About this study

Official title: The Effect of a Diet Intervention Supplemented With Curd Cheese on Anthropometric Measurements, Glycemia, and Lipidemia in Adults Applying to Darıca Healthy Life Center

This randomized controlled trial aims to evaluate the effects of a diet supplemented with curd cheese on anthropometric measurements, glycemia, and lipid profile in overweight adults. Participants aged 40-64 years with a BMI above 25 will be randomly assigned to an intervention group receiving 100 g of curd cheese at breakfast for 8 weeks or to a control group receiving a standard healthy diet without curd cheese. Primary outcomes include changes in fasting blood glucose and HbA1c, while secondary outcomes are changes in body composition, waist circumference, and lipid profile (HDL, LDL, triglycerides, total cholesterol).

Read the detailed description

Metabolic disorders, including obesity, dyslipidemia, and type 2 diabetes mellitus, are major public health concerns worldwide. Dietary protein quality and source have been shown to play important roles in regulating glucose and lipid metabolism. Whey-derived proteins are rich in branched-chain amino acids and bioactive peptides that may enhance insulin sensitivity, promote satiety, and improve lipid profiles.

Curd cheese (lor cheese) is a traditional dairy product obtained during whey processing, characterized by its high-quality protein, low fat content, and rich calcium composition. It represents an affordable and accessible food that could be incorporated into dietary interventions targeting metabolic health improvement.

This study aims to investigate the effects of a curd cheese-supplemented diet on anthropometric parameters, glycemic control (including fasting glucose and HbA1c), and lipid profile (total cholesterol, HDL, LDL, and triglycerides) in adults attending the Darıca Healthy Life Center. Participants will follow a controlled dietary intervention with or without curd cheese for eight weeks.

The hypothesis of this study is that regular consumption of curd cheese as part of a balanced diet may improve metabolic parameters through increased protein intake, better glycemic regulation, and enhanced lipid metabolism.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Curd Cheese Supplemented DietDietary supplement

    This intervention consists of daily consumption of 100 grams of curd cheese as part of a personalized dietary plan for 8 weeks. Curd cheese is consumed at breakfast and integrated into the participants' regular meal plans. The diet is balanced for total energy and macronutrient distribution according to individual nutritional needs. All participants in this arm receive the same type and brand of curd cheese throughout the intervention period.

Study groupRoleWhat they receive
Curd Cheese Supplemented Diet GroupExperimentalIntervention Group - Arm Description: Participants in this arm follow a customized dietary plan for 8 weeks that includes daily servings of curd cheese. The diet is balanced for energy and macronutrient distribution according to individual needs. Curd cheese, as a high-quality protein and calcium source, is included to assess its specific effects on glucose and lipid parameters. This arm is designed to evaluate the unique metabolic effects of curd cheese supplementation compared to the control group.
Receives: Dietary Supplement: Curd Cheese Supplemented Diet
Standard Diet GroupNo interventionParticipants in this arm follow a standard dietary plan for 8 weeks without curd cheese. The diet is balanced according to individual energy and macronutrient needs. This arm serves as a comparison group to determine the specific effects of curd cheese supplementation observed in the intervention group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in HbA1c Levels

    To evaluate the effect of a curd cheese-supplemented diet on glycemic control by assessing changes in HbA1c levels from baseline to the end of the 8-week intervention.

    Measured: Baseline and after 8 weeks of intervention

Secondary outcomes (6)

  1. Change in Fasting Glucose

    To assess short-term glycemic response by measuring fasting blood glucose at baseline and after the 8-week intervention.

    Measured: Baseline and after 8 weeks

  2. Change in Lipid Profile

    To evaluate the effect of curd cheese supplementation on lipid metabolism by assessing changes in total cholesterol, LDL, HDL, and triglycerides from baseline to the end of the intervention.

    Measured: Baseline and after 8 weeks

  3. Change in Anthropometric Measures

    To evaluate changes in body mass index (BMI) from the start to the end of the intervention.

    Measured: Baseline and after 8 weeks

  4. Change in Anthropometric Measures

    To assess changes in body weight from baseline to the end of the intervention.

    Measured: Baseline and after 8 weeks

  5. Change in Anthropometric Measures

    To evaluate changes in body fat percentage from the beginning to the end of the intervention.

    Measured: Baseline and after 8 weeks

  6. Change in Anthropometric Measures

    To assess changes in waist circumference from the beginning to the end of the intervention.

    Measured: Baseline and after 8 weeks

Model description
This is a parallel-group, randomized controlled trial. Participants are randomly assigned to either the intervention group, receiving a dietary plan supplemented with curd cheese, or the control group, receiving a standard dietary plan without curd cheese. Both groups are followed for 8 weeks to assess changes in glucose and lipid parameters. The study is open-label; participants and investigators are aware of group assignments.
