Severe calorie restriction, especially if it is sustained over a long period, can have negative effects on your overall health, including your heart. Eating under 800 calories per day and running 5 miles daily for 10 days could put a significant strain on your body and may lead to various health issues, including fatigue, weakness, dizziness, and potential heart problems.
The heart is a vital organ that requires a consistent and adequate supply of nutrients and energy to function properly. If you're not providing your body with enough calories and nutrients, your heart, as well as other organs, may not receive the support they need to work efficiently.
Symptoms like feeling weak and having a bad sensation in your heart should not be ignored. It's essential to seek medical attention immediately to get a proper evaluation of your health and any potential damage. A healthcare professional can perform the necessary tests and provide appropriate advice based on your specific situation.
When you start eating more, your body will have a better chance to recover and regain its strength. However, it's essential to do so in a balanced and healthy way. Rapidly increasing your calorie intake or making drastic changes to your diet without medical supervision can also have negative consequences.
Remember, only a qualified healthcare professional can provide personalized advice based on a thorough assessment of your health. If you are experiencing concerning symptoms, please don't hesitate to seek medical attention promptly. Your well-being is essential, and it's crucial to take care of yourself properly.
