Which of the following is not a concern of a low/no carbohydrate and high protein diet?

Weight loss without nutrient deficiency is often cited as an outcome of some low or no carbohydrate high-protein diets. These diets can lead to rapid weight loss, primarily due to the reduction in caloric intake and changes in metabolism. While nutrient deficiency can be a concern for long-term adherence to any restrictive diet, many individuals may initially experience weight loss without apparent deficiency, especially when guidance is provided on maintaining balanced nutrition, such as through supplementation or careful food choices.

In contrast, the other options highlight potential concerns associated with low/no carbohydrate diets. Increased risk of cardiovascular disease can stem from high protein intake, particularly if sourced from red and processed meats, which may lead to elevated cholesterol levels. Excessive arachidonic acid levels, which can arise from a high intake of omega-6 fatty acids commonly found in certain animal products, are another concern for some individuals, potentially impacting inflammation and health. Lastly, a lack of focus on organic and clean foods can manifest in any restrictive diet, where processed foods might replace whole, nutrient-dense options, leading to long-term health issues.
