Common intermittent fasting mistakes (and how to avoid them)
Intermittent fasting is a simple rule — eat in the window, not outside it. But small mistakes turn it into days of wasted effort. These are the most common ones, with fixes.

Drinking calories in the fasting window
Latte, juice, smoothies — liquids that carry energy break a fast just as surely as a meal. In the fasting window, drink water, black coffee or tea without sugar.
If the point is only timing, a "wet fast" is no big deal — but if the goal is a deficit, every latte counts. The diary makes the difference visible.
Overeating inside the eating window
The window is not a license. If you eat the same amount in 8 hours that you used to eat in 16, nothing changes — a deficit comes from calories, not from the clock.
Fasting is a tool for holding a deficit, not the deficit itself. Log inside the window too — photo and correction, as always.
Starting too aggressively
20:4 from day one is the classic road to burnout: hunger, headaches, quitting within a week. Start at 12:12 or 14:10 and move on only when the current window feels easy.
The best fasting schedule is the one you can hold for months — not the one that sounds the most effective.
Forgetting protein and fiber
Inside a short window, fullness is everything. Protein-rich foods and fiber keep hunger away longer — a bread-and-sweets diet makes the window a torture.
You can see protein per meal in the diary; if it stays small inside the window, adjust the distribution.
Forgetting sleep and steps
Bad sleep and little movement make a fasting day harder: hunger signals run stronger and the evening runs longer. Fasting does not work in a vacuum — sleep, steps and food move together.
All three in one diary show the pattern: bad night, fewer steps, evening snacking.
Who fasting is NOT for
Fasting is not for everyone: pregnancy, a history of eating disorders, diabetes medication and some medical conditions require talking to a doctor first. If you are unsure, ask a professional — do not try to out-fast a health problem.
TempoLife is a tool, not a medical device: it does not diagnose or give medical advice.
Frequently asked questions
Does coffee break a fast?
Black coffee practically does not — the problem is milk and sugar. A latte carries energy, and that breaks the fast.
I broke my streak — do I start over?
A streak is a tool, not the goal. Continue from the next day. Patterns emerge over weeks, not from single days.
TempoLife is a diary, not a medical device — fasting does not replace a doctor's advice and it is not for everyone.
