## 4 Discussion  
This study has examined the relationship between the usage of any meal tracker platform to record food intake and gender, generation, smoking habits, academic degree, time on Instagram, BMI, hours per week on Instagram looking over nutrition or physical activity, and physical activity in USA residents that possessed an Instagram account. It was shown that a superior percentage of women and participants with a doctorate tracked their food intake. Moreover, those participants who tracked their food intake had higher BMIs, invested more hours a week on Instagram looking over nutrition or physical activity, and performed more vigorous physical activity. Thus, our outcomes suggest that using any meal tracker platform to record food intake over the last month would not lead to a lower BMI. Any meal tracker platform to record food intake over the last month was used by 34.2% of the sample. A total of 85.3% of the participants who had tracked their food intake were women (\(p<0.001\)) and 33.3% (\(p=0.018\)) had a doctorate. It has been previously shown that women and more educated participants are likely to be better respondents to online dietary intake measurements [55], which is according to our results. Women college students have manifested as those who track calories more so than men [56; 57], and highly educated citizens were revealed to use more mobile health applications [58]. Women were shown to be better respondents to the online surveys requesting data about their health-based app use [59]. More women than men have been identified as users of apps from healthy lifestyle websites for nutrition information, weight loss, and physical activity [59]. The prevalence of smoking habits in adults in the USA was determined to be 18% in 2012, and it continues to decrease [60]. In this study, the vast majority of the sample did not smoke, and there were no differences between the group that recorded their food consumption and the one that did not; thus, we can eliminate tobacco as a factor that could influence BMIs [61]. Participants who used any meal tracker platform had higher BMIs (median: 24.9 (Q1: 22.7-Q3: 27.9), \(p<0.001\)), despite being engaged in more vigorous physical activity (median: 240.0 (Q1: 135.0-Q3: 450.0), \(p=0.007\)) and complying with the recommendations on the amount of vigorous physical activity for health benefits from the World Health Organization (more than 75 min per week) [62]. Although it has been postulated that exercise is one of the keys to maintaining a healthy weight, the amount and type of physical activity that should be performed to achieve improvements is still subject to discussion [63]. A recent review showed that exercise protocols based on high-intensity \begin{table}
