Beginners guide to 14:10 intermittent fasting
14:10 intermittent fasting could help you lose weight.
It could improve your health.
It could bring both freedom and discipline to your eating habits.
All without the long, restrictive fasts of 16:8, 18:6, or 20:4.
It’s quite possibly the perfect way to get started.
Could 14:10 intermittent fasting be the happy medium you’ve been looking for?
What is 14:10 intermittent fasting?
Following the 14:10 intermittent fasting schedule splits your day into two windows: a 10-hour window when you eat and a 14-hour window when you fast.
No rules about what you can and can’t eat.
No rules about how long you need to follow this schedule.
No rules of any kind except to follow that 14:10 split.
As such, when you follow an intermittent fasting schedule, you get way more freedom than with traditional diets. Because intermittent fasting isn’t actually a diet — it’s simply a way of structuring your eating that could bring a ton of health benefits.
And 14:10 intermittent fasting is an easy, entry-level option — perfect for getting started.
How does 14:10 intermittent fasting work?
Going for 14 hours without food might sound pretty tough.
But bear in mind that you’ll most likely be asleep for a good chunk of those hours, and actually, eating on a 14:10 intermittent fasting schedule won’t feel all that different from what you’re doing now.
You just gotta pull in the edges. Take breakfast, lunch, and dinner, and squash them a little closer together. It’s completely up to you where you place your 10-hour eating window in your day, and you can change it to suit you if your schedule shifts around.
For instance, maybe during the work week, 10 AM till 8 PM works great. But on the weekend, you like to have breakfast later and hit some tacos with friends for dinner, so 11 AM till 9 PM is a better fit.
So long as you hit that 14-hour fast, it’s all good.
What to eat on a 14:10 intermittent fasting schedule
What to eat during 14:10 intermittent fasting is completely up to you. That can feel both freeing … and terrifying. Knowing the best food choices to support your goals is no small thing.
We’re here to give you some ideas.
Whether you’re looking to lose weight or optimize your health, if your meal plan contains predominantly foods like this:
- lean protein
- whole grains
- veggies and fruits
- healthy fats
- calcium-rich foods
And doesn’t contain too many foods like this:
- ultra-processed foods
- refined carbohydrates
- unhealthy fats
You’ll get results.
We can help you put together a meal plan that’s both full of foods you like and supportive of your goals. Go check out our intermittent fasting meal planning guide for everything you need to know and the next steps you can take.
There are no calorie counts to nail or macros to hit with 14:10. Instead, we’d encourage you to listen to your body and follow your appetite cues. In other words, during your eating window, eat when you’re hungry and stop when you’re full. This does take practice, no doubt. But it’s a skill well worth getting good at.
The foods above will help. Nutrient-dense foods curb hunger, keep you fuller for longer, and don’t trigger cravings. When you want to work in tandem with your appetite and eat what your body needs (as opposed to, say, eating with your emotions), lean proteins, veggies, whole grains, and healthy fats are a sure bet.
Once you’re out of your eating window and into your fasting period, you’re in the calorie-free zone. Here, stick to water plus unsweetened tea / coffee without milk.

14:10 intermittent fasting and weight loss
14:10 intermittent fasting can lead to good results for those looking for weight loss, as studies show.[1,2]
Some studies have found that intermittent fasting resulted in participants losing between 0.8% and 13% of their starting body weight.[1]
As with all lifestyle changes, the impact of intermittent fasting on health and weight will depend on many factors, like age, activity levels, dietary choices, and so on. But many people have seen success with intermittent fasting on a 14:10 split. That success is likely down to a couple of key intermittent fasting-related happenings.
The first is that shrinking your eating window naturally creates a calorie deficit. When you eat less than you burn, you lose weight.
The second is that fasting puts the body into ketosis. When you don’t eat for a prolonged period, you don’t give your body any glucose with which to fuel your activities. So, it turns to your glycogen stores and, when they’re used up, to your fat stores. This is ketosis, the metabolic shift caused by intermittent fasting that helps you lose body fat.
14:10 intermittent fasting schedule results
“When I started [intermittent fasting] last fall, I had been trying to get off some medications. Trying to keep up with what to eat & how often to exercise started discouraging me. I began to wonder if I could ever lose the weight and stop taking medications I didn’t want to take.
Then, I discovered [intermittent fasting].
I started seeing losses and haven’t looked back since. I started out on a 14:10 [schedule] and now do 17:7.”
This is a great example of how 14-hour intermittent fasting can both generate results and open up the world of longer fasts (should you want it to!).

