It is always worth keeping an eye on your weight. If you are at a healthy weight, it is also easier to exercise and be active. Controlling your weight, for example, helps take the strain off your heart. You can see if you are overweight by calculating your Body Mass Index (BMI). BMI is a rough guideline to evaluate a person's weight. If you have a BMI over 30, losing weight is an important way to improve your health and help your heart.

Eat a balanced diet and be aware of what you are eating – not too much and not too much fat or salt. When you cook, opt for plant-based fats and oils because they contain unsaturated fatty acids. It is better to eat fish with its omega-3 fatty acids than meat, and to opt for low-fat dairy products and vegetarian dishes. Plenty of fresh fruit, vegetables and whole grains will help you get the fiber and vitamins you need. If you are suffering from heart failure, check first how much liquid you can drink a day. Usually one to two liters a day are allowed.

Alcohol and nicotine can contribute to and worsen heart disease. It is ideal to give up smoking altogether and only drink alcohol in moderation, and after eating.
