The friend who eats more and weighs less — a different body's maths
You watch a thin friend polish off a third roti and feel cheated. Their body's maths is not your body's maths. Different height, muscle, NEAT, genes, and history make their plate a bad ruler for yours.
You sit with a friend. She eats two rotis, a heap of paneer, a full katori of rice, and a gulab jamun. You eat one roti, a little dal, and you still gain. It feels unfair. You think, 'If she can eat that much and stay thin, why can't I?' Here is the honest answer. You are not looking at the same maths. Her body's numbers are not your body's numbers. Comparing her plate to yours is like comparing a Maruti's mileage to a truck's. This short read is about why that is, and how to stop the comparison game in your head.
If my thin friend can eat three rotis and stay thin, then three rotis should keep me thin too.

Same food does not mean same result. Your friend may be taller, more muscled, younger, more fidgety, or simply moving more through the day. Each of these changes the maths of how much her body burns. The food is only one half of the equation. The other half is her body's burn, and that number is hers alone, not yours. So copying her plate tells you nothing about what your body will do with it.
Different bodies, different resting burn
Your BMR is the calories your body burns just to stay alive. Even this calm number is different from person to person. Adult women average about 1300 to 1500 kcal a day at rest. Adult men average about 1600 to 1800 kcal a day. Taller and more muscled people burn more, even when they sit still. Fat-free mass (your muscle and organs) is one of the strongest things that sets this number. So a taller friend with more muscle may quietly burn a few hundred extra calories every day before she even walks anywhere.
Three hidden reasons your friend's maths is different
My friend eats more than me, so my deficit must be wrong.

Your deficit is food calories minus your own BMR and active calories. Your friend's plate never enters that equation. You can only build a deficit against your own body's burn, not hers. When you copy a thin friend's plate, you are borrowing her maths and pasting it on your body. The numbers will not match, because the bodies do not match. Log honestly what you eat, trust your own BMR, and let her plate be her plate.

The bottom line
Your friend who eats more and weighs less is not cheating. Her body is doing different maths — different height, muscle, NEAT, genes, sleep, history. NEAT alone can swing by up to 2000 kcal a day between two people of the same size. So copying her plate tells you nothing about your own body. Log your food in Burnie, build your deficit against your own BMR and active calories, and let her thali be hers. Your maths is yours. Burnie is FREE, so the number is yours to learn from, not to fear.
