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.
You can red my review of Eat Stop Eat here.
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.
Hello! Like all the other people here, I will begin by telling y’all about myself. I’m 28, have 3 kids, I’m 5’10 & unfortunately weigh 232lbs & I need to lose 63lbs by April 7th. I did gain weight with my last child & I just can’t seem to figure out what would be best. I know it’s totally possible to at least ALMOST be to that 63lb loss goal, which I’ll take. I do have a work out regimen but it’s the food that idk about. I don’t mind fasting at ALL! Help if you can
thank you!
Wow that’s incredibly specific…why april 7?
Uh not to be a downer, but what makes you think losing 60+ pounds in 2 months is so easy?
That’s 30 pounds per month, which equals 1 pound per day which is quite unrealistic.
Hello Keith, i’m planning to start the warrior diet. Fast from 8pm to 6pm while drinking alot of water and eating 1 or 2 fruits. I currently weight about 110-115 and i’m 6’3. My goal weight is 90kg but would be happy if i can take myself below 100, doesnt really have to be 90. How long do you reckon it will take me to get my weight below 100kg with warrior diet? Thank you
Prob around 3-4 months realistically.
Hi there,
I’m a 48 year old female, 5’10” need to loose roughly 45 pounds. I started the 4:3 fast a little less than two weeks ago; don’t weigh myself but like how I feel and can visibly see a difference since the first 3 days. I also do weigh lifting plus cardio 3-4 times per week. My question is this: should I stay on the 4:3 or would it be ok to possibly do the 24 hour fast every other day OR maybe speed up results if I fast for 22-24 hours per day?
I started the warrior diet today. I haven’t eaten since 8:30PM last night. I lifted weights and did cardio this morning. I feel great and I am excited. I did have a headache but Advil made it go away. I am drinking a little coffee and lots more water. It is 1:45pm now.
I think I will do great on this diet. I hate tiny meals and like to eat a big, reasonable meal and not worry if I have a slice of bread. I am a woman, turning 50 on April 27th. I am 5’8″ and 162 lbs. I gained this weight over two years. I want to weight 140. I started a 6 month personal training program two weeks ago so I am working out a lot.
How much do you think I can lose in a month eating reasonably? Also, can I make Bouillon cubes to satisfy hunger if I need to or is that considered eating?
Reasonably? 5 pounds or so.
If those cubes are super low in calories, it’s fine. The whole point of IF is to just get the majority of your calories in a few big meals. You can have a few snacks if you really get hungry but then you might not be able to eat as much for your main meals.
I use intermittent fasting from last year, and results are amazing, so much grateful for finding that
Good Day
I would like to know what you think about fasting everyday, as in having 1 meal a day with black coffee and water in between. I follow a banting lifestyle, for almost 7 months, and recently found I just do not get hungry. So I only eat once a day, and a very small meal. Could I be doing damage, or would this be okay?
Thank you for sharing your experience
Yes that is fine. Very similar to this – https://www.fitmole.org/eating-one-meal-a-day-diet/
Hi im 22 i weigh 163 im 4’11 nd i have beed IF for about 3 weeks now my start weight was 168 anf my goal weight is 125 my eating window is from 11 to 5 pm nd i fast for the rest of the time i eat two good size salads with chicken nd alot of veggies and i drink a galon of water a day is it okay that im eating abour 800 to 900 calories a day only?? And can u give me a estimate of when i could pisibly reach my goal weight thank u ..
no no, that’s way too few calories. I’d aim for about 1600 calories per day.
Hi! I am intending to try out leangains mixed with a couple of 24 hour fasts twice a week. I currently weigh 105 lbs, and I’m 5″2. How long until I get down to around 100lbs eating my 1400 calories?
Thanks!
Why do you want to want to keep losing weight, at that height, I wouldn’t recommend losing any more weight.
HI… I am about 5″9 and i weigh 143 lbs (65kg) not sure if thats correct, i have been on the warrior diet now my second week and only lost inches. My calorie intake is prob round 800-1000 as i get full quicker now on this diet. how long before i actually start losing kg.
Only inches? Inches is a lot.
Woah why are you eating so little. That’s dangerous. I would be getting a minimum of 1400 calories, assuming you’re a woman.
Hi I Kevin and I am doing the lean gains where I fast for 19 hours and eat for 5 hours and stay at about 1800 calories and drink 2 gallons a water a day and do hit workout 5 days a week I am 6/2 and 260 pounds how long do u think it would take me to get to 215 pounds I looking to be in thAt boat by July do u think it possible
– You’re doing a very dangerous thing, 1800 calories is way too low for your BW. You should be getting 2600 calories per day.
– Drinking that much water isn’t going to do anything magical in terms of weight loss
– No you’re cutting it too close. 45 pounds in 3 months is quite the feat, if you do do it you’ll risk muscle loss.
Hey, Keith. I’m desperate here. But not that desperate to basically kill myself so I wanna get your opinion. What do you think would be best for a 5’5 28 year old woman that weighs 240 pounds (see my problem?) I got into an accident and was bedridden for 3 months and basically during that time learned to eat all I wanted to because a. depression and b. couldn’t really move at all so I was just eating and sleeping in and no output to shake off the caleories, the medication was giving me these huge hunger pangs and my apettite basically quadrupled. I gained roughly 60 pounds in 1 months time can you believe it? Do you think what I’m doing right now, I only eat like an apple in the morning, apple and egg at lunch, drinking lots of water in between while working and once work is done, I basically then get my dinner. I think I’m only roughly eating around 900-1000 calories but I’m not exercising (ie. hip is still messing me up) but I make it a point to do normal walk for 10-20 minutes. Any insight would help. Thank you.
you’re eating way too few calories. You can do that for a few days, but after that you should go on a more moderate deficit. At your weight, at least 2000 calories per day would be ideal.
I started the 16:8 a little over a month ago. I am 6’4″, was 222 pounds at 18% BF. I am counting macros at 2000 cal a day. I have lost 10 lbs and down to 16% BF. My goal is 12% BF and the 16:8 diet is so damn easy. I lift weights fasted 4 days a week and the fat is melting while my strength is increasing!
It helped me a lot too, but now i am bulking with IF, and my waist is still slim, that’s beauty of intermittent fasting
Hi, I was wondering if I weigh 145 pounds and am also 5’1, how much pounds do you think I should aim to lose? I would like to lose body fat but also not look too skinny nor too fat, what should I do? I am willing to try the Eat stop Eat routine, how long do you think it will take me to get to a goal of at least 130 pounds?
Thanks so much for the shared experience by the way.
That amount, it will likely take you 8-12 weeks.
I want to try this, however, i do not know the basic rules of it.
Am i supposed to eat after a certain time?
How much am I supposed to eat?
Please read the article again.
With IF, in most situations you’re getting the same amount of calories as you normally would, the only difference is the total number of meals you eat. So if you used to get 2000 cals per day in 6 meals, you would now get 2000 cals per day in 1-3 meals.
Hi Keith. Im a 46 young female and most of my life ive been a size 10 @ 58kg. Then i became ill put on 30kg.
