A fat-burning superfood, grapefruit contains a compound that can lower the fat-storage hormone insulin, which in turn can lead to weight loss. In fact, eating half a grapefruit before each meal could help you lose up to a pound a week—even if you don't change anything else about your diet. Because grapefruits are 90% water, which fills you up, they also act as a natural appetite suppressant.

^{A study in the journal Cell  found that our gut microbes are just as affected by changes to our circadian clock as we are. When we shift our sleep-wake cycles, our gut flora changes, and beneficial bacteria are replaced by the growth of bacteria that have been linked to obesity and metabolic disease. When traveling across different time zones, it’s important you travel armed with healthy, fiber-rich snacks your gut will love.}
Do you consider products from specialty supermarkets to be healthier than those from other grocery stores? Or do you think that dishes from organic restaurants are all waistline-friendly? If you answered yes to either of these questions, you could be derailing your weight loss efforts. When people guess the number of calories in a sandwich coming from a “healthy” restaurant, they estimate that it has, on average, 35 percent fewer calories than they do when it comes from an “unhealthy” restaurant, according to a study in the Journal of Consumer Research. Remember that the next time you reach for that package of Whole Foods’ Organic Fruit & Nut Granola. One cup of this seemingly healthy snack contains almost 500 calories. Yikes! To stay on track at the grocery store, check out these best supermarket shopping tips ever.
As it turns out, almonds aren’t the only superstar nuts around. Studies have shown pistachios aren’t bad to snack on either. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for three months. One group was given 220-calories of pretzels as an afternoon snack, while the other sect munched on 240-calories worth of pistachios. About a month into the study, the pistachio group had reduced their BMI by a point and improved their cholesterol and triglyceride levels, while the pretzel-eaters stayed the same.
Kimchi is a spicy Korean condiment that's made with fermented cabbage and is a great source of vitamins A, B, and C. Because it's fermented (like sauerkraut), kimchi contains tons of those good probiotics that aid the body in digestion. A recent study in the Proceedings of the National Academy of Science found that maintaining healthy bacteria in your gut can improve gut lining, which in turn could help reduce fat mass and inflammation.
Big-box stores such as Costco or Sam’s Club are great money-savers, but frequenting them to buy groceries can be bad news for your fitness goals. That’s because a 2015 study in the journal Appetite  found that the larger the bottle, bag, or box the food comes in, the larger we think the serving size should be. To come to that conclusion, researchers surveyed more than thirteen thousand people and found that when confronted with larger packages of cola, chips, chocolate, or lasagna, the shoppers tended to want to serve themselves larger portions.
Even if you’re trying to reduce your eating window, you shouldn’t go to sleep starving. In fact, going to bed with a rumbling stomach can make it more difficult to fall asleep and subsequently leave you feeling ravenous the next day. And get this: Eating the right type of bedtime snack can actually boost your metabolism and aid weight loss, registered dietitian Cassie Bjork explained. “The right snack can help keep blood sugar stable so the fat-burning hormone glucagon can do its job. I suggest pairing a natural carb with a healthy fat. Apple slices and almond butter, berries with heavy cream and carrots with guacamole all fit the bill.”
“Repetition builds rhythm. Be boring. Most successful losers have just a couple of go-to breakfasts or snacks,” says registered dietitian Lauren Slayton. “Make an effort to pinpoint these for yourself. ‘Hmm, I’m starving what should I have?’ doesn’t often end well. You can change the rotation every few weeks, but pre-set meals or workouts on certain days will help tremendously.”

A 2012 CDC study found that the average adult consumes about 100 calories worth of alcohol daily, but favoring a glass of wine instead of beer or sugary cocktails can drastically reduce that figure and make your waistline slimmer. In addition to having fewer calories than most alcoholic beverages, red wine, in particular, is a good source of those waist-shrinking flavonoids that are also found in red fruits. Resveratrol, a particular flavonoid found in red wine, is believed to have heart health benefits because it helps prevent blood vessel damage and reduces your ‘bad cholesterol.’ Just remember to imbibe in moderation.

Finally, after all, the discussion, and after getting a clear idea on how to lose weight quickly and safely, you should keep in mind that success does not come to you without hard work.If you follow the correct steps, you will obviously reach the topmost floor. So, work hard and get yourself motivated by watching some weight transformation videos on the internet.

While no one food is a magic bullet for weight loss, there are certain foods that can help you achieve your weight-loss goals. Most of the foods included as part of a weight-loss diet have a few things in common: they're high in fiber (which helps keep you feeling fuller longer) and have a low energy density-meaning that you can eat a decent-sized portion without overdoing it on calories. Include the following weight-loss foods as part of a healthy overall diet, and you may find it's easier to achieve your weight-loss goals.
