To apply this concept to foods like sandwiches, scientists used to set food on fire (really!) and then gauge how well the flaming sample warmed a water bath. The warmer the water, the more calories the food contained. (Today, a food’s calorie count is estimated from its carbohydrate, protein, and fat content.) In the calorie’s leap to nutrition, its definition evolved. The calorie we now see cited on nutrition labels is the amount of heat required to raise 1 kilogram of water by 1 degree Celsius.

Here’s the problem: Your body isn’t a steam engine. Instead of heat, it runs on chemical energy, fueled by the oxidation of carbohydrates, fat, and protein that occurs in your cells’ mitochondria. “You could say mitochondria are like small power plants,” says Maciej Buchowski, Ph.D., a research professor of medicine at Vanderbilt University medical center. “Instead of one central plant, you have several billion, so it’s more efficient.”

So what should be considered in terms of weight loss? For starters, nutrition. A nutrition-focused food choice is more beneficial than a calorie-focused food choice. For instance, choosing a high-fiber food will benefit you more than another that may be lower in calories because more than likely the high-fiber food will keep you full longer than a food choice low in calories. With the low-calorie food choice, you will end up eating again sooner because you are hungry, thus consuming extra calories in order to fill yourself up. Another is that you begin to identify foods high in calories and/or that have little to no nutritional value that you can eliminate from your diet. Also, you can reduce your portions as well as switch to low-calorie alternatives. A cup of raw broccoli contains only 31 calories, while the same amount of chocolate ice cream has close to 285.

Finally, increasing your activity level could also help. Becoming more active can greatly benefit you by burning calories. Some foods require more energy than others to digest and metabolize, particularly high-fiber, protein foods. You could save about 12 to 15 calories per day by merely walking for about 4 minutes. Most experts agree that its easier to exercise than to cut the same number of calories that the exercise burns off. Bottom line, it’s best to focus less on eating from a measuring cup or scale and focus more on what you’re eating, portion control and activity levels. Calories count but they are far from being the whole picture. Besides that, counting calories is way too complicated. Most times we either underestimate or overestimate the calories in our meals. So go ahead and take the easy route and start making calories count!

Beginning a fitness program including walking is dirt cheap. You just need a great pair of shoes, a comfortable companion and away you go. You should probably check with you doctor if you are not in the best shape or if you added a few years since your last workout.

Begin by taking slow, no need to bust out the gate. Think of yourself as the tortoise, you know the end goal and allow yourself time to get there. Start out at a normal walking pace for the first five minutes, this will allow for the muscles and joints to warm up properly. Once you have the blood flowing, I suggest quickening the pace for five minutes. Keep this schedule for a week, if it seems easy for you, go ahead and add five minutes. Please make sure you are cooling down properly, it does not matter what age you have attained, proper cool down and stretching are important.

Stay focused on proper form when walking: * Try and stay erect as possible, i.e. good posture. * Do not let your back arch. * Try not to lean, it places stress on the muscles in the back. * Stay focused on the path in front of you. No need to look down (unless a lace becomes untied). * Work your abs when you walk. Go ahead and contract them and let them relax, as long as it does not interfere with your breathing. Maintain your fluids, try and keep yourself hydrated. You can use a Camelback if carrying a bottle is uncomfortable. You can find Camelbacks at outdoor and cycling shops. They basically carry water in a comfortable style back pack. Keeping hydrated is essential. Most people do not realize they are dehydrated. A good indicator is found in your urine. If it’s dark, you are probably dehydrated, the cleared the better.

Remember you must warm up properly and cool down properly. Each walking workout needs to incorporate proper stretching. Do not stretch any muscle until it has had a chance to warm up and loosen. After your workout, please re stretch to avoid muscle tightness. It will help you with your calories burned while walking. Try these five tips to help keep you motivated when trying to burn calories while walking. 1. Find a comfortable partner and make sure you motivate each other. Workouts can become dull and routine. It’s always nice to have someone to talk to and lean on when feeling unmotivated. 2. Enter a race or a charity event like Making Strides for Breast Cancer; it will make all you efforts seem really worth while for calories burned while walking. 3. Keep a record of your walks and record how far and how fast you walked, this will help you maintain and up you fitness levels. Remember calories burned while walking will help you trim fat from your body and give your cardiovascular health a boost. Walking is great exercise, plus it’s a fun way to lose weight
