Diet Tracker Template — Auto-Calculate Calories & Macros
Log your meals and automatically calculate calories, carbs, protein, and fat. Perfect for weight loss, bulking, or maintaining a balanced diet.
Sticking to a diet is hard enough without having to manually calculate every calorie. This diet tracker lets you log meals and instantly see your calorie and macronutrient totals — so you can focus on eating well, not doing math.

How to Use
Step 1: Set Your Goals
In the “Setup” sheet, enter your current weight, target weight, and activity level. The template calculates a recommended daily calorie target (TDEE). Adjust it based on whether you’re cutting, maintaining, or bulking.
Step 2: Log Your Meals
Each day, record what you eat in the “Meal Log” sheet. Start typing a food name and the autocomplete will suggest matches from the database.
Step 3: Review Your Progress
Check the daily summary for calorie and macro breakdowns. The “Weekly Report” sheet shows trends over time.
Tips
Hit Your Protein Target
Set your protein goal to 1.5–2g per kg of body weight for muscle building. Days where protein falls short are highlighted in red so you can adjust your next meal.
Pair with Intermittent Fasting
If you practice 16:8 fasting, simply log lunch and dinner only. The meal-time column helps you track your eating window.
Best Practices
Log Meals Immediately After Eating
Waiting until the end of the day to log meals leads to forgotten snacks, underestimated portions, and inaccurate totals. Open the Meal Log sheet right after each meal and enter the items while they are fresh in your mind. Studies consistently show that real-time food logging improves dietary adherence by 30-40% compared to delayed recall logging.
Weigh Portions for the First Two Weeks
Eyeballing a “cup of rice” or “a handful of almonds” can be off by 50% or more. Use a kitchen scale for the first two weeks to calibrate your visual estimates. After that, your portion guesses will be much more accurate. Enter the actual gram weight in the serving size column for precise calorie calculation from the nutrition database.
Focus on Weekly Averages, Not Daily Perfection
One day over your calorie target does not ruin your progress. Check the Weekly Report sheet to see your 7-day average instead of fixating on daily numbers. A consistent weekly average within 100 calories of your target is far more effective than alternating between strict restriction and overeating. The weekly trend chart is specifically designed to show this bigger picture.
FAQ
What if a food isn’t in the database?
Add it manually in the “Food DB” sheet. Enter the food name and nutrition values per 100g — the tracker will use it immediately.
How accurate are the calorie calculations?
The built-in database uses standard USDA-equivalent nutrition data. Actual values vary by cooking method and ingredients, so treat the numbers as a reliable guide rather than exact science.
How do I track homemade recipes with multiple ingredients?
Add your recipe to the Food DB sheet as a single entry. Calculate the total calories and macros by summing each ingredient, then divide by the number of servings to get per-serving values. For example, if a pot of soup has 1,800 calories total and serves 6, enter 300 calories per serving. This lets you log the recipe by name in the Meal Log without re-entering individual ingredients each time.
Should I adjust my calorie target as I lose weight?
Yes. As your body weight decreases, your Total Daily Energy Expenditure (TDEE) drops because a lighter body burns fewer calories at rest. Re-enter your updated weight in the Setup sheet every 2-4 weeks. The template will recalculate your recommended daily calorie target automatically. Ignoring this adjustment is a common reason weight loss plateaus after the first few months.
