Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Resting Metabolic Rate and Respiratory Quotient is measured using indirect calorimetry for 30 minutes, gas exchange is determined by using a metabolic car (Vmax Encore 29n) 2. Estradiol and Progesterone concentration is measured using blood samples when the measurement of resting metabolic rate finishes 3. Sweet taste preference is measured using the Monell Forced-Choiced, Paired-Comparison Tracking Procedure when the other measurement are finished, at minute 45 | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Consumption of processed foods is measured using a consumer frequency survey at the end of the sweet taste preference procedure at one hour after the start of the session 2. Body mass and body composition is measured using the body mass index formula (BMI) (body mass divided by the square of the body height) and the body composition was measured by electrical bioimpedance at the beginning of the session *All measurements are made in the two sessions, corresponding to each menstrual phase. The day 1 for the menstrual cycle is the first day of bleeding, the range of days for the follicular phase (5-12), and for the luteal (21-27). | — |
