When the body is expending more energy than it is consuming (e.g. when exercising), the body's cells rely on internally stored energy sources, such as complex carbohydrates and fats, for energy. The first source to which the body turns is glycogen (by glycogenolysis). Glycogen is a complex carbohydrate, 65% of which is stored in skeletal muscles and the remainder in the liver (totaling about 2,000 kcal in the whole body). It is created from the excess of ingested macronutrients, mainly carbohydrates. When glycogen is nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat stores for energy. In this process fats, obtained from adipose tissue, or fat cells, are broken down into glycerol and fatty acids, which can be used to generate energy.[24] The primary by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled through the respiratory system.

“I lost weight by hula hooping while my son played at playgrounds. It took me about seven months. I used a weighted hula hoop about 30 minutes a day, at least four days a week. Hula hooping is a full body workout, and my son loved watching the hoop go round and round, especially when he was younger. Once I started hula hooping, I started feeling better about myself and made better food choices. I'd pack my lunch—salads with turkey or chicken—with fruits and vegetables instead of heading out for fast food every day. One of the biggest changes was to always have an easy-to-carry fruit on hand in my purse for what I call a ‘hunger emergency.' If a meeting ran long or if I got stuck at the office after hours and found myself really hungry, I'd have an apple or banana instead of hitting up the vending machine for a candy bar. Always being prepared with a healthy snack and never letting myself get desperately hungry has really helped. This has prevented me from stopping at the drive-thru on my way home from work. I've also made sure to also always have a water bottle in my purse. I used to drink soda and fruit juice all day, not realizing how easy it is to drink my daily allotment of calories. I've since purchased a wearable fitness tracker and made sure to find ways to hit the recommended 10,000 steps a day, such as walking my son in his stroller to local parks and libraries instead of driving, and parking as far away as possible from where I was going.”
Let me start by saying, HOW INSPIRING!! I am 54 years old, turning 55 in February. I just started your Instant Pot Class. I lost 100 pounds a couple years ago, but then I got hospitalized with pneumonia and pleurisy. The strong steroids sent my sugar through the roof and damaged my pancreas, so now I have diabetes. All the new medications I’m on caused me to gain back almost 50 pounds. I have rods from my neck to my tailbone and I now have fibromyalgia and neuropathy, which makes a lot of exercises, including walking for long periods or distances, quite painful. I have found Chair Zumba classes on You Tube, which I do M, W, F, and strength exercises that I do T, R, Sa. I rest on Sundays. I too, wear my Vivofit, and find it to be an inspiration.
Katie’s weight has been a challenge her entire life. But after having two boys, she reached an all-time high: 253 pounds. That was when she decided to make a change, but it didn’t happen right away. For the next three years, she dieted and bounced between losing and gaining 50 pounds. Her real weight loss journey began in 2009, when she used calorie counting and running to take off 125 pounds. Today, she writes about maintaining that loss, running, being a mother, and managing a bipolar diagnosis. Visit the blog.
