Introduction to intermittent fasting
Intermittent fasting, sometimes called time restricted eating time restricted eating (TRE), is an eating method that alternates between fasting windows and eating periods. Unlike strict diets, it’s not about cutting out specific foods. It’s about when you eat.
Studies show intermittent fasting schedules can support weight management,[1] insulin sensitivity insulin sensitivity ,[2] and heart health,[3] and improve some aspects of metabolism metabolism .[4] People often notice benefits like reduced blood sugar fluctuations [5] and even improvements in hormone levels.[6]
Intermittent fasting can take many forms — from alternate day fasting to only one meal a day — but one beginner-friendly approach is 14:10 intermittent fasting, a gentle schedule that balances results with flexibility.
What is 14:10 intermittent fasting?
Following the 14:10 intermittent fasting schedule splits your day into two windows:
-
a 10-hour window, during which you eat and
-
a 14-hour window, during which you fast.
When you follow an intermittent fasting schedule, you get more freedom than with traditional diets. There are no rules about what you can and can’t eat. Because intermittent fasting isn’t a diet — it’s simply a way of structuring your eating that can have many health benefits.
Going for 14 hours without food might sound tough. But you’ll most likely be asleep for a good chunk of that time. To be honest, eating on a 14:10 intermittent fasting schedule probably won’t feel all that different from what you’re doing now.
How does 14:10 intermittent fasting work?
If you’re exploring 14:10 intermittent fasting, you’re likely wondering what’s actually going on behind the scenes and how it might feel. Let’s explore that.
During your 10-hour eating window, your body uses glucose from food as its main energy source. Insulin levels rise, helping move that glucose into cells. Any extra energy you don’t immediately use is stored as glycogen or, if those stores are full, as fat. This is a normal, healthy metabolic process.
Once you move into the 14-hour fasting window, insulin levels gradually fall. After roughly 10–14 hours without food, your body begins shifting away from glucose and starts tapping into stored fat for fuel. This process releases fatty acids and small amounts of ketones into the bloodstream, signaling the beginning of a metabolic shift.
Because 14:10 is a relatively short fast, this shift tends to be gentler than with longer intermittent fasting schedules. Still, some people notice temporary side effects in the early days, such as hunger, mild fatigue, headaches, or difficulty concentrating. These usually ease as your body adapts to your new eating rhythm.
It’s also worth knowing that a restricted eating window can occasionally disrupt your social plans.
But, for most people, once that initial phase passes — and with little flexibility and forward planning — energy levels improve, focus sharpens, and mood steadies, making the schedule feel far more natural and easier to live with than you might expect.
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. Making the best food choices for your goals isn’t easy. We’re here to give you some ideas.
If you’re looking to lose weight or optimize your health, your meal plan should contain lots of:
-
lean protein
-
whole grains
-
veggies and fruits
-
healthy fats
-
calcium-rich foods
Ideally, you’ll eat fewer:
-
ultra-processed foods
-
refined carbohydrates
-
unhealthy fats
Check out our intermittent fasting meal planning guide to help you put together a meal plan that’s both full of foods you like and supportive of your goals.
There’s no calorie or macro counting with 14:10. During your eating window, you simply listen to your body and follow your appetite cues. In other words, eat when you’re hungry and stop when you’re full. This does take practice. But it’s a skill well worth improving.
Nutrient-dense foods will help. They curb hunger, keep you fuller for longer, and don’t trigger cravings. When you want to eat what your body needs (as opposed to eating with your emotions), lean proteins, veggies, whole grains, and healthy fats are a sure bet.
Once you’re into your fasting period, stick to calorie-free foods and beverages, like water, unsweetened tea without milk, black coffee, etc.

14:10 intermittent fasting and weight loss
The impact of intermittent fasting on health and weight will depend on many factors, like age, activity levels, and your dietary choices. But many people have seen weight loss success with intermittent fasting on a 14:10 split,[7,8] with some studies finding fasting helped participants lose between 0.8% and 13% of their body weight.[7]
That success is the result of a couple of key things.
Firstly, shrinking your eating window naturally creates a caloric deficit. When you eat less than you burn, you lose weight.
Secondly, fasting puts the body into ketosis ketosis , the metabolic shift caused by intermittent fasting that helps you lose body fat. When you don’t eat for a prolonged period, you don’t give your body any glucose to fuel your activities. Once your stored glycogen glycogen is used up, your body turns to your fat stores.
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 lead to 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.
But one study found that people with metabolic syndrome metabolic syndrome who followed a 14:10 intermittent fasting schedule for 12 weeks experienced several promising health benefits.[9]
Reduced cholesterol levels
Participants’ total and LDL cholesterol cholesterol levels dropped.
Lower blood pressure
Decreases in systolic and diastolic blood pressure 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 doesn’t have as many risks — but it does still have some.
Weight gain
One of the temptations with intermittent fasting is just to eat whatever you want. That approach makes it really easy to gain weight. Be mindful of how the food choices you’re making align with your goals.
Hunger and crankiness
Initially, you may feel pretty hungry and cranky, especially if you’re an evening snacker and your fasting period cuts that off. Drink lots of water, try new kinds of herbal teas to give you something flavorful for the evenings, and practice hobbies to keep you occupied. You’ll adjust, we promise.
Dehydration
Food provides a big proportion of your daily fluid intake, so, if you’re eating a lot less in your eating window and not focusing on your hydration, you can get dehydrated through fasting. Again, drink lots of water, and be sure to add plenty of vegetables and fruits into your meal plan.
Is 14:10 intermittent fasting safe?
14:10 is considered one of the 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 without 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 | Writing meal plans isn’t easy |
| 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 call the shots on what and when you eat, and your weight may decrease while your metabolic health increases.
Cons
With a shorter fast, you might not reach ketosis, or if you do, you might not spend as much time there as with longer fasts. So, results may be slower than you 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.