Health benefits of 14:10 intermittent fasting
14:10 intermittent fasting hasn’t been studied as much as other intermittent fasting schedules.
That said, one study, in which people with metabolic syndrome followed a 14:10 intermittent fasting schedule for 12 weeks showed some promising health benefits.[3]
Reduced cholesterol levels
Participants’ total and LDL cholesterol levels dropped.
Lower blood pressure
Decreases in systolic and diastolic blood pressure were observed.
Decreased body weight and body fat
There were significant reductions in body weight, and waist circumference decreased.
Improved blood sugar
Participants who had high HbA1c and fasting glucose levels experienced a drop in their HbA1c.
Lower risk of metabolic syndrome
Taken together, these effects lower the risk of metabolic syndrome, as well as other health conditions, like heart disease.
Health risks of 14:10 intermittent fasting
As an intermittent fasting schedule with a longer eating window, 14:10 hasn’t got as many risks as some others, though there are still some to be aware of.
Weight gain
One of the temptations with intermittent fasting is to get sucked into the “eat whatever you want!” freedom of it. With that approach, it’s really easy to gain weight.
What you eat is completely your call. You’re the boss here. Just be mindful of whether the food choices you’re making align with the goals that are important to you.
Hunger and crankiness
Initially, you may feel pretty hungry and cranky, especially if you’re a habitual evening snacker and your fasting period cuts that off. Drink lots of water, and make friends with new kinds of herbal teas to give you something flavorful for the evenings. You will adjust.
Dehydration
Food provides a significant proportion of your daily fluid intake, so although it might seem weird, you can actually get dehydrated through fasting. Again, drink lots of water, and be sure to schedule a bunch of vegetables and fruits into your meal plan.
Is 14:10 intermittent fasting safe?
14:10 is considered one of the easiest and safest fasting methods, so it’s on the table for most people to try.
That said, there are some people who should avoid fasting, no matter how gentle the schedule seems. Don’t try intermittent fasting — unless you have your doctor’s full blessing and support — if you:
- are extremely active
- are under 18 or 80 years or older
- have (or are at risk of having) an eating disorder or have a history of one
- have a BMI <18.5
- take prescription medications
- have a medical condition
- are pregnant, breastfeeding, or trying to conceive
Pros and cons of 14:10 intermittent fasting
| Pros | Cons |
| Shorter (mostly overnight) fasting periods | You might not reach ketosis |
| You write the meal plan | You write the meal plan! |
| You could lose weight | Results might be slow |
| It could benefit your health | It might feel hard (at first) |
Pros
On a 14:10 intermittent fasting schedule, the shorter fasts are easier (relatively speaking), and most of your fasting will take place overnight.
You get to call the shots on what you eat and when, and your weight may decrease while your metabolic health increases.
Cons
With a shorter fast, it’s not a done deal that you will reach ketosis, or if you do, you won’t spend as much time there as with longer fasts. So, results may be slower than you had hoped.
Any new approach to eating will feel hard at first, and you’ll need to adjust to new habits, like meal planning, to really feel the benefits of this method.

5 pro tips for 14:10 intermittent fasting
Let us help you get the most from 14:10 with some pro tips.
- Start slowly
You don’t have to start with 14 hours. You could start with 12. Or by simply adding one hour to your existing overnight fast.
Practice makes progress, so don’t be afraid of starting out wherever you feel most comfortable.
- Exercise for better results
If you want speedier results, throw some exercise into the mix. Whether it’s walking, steady-state cardio, weight lifting, or yoga — whatever floats your boat will bring some extra power to your ability to reach your goals.
- Listen to your body
Notice how you feel when you practice 14:10.
Do you feel full of energy and clearheaded? Or do you feel kind of slumpy and fogged up? That will give you some guidance on whether 14:10 is working for you.
- Become a ninja at meal prep
Meal planning is key to success with intermittent fasting. Hand in hand with that is meal prep.
Making sure you have the food you need when you need it is a HUGE factor in eating the food you planned!
So whether you need to find time for regular grocery shopping, get comfy with chopping veggies, or break out the crock pot that’s been languishing in the back of the cupboard for years, put “get good at meal prep” on your to-do list.
- Practice wiping the slate clean
There will be days where your hunger will have you fast-breaking too early, you snuggle down with Netflix rather than knocking out a workout, or your meal prep hits the wall.
No problem. Simply wipe the slate clean and keep going. Days like that are part for the course. In the meanwhile, take a look at our guide on how not to feel hungry when fasting.
