Time-blocking a day around an eating window

Put the eating window on the timeline first, then block work and training around it. That is the whole method. An eating window is a fixed appointment with yourself, and a day planner treats it the same way it treats a dentist visit: it goes in before anything else, and the rest of the day bends around it.

Most people do it the other way round. They fill the calendar with meetings, then try to squeeze meals into the gaps, and the window drifts an hour later every day until it stops being a window. Two fixed blocks solve that.

Step one: pick the window before you pick the day

An eating window is the stretch of hours you eat in. The rest is the fast. Sixteen hours fasting and eight hours eating is the common pattern, but the hours matter more than the ratio. A window from noon to eight suits someone who works late. A window from nine to five suits someone who trains in the morning and eats dinner early.

If you have not settled on the hours yet, do that first. The team's fasting app, Fasted, keeps a free fasting schedule tool that lays out the common patterns side by side, and a longer piece on which eating window works best for different working days. Decide there, then come back to the planner.

Step two: two anchor blocks

Open the day and add two blocks:

• First meal. Thirty to forty-five minutes. This is the start of the window.
• Last meal. Forty-five to sixty minutes. This is the close.

Make them recurring on weekdays. Give them a colour you use for nothing else. On a timeline view they read as two posts with the day strung between them, which is exactly how you want to see it.

Do not add a block for the fast itself. A twelve-hour block on a calendar hides everything under it. The fast is the space between the posts.

Step three: fit the work in

Now block the work. Three rules keep the window intact:

1. Deep work goes in the fasted hours. For most people the last two or three hours before the first meal are the clearest of the day. Put the hardest task there. Do not put a lunch meeting there.
2. Meetings that involve food go inside the window. A team lunch at half past twelve is fine if the window opens at noon. It is not fine if the window opens at two. Say no or move the window for that day, but decide it on the timeline, not at the table.
3. The last hour of the window is for eating, not for finishing something. If the last meal block keeps getting pushed by "one more email", shorten the work block before it instead.

Step four: training

Training and the eating window pull against each other, so place training on purpose.

• Training before the first meal works for walks, easy runs and light lifting. Put the session directly before the first-meal block, so the meal follows the work.
• Training inside the window suits anything hard. Put it two hours after the first meal and leave time to eat afterwards.
• Training after the last meal is the pattern to avoid, because it either ends the window early or pushes a meal past it.

If you want to plan the meals themselves around a session, the meal window planner on our sister site Fasted takes a window and a training time and lays the meals out. Copy its output into the planner as blocks and the day is done.

What a Tuesday looks like

| Time | Block | |---|---| | 06:30 | Walk, 30 minutes | | 07:00 to 09:30 | Deep work, fasted | | 09:30 to 11:30 | Calls | | 12:00 | First meal (window opens) | | 13:00 to 16:00 | Work | | 16:00 | Lift, 60 minutes | | 17:30 to 19:00 | Admin, email | | 19:15 | Last meal (window closes at 20:00) |

The two meal rows are the only ones that never move. Everything else is negotiable.

When it slips

The window slips for two reasons: the calendar filled up before you added the meals, or the hours were wrong for your life. The first is a habit and the fix is to add the two blocks every Sunday before the week arrives. The second is a planning mistake, and the fix is a different window, not more discipline.

A day planner will not make you fast. It will show you, before the day starts, whether the day you planned lets you.

FAQ

Should the eating window go on the calendar as an event?

Yes. Two events, one for the first meal and one for the last, anchor the whole day. Everything else gets scheduled around them, which is the point.

What if a meeting lands in the middle of my first meal?

Move the meal, not the window. Shift the first meal 30 to 60 minutes and keep the closing time the same. If it happens every week, the window is set at the wrong hour.

Do I need a fasting app and a planner?

They do different jobs. The planner holds the day. A fasting timer counts the hours between meals and tells you where you are in the fast. Most people who fast use both.