Getting started with 14:10 intermittent fasting
Get started with 14:10 intermittent fasting with these top 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 start out wherever you feel most comfortable.
Choose your fasting window
You get to decide where to put your 10-hour eating window in your day. You can always change it to suit you if your schedule shifts around. So maybe during the work week, 10 AM till 8 PM works best. But, on the weekend, 11 AM till 9 PM is better. So long as you hit that 14-hour fast, it’s all good.
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 slumpy and fogged up? That will give you some guidance on how 14:10 is working for you.
Get good at meal prep
Meal planning is key to success with intermittent fasting. Hand in hand with that is meal prep — i.e., making sure you have food ready to go when you need it. 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 hunger will make you break your fast too early, or your meal prep hits the skids. No problem. Wipe the slate clean and keep going. Days like that are par for the course.

Exercise for better results
If you want speedier results, add some exercise into the mix. Whether it’s walking, steady-state cardio, weight lifting, or yoga, all movement will bring extra power to your ability to reach your goals.
FAQs
How long does it take to see results from 14:10 intermittent fasting?
Most people start to notice changes in weight, fat mass, energy levels, and other health benefits within a few weeks of following a 14:10 intermittent fasting schedule. Results vary depending on your diet, exercise, meal plan, and overall calorie intake, as well as age, activity level, and health status.
Is 14:10 fasting as good as 16:8?
Both fasting methods provide many of the same intermittent fasting benefits when combined with healthy eating and regular movement, such as supporting weight loss, insulin sensitivity, blood pressure, gut health, muscle mass, and heart health. Because 16:8 includes a longer fasting time, results like improved metabolism or reduced fat mass may come faster. That said, 14:10 is gentler, easier to fit into daily life, and often more sustainable for most people who want better health without extreme fasting.
What happens to your body when you fast for 14 hours?
During the 14-hour fasting window, your body switches from using glucose from your normal diet to burning glycogen and fat stores for energy. This metabolic switch can help reduce insulin resistance, improve insulin sensitivity, and support overall health. You may notice mild side effects in the first few days or weeks, such as hunger, fatigue, or difficulty concentrating, but these usually pass as your body adapts.
Does 14-hour fasting help with weight loss?
Following 14:10 intermittent fasting can help you lose weight, reduce fat mass, and improve energy intake management. Limiting calories during fasting time, while eating a healthy diet during your eating window, supports weight management, muscle mass, and metabolic health. Limiting processed foods and focusing on healthy foods maximizes the benefits and reduces the risk of weight gain.
What can I eat on a 14:10 fast?
During fasting time, stick to water, black coffee, and unsweetened teas. During your eating periods, you can enjoy a normal diet, but a balanced eating plan rich in healthy foods, lean protein, whole grains, vegetables, fruits, and healthy fats will help you get the most intermittent fasting benefits. Minimizing processed foods and highly refined carbohydrates supports gut health, heart health, and blood sugar control.
How does 14:10 compare to Eat Stop Eat?
14:10 intermittent fasting is much gentler than Eat Stop Eat, which involves two 24-hour fasts each week, and other approaches like alternate day fasting, which are more extreme and harder to maintain. 14:10 and other time restricted eating methods provide similar health benefits, are easier to follow consistently, and carry fewer risks for disordered eating or eating disorders.
Does 14:10 intermittent fasting slow metabolism?
The evidence generally suggests that intermittent fasting does not slow metabolism. In fact, many people see improvements in insulin sensitivity, fat mass reduction, and overall health. Maintaining a healthy diet, regular three meals or structured eating periods, and exercise can help preserve muscle mass and support good health. More research continues on long-term effects, but current studies suggest 14:10 is safe for most adults.
