Upon tube feeding initiation determined by the HNC multidisciplinary team, the patients will be randomized into three different groups, each consisting of 20 patients each: Bolus (Group 1), Gravity (Group 2), and Pump (Group 3). The randomization process within these three groups will based on 1) age and 2) estimated caloric need. For example, if we have three 60-year-old patients whose estimated kcals needs are ≤ 1900kcals/day, then each patient will be randomized to either Bolus, Gravity or Pump group. Another example is that if we have two 45-year-old patients whose estimated needs are 2400kcals/day, then one patient will randomly be assigned to the Bolus group, and the other one will be randomly assigned to the Gravity group. The third patient that will fit that category will be assigned to the Pump group.

The patients will be randomized into 3 different groups: Bolus, Gravity, and Pump. The randomization process will be based on age and estimated caloric needs (i.e if we have three 60-year-old patients whose estimated kcals needs are ≤ 1900kcals/day, then each patient will be randomized to either of the groups).

Each patient from each group will be receiving tube feeding education to their by RD. For consistency reasons, the same type of tube feeding formula (1.5 kcal/ml, no fiber) will be used. Patients' weight, tube feeding tolerance, and amount of estimated calories and protein met will be monitored weekly.
