Fathi, Y., Faghih, S., Zibaeenezhad, M. J., & Tabatabaei, S. H. (2016, February). Kefir drink leads to a similar weight loss, compared with milk, in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women: A randomized controlled trial.

Want a flatter stomach? Look in your glass—milk and soda are two major causes of tummy inflation. Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy, which means that your glass of warm milk before bed may be the reason you wake up with too-tight pajamas. And when it comes to soda, both regular and diet are belly busters both from the sweeteners used and the carbonation. Try eliminating these from your diet and see if it helps flatten your tummy.
A 2014 Harvard study found that men who did twenty minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, and other studies have shown similar levels of success when guys hit the gym to cut down on fat. The implication: Guys can cut belly fat most efficiently with weight training.
Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.
Some diet plans, such as the MIND diet and the DASH diet, are meant to focus on certain areas of health — and weight loss may be a bonus. Others are created with weight loss as a primary goal. “It is important to remember that we are all very unique individuals,” says Kyle. “We all have different states of health and different lifestyles, which could affect what diet plan is best for us. That means that you should not be considering what is working for your friends or family members — and instead should pay attention to what works for you individually.”
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
“Every morning I drink a cup of warm water with half a lemon squeezed into it, a teaspoon of apple cider vinegar, and a dash of cayenne pepper,” says Michelle Keough. This helps her start her day off on a healthy note while getting her hydrated after a long night. This trick, combined with eating meals built around protein and veggies, helped her lose 20 pounds and keep it off.
Stress skyrockets your levels of cortisol, often called “the belly fat” hormone because it signals to the body to store fat around your waist. Add the daily stressors of living our modern lifestyle and you can see how cortisol can be constantly coursing through your veins. This perma-stress mode isn’t good for a lot of healthy reasons, your tummy being just one of them, so it’s important to take time every day to de-stress. Yoga, meditation, walking, journaling, doing a hands-on hobby, or playing a musical instrument are all great time-tested methods. (Hint: Know what isn’t? Watching television. The boob tube actually increases your levels of cortisol!)
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
People who get enough sleep tend to weigh less than those who don't. Additionally, researchers found that well-rested dieters lost more fat than those who were sleep deprived, who lost more muscle. "Whenever I don't sleep enough, I'm ravenous the next day," says Weil. To keep her hunger in check and help her maintain her slim figure, she tries to get at least 8 hours of sleep every night.
When Tufts University researchers studied the waistlines and diets of 459 people, they found that even in men of similar age and activity level, those who ate white bread frequently weighed more than those who didn’t. “The calories from white bread and refined grains just seem to settle at the waistline more than calories from other foods,” says Katherine Tucker, Ph.D., the study author.
All meals are important, but breakfast is what helps you start your day on the right track. The best, heartiest breakfasts are ones that will fill you up, keep you satisfied, and stave off cravings later in the day. Aim to eat anywhere between 400 and 500 calories for your morning meal, and make sure you're including a source of lean protein plus filling fat (e.g., eggs, beans, unsweetened Greek yogurt, nuts, or nut butters) and fiber (veggies, fruit, or 100% whole grains). Starting your day with a blood sugar-stabilizing blend of nutrients will help you slim down without sacrifice.
Carbohydrates are considered to be the body's main source of energy and are quickly utilized by the brain and muscles. Carbs come in two forms: simple & complex. Processed and refined sugars are simple carbs, which are digested and absorbed quickly. Complex carbs pack in more nutrients and are digested more slowly, which helps stabilize blood sugar levels.
