This is a high fat diet feeding protocol to induce obesity in Drosophila, a model for understanding fundamental molecular mechanisms implicated in lipotoxicity. It also provides a high throughput triacylglyceride assay for measuring fat accumulation in Drosophila and potentially other (insect) models under various dietary, environmental, genetic or physiological conditions.

This video describes a feeding assay for fruit flies in which colored food is used to monitor feeding and the effect added compounds may have on feeding activity. The example protocol tests the effects of several endocrine disrupting chemicals (EDC).
FAQs
Over time, the calorie-dense intake creates an energy surplus that favors lipid accumulation. That accumulation is associated with chronic low-grade inflammation, while the altered metabolic state can impair insulin signaling. These linked changes allow investigators to examine nutrition as a contributor to disease rather than treating obesity, inflammation, or insulin dysfunction as isolated findings.
Fat, refined carbohydrates, and cholesterol represent complementary dietary pressures in the model. Their enrichment supports excess calorie intake and lipid storage, while the resulting metabolic environment is associated with inflammation and impaired insulin signaling. The combination helps researchers study interconnected metabolic changes that accompany disease, rather than focusing on a single nutrient effect.
Duration matters because the model is intended to capture changes that emerge over time. Early exposure may represent the beginning of energy surplus and lipid accumulation, whereas longer feeding can reveal persistent inflammation, impaired insulin signaling, and broader disease-related consequences. Researchers can therefore relate observed outcomes to the progression of diet-associated dysfunction.
Researchers can use the feeding paradigm to evaluate dietary, pharmacological, and lifestyle interventions against diet-associated dysfunction. The model provides a nutritional context in which investigators can ask whether an intervention changes obesity, metabolic impairment, fatty liver disease, cardiovascular risk, or related complications. Its value lies in testing effects within a disease-promoting exposure.
Applications extend across several medical outcomes, including obesity, metabolic dysfunction, fatty liver disease, cardiovascular risk, and related complications. The dietary challenge can connect these outcomes through shared features such as lipid accumulation, chronic low-grade inflammation, and impaired insulin signaling. This breadth makes the approach useful when a study examines multisystem consequences of nutrition.
In medicine, Western diet feeding supports two complementary goals: clarifying how nutrition contributes to disease and assessing possible responses to intervention. Investigators can use the resulting animal model to examine mechanisms that link dietary exposure with metabolic and cardiovascular consequences, then study candidate dietary, drug-based, or lifestyle strategies in that context.
