Tournament evenings can add up: a couple of beers, a bag of chips and some pizza per match quickly outweigh the energy of jumping up when your team scores. Here’s the damage – and the cure.
How to use the World Cup Calorie Calculator
- Body weight
- Matches watched
- Beers (330 ml, ~140 kcal) per match
- Bags of chips (40 g, ~210 kcal) per match
- Bowls of popcorn (~150 kcal) per match
- Slices of pizza (~285 kcal) per match
- Activity to burn it off
Results update as you type, every field has its own unit menu, and everything is calculated in your browser.
How it works
Enter your weight, the number of matches and what you eat and drink per match, and choose an activity to burn off the surplus.
Inputs explained
| Field | What to enter |
|---|---|
| Body weight | Units: kg, lb |
| Matches watched | A number |
| Beers (330 ml, ~140 kcal) per match | A number |
| Bags of chips (40 g, ~210 kcal) per match | A number |
| Bowls of popcorn (~150 kcal) per match | A number |
| Slices of pizza (~285 kcal) per match | A number |
| Activity to burn it off | Choose one: Casual football (soccer), Running, 8 km/h, Cycling, moderate, Brisk walking … |
What each result means
- Energy intake = [Matches watched]×(140×[Beers (330 ml, ~140 kcal) per match] + 210×[Bags of chips (40 g, ~210 kcal) per match] + 150×[Bowls of popcorn (~150 kcal) per match] + 285×[Slices of pizza (~285 kcal) per match])
- Energy burned cheering = [Matches watched]×1.5×3.5×[Body weight]÷200×90
- Energy balance = [Energy intake] – [Energy burned cheering]
- Weight gain = ([Energy intake] – [Energy burned cheering])÷7700
- Time needed to burn it off = max(0, [Energy intake] – [Energy burned cheering])÷([Activity to burn it off]×3.5×[Body weight]÷200)÷60
Example values
How the main result changes when Body weight changes and everything else stays at the example values above:
| Body weight (kg) | Energy balance (kcal) |
|---|---|
| 40 | 6,759 |
| 60 | 6,428 |
| 80 | 6,097 |
| 100 | 5,766 |
| 120 | 5,436 |
| 160 | 4,774 |
Formula
Intake = matches × Σ(snack × kcal) · Burned cheering = 1.5 MET × 1.5 h per match · Weight change = (intake − burned) ÷ 7,700
Worked example
Inputs — Body weight: 80 kg; Matches watched: 7; Beers (330 ml, ~140 kcal) per match: 2; Bags of chips (40 g, ~210 kcal) per match: 1; Bowls of popcorn (~150 kcal) per match: 0; Slices of pizza (~285 kcal) per match: 2; Activity to burn it off: Casual football (soccer).
Results — Energy intake = 7,420 kcal; Energy burned cheering = 1,323 kcal; Energy balance = 6,097 kcal; Weight gain = 0.792 kg; Time needed to burn it off = 10 h 22 min.
Key terms
- Energy balance
- Calories in minus calories out.
