You weigh yourself on different days each week
In a Cornell University study published last year, researchers analyzed the food and weight diaries that 80 people kept for up to a year. They found that peoplesโ weight fluctuated considerably throughout the weekโmany people were heaviest on Mondays (blame decadent weekend eating) and lightest on Fridays. Keep weigh-in days consistent for a more accurate assessment.
You miscalculate your clothing
File this one under โYes, scientists have actually studied this.โ When University of North Dakota researchers weighed people naked and clothed at various times of the year, they found that men can subtract 2.5 pounds for their clothing and women can shave off around two pounds, on average.
You don’t factor in muscle gain
Youโve heard that muscle is denser than fat. In fact, it takes up only about a third as much space. If you start a strength-training routine, the number on the scale might not budge, but you could still lose inches and drop a clothing size or two.
You indulge in a high-carb or high-sodium meal
Salty foods cause your body to hoard extra water, which can temporarily pad the number on the scale. So can certain carbs. When you consume more refined carbs than your body needs, you store the excess as glycogen in your liver. Glycogen attracts water, so eating a heaping bowl of pasta can bloat you the same way a salty meal does.
