How Losing Weight Affects Your Body and Brain

Have you ever wondered why it's so easy to lose weight one week into a new diet, and after that it gets progressively harder? It isn't just your imagination. A video by Business Insider shows how your body and brain can turn against you when you're trying to eat healthy foods and shed a few pounds.

After the first week of a new diet, during which time you may shed mostly water weight, your metabolism adjusts to changes in your diet and you won't burn as many calories. Also, as you start to burn more fat, you may notice that you feel hungrier. That's because a hormone called leptin, whose function is to let your brain know you're full after finishing a meal, is in shorter supply when you lose weight. As the video points out, one study revealed that obese people who had lost 10 percent of their body weight had lower levels of leptin, which activated certain areas of the brain linked with appetite.

Not only does this make you want to eat more, but your body's attempt to bring your leptin levels back to normal may also make you crave fatty foods that are high in calories. Those who push through the temptation will start to feel the difference, though. Besides lessening the strain on blood vessels and improving overall brain function, every pound of weight lost lifts four pounds of pressure from the knee joints.

Where does all that fat go when you burn it off, though? According to one study, for every 10 pounds of fat you shed, 8.4 pounds are exhaled as CO2. The remaining 1.6 pounds are converted to water and discharged from the body as urine, feces, sweat, and other bodily fluids. So rather than "burning" fat, you're actually excreting it.

Amazon Customers Are Swearing by a $102 Mattress

Before you go out and spend hundreds—if not thousands—of dollars on a new mattress, you may want to turn to Amazon. According to Esquire, one of the most comfortable mattresses on the market isn’t from Tempur-Pedic, Casper, or IKEA. It’s a budget mattress you can buy on Amazon for as little as $102.

Linenspa's 8-inch memory foam and innerspring hybrid mattress has more than 24,000 customer reviews on Amazon, and 72 percent of those buyers gave it five stars. The springs are topped by memory foam and a quilted top layer that make it, according to one customer, a “happy medium of both firm and plush.”

Perhaps because of its cheap price point, many people write that they first purchased it for their children or their guest room, only to find that it far exceeded their comfort expectations. One reviewer who bought it for a guest room wrote that “it is honestly more comfortable than the expensive mattress we bought for our room.” Pretty impressive for a bed that costs less than some sheet sets.

Getting a good night's sleep is vital for your health and happiness, so do yourself a favor and make sure your snooze is as comfortable as possible.

The mattress starts at $102 for a twin and goes up to $200 for a king. Check it out on Amazon.

Zappos Is Now Selling Single Shoes and Mixed-Size Pairs, Making Its Offerings More Accessible

For people with differently sized feet or prosthetics, shopping for shoes is often more complicated than it has to be. Zappos is now addressing this problem with a simple fix. As CNN Business reports, shoppers can now purchase single shoes or mixed-size pairs from the online shoe retailer.

According to Zappos, customers have been requesting more accessible shoe-buying options for years. For some people with prosthetic limbs and differently sized feet, spending money on extra shoes they don't need is the only way to get the right fit. Some people with amputations and prosthetics may only need to wear one shoe from a full-priced pair.

Thanks to the new policy, these customers no longer have to overpay to get the shoes that are right for them. As of Tuesday, July 14, Zappos shoes from Nike, BILLY Footwear, Converse, PLAE, Stride Rite, and New Balance are officially available to purchase as single shoes or mixed-size pairs. The shoes range from toddler to adult sizes and are priced at $17.50 to $85.

Zappos is the latest brand to make its products accessible to a wider consumer base. For years, Target has been selling Halloween costumes for wheelchair users and adaptive clothing that's easy to remove for kids with physical disabilities.
