No. The tools are designed to run locally in your browser unless clearly stated otherwise.

Question 3

Where do the snack calorie values come from?

Accepted Answer

Rounded average figures: a pizza slice at 285 kcal, a 330ml can of cola at 139 kcal, a standard chocolate bar at 260 kcal, a banana at 105 kcal, and a doughnut at 195 kcal. Real products vary.

Question 4

Should I use this for diet planning?

Accepted Answer

It's meant to make a calorie number easier to visualise, not as precise nutrition advice - see a dietitian or the BMI & Calorie Calculator for that.
