2000 Calorie Zigzag Calculator
See a 7-day calorie cycling schedule that averages 2,000 calories a day — higher days and lower days that still add up to the same weekly total.
Zigzag Calorie Calculator
Sets your weekly average: a calorie cut to lose (you choose the size below), maintenance to hold, or a 300 kcal/day surplus to gain.
A smaller deficit loses slower but is easier to sustain and better protects muscle — pick a gentler cut if you are already lean or training hard.
Used to estimate your maintenance calories — the energy you burn in a day — with the Mifflin-St Jeor equation, a standard peer-reviewed formula.
Range: 15–100 years
Range: 30–300 kg
Enter your height in centimeters (e.g., 170 cm)
Range: 100–250 cm
The schedule puts your highest day here — line it up with your hardest training or a social meal, and the rest of the week rotates to match. The weekly average doesn't change.

Quick Answer
How to Zigzag a 2,000-Calorie Day
A 2,000-calorie zigzag plan keeps the same weekly total as eating a flat 2,000 every day — 14,000 kcal across seven days — but varies the daily amount. Higher days land near 2,300 kcal, lower days near 1,700 kcal, and the week still averages exactly 2,000. The schedule above is filled in for you; read it straight off, or adjust the goal to cycle a different number.
The Week That Averages 2,000
A flat diet asks you to eat the same number every day; a zigzag spreads that same weekly budget unevenly. Start from a 2,000-calorie average and the calculator multiplies it across seven fixed factors — some days a little above, some a little below — that are chosen to add up to exactly seven. That single piece of arithmetic is the whole trick: because the factors sum to seven, seven days of them average back to one, so your week still lands on 2,000 a day. Two days come in around 2,300 and 2,200 calories, two around 1,800 and 1,700, and one sits on the 2,000 baseline. Nothing is added to or taken from the weekly total — 14,000 calories stays 14,000 — it is simply rearranged so the days are not all the same.
Line the Days Up With Your Week
The day labels in the schedule are only a template. The point of cycling is that you can put the higher days where you need the food and the lower days where you do not, as long as you keep the same count of high, low and baseline days so the average is preserved. Most people park the high days on their hardest training sessions or the evening they are eating out, and the low days on quiet rest days. If you would rather know whether 2,000 is the right average in the first place, the TDEE Calculator works out the calories your body burns, and the Calorie Deficit Calculator turns that into a fat-loss target you can then cycle here.
Same Total, Split Into Macros
Once you have the seven daily numbers, the next practical step is deciding what each day is made of. Protein is the figure to hold steady — keeping it high on the low days as well as the high ones is what protects muscle while the calories move around. To turn any of these daily totals into grams of protein, carbohydrate and fat, run the Macro Calculator on the number you want to plan, or build the whole cycle from scratch on the full Zigzag Calorie Calculator. These are general estimates for healthy adults, not medical advice.
The 7-day pattern uses multipliers that sum to exactly 7, so the weekly average always equals your target — this is arithmetic, not a metabolic effect. Maintenance estimates elsewhere on the site use the Mifflin-St Jeor equation (1990). Cycling does not change your weekly calorie total or your weekly deficit. Calorie cycling isn’t recommended under 19, in pregnancy or breastfeeding, or with a history of disordered eating — check with a clinician or registered dietitian first. Individual needs vary.
