Other forms: intakes
The act of consuming food can be called intake. A veterinarian might advise you to limit your dog's intake of pizza crusts, for example.
While the process of eating can be called your intake, unless you're a militant dieter who weighs every ounce of food you consume, you're most likely to hear the word intake in a hospital or doctor's office. Caregivers might be concerned about a patient's intake of calories if he's very sick, or a dietitian might recommend an elderly woman increase her intake of calcium.
