Nutrition
Your nutritional needs will vary depending upon your health and fitness goals. If your aim is to lose body fat and body weight, you need to become familiar with the variables that affect weight loss and body fat loss. Above all, you should realize that it's more important to lose body fat than to lose overall body weight. Losing body fat reduces your risk for coronary artery disease, while losing overall body weight doesn't necessarily reduce this risk. In other words, you shouldn't just cut your calorie intake. Instead you should reduce your intake of fatty foods and increase your physical activity level

Essential Nutrients
There are six essential nutrients that you need on a daily basis :
Water
Vitamins
Minerals
Carbohydrates
Fats
Proteins
Water is the most essential nutrient the body needs. Forty to sixty percent of your body weight is water. Muscle composition is approximately 70% water. When you exercise, your body loses water through perspiration (dehydration). It is important that you continuously drink water while you are exercising and throughout the day. Eight to ten glasses (8 fluid ounces) of water are recommended throughout the day for the average person. Your individual level of water intake relates specifically to your body weight, height and activity levels. Consult a registered dietician for specific details about your own personal consumption.
Vitamins and Minerals
Vitamins and minerals are essential to your daily diet and are found in the natural foods that we consume in our daily diet (fruits, vegetables, meats and whole grains).
Vitamins are organic compounds (natural and contain carbon) which provide energy to the body and are needed in small amounts to assist with chemical reaction within the cells. Vitamins come in two forms; fat soluble and water soluble. -Fat Soluble Vitamins (A, D, E, and K) are stored in the adipose tissue (fat tissue) and can build up high levels of toxins in the body if they are not utilized. -Water Soluble Vitamins (B, C) are excreted if your daily amount of intake is too great and can be toxic in the body if they are not utilized.
Minerals are inorganic substances (unnatural and manmade) and they regulate processes within the body. Minerals are incorporated into different structures within the body to create enzymes, hormones, skeletal bones, skeletal tissues, teeth and fluids. Calcium and phosphorus are the two most common minerals found in the body. Some of the other prevalent minerals found in the body are; iron, zinc, sodium, potassium, magnesium, fluoride, sulfur, copper, and chloride.
If mineral levels are overabundant in the body, such as sodium, they may facilitate negative effects in the body. High sodium levels may elevate blood pressure. If mineral levels are inadequate in the body, such as iron, they may facilitate negative effects in the body. Low iron levels in women can produce anemia (a deficiency in blood iron levels). Anemia can restrict oxygen and carbon dioxide removal from the cells. Low calcium levels can facilitate irregular muscle contractions, bone density loss, blood clotting and improper brain functioning.
For further in-depth information about vitamins and minerals, consult a registered dietician or your physician.
Calories
A calorie, or kilocalorie (Kcal), is a measure of heat energy. Food calories are nutrients and supply energy to the body. It is essential that you take in the recommended amount of calories per day. The calorie intake level that’s appropriate for you depends on a number of factors, including your height, weight, and gender. If you want to determine a specific figure that is, approximately how many calories you should consume in a day again, consult a registered dietician. there are three types of calories:
