Ever since you started working from home, you find yourself mindlessly snacking all day.
You get sleepy after lunch, and your afternoon work goes nowhere.
Does that sound familiar?
The truth is, working from home is an outstanding match for fasting.
At the office, there’s the habit of “everyone going to lunch together,” which makes fasting hard, but at home you can control the timing of your meals yourself.
In this article, I’ll show you how to design your day by combining fasting with a work schedule, so you can maximize your focus while also losing body fat.

Why Do We Overeat While Working from Home?
The Temptation of “the Kitchen Being Right There”
The biggest difference between working at an office and working from home is how easy it is to get to food.
At the office, eating something meant walking to a vending machine or a convenience store.
But at home, the kitchen is just a quick stand-up away.
Open the fridge, and food jumps right into view.
This “zero-distance” environment multiplies unconscious snacking many times over.
“I’m Tired of Working” Leads Straight to Appetite
When you work from home, the line between work and your private life tends to blur.
Craving sweets and carbs when your brain is tired is a physiological reaction, but what happens when that’s happening right next to the kitchen…?
The pattern of “taking a little break = eating” becomes ingrained.
I myself gained 2 kg (about 4.4 lb) in the first three months after switching to working from home.
When I counted how many times I stood in front of the fridge, I was stunned to realize it was more than 10 times a day.
No Commute Means Less Movement
Something people often overlook about working from home is the drop in activity that comes from no longer commuting or moving around the office.
Walking to the station, climbing stairs, heading to a meeting room.
These “little bits of movement” make up a surprisingly large share of the energy you burn each day.
The technical term for this is “NEAT,” which refers to the energy you use in everyday movement other than exercise.
To put it another way, it’s like a bank account that used to have a little money withdrawn every day, and suddenly the withdrawals stop.
If what’s going out decreases but what’s coming in (how much you eat) stays the same, the balance, in other words your body fat, keeps growing.
A Disrupted Daily Rhythm and “Eating While Doing Something Else”
At home, it’s easy for your wake-up time and mealtimes to become all over the place, isn’t it?
When your body clock gets thrown off, the rhythm that signals hunger also breaks down, making it more likely that you’ll “want to eat something even though you’re not hungry.”
On top of that, many people probably eat lunch at their desk while looking at their computer.
When you eat while distracted by a screen, your brain has trouble recording that you “ate,” making it harder to feel satisfied.
It’s similar to the feeling of eating popcorn during a movie and suddenly finding the bucket empty.
In other words, overeating while working from home isn’t caused by weak willpower; your environment and daily rhythm are major causes.
- “Zero distance” to the kitchen increases how often you snack
- Work fatigue easily becomes linked to appetite
- If you don’t set “eating hours,” you end up eating any time
- No commute means less everyday activity
- A disrupted daily rhythm and “eating while doing something else” make it hard to feel satisfied
The Basic Design of Fasting × Working from Home
The Best Fasting Schedules for Remote Workers
For remote workers, the following three patterns are easy to put into practice.
| Pattern | Fasting hours | Eating window | Best for |
|---|---|---|---|
| Morning focus plan | 20:00 to 12:00 the next day | 12:00–20:00 | People who want to focus in the morning and are fine without breakfast |
| Midday-to-night focus plan | 22:00 to 14:00 the next day | 14:00–22:00 | People who don’t mind being hungry from morning to midday and eat on the later side at night |
| 5-day-a-week fasting plan | Fast on weekdays only (20:00 to 12:00 the next day) | 12:00–20:00 | People who want to eat normally with their family on weekends |
How to Choose the Plan That Suits You
A good way to decide among the three plans is by “the time of day you most want to focus” and “your family’s schedule.”
- If much of your morning is spent on brain-heavy work like writing proposals or programming, the morning focus plan is a good fit.
- If your mornings are full of meetings and your real work happens from the afternoon into the evening, the midday-to-night focus plan will likely be easier to stick with.
- If you value eating with your family on weekends, doing the 5-day-a-week plan and fasting only on weekdays is a perfectly good choice.
What matters is choosing “a plan you can keep up” rather than “the perfect plan.”
It’s just like clothes: no matter how well-reviewed something is, you won’t keep wearing it if it doesn’t fit.
Start by choosing one and trying it for a week, and if it’s too tough, feel free to switch to a different plan.
The Link Between Fasting and Focus
During a fast (from about 4 to 6 hours after eating), your blood sugar stabilizes and ketone bodies start being used as fuel for your brain.
Because ketone bodies reach the brain more efficiently than glucose, “post-meal drowsiness” goes away, and it becomes easier to sustain focus for long periods.
Think of ketone bodies as a fuel made in the liver when body fat is broken down.
If we compare it to a car, it’s like a “reserve tank” that kicks in when you’re running low on gas.
Post-meal drowsiness tends to happen when a meal makes your blood sugar spike and then drop sharply.
During a fast, your blood sugar rises and falls less, so you’re less likely to get roller-coaster-like “waves of sleepiness.”
