nutritional timing (post workout)
The intermittent fasting program I follow is all about nutritional timing as well. Specifically what I mean by nutritional timing is eating certain quantities of food around certain times. In other words, it’s much more than just skipping breakfast; it’s also about eating large percentage of your daily calories (up to 50% of your daily caloric intake) after your workout.
3. Appropriate calorie consumption
This is still the basis. You can overeat on an intermittent fasting program and see minimal (if any) fat loss. You still have to determine, or have an intuitive sense of your calorie consumption. If you’re trying to gain muscle you’re still going to need excess calorie consumption, and if you’re trying to lose fat you’re still going to need restricted calorie consumption. Intermittent fasting is a program that allows you to follow a system that keeps you on track in this regard. It’s not magic, and doesn’t make your body defy the laws of calorie consumption.
Fear NOT, Your Muscles Aren’t Going to Run Away, and Your Metabolism Is NOT Going to Crash
Alot of people who read this are probably in the same shoes that I was in before discovering intermittent fasting. That is, always being paranoid that if you didn’t have something in your stomach your hard earned muscles were going to rapidly disappear and your metabolism was going to crash, thus turning you into a fat blob. Probably the biggest takeaway you can get from reading this is simple: it’s okay to have an empty stomach. In fact, that’s exactly what you need in order to lose fat effectively. Your muscles aren’t going to run away, and your metabolism isn’t going to crash. Those claims are false ‘broscience’ that are incomplete summaries of ideas based on limited/incomplete understandings. I, and alot of other people, have found this understanding to be very liberating and helpful. For example, I no longer have to be paranoid about eating constantly. I use to think about this constantly. Hell, I’d even go pick up a candy bar if I hadn’t meticulously planned out my eating schedule to ‘preserve my muscles.’ Of course, this mentality only led to me gaining fat and not getting the results I was after. The bottom line is that with these understandings you are a lot more likely to achieve better results because you’re not consistently overeating due to inaccurate assumptions on how the body works.
If you’re just looking to lose some weight, maybe these aren’t critical; however, if you’re looking to maximize your muscle gain and rearrange your body composition they definitely are.

Call to Action
Ultimately, I believe intermittent fasting may be one of the most beneficial and EASY health habits you can implement for yourself. If this has peaked your interests to give it a try, I’d love to hear your feedback. Keep in mind there may be an ‘adjustment’ period initially where this may be no fun. Personally, once I got the mental belief out of my mind that I ‘needed’ food in my stomach constantly, I found that I really wasn’t hungry as much as I had anticipated I would be. In fact, I’m able to just forget about food in the mornings and I find myself more focused and productive because of it. I also find that I have increased mental clarity and ‘presence,’ as well as plenty of physical energy in the mornings and throughout my fasted workouts (I feel like an unstoppable beast lifting weights on most days). If you’ve already been trying intermittent fasting what have been your experiences? Results? Concerns? I look forward to hearing your response.
Eat Stop Eat
I’ve found that one of the most motivating forces is fully understanding the implications of certain actions. In other words, if you ‘sort of’ understand how intermittent fasting has potential to help you in your fat loss goals, it’s likely that you won’t be fully motivated to give it a fair chance and reap the full benefits of it. In order to make sure you fully understand the implications of intermittent fasting I HIGHLY recommend you continue to study this lifestyle in detail.
Make it a challenge for yourself to gain a detailed understanding of how intermittent fasting works and how you can really implement it into your life. Here are a couple resources you should check out.
Eat Stop Eat is the book that really helped me to understand intermittent fasting on a level that got me motivated to take action (and thus experience results). This book is probably the best condensed resource available on the subject. I am SO thankful for this book and I recommend it for anyone who has an interest in learning more about intermittent fasting. Was this whole page noting but a sales pitch? Absolutely not. Obviously my goal was to articulate my thoughts and experiences with intermittent fasting and provide value to those looking to get a more athletic and aesthetic body. However, like I mentioned above, to remain motivated toward making a lasting lifestyle change, you must fully understand and educated yourself on the implications of your actions. This book will allow you to get the details of intermittent fasting which will likely get you to take consistent action, get results, and therefore get you closer to the healthful, aesthetic, athletic body you deserve. The book is a simple read and the author breaks down and articulates important clinical studies in a digestible and motivating way.
