How to find your true maintenance calories in 14 days
Online calorie formulas only guess your number. The true way is a 14-day test: eat your normal food, weigh daily, and let the weekly average tell you the calories that hold your weight flat.
You typed your height and weight into a free website. It handed you a neat number. You felt sure. But is that really what your body burns each day? A formula cannot see your rotis, your chai, your long office hours, or your sleepless nights. Only your own body knows the true number. This guide shows a 14-day test to find it.
An online TDEE calculator gives you your true maintenance calories.

A calculator uses a maths formula. It knows your age, height, weight, and sex. That is all. It cannot see your real food, your daily steps, or your sleep. Scientists who study body weight say energy needs change as your body changes, and a single sum cannot keep up. Their number is a starting guess, often a few hundred calories off either way. Your real number can only come from watching your own body.
The 14-day test that tells the truth
Here is the honest method. For 14 days, eat your normal food. Log every meal in Burnie. Weigh yourself each morning after the bathroom, before chai or water. Write the weight down. At the end of each week, average all seven days. Why 14 days? Because your weight swings every day from water, salt, and food inside you. A normal adult's weight can move about 2 to 3 kilograms in a single day. That is huge noise. Scientists also note people's energy intake swings 20 to 30 percent from day to day, so one day proves nothing. The weekly average cuts through the noise. If your two weekly averages nearly match, and your eating was steady, that intake is your real maintenance.

The bottom line
A formula gives you a guess. Your body gives you the truth. The 14-day test turns daily noise into a number you can trust: eat your normal food, weigh each morning, log every bite in Burnie, and compare two weekly averages. When the averages stay flat, the calories you ate that week are your real maintenance. Hold that number, and your weight holds too.
