|
|
Requires a client to name all food eaten within a day. It is simple and requires no equipment but can be inaccurate.

Asks the client to identify the number of times per day, week, or month a particular food group is eating. Accuracy can be a problem.
|
Food frequency questionnaire

|
Food record
|
|
Skin fold measurements
|
- take measurements directly on skin, not through clothing