I also explain how to maximize focus with fasting in detail in this article.
- Post-meal blood sugar spikes → a cause of drowsiness and poor focus
- During a fast, ketone bodies fuel the brain → no drowsiness, focus maintained
- The hungry hours of the morning are the most productive
The Golden Schedule Template for Fasting × Working from Home
A Daily Schedule for the Morning Focus Plan
The plan I recommend most is the “morning focus plan.”
You use the hungry hours from 7 a.m. to noon to focus on and finish your most important work.
| Time | Activity | Fasting status | Key point |
|---|---|---|---|
| 7:00–8:00 | Wake up, light stretching, plain hot water | Fasting | Wake your body up and hydrate |
| 8:00–10:00 | Most important task (focused work) | Fasting (peak focus) | Hunger = high-focus hours. Put creative work here |
| 10:00–10:15 | Coffee or black tea break | Fasting (OK to continue) | An extra focus boost from caffeine |
| 10:15–12:00 | Email and meetings | Fasting | Do routine work during this time |
| 12:00–13:00 | Lunch (breaking the fast) | Eating window begins | Start with easy-to-digest foods |
| 13:00–15:00 | Light tasks, preparing documents | After eating | Shift to lighter work after eating |
| 15:00–15:15 | Snack (nuts, cheese, etc.) | Within eating window | Choose low-GI foods to avoid blood sugar spikes |
| 15:15–17:30 | Afternoon focused work | After eating | A productive part of the afternoon |
| 18:00–19:00 | Dinner | Eating window | Finish eating by 8 p.m. |
| 20:00 onward | Fast begins | Fasting | Water and tea only from here on |
Tips for Fitting the Schedule to Your Own Work
The template is only a “framework,” so adjust it to fit your own work.
The key is to split your work into “brain work” and “hands-on work.”
Brain work means tasks where you think and make decisions, such as planning, writing, and analysis.
Hands-on work means routine tasks like replying to emails, data entry, and filing expenses.
If you put brain work in the morning while you’re fasting and hands-on work in the post-meal 1 p.m. to 3 p.m. slot, your schedule will likely run more smoothly.
To compare it to cooking, it’s like making the dishes that need careful heat control while you can still concentrate, and doing all the washing up together afterward.
If you can’t choose your own meeting times, even just shifting your brain work into the hours without meetings will likely make a difference.
Make Your Post-Fast Lunch a “Meal That Won’t Make You Sleepy”
On the morning focus plan, lunch at noon is your first meal after the fast.
What’s in this one meal will likely make a big difference in how well your afternoon work goes.
I recommend a meal centered on vegetables and protein, such as salad, hearty miso soup, grilled fish, eggs, and tofu.
Meals that fill you up with carbs alone, like donburi (Japanese rice bowls), ramen, or sweet buns, tend to bring on drowsiness after eating, so go easy on them.
If you do eat carbs, choosing slowly absorbed options like brown rice or whole-wheat bread is a safe bet.
An Answer to “I’m Worried I Won’t Be Able to Work While Fasting”
Many people feel that “there’s no way I can work on an empty stomach.”
In fact, the first 1 to 2 weeks until you get used to fasting are the hardest part, and once you get past that, hunger stops getting in the way.
For the first few days, I recommend starting with a 12-hour fast and gradually extending it to 16 hours.
For how to make fasting a habit in 21 days, see this article.
Setting Up Your Environment to Support Fasting While Working from Home
Design It So “Out of Sight → Not Eaten”
Changing your environment is the most effective way to boost your chances of fasting success.
The key is to build a system that “doesn’t rely on willpower” first.
- Don’t keep snacks or food on your desk (keep them away from the kitchen)
- Make a habit of not opening the fridge while fasting (for example, put a note on the door)
- Always keep “fasting drinks” (tea, water, coffee) next to your desk
- When you feel hungry, switch what you’re working on (routine work → a walk → back to focused work)
The Ultimate Combo: Pomodoro × Fasting
Combining the Pomodoro Technique (25 minutes of work + a 5-minute break) with fasting makes it easier to keep your waves of focus steady.
By building in a routine of “drinking a cup of tea” at every break, you can neutralize your appetite with fluids while keeping your work rhythm going.
For ways to deal with stress eating while fasting, also take a look at this article.
Create “Breaks” at the Start and End of Your Workday
When you work from home, switching between work mode and relaxation mode gets harder.
That’s why I recommend deciding on “signals” for starting and ending your workday.
For example, it can be as simple as drinking a cup of plain hot water before opening your laptop, or closing your laptop and taking a 5-minute walk when you finish work.
Just like a stage curtain rising and falling, having a clear break makes it easier for your brain to recognize “this is work time.”
When those boundaries are clear, mindless eating along the lines of “I’m tired, so I’ll grab a little something” will likely decrease too.
Keeping your workspace as far from the kitchen as possible also helps.
If you don’t have much space, simple tweaks like sitting with your back to the kitchen or putting food away in the cupboard are plenty.
