We’ve already established that friends and family play a key role in motivating you to get in shape and maintain a healthy lifestyle, but it’s also crucial for you to be your own driving force. Luckily, research has shown that doesn’t need to require a tremendous amount of effort. According to a 2015 study in the Journal of Marketing Research , subtle, even subliminal, messages may be more effective at helping us stick to a healthy eating regimen than ongoing, conscious focus. The research showed that people who receive reinforcing notes urging them to eat healthily were more likely to make smarter choices than those who tried to keep their goals top of mind at all times, so grab some Post-Its and start crafting motivational messages!
However, if a HIIT workout or piling on muscle mass seems too daunting, simply move for two-ish minutes to whittle your waistline. Why, you ask? Research printed in the journal Physiological Reports showed that people who did five 30-second bursts of max-effort cycling, followed by four minutes of rest, burned 200 extra calories that day. If you incorporate this technique into your workout routine just a few times per month, you can burn thousands of additional calories per year.

Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. Plus, it'll help you relax post-meal so you won't be tempted by stress-induced grazing that can rack up calories.

A great source of calcium and important cancer-fighting compounds, broccoli also has loads of filling fiber and will set you back only 30 calories per serving. If eating this cruciferous veggie makes you bloat, try steaming it first, which makes it easier to digest while still preserving the cancer-fighting ingredients that could be lost when you boil or cook it in the microwave.
“There are so many amazing properties in tea and so many healthy foods that require hot water,” Emmy-award winning and author of The 7-Day Flat-Belly Tea Cleanse, Kelly Choi says. “But I’ll swap in hot green tea instead of water for things like oatmeal and quinoa. I’ve seen so many people benefit from my tea cleanse that it inspired me to keep the tea flowing whenever I can!”
Since tomatoes can be grown indoors, they never really go out of season, making them a reliable weight loss staple to add to your diet. The tasty fruits have a high water content that will help keep you hydrated, and they’re also low in calories. What’s more? A study published in Nutrition Journal  found that eight weeks of tomato juice consumption helps the body burn about an additional 100 calories per day—that adds up to around 3,000 calories a month!

Leaving the comforts of your gym can be difficult, but outdoor workouts have their own unique set of benefits. Research has shown that breaking a sweat outdoors may be more beneficial than burning calories inside. According to a study published in Environmental Science and Technology , exercising in a natural environment outdoors may improve energy levels and decrease stress more than working out indoors can.

Fill at least half of your lunch and dinner plate with vegetables. Vegetables are nutrient-dense, high in satiating fiber, and low in calories, making them ideal weight loss tools, says registered dietitian Danielle Omar. “By eating the veggie half of your plate before anything else, you will take the edge off your hunger, eat less overall calories, and still feel full and satisfied. Keep eating this way and the pounds will painlessly melt away.”

Yes, you can eat dark chocolate to lose weight. A study among women with normal weight obesity (or “skinny fat syndrome”) who ate a Mediterranean diet that included two servings of dark chocolate per day showed a substantial reduction in waist size than when on a cocoa-free meal plan. Researchers attribute dark chocolate’s weight loss abilities to flavonoids, heart-healthy compounds in the sweet treat that the scientists at Harvard say can reduce the risk of diabetes, heart disease, and mortality. Like nuts, dark chocolate has also been found to induce satiety. When reaching for chocolate, just make sure you choose a bar with at least 70 percent cacao. Anything less contains more belly-bloating sugar and a significantly reduced flavonoid content.
High-calorie drinks. Sweetened beverages are full of calories. Drink water this week and avoid all alcohol (wine, beer, and cocktails), juice, sports drinks, sweetened teas, flavored coffee drinks, soda, and commercially flavored water (such as vitamin waters). You can also make flavored water with fresh lemon juice or other fruit if you don't like plain water. Stay hydrated, but avoid drinks that cause weight gain via empty (non-nutritive) calories.

Another condiment worth utilizing in place of sugary dressings and marinades is apple cider vinegar. According to a study published in Bioscience, Biotechnology, & Biochemistry, consuming apple cider vinegar each day can lead to weight loss, reduced belly fat, waist circumference, and lower blood triglycerides. More specifically, the study of obese Japanese participants found that those who consumed 1 tablespoon of ACV over a three month period lost 2.6 pounds, and those who consumed 2 tablespoons lost 3.7 pounds in the same time frame. Go ahead and toss a tablespoon or two of this calorie, fat, and sugar-free stuff in your next salad dressing, sauce, or smoothie.

3. Be realistic about which habits need to go. "When I was heavy, I'd eat French fries every single day, plus carbs at almost every meal—like a sandwich for lunch or bread with pasta for dinner. A diet so heavy in fried food and carbs just isn't conducive to weight loss. To lose the weight, I went from three large meals a day to six small meals, mostly made of fresh vegetable salads with lean meats and nuts. And no more bread!"

Friends are helpful not only because they can double as workout buddies or help hold you accountable for appropriate diet and exercise, but also because they’re a surefire way to combat gut-growing feelings of loneliness. A study in the journal Hormones and Behavior  found that those who feel lonely experience greater circulating levels of the appetite-stimulating hormone ghrelin after they eat, causing them to feel hungrier sooner. Over time, folks who are perennially lonely simply take in more calories than those with stronger social support networks, so be sure to fit time with pals into your busy schedule.

Going long periods of time without food does double-duty harm on our healthy eating efforts by both slowing down your metabolism, and priming you for another binge later in the day. (Think: You've skipped breakfast and lunch, so you're ready to takedown a whole turkey by dinner!) Make it your mission to eat three meals and two snacks every day, and don't wait longer than three to four hours without eating. Set a "snack alarm" on your phone if needed.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
