Calorie Tracker

What the Calorie Tracker Does

The Calorie Tracker keeps a running diary of everything you eat and compares it with your daily calorie goal. Set the goal once, pick a date, and log each food or drink with its calorie amount and the meal it belongs to. The tool immediately shows how many calories remain for the day, a progress bar toward your goal, and a per-meal breakdown for breakfast, lunch, dinner, and snacks. Everything is saved in your browser, so your food diary stays on your device.

How to Use the Calorie Tracker

1. Enter your daily calorie goal in the goal field. It is shared across every date.
2. Choose the date you want to track, or leave it on today.
3. Type the food or drink name, its calories, and select the meal.
4. Click Log food. The entry appears in the list and the totals update instantly.
5. Delete individual entries with the trash icon, or use Clear day to reset the selected date.

Choosing a Daily Calorie Goal

Your goal should come from your maintenance calories, also called TDEE (Total Daily Energy Expenditure). The Calorie Calculator estimates TDEE from your age, height, weight, sex, and activity level. From there:

• Maintain weight: set your goal equal to your TDEE.
• Lose weight: set a goal roughly 250 to 500 calories below TDEE.
• Gain weight: set a goal about 250 to 500 calories above TDEE.

The Calorie Deficit Calculator can help you translate a target rate of weight loss into a daily calorie number. If you prefer a starting point based on your body, the BMI Calculator gives useful context for a healthy weight range.

Why Logging Meals Works

Most people are poor at estimating how much they eat. Studies consistently show that self-reported intake underestimates actual intake, sometimes by a large margin, because small bites, drinks, and cooking oils are easy to forget. A food diary fixes that by forcing a quick moment of awareness with every meal. Even on days when you go over your goal, the log tells you by how much and where the calories came from. That feedback loop, not perfection, is what makes tracking effective.

Activity matters too. Calories burned through exercise, walking, and chores add to your daily expenditure. The Calories Burned Calculator estimates energy use across more than 100 activities using MET values, which is useful if you want to understand your full energy balance rather than just your intake.

Getting Realistic Calorie Numbers

The accuracy of any tracker depends on the numbers you feed it. Package labels are the easiest source, but portions matter: a serving is often smaller than what lands on your plate. Weighing food for the first week or two trains your eye, and after that you can estimate most meals closely. Restaurant meals and mixed dishes are harder, so use a calorie estimate from the restaurant when available, or a similar dish from a food database such as the USDA FoodData Central. The Meal Calorie Calculator is handy for breaking down complex meals and recipes into per-portion calories.

Your Data Stays in Your Browser

Food diaries are personal. This tracker stores every entry in your browser's local storage, which means nothing is uploaded, transmitted, or tied to an account. Closing the tab keeps your data, and clearing your browser's site data removes it permanently. If you switch devices or browsers, the diary does not follow you, which is the trade-off for keeping it completely private.

Tips for Consistent Tracking

• Log meals right after eating, not at the end of the day when details blur.
• Use the meal dropdown consistently so the breakdown stays meaningful.
• Include drinks, sauces, and cooking oils, which add up quickly.
• Aim for the weekly average rather than judging a single day.
• Pair your intake goal with hydration. The Water Intake Calculator estimates how much water you need daily.
