"Inadequate intake of calories, especially protein, causes the body to breakdown muscle tissue to meet the needs for amino acids," says Cederquist. "I have my patients focus on obtaining adequate lean protein and spreading it throughout the day." Her recommendation: focus on 100 grams per day, which breaks down into three to four ounces of protein at breakfast, lunch, and dinner, and a few ounces for snacks.
We know, you've probably heard these a thousand times. But if you can make these small swaps day-to-day, you'll spare enough calories for the treat foods you really want or to go into a calorie deficit (a.k.a. the key to weight loss). (And this is just the tip of the iceberg. We have 50 more easy ways to cut calories.) Making these simple swaps is the way to health-ify your eating style and lose weight without actually dieting. 
A 2015 study from Brown University found that you’re likely to have less belly fat if you have a high degree of “dispositional mindfulness” — where you’re naturally inclined to pay attention to your present thoughts and feelings. The researchers speculated that this kind of “everyday mindfulness” helps overcome the instinct to stock up on calories, which are not in short supply to use modern humans.
Simply take a good hard look at your diet, make a few modifications you can stick with and get your body moving. Not sure where you stand on diet? Write down everything you eat this week, then compare it to the list above and see where you could have made better choices. Don’t beat yourself up though, learning how to lose stomach fat fast is a process. Simply find areas to improve and work on them next week.
Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
