"Much may be done in those little shreds and patches of time which every day produces, and which most men throw away"

WEBSITE: http://www.dailyherald.com/story/?id=273757 Work out and feel great by doing something good for others! Volunteering will not only give back, but can increase your physical fitness! Around 340 calories to play wait kids for an hour...talk about two birds with one stone :)
Basal Metabolic Rate is what your body needs to function in a completely rested state. Just having your heart pumping and organs working, it takes energy. This energy comes from the food you eat. In order to figure out your specific BMR you can use this formula:
Women: 655+(4.35xweight in pounds)+(4.7Xheight in inches)-(4.7Xage)
Men: 66+(6.23Xweight)+(12.7Xheight)-(6.8Xage)
(When trying to lose weight, do not go more than 500 calories below this! That is too much and not a healthy way to lose weight!! As a key, no woman should never go below 1200 and man 1500!)
This is an estimate of what it would take if you had a completely sedentary lifestyle. By increasing activity, your daily needs are increased so that you have sufficient energy. Not adding enough calories forces your body to reach into fat stores for energy...which is not as good as it sounds. This can lead to "bonking", meaning fatigue, light-headedness, loss of coordination and weakness. Not good things when trying to work out! This symptoms mean you are asking for more than your body can provide, and most likely have a dip in your blood sugar level.
This does not mean you should wait for the dipping feeling to reach for an energy bar. You must plan ahead so that your body is getting the nutrition and energy it needs for everything you throw at it.
During strenuous exercise it is vital that you give the body ample energy. Because the goal of this activity is to build muscle (whether it is the heart muscle in cardio or body muscles in strength training) but when you finish exercising and don't give your body a replenishing supply you actually eat away at the existing muscle. It effectively reverses the efforts you have put in to work these muscles.
There is a very scientific way in which energy is formed and released within the body but I am not at all a scientist so I will try to explain this in the easy way!
There are 3 different systems in the body that work together to create the energy you need in a workout. The contribution of each system depends on the intensity and duration of your exercise.
ATP-CP System-short burst energy system, think a 6-second full out sprint here. It requires no oxygen and is part of an anaerobic support system. We have a very limited amount of this creatine phosphate (CP) in our muscles, so our supply is used up very quickly.
Anaerobic System-this system works longer, around 90 second or pushing. It breaks down glucose for energy without the use of oxygen. Unfortunately, it also produces lactic acid that can cause athletes to "hit the wall" but unless you are out doing some crazy things you shouldn't worry about that!
Aerobic System-This is our endurance training, where we teach out bodies to keep going for longer periods of time. This system slows down the use of glucose for energy. It uses fat for energy, which teaches our muscles to use fat efficiently.
OK so what does that all mean in terms of food energy? Clearly, it is vital that these systems have a place to get the energy to produce effective workouts. Energy comes from carbohydrates, protein and fat. The glucose needed to burn in these workouts comes from the breakdown of carbohydrates, which is why carbs are vital for fitness!
Specific needs vary from person to person, and increasing intensity needs to result in an increase in intake of these nutrients. In moderate to high-intensity exercise, your body will gradually begin to burn more fat and less glucose for energy.
It is no secret that you are able to work out longer and harder and you get more fit. That is because your body becomes trained to burn fat more effectively (well one reason at least). So you begin to be able to train longer without fatigue and burn more calories.
So how can you get the most energy from your workout while remaining safe?
1. Stay hydrated! I can't stress enough the importance of drinking water, especially when increasing your exercise.
2. Be proactive with food supply. Getting proper nutrients at every meal will keep your energy levels high. Remember it takes time for this energy to be released so don't wait until you feel fatigued to grab that apple!
3. When planning on a long, hard workout, increase your intake of carbohydrates. We all know the marathon runners carb-loading secret!
4. Don't eat right before you exercise, your digestive system will be working against your muscles as they compete for energy. Large meals should be 3-4 hours before working out, and smaller meals 2-3 hours. Do what works best for you, I know some people like a small snack right before or even during their physical activity.
5. Make sure you provide the body with protein prior to a long workout, and replenish the body with carbs following your exercise.
6. Nature is the best source of energy. You don't need processed energy drinks, bars and and gels. Instead take from the earth and fuel up on bananas, dried fruits, nuts, yogurt, granola, grapes, water, and many of the natural foods God created for us!
7. If supplements are the route you take, make sure you research them and know what you are putting in your body. Just because they are in the nutrition aisle does not mean they are good for you!!
8. Listen to your body. Your body is the best indicator of what you need for a healthy lifestyle. It will let you know when it needs food, and what kind of foods it needs.
So eat and be fit :)
