There are several ways to track your food and calorie intake. Here are some of the most common methods:

1. Food Diary: You can use a notebook, an app, or a website to track your food intake. Write down everything you eat and drink throughout the day, and calculate the calories for each item.

2. Calorie Tracking Apps: There are many free and paid apps available for download that allow you to track your food intake and calculate the calories. Some popular options include MyFitnessPal, Lose It!, and Cronometer.

3. Fitness Trackers: Many fitness trackers, such as Fitbit, Garmin, and Apple Watch, have built-in calorie tracking features that can help you monitor your food intake.

4. Food Scale: Using a food scale can help you accurately measure the portion sizes of your food, which can be helpful when tracking your calorie intake.

5. Nutrition Labels: Most packaged foods have a nutrition label that lists the calorie and nutrient content per serving. You can use this information to calculate your calorie intake.

It's important to note that tracking your food and calorie intake should be done in conjunction with a healthy diet and lifestyle. It's also important to consult with a healthcare professional before making any significant changes to your diet or exercise routine.

To track your food intake you should be using a food scale and measuring cups to have an accurate account of your daily calorie consumption. 

Almost all items you intake will have calories, so you should be keeping track of anything you drink or eat.

For solids, meats or proteins are usually measured in ounces. Other foods like carbs, grains, and so forth are normally measured in grams.

Liquids like juice, milk, and so forth will be measured in both ounces and milliliters.
