Common pitfalls in dieting and weight loss include unrealistic goals, extreme calorie restriction, and reliance on fad diets. Many individuals may set unattainable targets, leading to frustration and disappointment. Extreme calorie cutting often results in nutritional deficiencies and can negatively affect metabolism. Additionally, relying on fad diets can create a cycle of quick fixes rather than promoting sustainable lifestyle changes. A lack of support and accountability can also hinder progress. Instead, adopting a balanced approach that includes whole foods and regular physical activity is essential for long-term success.
