How to track calories in home cooked meals

Packaged food is easy to track because someone already did the arithmetic and printed it on the box. Home cooking has no box. What you have instead is a pot containing the sum of eight ingredients, from which an unknown number of servings will come out.

This is why home cooking is where most people abandon logging, and it is worth saying plainly: it is not a discipline failure. Logging a stew properly the first time genuinely takes several minutes, and doing that every evening is not sustainable. The fix is to restructure the work rather than to try harder.

Restructuring means two things. Count each recipe once and reuse it, and be deliberately approximate about the ingredients that barely move the total.

Add ingredients in the order they matter, and spend your attention accordingly:

• Fats first. Oil, butter, cream, coconut milk, cheese. These are the densest things in the pot and the easiest to underestimate. Log the oil as you pour it, not from memory afterwards.
• Then the starches. Rice, pasta, potatoes, flour. Log them dry, by the amount you actually put in, because cooked weight depends on absorbed water.
• Then the protein. Use the raw weight from the packet; that number is already in front of you.
• Vegetables, aromatics and spices last, quickly. Onions, garlic, herbs and a tin of tomatoes are not going to change the outcome of your week. Approximate them and move on.

Then save the result as a recipe or a meal. The point of the first careful pass is that it is the only careful pass. Every subsequent time you cook that dish you are logging one saved item and a portion count.

Once the recipe total exists, you need to divide it, and there are three ways to do that in descending order of accuracy:

• Weigh the cooked total. Weigh the full pot of food, note the weight, then weigh your own serving. Your share is your serving divided by the total. This is the most accurate method available at home and it requires one extra weighing.
• Divide into visibly equal servings. Portion the whole batch into identical containers, then log one container as one share. Batch cooking makes this almost free, since you were dividing it anyway.
• Estimate the fraction. Decide that you took roughly a quarter or a third of the pot. Fastest, least precise, still much better than not logging.

Batch cooking deserves the extra mention because it works in your favour twice. You cook once, and you also count once: divide the recipe total into portions, log the same saved portion each day, and the tracking cost of the next four dinners is effectively zero.

To know how many portions you should be aiming for in a day, start from a target rather than from the pot. The daily calorie calculator gives you that number.

Where home cooked tracking stays imprecise:

• Your share of a shared dish. Even with an exact recipe total, how much of the pot ended up on your plate rather than someone else's is estimated unless you weighed it.
• Uneven distribution. A ladle from a stew can come up mostly sauce or mostly meat. Averaged across a week this evens out; on any single day it does not.
• Cooking losses and additions. Water evaporates, some oil stays in the pan, some sauce stays in the pot. These are usually small, and chasing them is not worth the effort.
• Casual additions. The cheese grated on top, the extra splash of oil, the tasting spoonfuls while cooking. These are easy to forget and not always trivial.

GATA calorie tracker lets you describe the dish instead of assembling it. You say or type what you cooked, in ordinary language, and the app breaks the description into ingredients with calories and macros for each one. For home cooking this is usually faster than a photo, because a description can include the things a finished dish hides, such as the oil and the cream.

From there the entry behaves like any other: individual ingredients can be corrected, portions adjusted in a tap, and the meal saved so the next time you cook it you reuse it rather than rebuild it. Your share of a pot shared with other people is still your own judgement, and the app cannot resolve that for you. Details are on the GATA calorie tracker page.
