Dietary Modification, Eating Behavior, Glucose, Mood, Obesity
Conditions
Brief summary
The purpose of the study is to examine the effect of chia seed consumption on body composition, blood pressure, blood glucose, satiety, mood, joint pain, and dietary displacement in overweight and obese females (18-45years). It is hypothesized that consuming chia seeds will bring about a positive change in body composition (lower % body fat), satiety, mood, joint pain, and blood pressure, lower blood glucose levels, increased fiber and improved nutrient intake, in overweight/ obese females.
Detailed description
Specific Objectives: 1. Determine if chia seed diet addition of 10% of Kcals (CHIA) positively changes body composition in young, healthy, overweight/obese people (Tanita scale). A) Determine if CHIA will decrease blood pressure (monitor). 2. Determine if CHIA will decrease blood glucose (draw) 3. Determine if CHIA increases satiety and improves diet (recordings). 4. Determine if CHIA will decrease joint pain (questionnaire). 5. Determine if CHIA will increase positive mood changes (questionnaires) and increase blood serotonin levels (draw).
Interventions
Chia seed added-10% of kcals and a no-chia control diet. 10% will be calculated using the following formula: Harris-Benedict equation multiplied by the activity factor of 1.2, 1.375, and 1.55 depending on each participant's activity level based on the information provided on the initial screening form.
