Of the 896 who participated, 78.7% were women, 20.6% were men, and 0.7% classified themselves as others. Regarding the generations, 11.5% belonged to Generation Z, 75.6% belonged to the Millennials, 11.4% belonged to Generation X, and 1.6% belonged to the Boomers. A total of 93.5% of the sample did not smoke, 2.3% used to smoke, and 4.1% used to smoke occasionally. Regarding the academic degree attained, 3.7% were high school graduates, 6.1% had some college credit, 0.6% had technical training, 3.2% had an associate degree, 43.2% had a bachelor's degree, 15.1% possessed a master's degree, and 28.1% possessed a doctorate. The majority of the participants (52.3%) regularly consulted Instagram for less than one year, 17.8% regularly consulted Instagram for between 1 and 2.5 years, and 29.9% had more than 2.5 years. They spent a median of 2 h per week (Q1: 1-Q3: 3) on Instagram looking over nutrition or physical activity. In relation to BMI, the median was 24.0 (Q1: 21.8-Q3: 27.2). The median of the total minutes per week performing vigorous physical activity was 240.0 (Q1: 120.0-Q3: 360.0), and performing moderate physical activity was 180.0 (Q1: 90.0-Q3: 360.0). The median of the minutes per week spent walking was 360.0 (Q1: 140.0-Q3: 840.0), and the median of the time spent sitting (hours per day) was 5.0 (Q1: 4.0-Q3: 8.0). Any meal tracker platform to record food intake over the last month was used by 34.2% (\(n=306\)) of the sample (Table 1). The associations between gender, generation, smoking habits, academic degree, time on Instagram, BMI, hours per week on Instagram looking over nutrition or physical activity, vigorous physical activity, moderate physical activity, time spent walking, and time spent sitting, and the variable usage of any meal tracker platform to record food intake can be seen in Table 1. Gender, academic degree, BMI, hours per week on Instagram looking over nutrition or physical activity, and minutes per week of vigorous physical activity showed a significant dependency on the usage of any meal tracker platform to record food intake. The percentage of women and the percentage of participants with a doctorate were significantly higher in the group that used any meal tracker platform than in the group that did not. Of the participants who had tracked their food intake, 85.3% were women, and 33.3% had a doctorate. The participants who used any meal tracker platform had higher BMIs, invested more hours a week on Instagram looking over nutrition or physical activity, and performed more vigorous physical activity. They had a median BMI of 24.9, invested a median of 2 h a week on Instagram looking over nutrition or physical activity, and performed a median of 240.0 min a week of vigorous exercise. \begin{table}
