Endurance Training Helps Cells Release Fat
Losing body fat and keeping it off is extremely difficult and only about five percent of dieters are successful after a year. Many studies suggest that the only way you can lose fat permanently is to diet and exercise at the same time. People who only diet usually gain back all the weight they lost and then some. Part of the problem is that fat cells in obese people like to hold onto their fat. French researchers discovered that endurance training made fat cells more responsive to the hormone adrenaline, which made the fat cells release fat into the blood more easily.

Potassium Accurate Measure of Nutritional Health
Canadian researchers found the urinary potassium is a good measure of the quality of the diet. People with the highest levels of potassium were most likely to eat a well-balanced diet that met the United States Department of Agriculture Nutritional Guidelines. These people were also leaner and had lower blood pressures and resting heart rates. Low potassium levels suggests a diet high in fat and low in fruits and vegetables. Urinary potassium is a simple test that doctors can do in the office or patients can do at home. Good food sources of potassium include sweet potatoes, tomato paste, beets, white beans, yogurt, clams, prune juice, carrots, bananas, soybeans, halibut, and tomatoes.
