Quick, if you told anyone that you were fasting to lose weight, they would probably think:
a) You’re crazy
or
b) You’re crazy
It’s sad, but anytime you tell someone that you’re fasting, the only acceptable reasons for doing so are for medical or religious reasons. If you even mention the words “weight loss” and “fasting” in the sentence, then you’re in for a world of hurt.
But in my opinion, fasting for the sake of weight loss isn’t crazy. Not at all.
In fact, strategically fasting everyday for 16 or even 24 hours can provide a whole host of benefits over the conventional “eat breakfast and 6 meals per day” saying.

Basics of intermittent fasting
So what exactly is intermittent fasting (IF)?
Simply put, IF is the act alternating periods of fasting (not eating) and eating. While there is no official IF program, most programs range from 12-24 hours of fasting.
So why is Intermittent Fasting awesome?
Well lets see:
- You get to eat bigger meals
- You get more work done since you’re not eating as often
- You have more energy since you’re not bogged down by food
- You get to stick your middle finger at every single fitness guru who says eating every 2-3 hours is absolutely necessary for good health
I could go on and on.
Is IF unsafe?
In short, IF is safe.
However, just like everything else in life, if you overdo it and take it to the extreme, then it will become dangerous. If an intermittent fasting program tells you to fast for 16 hours, you shouldn’t disregard that and decide to fast for 100 hours.
As long as you don’t do anything crazy like that, then there’s really nothing dangerous about IF.
But won’t fasting make me fat?
I never really saw the logic in this statement, but since when the hell did not eating make you fat?
But anyways, many people have this ludicrous belief that fasting will make them fat. This belief originates from mainstream media where they constantly promote the fallacy that fasting will force your body hold onto its body fat and make it burn muscle instead which is just incredibly stupid.
Will IF make me lose muscle mass?
When it comes to fasting, another popular myth that people believe is that fasting will make you lose all your hard earned muscle mass. This is simply not true and as long as you perform of heavy resistance training 2-3 times per week, then you shouldn’t fear about losing any muscle mass.
If you need further proof, check out this research study. In it, scientists showed that even when people ate a super low calorie diet (800 calories per day), they were able to maintain all their muscle by lifting weights. The reason behind this is because the act of lifting weights sends a signal to your brain that you want to preserve all your muscle mass.
But don’t you need to eat more often to have more energy?
This is exactly what food companies thrive off of. They create all these products that target people who need a “quick energy boost” or a quick afternoon “pick me up”.
But in reality, these people probably don’t even need these products. They buy them because they fear that they’re suddenly going to crash and burn when in reality nothing is really going to happen.
If you just give your body a chance to experience what it’s like be without food every 2-3 hours you’ll realize that you’ll actually have more energy than ever.
Just give it a shot.
IF is just another way to eat
Even though I love IF and would NEVER go back to eating 6 times per day again, I have to admit, it’s just another tool. It’s another tool to help you lose/maintain weight.
Unlike most fitness professionals, I’m not going to tell you that it’s 100% necessary to do something. I’m not going to tell you that it’s absolutely mandatory to do IF because honestly, it’s not for everyone.
Some people just love to eat small meals every 2-3 hours, and if you’re one of those people, then that’s cool. I’m not gonna judge you.
But if intermittent fasting sounds good to you, then check out the 3 most popular IF programs below.
A look at various IF programs
Over the past couple of years, more and more fasting programs have come into the market. IF is slowly growing in popularity, but here are the 3 most popular forms of IF:
1) Eat Stop Eat
Eat Stop Eat was created by Brad Pilon is now arguably the most well known form of intermittent fasting. I’ve been using this program for the past 3 years, and if you read my blog often then you know that I absolutely love this program.

Eat Stop Eat requires you to fast for 24 hours (e.g. 7pm on Sunday till 7pm on Monday) 1-2 times per week. On the other 5-6 days of the week, your main goal is to simply eat normal (maintenance calories).
The whole goal of fasting 1-2 times per week is to let those days create a calorie deficit of 10-15%.
Important Eat Stop Eat notes:
- Even though you’re fasting for an entire 24 hours, this doesn’t mean you get a free pass to the all you can eat buffet. The main goal is to simply eat normal after each fast. Don’t over or under compensate for anything.
- Despite fasting for 24 hours, you still get to eat every single day. So for example, if you start a fast on Wednesday night and end it on Thursday night, that means you get to eat a meal on Thursday night. Awesome, huh?
- Eat Stop Eat is more of a lifestyle change than an actual diet since you’re only eating less for 1-2 days of the week.

