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.
Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
Create a seven-day meal plan. This meal plan should include three main meals (breakfast, lunch, dinner), scheduled at the same time of day, as well as two small snacks (between breakfast and lunch, and lunch and dinner), also schedule at the same time of day. This will ensure you eat at a consistent time for all seven days and do not skip or miss a meal. Eating about 1,400 calories a day, combined with daily exercise, can lead to healthy weight loss.[4]
Make instant oatmeal and add in dried fruit and nuts for a healthy, fiber packed breakfast. Add 1 ⅓ cup fat-free milk to two packets of instant oatmeal (look for no sugar added oatmeal). Cook it according to the package directions in the microwave or the stove. Once it's cooked, mix in two tablespoons dried cranberries and one tablespoon chopped walnuts.
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.

Integrate fish into your diet with a tilapia and rice pilaf dish. Heat up one teaspoon olive oil in a pan over medium-high heat. Season a three-ounce tilapia fillet with some salt and pepper. Place it in the pan for about two to three minutes per side. When the fish is done, it should flake easily with a fork. Prepare ½ cup rice pilaf (prepared from a box or made from scratch) and ½ cup steamed snap peas. Serve the tilapia with the rice pilaf and the snap peas. Finish the meal with a baked apple, topped with a pinch of cinnamon and one teaspoon honey, served with ⅓ cup low-fat vanilla ice cream.
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.
Your sleeping patterns have a lot to do with your weight. Lack of adequate sleep can eventually lead to weight gain. Here’s how – you feel tired since you didn’t sleep properly the previous night. As a result, you might be tempted to skip exercise the next day or any other regular activity that involves physical movement. And to make things worse, you are tired at your workplace, and tend to grab a pack of chips or a donut to get an instant burst of energy. And there you go – you have just created the recipe for disaster. A study published in the American Journal of Clinical Nutrition found that those individuals who got inadequate sleep were prone to late-night snacking. They were also more likely to choose high-carb snacks (3). Another study had revealed that sleeping too little can prompt someone to have bigger portions of foods.
With just seven days, you also don't have time to put together a total weight loss workout program. And if you try to do hardcore fat-burning workouts without any previous experience, you could easily injure yourself. So if you want to lose weight in a week, increase your steps per day to burn more calories. Exercise can also help reduce stress and improve your sleep, both of which may also contribute to weight loss.
It’s time to focus on your lentil health. In one four-week Spanish study, researchers found that eating a calorie-restricted diet that includes four weekly servings of legumes aids weight loss more effectively than an equivalent diet that doesn’t include beans. Those who consumed the legume-rich diet also saw improvements in their “bad” LDL cholesterol levels and systolic blood-pressure. To reap the benefits at home, work lentils, chickpeas, peas and beans into your diet throughout the week.
