ISSA Nutritionist Practice Exam

A diet high in trans fat is particularly linked to an increased risk of obesity and other health issues. Trans fats, which are often found in processed foods, baked goods, and fried foods, can lead to weight gain and have been shown to increase levels of bad cholesterol (LDL) while decreasing good cholesterol (HDL). This unfavorable lipid profile contributes to a higher risk of obesity-related conditions. Additionally, trans fats can affect metabolic processes in the body, promoting inflammation and insulin resistance, both of which are associated with weight gain and difficulty in losing weight. While saturated fats have also been scrutinized in the context of weight gain, trans fats have a more direct and detrimental impact on health outcomes related to obesity. Monounsaturated and polyunsaturated fats, on the other hand, are considered healthier dietary fats and can even promote weight loss when consumed in moderation as part of a balanced diet. Thus, while both saturated and trans fats can contribute to obesity, trans fats have a clearer and stronger association with weight gain and metabolic health issues.
