Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed monounsaturated-rich oils (like high-oleic canola oil or avocado oil) with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of the monounsaturated-rich oil daily lost nearly two percent of their belly fat in just one month.

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.

Avocados are rich in monounsaturated fatty acids, dietary fiber, potassium and phytochemicals. People who eat avocados tend to have lower BMI, body weight and waist circumference than people who skip this green superfood, per a study in Nutrition Journal. While avocados are higher in calories than other fruits and vegetables, their satisfying fat and fiber combo may help you slim down. Add some to your salad, sandwich or taco night for a burst of creaminess and flavor.

It's a one-time investment you'll never regret. Here's why: Strength training builds lean muscle tissue, which burns more calories — at work or at rest — 24 hours a day, seven days a week. The more lean muscle you have, the faster you'll slim down. How do you start strength training? Try some push-ups or a few squats or lunges. Use your free weights to perform simple bicep curls or tricep pulls right in your home or office. Do these exercises three to four times per week, and you'll soon see a rapid improvement.
Sure, you certainly need to drink plenty of water to help combat bloating, you can (and should!) also consume high-water content foods. Reach for cucumbers, tomatoes, watermelon, asparagus, grapes, celery, artichokes, pineapple, and cranberries — all of which contain diuretic properties that will also help you stay full due to their higher fiber content.
This might come as something unexpected for most of you, but hey, soups have their own advantages. Having a soup at the beginning of a meal can curb your appetite, and you will only end up eating less. Also, soups can be highly nutritious but low in calories – precisely something every person who wants to lose weight needs. In a study conducted at The Pennsylvania State University, it was found that consuming low-energy-dense soup can help decrease your calorie intake and enhance weight loss (6). You can ideally go for vegetable-based soups, soups made of chicken or beef broth, and tomato soups without the cream – these will fill you up with fewer calories (7).
Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.

As long as this popular crunchy treat isn't doused in movie-theater butter, it makes an excellent weight-loss snack. Not only is popcorn high in fiber, it even delivers some protein. A 1-ounce serving of air-popped corn (about 3½ cups) has 4 grams of fiber, almost 4 grams of protein and clocks in at 110 calories. This combination makes it a snack with staying power. Popcorn is filled with air, so you get a pretty large portion without a lot of calories. You can eat 3 whole cups of popcorn for only 100 calories.

Decision fatigue is real, and it could be hindering your ability to shed some pounds. A study published in Social Science and Medicine  found those who have high levels of what’s called “skill discretion”—i.e., they exercise control by getting things done themselves—tended to have lower BMIs. In contrast, those who are constantly deciding on courses of action for others may eventually come down with decision fatigue and make ill-informed choices, such as ordering that piece of cheesecake for dessert.
There’s some truth to the old adage that breakfast is the “most important meal of the day,” and if you’re looking to blast belly fat, what you eat at the start of each day can make all the difference. According to a study from the University of Missouri-Columbia, a high-fiber, high-protein breakfast may be the most important investment you can make for your waistline. The study showed that eating breakfast triggered women’s brains to release dopamine, a feel-good chemical that helps to control impulses. In other words, eating a balanced breakfast decreases your chances of reaching for that 3 p.m. candy bar and keeps your belly slim.

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.
