What this trial studies
This research aims to clarify how different types of dairy products, specifically full-fat and low-fat, affect health and weight management in both adults and children. The study will involve families with at least one parent who is obese, and will implement a web-based nutrition intervention to promote increased dairy consumption over an 8-week period. Participants will be randomly assigned to one of three groups: one promoting low-fat dairy, one promoting full-fat dairy, and a control group with no intervention. The study will assess various health metrics, including body weight, diet quality, and metabolic health, before, immediately after, and three months post-intervention.
Who should consider this trial
Good fit: Ideal candidates include families with at least one parent aged 18-55 with obesity (BMI 30-40) and children aged 8-16.
Not a fit: Patients who are not part of a family unit or those with allergies to dairy products or lactose intolerance may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide insights into how dairy consumption impacts weight management and metabolic health, potentially leading to improved dietary recommendations.
How similar studies have performed: While there is existing research on dairy consumption and health, this specific approach of comparing full-fat and low-fat dairy in a family-based intervention is relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: Parent criteria are as follows: * men and women between 18-55 years * body mass index (BMI) between 30-40 kg/m2 * absence of pregnancy, breastfeeding or menopause (no menstruation) * stable body weight (weight change \<5 kg for three months prior to screening). Family criteria are as follows: * being a family composed of at least one parent (mother/father) and at least two children between 8 to 16 years old (families between 3 to 5 persons). Families with at least one obese parent (BMI between 30-40 kg/m2) will be recruited since children coming from these families are more at risk of developing obesity and may benefit more from dairy products * all participants should have no allergies to dairy products or lactose intolerance and be in good general health. * since we are recruiting adults with obesity and dairy products may positively impact several metabolic markers, those with hypertension or deteriorated blood glucose and lipid profiles and/or taking medications will also be considered.
