That’s bad news, but emerging evidence shows that there are plenty of compelling reasons to start moving at any age and even if you’re ill or pregnant. Indeed, scientists are learning that exercise is, actually, medicine. “There is no pill that comes close to what exercise can do,” says Claude Bouchard, director of the human genomics laboratory at Pennington Biomedical Research Center in Louisiana. “And if there was one, it would be extremely expensive.”
After ingestion, carbs are converted into glucose and burned for fuel or stored as glycogen in the liver and muscles for later use. According to the European Journal of Applied Physiology, each gram of glycogen stored in the muscles holds at least 3 grams of water. The more carbs you eat, the more water you'll hold, which can make your arms look fuller.
This is a particularly cool one. Neuroscientists used to believe the brain was the only organ incapable of growing new cells—which partly makes sense, since we need our brains to be relatively stable over time, to keep our memories intact and to keep us us. But in recent years, it’s become clear that the brain, too, can grow new neurons, in a process called neurogenesis. And what seems to spur the growth of new neurons, perhaps above other activities, is aerobic exercise. (Other things, like meditation and antidepressant medication, have also been shown to trigger brain new cell growth.) The area of the brain that seems most capable of growing new cells is the hippocampus, the seat of learning and memory. It's also the area that’s known to “shrink” in depression, and particularly in dementia—so the fact that we may have some control over its health is exciting.
I am SO happy that you are here! This site was launched with the same intentions that drove me to write The Body Book & The Longevity Book: to merge information with action, so that we will all know how to take care of this machine that we call our bodies, from eating to moving to getting enough sleep to everything else that impacts our health and happiness. If you want to live better and feel better, you’ve got to get real, get knowledgeable and get on it. I know you can do it!
Not feeling up to heavy lifting? Try doing more reps at a lower weight instead and you’ll be kissing that arm fat goodbye in no time. Researchers at Canada’s McMaster University studied a group of 20-something men over a 12-week period, with half the study subjects lifting heavy weight and doing low reps, and another group lifting lighter weights for higher reps. The Journal of Applied Physiology study found that both groups increased their strength and muscle size by approximately the same amount, so if you’re relatively new to lifting or don’t feel up to hitting the heavy weights just yet, don’t worry; lighter lifts will still help you ditch the fat while gaining muscle tone.
Protein and fat loss go hand in hand. This nutrient supports muscle growth and raises your metabolism, making it easier to slim down. It also promotes satiety and reduces hunger, so you'll eat less without even realizing it. The American Journal of Clinical Nutrition states that high-protein diets can positively impact appetite, cardiometabolic risk factors, body weight and other factors.
