Obesity puts a person at a higher risk for stroke. For maintaining a correct weight, is necessary to have a balanced diet and workout often. Talk to your doctor about which diets or activities may be right for you. If you have trouble, talk with a dietitian who can help you plan meals and snacks. To lose weight, you will have to eat fewer calories than you burn. You can check your progress by tracking your body mass index (BMI). A BMI of 25 and above is linked to high cholesterol, hypertension, and a higher risk of heart conditions that can lead to a stroke.
