Study Summary

This trial is an 8-week weight loss intervention with 3 randomly assigned groups: DIET, cold exposure (CE), and DIET+CE. The study will last a total of 13 weeks. All participants will have a screening session, two experimental sessions at baseline, and two experimental sessions after the intervention.

Who is the study for?
This trial is for English-reading, sedentary adults with obesity (BMI of 27 or greater and waist circumference >88 cm), who have been weight-stable in the last 6 months. Participants should be pre-menopausal women with regular menstrual cycles and no history of alcohol or drug abuse. Those with certain medical conditions, high blood pressure, cholesterol levels, or on specific medications are excluded.Check my eligibility
What is being tested?
The study tests an 8-week weight loss intervention comparing three groups: diet only (DIET), cold exposure only (CE), and a combination of both (DIET+CE). Each group will undergo lab sessions before and after the intervention to measure effects. The DIET groups receive weekly nutritional consultations; CE groups attend bi-daily cold exposure sessions.See study design
What are the potential side effects?
Potential side effects are not explicitly listed in the provided information but may include discomfort from cold exposure such as chills or shivering, hunger from caloric restriction, possible changes in mood or energy levels due to dieting.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Only diet groupExperimental Treatment1 Intervention
Dietary energy prescription at -30% of Energy requirements (50% carbohydrate; 30% fat; 20% protein) during 8 weeks. Follow up with a registered dietitian.
Group II: Only cold exposure groupExperimental Treatment1 Intervention
No dietary intervention. Visit at laboratory every 2nd day during the 8-week intervention to undergo the cold exposure as follows: 2 weeks of exposure at 18 degrees, 2 weeks of exposure at 14 degrees and 4 weeks of 10 degrees of exposure during 90 min.
Group III: Combined diet + cold exposure groupExperimental Treatment1 Intervention
Dietary energy prescription at -30% of Energy requirements (50% carbohydrate; 30% fat; 20% protein). Follow up with a registered dietitian. Visit at laboratory every 2nd day during the 8-week intervention to undergo the cold exposure as follows: 2 weeks of exposure at 18 degrees, 2 weeks of exposure at 14 degrees and 4 weeks of 10 degrees of exposure during during 90 min.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What are the primary aims of this medical research?

"This clinical trial will assess its primary outcome over an 8 week period, which is the variation of post-prandial desire to eat as indicated through a Visual Analogue Scale. Secondary objectives are tracking resting energy expenditure and explicit wanting using the Leeds Preference Food Questionnaire (LFPQ), in addition to olfaction measured with Sniffin Sticks tests at 90 minutes after breakfast both before and after intervention."