2) Leangains

And now we have Leangains created by the oh so famous Martin Berkhan (seen above).
But unlike Eat Stop Eat, Leangains has a much larger focus on pre/post workout nutrition and macronutrients.
With Leangains, you’re fasting every single day. Men will fast for 16 hours and women will fast for 14 hours.
While many people have effectively used Leangains to lose weight, many people have also used it to effectively pack on muscle mass. But not only is this muscle mass, it’s lean muscle, meaning minimal fat gains hence the term “Lean” gains. This is achieved though calorie and macronutrient cycling. If you’re ever looking for a program that lets you pack on muscle with minimal amounts of fat, then this one’s for you.
There are a couple different variations on Leangains, but all every one has you taking 10 grams BCAA before workouts.
I don’t want to delve into the rest of the details but if you’re interested in the rest of the Leangains protocol you can read the Leangains guide here.
3) Warrior Diet

And lastly, we have the Warrior Diet created by Ori Hofmekler.
This form of fasting to lose weight isn’t as popular as the first two, but it was the first form of IF I tried and till this day, I still use it from time to time.
The Warrior Diet has you fasting for 20-24 hours every single day, so it’s similar to Eat Stop Eat in terms of the fasting length.
During your fasts you can still drink water and zero calorie drinks like tea, coffee, and diet soda.
But the main difference here is that you’re eating all your calories in 1 massive meal per day. The mainstream media will probably never promote this way of eating, but hey, it works.
I’ve done it in the past, and you really don’t feel hungry while fasting. Plus, every day is like a mini feast since you get to eat a crap ton of calories in one sitting.
4) Honorable mentions
Some other great intermittent fasting programs include:
- Intermittent Feast By Nate Miyaki
- Fast 5
So which program is best?
Whew, all this fasting talk has gotten me a little hot. And hopefully I’ve gotten you a little bit excited too, maybe even got your nipples hard.
But if you had to choose, which of the above 3 is the best intermittent fasting program.
Well… I don’t know.
It’s really a personal preference. I’m not going say that Eat Stop Eat is the absolute best IF program out there because it’s not. It’s one of the best, but it’s not the absolute best.
Some people don’t like to fast for 24 hours and that’s fine. In that case, you should try something more along the lines of Leangains.
And if someone likes to come home from work every day and just stuff their face with food, then the Warrior Diet is probably best for them.
In the end it all comes down to choosing a program that fits your lifestyle.
Fasting to lose weight = not crazy
Seriously guys, fasting is not as crazy as you think. You’re simply waiting longer between meals.
But to be able to effectively use intermittent fasting, you need to have an open mind.
You need to be able to let everything that you thought you knew about nutrition and dieting behind and be able to step into this new world of “not eating”.
But trust me, once you starting fasting, you’ll never want to go back.
Have you ever tried fasting to lose weight? Did you like it? Let me know in the comments below.
I am a 64 yr old women and 243 lbs. I have been doing the 24 hr alternate day fasts for a couple of weeks. For health reasons I cannot exercise much, and I have cut out grains, potatoes, and sugars out of my diet at my doctor’s recommendation. I’m discouraged because I do not feel like I am losing weight like I thought I would by fasting and the low amount of calories I am eating.
I eat loads of fresh vegetable and fruits, basically as much as I want. I eat small amounts of meat 3 or 4 times a week, and a little dairy. I eat till I am stuffed at every meal, but the most calories I have consumed in a day is 1400 (3 meals), and on the days I am only eating 1 meal, the biggest meal has been 990 calories.
I was reading your comments to others who were eating very low calories, and you told them it wasn’t enough for their weight. So is my low calorie intake why I am not losing weight faster at 243 lbs? How many daily calories should I be shooting for? How much weight can I expect to lose weekly or monthly?
Well there’s always the chance you’re eating a lot more than you think, maybe you’re miscalculating.
At your weight and age, you should be losing at 1-2 pounds per week at if you’re eating 2000 calories.
We also have internal fat or weight that surrounds our organs. You can burn and use up the fat there first depending on your genetic make-up and you wont notice much of a change on your external figure. We also, in a general term, lose fat overall as in lay by layer not section by section. And given your starting weight it can be difficult or easy to notice a change. An individual the size of say 300lbs will burn fat as much as a 150lb individual, but the lighter individual will notice the change quicker due to already being at a lower weight. So, closer to seeing the color bones and such.
I’m 25 years old and I lost 40 pounds in 6 months using IF. I didn’t exactly follow any strict program. After reading this article, it seems like I’ve tried them all. It’s second nature to me now and I find it to be the most effective way to lose weight! I love it!
🙂
I interested in every other day fasting, which day should i exercise (bodyweight only), on the fast-day or on the eat day?
doesn’t matter.
So is it ok to do IF every 24 hours every day or every other day?
