-If low to absent carbohydrate intake with insufficient hepatic gluconeogenesis, clinical signs of hypoglycemia can occur (e.g., lethargy, depression, seizures). Blood sugar concentrations below the normal laboratory reference interval (<5 mmol/L) will be seen on serum biochemistry profiles.

-Starch is found in cereal grains, tubers, and pulses (i.e., legumes). Resistant starches can be formed during the cooking of digestible starches. Maltodextrin is not commonly found in pet foods, but can be included as a thickener in foods intended for human consumption.
