  • Chapter 5 DASH Your Way to Weight Loss
    Chapter 5 DASH Your Way to Weight Loss The DASH diet makes it easy to lose weight. A healthy diet, one that is based on fruits, vegetables, and other key DASH foods, will help you have satisfying meals, without overeating. And new research shows that including calcium-rich dairy foods in your diet can have special benefits for weight loss. So, DASH provides the perfect foundation for a weight loss plan. Losing weight is recommended as one of the key lifestyle changes to help manage high blood pressure. Even greater advantages can be expected when weight loss is combined with the DASH diet plan. In this chapter, you will learn how to identify your healthy weight, calculate the calories you need to reach that goal, and learn specific weight loss strategies. Research has shown that foods in the DASH diet can support weight loss. With a diet rich in fruits and vegetables, you can fill up without overdoing calories. Lean meat, fish and poultry provide satiating protein with fewer calories than higher fat meats. For example, 8 ounces of boiled shrimp has the same calories as 3 ounces of corned beef, while providing more satisfaction. Low-fat dairy foods have much fewer calories than the higher fat versions they replace. And research suggests that diets rich in dairy calcium promote weight loss, 65 especially with reducing extra fat around your waist. Being overweight is a primary risk factor for developing high blood pressure. For children and teens, extra weight is even riskier. Parents with high blood pressure, who adopt the DASH diet, help their kids significantly by providing the right foods and avoiding calorie-laden meals.
