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. The primary by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled through the respiratory system.
About: Christie literally just got going (her first post was in March). But she didn’t waste any time putting it all out there. Her goal is to lose more than 100 pounds and beat a lifelong struggle with depression and anxiety. Her openness caught our attention immediately, and we can’t wait to follow along with her as she takes each and every step.
About: Lisa hails from the United Kingdom — a long way from the U.S., but with a touching story of strength that is impossible to ignore. Lisa suffers from Chronic Fatigue, a debilitating condition that’s slowed her down significantly in life, and one that she’s also managed to fight back from. Lisa started her blog about a year ago as a way to lose weight in the hope that it would help improve her disease — her fight is definitely an inspirational one to follow.
Open up a big bag of baby carrots and dip them into your freshly made no-oil-added, no-salt-added hummus. Simply whip up in your food processor a can of no-salt-added chickpeas/garbanzo beans, fresh tomatoes, lemon juice, garlic, a jalapeno pepper (if you like your hummus hot and spicy), and fresh herbs like cilantro and dill. Add a little water, if necessary, until the desired consistency is achieved.
WH Verdict: While it’s unlikely to be popular with those who’ve chosen a plant-based lifestyle for ethical reasons, the principal of eating real, whole food is sound. And combining two ways of eating certainly makes it easier to get enough protein and vital nutrients. But it’s still pretty restrictive, so consult a nutrition professional to make sure you aren’t at risk of nutritional deficiencies.
