Fat freezing, also known as cryolipolysis, is a cosmetic procedure used to reduce localized pockets of fat by freezing fat cells. The procedure utilizes an applicator that is applied to the treatment area. This applicator, or "cup," cools the underlying fat to a temperature at which the fat cells are damaged but surrounding tissues are left unharmed.

The number of cups or applicators needed for a particular treatment session can vary depending on the patient's anatomy, the specific area being treated, and the size and model of the applicator being used.

Generally, here are common treatment areas and the typical number of cups that might be used:

1. **Abdomen**: 1-2 cups, depending on the size and shape of the fat deposit. Sometimes more might be used if treating the upper and lower abdomen separately.

2. **Flanks (love handles)**: Typically 1 cup for each side, so 2 cups in total.

3. **Inner thighs**: 1 cup per thigh, so 2 cups in total.  

4. **Outer thighs (saddlebags)**: 1 cup per thigh, so 2 cups in total.

5. **Upper arms**: 1 cup per arm, so 2 cups in total.

6. **Bra and back fat areas**: The number of cups will depend on the size of the area, but typically 1-2 cups for each side.

7 **Banana roll (below the buttocks)**: 1 cup per side, so 2 cups in total.

8. **Knees**: 1 cup per knee, so 2 cups in total.

It's important to remember that the number of applicators or cups needed can vary based on the individual, the equipment the clinic uses, and the desired outcome. Therefore, a consultation with a trained and certified practitioner is crucial to determine the exact number of cups required and to assess the potential results.

Additionally, some areas might need multiple treatment sessions to achieve the desired result, which is another factor to consider when determining the number of applicators needed.
