Does Protein Turn Into Carbs? What to Record in Your Diary
·
Log dietary protein as protein according to the food label or matching database entry. The body can make glucose from non-carbohydrate substrates, but that does not mean you should relabel protein grams as carbohydrate in a food diary.
A practical example
| Check | How to apply it |
|---|---|
| Protein label | Record the stated protein grams |
| Carbohydrate label | Record the stated carbohydrate grams |
| No conversion | Do not add a second invented macro entry |
Keep intake accounting separate from metabolism
A serving with 25 g labelled protein is recorded as 25 g protein. Do not add another 25 g carbohydrate because you read that amino acids can be used to make glucose. That would count energy twice in the log.
A basic diary describes what was consumed; it does not directly measure the metabolic fate of each nutrient.
Use actual labels for mixed foods
A shake or bar may contain both protein and carbohydrate. Record each labelled amount for the serving eaten, including fat and total energy. BiteCal estimates should be reviewed against a package label when one is available.
