1. For the Control Diet, a medical nutrition therapy with calorie and fat content was prepared to ensure weight loss of individuals without considering the glycemic index.
2. The aim of this diet is to achieve weight loss, but not to focus on the content of carbohydrates. 3) In the macro element distribution of the CD, 50-55% carbohydrates, 10-15% protein and 20-25% fat distribution Other name (CD Group)

1. Participants who came to the hospital for control and were interested in the study contacted the study researchers and eligibility was determined through face-to-face interviews. Potential participants were invited to a screening visit to verify eligibility.
2. The LGID program was initiated as an outpatient treatment in patients who applied to a dietitian. 3) Medium and high GI carbohydrates (GI > 55) were excluded from the diet and only low GI (GI < 50) foodstuffs were allowed. 4) A list of low glycemic index foods were given to the patients. In addition, a list of foods to avoid (medium and high glycemic index) is provided.

Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index was obtained by the following formula: fasting glucose (mg/dl/18) x fasting insulin (U/mL)/22.5.

A HOMA-IR index >2.5 is in favor of Insulin Resistance (IR).

Blood samples were collected after an overnight fast by using 10 mL plain tubes. Lipid profile was measured by using Cholesterol Kits and total cholesterol levels were measured using the sum of the LDL and HDL plus one-fifth of triglyceride levels.

Fasting plasma glucose (FPG) levels were determined by taking a blood sample from participants who have fasted for at least 8 hours, Fasting glucose is between 75-95 mg/dL (4.2-5.3 mmol/L).

Fasting insulin is between 18-48 pmol/L.

Body weight was measured in kilograms.

Body muscle ratio as assessed by bioelectrical impedance analysis -- whole body composition was evaluated.

The body image scale (BIS) includes 10 items, and was developed to briefly and comprehensively assess the affective (e.g., feeling self-conscious), behavioral (e.g., difficulty in looking at the naked body), and cognitive (e.g., satisfaction with appearance) aspects of body image in patients. It is a 4-point scale (0 = not at all and 3 = very much), and the final score is the sum of scores for 10 items, ranging from 0 to 30, with a lower score representing a better body image.
