If you're overweight and find that diets only work for a short time, it's likely because these diets are not sustainable in the long term. Many diets focus on quick fixes—severe calorie restriction or cutting out entire food groups—which are difficult to maintain and can lead to nutritional imbalances. This approach often results in a cycle of yo-yo dieting, where any weight lost is eventually regained. Effective weight management requires a lifestyle change that includes a change in mindset. Strategies should be realistic and flexible enough to adapt to your life, ensuring you can maintain healthy habits indefinitely.
