high carbohydrate-high fat diet-induced rat model (cafeteria diet)

Cafeteria-style hypercaloric feeding in rats produces obesity, dyslipidemia, hyperinsulinemia, glucose intolerance, insulin resistance, hyperglycemia and inflammation.

**Measurement of Blood Glucose ** **Measurement of Blood Glucose ** Blood samples were collected from the tail vein for the determination of blood glucose levels using Accutrend Plus test strips and meter (Roche).

Model identity

Model name
high carbohydrate-high fat diet-induced rat model (cafeteria diet)
Species
rat

Biological characteristics

Phenotype stage
Hyperphagia and weight gain begin within days; full metabolic-syndrome picture develops over 8-16 weeks depending on diet mix.
Research questions
Palatable-diet overconsumption, hypothalamic leptin resistance, and the most complete metabolic-syndrome spectrum among dietary rat models.
Limitations
Cafeteria compositions vary widely between laboratories, making cross-study comparison difficult; intake is voluntary so caloric load is inconsistent across animals.
