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.

Dietary fat content influences both energy intake and body fat composition in mammals. By examining rats’ preference for high fat food in a series of choice experiments, it is possible to test genetic differences and pharmacological interventions on their preference for high fat food.

Milk is a primary source of nutrition for the neonate. Analysis of milk components may provide insight into maternal factors that affect offspring health. This protocol describes a manual method of collecting milk samples from the lactating rat, which can then be used for further downstream analysis.

The goal of this protocol was to develop a murine model of low-level toxicant exposure that does not cause overt liver injury but rather exacerbates pre-existing liver damage. This paradigm better recapitulates human exposure and the subtle changes that occur upon exposure to toxicant concentrations that are considered safe.
FAQs
The diet’s elevated fat content changes both energy density and nutrient composition, which can increase the likelihood of weight gain and adipose tissue expansion. These changes are accompanied by metabolic effects such as insulin resistance and dyslipidemia, while inflammatory responses may connect altered nutrition with broader physiological dysfunction relevant to disease research.
Variation in diet composition, feeding duration, and rat strain can change the magnitude or pattern of observed effects. Consequently, results from one experimental model may not automatically generalize to another model using a different diet or animal background. Reporting these conditions is essential when interpreting weight, metabolic, inflammatory, or cardiovascular findings.
Weight gain and adipose tissue expansion provide more than physical measurements: they indicate how excess dietary energy is being stored. When accompanied by insulin resistance, dyslipidemia, and inflammation, they form a connected metabolic profile that helps investigators examine how dietary excess may contribute to broader dysfunction rather than studying body mass alone.
A typical investigation begins by assigning rats a defined high-fat feeding regimen and maintaining it for a specified duration. Researchers then relate the resulting physiological changes to the diet composition and rat strain used. This design allows comparisons of how experimental conditions shape metabolic outcomes and helps establish a consistent disease-model context.
Researchers can examine weight gain, adipose tissue expansion, insulin resistance, dyslipidemia, and inflammation as outcomes of the dietary regimen. Together, these measurements characterize metabolic and physiological dysfunction more comprehensively than any single endpoint. The selected outcomes can also help connect experimental findings with obesity, diabetes, cardiovascular, or broader metabolic research.
In preclinical medicine, investigators test drugs, nutrients, or lifestyle interventions after establishing diet-associated dysfunction. The model can reveal whether an intervention changes relevant metabolic or physiological outcomes before clinical studies begin. It therefore supports both treatment-oriented testing and evaluation of preventive strategies aimed at reducing diet-related disease risk.
The model is especially relevant when a study addresses obesity, type 2 diabetes, cardiovascular disease, or metabolic dysfunction. Its value lies in connecting controlled dietary exposure with measurable physiological changes, allowing researchers to investigate disease mechanisms and compare preventive or therapeutic approaches within a laboratory setting before moving toward clinical research.