Tips If You Live with Family
When you live with family, they’ll eat normally even while you’re fasting.
In that case, letting your family know your fasting hours cuts down on unnecessary temptation.
If you just mention, “I don’t eat until noon,” you’ll probably be offered snacks less often.
Asking for their cooperation, like having them keep their snacks somewhere out of your sight, is another option.
If you include the evening in your eating window so you can have dinner with your family, it becomes easier to balance fasting with family time.
Make Sleep Work for You
One thing you can’t overlook when it comes to keeping up fasting is sleep.
It has been reported that lack of sleep tends to increase the hormone that boosts appetite (ghrelin) and decrease the hormone that signals fullness (leptin).
This is probably why you crave sweets on exactly the days you’re short on sleep.
Since there’s no commute, working from home is also an environment where it’s easy to stay up late.
Keeping your wake-up time and bedtime as consistent as possible also helps stabilize your fasting rhythm.
Things to Watch Out for When Fasting While Working from Home
Watch Out for Dehydration
While fasting, you also lose the water you used to get from food.
Food contains water too, so if you only drink your usual amount, you could become dehydrated without realizing it.
When you work for long hours in an air-conditioned room, it’s also harder to notice that you’re thirsty.
If you get a headache or feel sluggish, suspect dehydration before hunger.
Coffee makes you lose water through urine more easily, so make sure to drink water or tea in addition to coffee.
Keep a drink on your desk and get into the habit of taking a sip at least once an hour.
Don’t Binge During Your Eating Window
If you eat a lot all at once after a fast because you’re hungry, your blood sugar shoots up, which leads to afternoon drowsiness.
After a period of hunger, your body is like a dry sponge soaking up water all at once.
Eating vegetables, protein, and soup first and saving carbs for last will likely make it easier to keep your blood sugar from spiking.
Within your eating window, it’s also important to get plenty of protein and vegetables so your nutrition doesn’t become unbalanced.
People Who Should Avoid Fasting
If any of the following apply to you, don’t start fasting on your own judgment; consult a doctor first.
- People using medication or insulin for conditions such as diabetes
- People who are pregnant or breastfeeding
- People who have experienced an eating disorder
- People with a chronic illness who are under treatment
Also, if you experience dizziness, a strong pounding heart, or shaky hands while fasting, don’t push yourself; eat something.
Fasting isn’t an endurance contest; it’s one tool for getting your health and your work rhythm in order.
Be Careful About Sitting All Day
When you work from home, do you ever realize you’ve been sitting in the same position for hours?
Sitting for long stretches tends to slow your circulation and can cause sluggishness and stiff shoulders.
When your head starts to feel foggy during a fast, try standing up and moving your body first.
Stretching during your 5-minute Pomodoro breaks or standing up only while you’re on the phone are also good ideas.
Just moving your body a little will likely shift your mood and make it easier to take your mind off hunger.
Frequently Asked Questions About Fasting While Working from Home
You may notice some dip for the first 1 to 2 weeks until you get used to it.
If you start with a 12-hour fast and gradually extend it to 16 hours, you should be able to adapt without strain.
Once you’re used to it, your morning focus clearly improves.
Drinking a glass of water or tea before the meeting eases hunger.
Chewing gum is also effective (sugar-free gum won’t affect your fast).
Yes, it can make a big difference.
By “starting with low-GI foods” at your first meal after the fast, you can prevent blood sugar spikes and keep post-meal drowsiness to a minimum.
The most effective approach is to set a rule: “Don’t eat anything outside the eating window.”
Simply being aware that “this is a no-eating time” greatly reduces the urge to snack.
I recommend making it a rule to “finish dinner 3 hours before bed,” then fasting from that point until lunch the next day.
Your sleeping hours also count toward your fasting time, so the actual time you spend hungry is shorter.

The First 2 Weeks: Start with “Just 12 Hours for Now”
Rather than aiming for a 16-hour fast right away, start with 12 hours, “from 10 p.m. to 10 a.m. the next day”.
Most people spend 8 of those hours asleep, so you only have to hold out for the 4 hours before bed and after waking up to make it.
Once you’ve kept it up for 2 weeks, shift the end of your fast to 11 a.m., then noon, and move the time you finish dinner earlier, to around 8 p.m., gradually working toward 16 hours.
3 Steps to “Systematize” Fasting × Your Schedule
- Fix your fasting window: fasting during the same hours every day keeps your body’s rhythm in order
- Plan your schedule the day before: write down the next day’s schedule and fasting hours in your planner or phone
- Set your focused work during fasting hours: put your most important work in the hungry hours (the morning)
These 3 steps are like laying down “work tracks” inside your home.
Once the tracks are set, you don’t have to wonder which way to go every morning, and you can put your energy into the work itself.
Even if some days don’t go well, it’s no problem as long as you get back on the same tracks the next day.
You can review the basics of 16-hour fasting all in one place in this complete guide.
