Official title
Effect of Menstrual Cycle Phases on Postprandial Triglyceride Concentrations in Healthy Premenopausal Females: A Crossover Study
Overview
The goal of this clinical trial is to investigate the effect of menstrual cycle phases on postprandial triglyceride concentrations in healthy young female adults. The main question it aims to answer is: do postprandial triglyceride concentrations differ between the follicular and luteal phases of the menstrual cycle? Participants will: visit the laboratory for a preliminary screening session to assess eligibility, and undergo two experimental sessions consisting of six hours of seated rest following the consumption of a high-fat meal (one session conducted in the early follicular phase, and one session conducted in the mid-luteal phase of the menstrual cycle).
Interventions
- Other Early Follicular Phase
In the early follicular phase of the menstrual cycle, participants will undergo 6 hours of seated rest after the consumption of a high-fat meal representing 33% of estimated daily energy expenditure and consisting of 59% of calories from fat. - Other Mid-Luteal Phase
In the mid-luteal phase of the menstrual cycle, participants will undergo 6 hours of seated rest after the consumption of a high-fat meal representing 33% of estimated daily energy expenditure and consisting of 59% of calories from fat.
