My app informed me once again that I made two marathons this month of 2016 - accumulated, of course :-) - 84K this December.
Today at around 9 am, I finished another 10K, with 82 meters elevation gain, burning 460 calories. It was a cold morning, I didn't want to stop moving in order to film a vlog.
I stopped twice though. The first time after the first kilometer to jump and to make some exercises, including grand battement. The second time after the 8th, to stretch and relax.
I try to run once or twice a week, but if I have an opportunity, I allow myself to run 3-4 times, and if I want more, I go for a long walk, combining it either with listening audio books, or to gather some B-roll footage or photographs with a camera.
I borrow the books through another app in a local library, and usually manage to find good titles in the nonfiction section, preferably on business or investment.
For many years I used to listen to music on my runs, but now I reserve my best playlists for dancing and other exercises.
I added a few recent scenes from my life to the visuals of the today's run and put together this 27th vlog.
My next week will be quite busy, so this might be a good chance for me to wish you a happy switch to the new year.
Food energy is chemical energy that animals derive from their food and molecular oxygen through the process of cellular respiration. Humans and other animals need a minimum intake of food energy to sustain their metabolism and to drive their muscles.
Organisms derive food energy from carbohydrates, fats and proteins as well as from organic acids, polyols, and ethanol present in the diet. Some diet components that provide little or no food energy, such as water, minerals, vitamins, cholesterol, and fiber, may still be necessary to health and survival for other reasons.
Using the International System of Units, researchers measure energy in joules (J) or in its multiples; the kilojoule (kJ) is most often used for food-related quantities. An older metric system unit of energy, still widely used in food-related contexts, is the "food calorie" or kilocalorie (kcal or Cal), equal to 4.184 kilojoules.
<>Fats and ethanol have the greatest amount of food energy per mass, 37 and 29 kJ/g (8.8 and 6.9 kcal/g), respectively. Proteins and most carbohydrates have about 17 kJ/g (4.1 kcal/g).
Conventional food energy is based on heats of combustion in a bomb calorimeter and corrections that take into consideration the efficiency of digestion and absorption and the production of urine.
