The reason we’re suggesting 45 minutes instead of the typical 30 as one of the easy ways to lose weight is that a Duke University study found that while 30 minutes of daily walking is enough to prevent weight gain in most relatively sedentary people, exercise beyond 30 minutes results in weight and fat loss. Burning an additional 300 calories a day with three miles of brisk walking (45 minutes should do it) could help you lose 30 pounds in a year without even changing how much you’re eating. Here are 20 hidden reasons your diet isn’t working.
“Starting slow and working your way up is better than overdoing it and giving up,” says Gagliardi. “I like the idea of attaching the new behavior of taking a walk to an existing behavior.” An easy way to approach it: Commit to going for a quick 10-minute walk after dinner, and slowly increase the time as you become more comfortable with daily movement.
A different way of viewing weight loss identifies the problem as not one of consuming too many calories, but rather the way the body accumulates fat after consuming carbohydrates—in particular the role of the hormone insulin. When you eat a meal, carbohydrates from the food enter your bloodstream as glucose. In order to keep your blood sugar levels in check, your body always burns off this glucose before it burns off fat from a meal.
"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."
