Final answer:
One thing all diets agree on is the necessity of balancing calorie intake with physical activity for health and weight management, which contrasts with unsustainable and unbalanced fad diets.
Step-by-step explanation:
According to Keri Wiginton, one thing all diets agree on is that to achieve weight management and overall health, a balance between calorie intake and physical activity is essential. Diets may differ in opinion on which foods to eat or avoid, but eating healthy, whole foods and engaging in regular physical activity are consistently recommended strategies for successful weight loss and health improvements. This avoids the pitfalls of fad diets which often promise rapid weight loss without the need for exercise and are not sustainable long-term. Such diets might lead to quick weight loss, mostly from water, and can be unbalanced and lacking in essential nutrients.
Furthermore, evidence-based dietary recommendations, such as those in the 2015 Dietary Guidelines for Americans, emphasize a well-rounded diet that includes a variety of vegetables, fruits, grains, low-fat dairy, and a mix of protein sources. These guidelines aim to steer people away from the lure of fad diets and towards a holistic approach to health that ties in dietary choices with wellness and active lifestyle habits.
