What should I track when counting calories?

Track all food and beverages including meals, snacks, cooking oils, condiments, and drinks. Calco's photo logging makes this quicker; add oils and condiments that a photo may not show.

Calorie Goals & Requirements

How many calories should I eat per day?

Daily calorie needs vary by person: women typically need 1,600-2,400 calories per day, men need 2,000-3,000 calories per day, depending on age, height, weight, and activity level. Calco suggests a daily calorie goal that you can adjust. (Dietary Guidelines for Americans)

How do I calculate my daily calorie needs?

Calculate your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, then multiply by your activity level factor. Calco does this calculation automatically when you set up your profile.

Should I eat back calories burned through exercise?

If you're following a TDEE-based calorie goal (includes exercise), don't eat back exercise calories. If using BMR + exercise logging, eat back 50-75% of exercise calories to account for overestimation.

Weight Loss Questions

Can you lose weight by counting calories?

Yes, you can lose weight by counting calories. Creating a calorie deficit (eating fewer calories than you burn) leads to weight loss over time. Research on self-monitoring suggests that people who track their food regularly tend to do better than those who do not.

How long does it take to see results from calorie counting?

Many people notice early changes on the scale within 1-2 weeks, partly from water. Fat loss trends usually become clearer over several weeks of consistent tracking.

How much weight can I lose per week with calorie counting?

The CDC notes that people who lose weight gradually, about 1-2 pounds per week, are more likely to keep it off (CDC). A smaller deficit is more sustainable than a very large one.

Why am I not losing weight despite counting calories?

Common reasons include underestimating portions, not tracking everything, overestimating exercise calories, or needing to adjust your calorie goal. Weighing food now and then helps you check your portion estimates.

Accuracy & Tracking Questions

Are calorie counting apps accurate?

Calorie counting apps give estimates, not exact measurements. Accuracy depends on portion sizes, the nutrition data, and how completely you log. Calco estimates calories and macros from a photo, and you can adjust portions. Weighing food on a kitchen scale is the most precise method.

How do I track calories when eating out at restaurants?

Use restaurant nutrition information when available, search for similar menu items in your app's database, or estimate portion sizes using visual guides. With Calco, you can take a photo of your plate to get an estimate, then add any sauces or oil you suspect.

Do I need to weigh all my food?

Weighing food provides the highest accuracy, but it's not always necessary. Use nutrition labels for packaged foods and visual portion guides for whole foods. Weighing is most important for calorie-dense foods like nuts and oils.

What foods are surprisingly high in calories?

Nuts, oils, restaurant salads with dressing, smoothies, granola, and avocados are surprisingly high in calories. Logging them, including small amounts, helps you see where hidden calories come from.

Nutrition & Health Questions

What's the difference between calories and macros?

Calories measure energy content, while macros (macronutrients) break down the protein, carbohydrates, and fat composition of foods. Calco tracks both calories and macros for complete nutritional insight.

Is calorie counting safe and healthy long-term?

Yes, calorie counting is safe when done mindfully and focuses on nutrition quality too. Tracking protein, carbs, and fat alongside calories helps you keep an eye on balance. If tracking causes stress or affects your relationship with food, take a break and talk to a professional.

Should I count calories on weekends and holidays?

Consistency leads to better results, so tracking on weekends helps maintain awareness. You can be more flexible with your calorie goals on special occasions while still logging to maintain the habit.

Do all calories count the same for weight loss?

For weight loss, calories in vs. calories out is what matters most. However, protein calories have higher thermic effect, and fiber-rich foods can affect satiety and digestion.
