A Beginner's Guide: How to use a food weighing scale?

Using a food weighing scale can increase the accuracy of your calorie tracking by as much as 20% compared to estimating, making it a game-changer for anyone serious about nutrition. This guide will walk you through everything you need to know about how to use a food weighing scale effectively for your health goals.

Quick Summary

This guide provides essential steps for using a food scale, covering basic functions like taring, unit conversion, and weighing ingredients for precise portion control and accurate calorie counting.

Key Points

• Tare/Zero Function: Always use the tare or zero button to eliminate the weight of your container and measure only the food itself.

• For Precision, Use Grams: Weighing in grams offers the highest accuracy and aligns best with most nutritional information.

• Weigh Raw, Not Cooked: For the most accurate calorie and macro tracking, weigh foods like meat and grains in their raw state.

• Use for Portion Control: A food scale eliminates the guesswork of portion sizes, preventing overconsumption of calorie-dense foods.

• Integrate with an App: Log the exact weight from your scale into a nutrition tracking app for seamless and accurate macro and calorie counting.

• Calibrate Regularly: Periodically calibrate your digital scale with a known weight to ensure its accuracy over time.

• Position for Accuracy: Always place your scale on a flat, stable, and level surface to avoid inaccurate readings.

Why Use a Food Weighing Scale?

Guessing portion sizes is a major pitfall in dieting and nutrition. What looks like a single serving of cereal or pasta can often be double or triple the recommended amount, leading to a significant underestimation of daily caloric intake. A food scale removes this guesswork, providing an objective, reliable measurement that empowers you to make informed decisions about your food intake. For individuals tracking macronutrients, managing health conditions like diabetes, or simply wanting a better understanding of their diet, a food scale is an indispensable tool.

Step-by-Step Instructions: How to use a food weighing scale

Using a digital food scale is a straightforward process that anyone can master. Here’s a simple, foolproof method to get you started on the path to accurate portioning.

1. Prepare and Power On

• Place on a flat, stable surface: To ensure accuracy, always place your scale on a level, solid countertop, away from vibrations or drafts.
• Power on: Press the power button and wait for the display to show zero. Most digital scales warm up quickly.

2. Use the Tare Function

The 'tare' or 'zero' function is the most important feature of a digital food scale. It allows you to subtract the weight of the container, so you only measure the food inside.

• Place your container: Put your empty bowl, plate, or glass on the scale. It will display the container's weight.
• Press 'tare': Press the tare button, and the display will reset to zero. You are now ready to add your food.

3. Weigh Your Food

• Add your ingredients: Gently add the food item you wish to measure. The scale will display the exact weight in your chosen unit.
• Portion multiple ingredients: If you are measuring multiple items in the same bowl, use the tare function again after adding each ingredient. For example, weigh your yogurt, tare the scale, then add your berries and see their individual weight.
• Weighing from a container: For items like peanut butter, place the full jar on the scale and tare it. Scoop out your desired portion. The scale will display a negative number, which is the precise weight of the portion you removed.

4. Switch Units

Many digital scales offer multiple units of measurement, such as grams (g), ounces (oz), pounds (lbs), and milliliters (ml).

• Press the 'unit' or 'mode' button: Cycle through the available units until you find the one you need. Grams are often recommended for the highest precision in nutrition tracking.

Weighing Food Raw vs. Cooked

For precise nutritional tracking, a key consideration is whether to weigh food raw or cooked. The weight and nutrient density of many foods, especially meats, change during the cooking process due to moisture loss or absorption.

• Raw food: For the most accurate tracking, especially for protein sources like chicken, it is best to weigh and log the food in its raw state. This aligns with the nutritional information found in most food tracking databases.
• Cooked food: If you must weigh food cooked, ensure you log it using cooked food entries in your tracking app, as the calorie density per gram will be different. Always be consistent with your method.

Benefits of Using a Food Scale for Your Diet

Adopting a food scale into your nutritional routine offers numerous advantages for managing your diet and health.

Precision in Portion Control

One of the main benefits is the elimination of guesswork. Measuring cups, spoons, and eyeballing are notoriously inaccurate, especially for calorie-dense items like nuts, oil, or grains. A food scale provides exact weights, ensuring you consume the precise serving size intended.

Mindful Eating and Awareness

The act of weighing your food helps cultivate mindfulness around your eating habits. It makes you more aware of what a true serving size looks like, which can help you develop better portion-sizing skills over time, even without the scale.

Consistent Results

For meal preppers and home cooks, weighing ingredients ensures recipes turn out consistently every time. This is especially crucial for baking, where accuracy is key to success.

Best For	Precise portion control, macro counting, and baking.	General kitchen tasks where high precision is not required.

How to Calibrate Your Food Scale

Digital scales can lose accuracy over time due to temperature changes or rough handling. Calibrating your scale periodically ensures it remains accurate. Always refer to your scale's user manual for specific instructions, but the general process involves entering a calibration mode and using a known, standard weight to reset the scale. A US nickel weighs exactly 5 grams and can be used for a quick check.

Integrating a Food Scale into Your Diet

Once you understand how to use your scale, integrating it into your daily routine is the next step. For diet tracking, weigh each food item before you eat it and log the precise weight into a nutrition app like MyFitnessPal or MacrosFirst. This process gives you the most accurate data for your calorie and macronutrient intake, enabling you to adjust your diet with precision and achieve your goals more efficiently.

Conclusion

A food weighing scale is a powerful tool for anyone committed to a healthy and nutritious diet. By mastering simple techniques like using the tare function and understanding the difference between weighing raw versus cooked foods, you can eliminate the inaccuracies of estimation and take full control of your nutrition. The initial effort of weighing your food pays off exponentially in the form of better dietary awareness, consistent cooking results, and a more effective path toward your health and weight management goals.