You need to remember that fasting doesn’t make you lose weight any faster than any other diet. It’s simply a way to condense your eating window so you can feel more satisfied with your meals. So yeah you could do it every day…but nothing magical will happen.
Oh and also my only workout I do is the game zumba dancing…..three times a wk….just started….so is that ok while doing IF…..or do I have to b working out more …..cuz im not able to go to gym being a mother of two lil twins in all….
THat’s fine but that won’t necessarily help you build muscle.
Oh ok thanks a bunch!
This was so freaking helpful! Thanks a ton for posting this! 😀
You’re welcome 🙂
Hey. I’m a normal bodied 18 year old male I’m trying to get cut and tone.fast. I want to try and be a stripper because college is expensive I am 240bls and 6,3. Can you make any suggestions on which work out and fasting would be best?
Not sure if you’re joking about the stripper thing but more power to ya.
ANy approach is fine, you need to experiment to see what works best for you.
Hey I always hear “nutritionists” say, “you shouldnt eat more than 24 g protein in a setting cuz youll crap it all out lol. Ive always thought it was ridiculous… is there any research or studies or sites I can be directed to about this?
Also, ive done leangains a few weeks at a time and I wanna try warrior. Do you need to get your daily caloric needs in the same amount as if a regualar diet schedule? Or would it require more or less cuz of 24 hr fasting
Thank you. Great info
No total BS.
There is some newish research showing that you should consume protein in more smaller, more frequent intervals to maximize muscle growth but even then I don’t worry too much about it.
“Do you need to get your daily caloric needs in the same amount as if a regualar diet schedule?” The same.
Thanks man
Hello,
I’m a 22 year old female, 5ft 7″ in height and weigh 12 stones 8 lbs. I’m currently overweight and want to loose an average of 36 lbs to reach my goal weight of 10 stones.
I want to try the warrior diet, will I have to eat ALOT of healthy foods and workout whilst on this diet? Also, I know this shouldn’t be important but how long do you reckon it would take me to loose this weight – If I eat healthy and workout to maximize efforts?
Thank you!! 🙂
Kind regards
Sally
Of course you should eat healthy. The warrior diet isn’t an excuse to eat crap. It’s simply a way to backload the majority of your calories into one meal.
Time frame? At least 6 months, realistically closer to 8.
I’m 58 and, having been thin most of my life without effort, I now put on weight if I even think of food. I’m trying the one meal a day approach and it suits me much better than trying to cut down to smaller meals. I’ve been doing this for two weeks. The first week I lost about 3 kg. The second week I’ve lost nothing. Seems odd to me, but the eating pattern does seem to match my natural Owl metabolism.
First week was most likely just a lot of water weight lost. Weight loss isn’t linear so just stay consistent and you’ll lose it over time.
Hello,
I’m 50 years old male, 5’11” weight 223.5 lbs. I have on 24 hour fast twice a week for two months now. In addition to fasting on non fasting days I reduce my caloric intake by 25% ( which is about 500 calories ). I lift 5 days a week and do HIIT cardio 3 days a week and a steady state cardio twice a week ( each session burns 500 calories ). Despite all the effort in two months I lost only 5.5 lbs. By my calculations, just from caloric deficit, I should be loosing about 2.5 lbs. What Am I doing wrong?
Could be a lot of the different problems. Are you tracking accurately? Are you eating in a deficit on fasting days? Have you gone too low calorie in the past and maybe screwed up your metabolism?
Hi Keith, thanks for a prompt response. I have not really dieted or fasted prior to November. On days that i do fast I actually don’t eat anything.
Is is possible that I do too much in terms of caloric restriction and working out? If that is the case, would you advise to either limit the cardio or eliminate the caloric restriction on non-fasting days ?
yes that’s definitely possible I never recommend fasting for that long.
Hi my I’m a 17 yr old guy that is 5’11 and weighs 210 pounds. I do have muscle mass and it’s obvious, but I can’t seem to cut down and I need to get a four pack by the 1st of March. This was a personal goal 2 months before New Years and I’ve been in the gym everyday sense I was wondering what the best solution to this will be
Eat less, get in a calorie deficit. That’s it.
IF can help you get there, but find what meal frequency works best for you and helps you stay on your diet the best.
Hi I’m a female 36 years old. I eat plant based mostly with occasional cheese, almost never touch gluten, refined sugars, processed food or ever eat out. I’ve been fasting for 12 to 14 hours everyday for 3 weeks and my meals after are a probiotic, nutrient and protein banana smoothie, vegetable soup and some lentil tempeh. These meals never exceed 1200 calories but even though I only have 10 stubborn pounds to lose to be at 120 which is my ideal wight, the scale has not budged a pound. What am I doing wrong? How can i get rid of these last pounds which are not easy to understand when you eat so clean?
thank you
It has NOTHING to do with eating “clean” and more so to do with how much you’re eating.
How much do you weigh now? Maybe you’re eating too little.
can you drink water and coffee while you fasting
yup, but i would stick to black coffee.
