- Track for two to four weeks to learn portions, then decide whether you need to continue.
- Focus on calories and protein. Everything else is detail.
- Aim for consistent rather than perfect. Roughly right every day is plenty.
- If tracking makes you anxious or rigid, stop and use hand portions instead.
Why tracking works, and why it goes wrong
Most people are poor at estimating how much they eat. That is not a character flaw. Portion sizes are hard to judge by eye, and calorie-dense foods such as oil, nut butter, cheese and granola hide a lot of energy in a small volume. Tracking for a few weeks shows you where your calories actually come from.
It goes wrong when tracking becomes the goal rather than a tool. Chasing exact numbers to the last kcal, feeling guilty about going over or turning down meals out because you cannot log them is not useful. The aim is awareness, not control.
Used well, a few weeks of tracking is like driving lessons. You concentrate hard for a while, then the skills become automatic and you stop thinking about every gear change.
How to track well
- Pick one app and stick with it. Most popular apps have large UK food databases and barcode scanners.
- Buy a kitchen scale. A cheap digital one is fine. Weigh calorie-dense foods such as oil, butter, cereal, rice, pasta, cheese and nut butter.
- Be consistent with raw or cooked. Rice and pasta roughly double or triple in weight when cooked. Log them the same way every time and choose the matching database entry.
- Log as you go. Logging at the end of the day leads to forgetting. It takes ten seconds after each meal.
- Log the extras. Cooking oil, milk in tea, sauces, drinks and bites of the kids' tea are where most untracked calories live.
- Save regular meals. Most people eat a handful of the same meals. Saving them makes logging quick.
Do not weigh everything forever. After a couple of weeks you will know what 30 g of cereal or a tablespoon of oil looks like, and your estimates will be far better than they were.
What to track, and what to ignore
Keep it simple. Track total calories and protein. Hitting those two numbers on most days gets you most of the results. Carbs, fat, sugar, micronutrients and meal timing are secondary for fat loss, and if you eat mostly minimally processed food with plenty of fruit and vegetables, they tend to look after themselves.
Your calorie target should come from your own maintenance calories rather than an app's default setting. Think in weekly averages too. If you are 200 kcal over on Saturday, you do not need to compensate on Sunday. A couple of slightly higher days balanced by lower ones is how real eating works.
Good enough accuracy
Food labels are allowed a margin of error, databases are imperfect and restaurant portions vary. Perfect accuracy is not possible, and it is not needed. What matters is being consistently roughly right, so your weekly average and your weight trend line up.
For meals out, pick the closest match and move on. Larger chains in England, those with 250 or more employees, must show calories on their menus, which helps. For home-cooked meals, log the recipe once and save it. When unsure, round up. Alcohol is the category people most often leave out, so log it like any other drink; a couple of pints or large glasses of wine can be several hundred kcal.

When to stop tracking
Tracking is a phase. Once you have hit your targets consistently for a few weeks, you have options:
- Keep tracking: some people like the data and find it easy. That is fine.
- Track only protein: a lighter version that keeps the most useful habit.
- Spot check: track one week in every four to make sure nothing has drifted.
- Switch to hand portions: the hand portion guide keeps the structure without the numbers.
Many people find a few weeks of tracking permanently changes how they see food. They know the difference a spoonful of mayonnaise makes and choose accordingly, no app required. If you step down and your weight trend starts creeping up, that is not failure, just a signal to spot check for a week.
When tracking is not for you
Tracking is not right for everyone. If you have a history of an eating disorder, or you notice that tracking makes you anxious, guilty, secretive or rigid about food, stop. Use structure without numbers instead, such as hand portions, regular meals and mindful eating habits.
Warning signs to take seriously include panicking when you cannot log a meal, skipping social events because of food, exercising to cancel out what you ate, or feeling out of control around food. Talk to your GP, and the UK charity Beat has support and information on eating disorders. Our guide to emotional eating may also help.
Using the numbers well
Tracking earns its keep when you use it to make decisions, not just to keep a record. Look back over a week and ask simple questions. Where are most of my calories coming from? Which meals are low in protein? Which snacks are not worth what they cost? Small changes to two or three regular meals usually matter more than anything else.
Common discoveries in the first fortnight include:
- Cooking oil adding 200 kcal or more a day.
- Milky coffees quietly adding up to a small meal.
- Breakfast and lunch low in protein, with dinner making up for it.
- Evening snacks adding more energy than an entire meal.

Questions
Do I need to count calories to lose weight?
No, but tracking for a few weeks is one of the quickest ways to learn portion sizes and spot hidden calories. Hand portions are a good alternative.
Should I weigh food raw or cooked?
Either works if you are consistent and use the matching database entry. Raw weights are usually more accurate for meat, rice and pasta.
Which calorie tracking app is best?
The one you will actually use. Look for a large UK food database, a barcode scanner and the option to save meals and recipes.
How accurate does calorie counting need to be?
Consistently roughly right is enough. Weigh calorie-dense foods, log the extras and judge progress by your weekly weight trend.
