To lose fat you have to increase your lean body mass. This is done by optimizing the nutritional composition of the food you eat. That being said, you need to increase the amount of favorable protein sources you consume and decrease the amount of high glycemic carbohydrates (sugar and starches) you eat.
Here are some examples of what to eat. Favorable proteins consist of organic lean beef, poultry and fish. Low glycemic carbohydrates consist of leafy green vegetables, organic whole grain sprouted bread (such as the Food for Life brand - Ezekiel 4:9) and fruit.
