Summary

In addition to its role as the major regulator of glucose uptake into peripheral tissues, the hormone insulin is also a primary regulator of fat storage and fat burning of the body. Mechanistic animal studies have shown that high insulin may be the initial trigger for weight gain and be the proximal cause of obesity. There is currently no quick or non-invasive way of measuring insulin as research and clinical techniques require collection of a blood sample followed by a complicated and costly biochemical assay. The investigators will test the hypothesis that insulin levels can be accurately measured in saliva in humans following meals that elicit high and low blood insulin responses. Findings will help determine if insulin can be use as a valid fluid to track insulin changes in humans.

Conditions

Interventions

BEHAVIORAL

High-carbohydrate meal

Participants will consume a high-carbohydrate low fat meal. The macronutrients content will be 55% carbohydrate, 25% protein and 20% fat providing 400-500 kcal. Between interventions there will be at least a 48-hours washout, where participants are encouraged to return to their baseline dietary habits.

BEHAVIORAL

Low-carbohydrate meal

Participants will consume a low-carbohydrate high fat meal. The macronutrients content will be 10% carbohydrate, 25% protein and 65% fat and will provide 400-500 kcal (matched to the high carbohydrate meal). Between interventions there will be at least a 48-hours washout, where participants are encouraged to return to their baseline dietary habits.
