Wrong. Diet and exercise is the healthiest formula to follow for attaining your desired weight loss. Many people are put off by the recommendation that a safe, healthy diet only results in a loss of one or two pounds per week. Think of it this way: If you want to lose 15 pounds, you need fewer than four months of consistent, safe dieting and regular physical activity to attain your goal.
Take time to plan your weekly menu, making sure to create a diet rich in fruits, veggies, whole grains and lean meats. For best results, swear off nutritionally deficient foods like white bread and rice, sugar and processed foods that contain lots of sodium and saturated fat. Bear in mind that enough exercise will actually help you build muscle mass, so even if the needle on the scale doesn't move much, you'll notice the change in your body by the way your clothes fit.
