The study is to evaluate the influence of an unhealthy lifestyle mainly physical inactivity and bad snacking on the development of obesity and metabolic syndrome in a Tunisian civil air navigating population. The study was conducted at the Aviation Medical Expertise Center, over a period of three years; it derived from a going on prospective study. This study focused on three groups of male subjects aged between 25 and 65 years. Their selection is based on BMI and FID criteria of metabolic syndrome. P1 (n = 35): population with metabolic syndrome only, P2 (n = 38) population with metabolic syndrome and obesity, P3 (n = 48) obese population. The three groups (P1, P2 and P3) have low regular physical activity, less than 150’/week, respectively 40 % vs.  26, 3% vs. 43, 8 % (the difference are not significant p = 0.07), only P1 have a frequency for physical activity (greater than 3 times per week) than P2 and P3 (p=0.001). But the benefits of exercise can be neutralized by a snacking based at high glycemic index or fat and simple carbohydrates foods at P1. Also P1 have the less percentage for snaking in front TV or computer than P2 and P3. Therefore P1 have a BMI <30 kg/m2, but the waist size is greater than 94 cm as much as P2 and P3. This type of practice (activity and snacking) conducted by P1 can save obesity (BMI), but not visceral obesity. P1 and P2 are older than P3 and have a function of captain, which requires more vigilance of responsibility and a lot of stress mainly than P3. These explain why P1 are not obese but have a metabolic syndrome. This study will continue on other parameters defining the lifestyle, including tobacco, alcohol consumption and diet imbalance; to specify which of these parameters leads to visceral obesity (waist size greater than 94 cm).
