1- Drink a gallon of water. 

Due to the stomach having to warm the water and the energy used to eliminate waste from the kidneys, metabolism increases temporary.

2- Eat fruits and vegetables such as asparagus, grapefruit, spinach, and broccoli;  they are high in fiber and are non- starchy; this will  increase your metabolism and sustain your energy throughout the morning. Asparagus and grapefruit are diuretics as they help flush out water from the body.

3- Limit sodium intake as too much sodium in your body causes it to hold onto water; putting more stress on your heart.

4- Hit the treadmill or elliptical for at least 30 minutes.
