There are also studies showing that keeping a food diary and writing down what you eat, or taking pictures of all your meals, can help you lose weight (28, 29).
Keeping healthy food close by can help prevent you from eating something unhealthy if you become excessively hungry.
A few snacks that are easily portable and simple to prepare include whole fruits, a handful of nuts, baby carrots, yogurt and a hardboiled egg (or two).
Although I'm not aware of any studies on this, many people recommend brushing your teeth and/or flossing right after dinner. Then you won't be as tempted to have a late-night snack.
Spicy foods like Cayenne pepper contain Capsaicin, a compound that can boost metabolism and reduce your appetite slightly (30, 31).
15. Do Aerobic Exercise
Doing aerobic exercise (cardio) is an excellent way to burn calories and improve your physical and mental health.
It appears to be particularly effective to lose belly fat, the unhealthy fat that tends to build up around your organs and cause metabolic disease (32, 33).
16. Lift Weights
One of the worst side effects of dieting, is that it tends to cause muscle loss and metabolic slowdown, often referred to as starvation mode (34, 35).
The best way to prevent this from happening is to do some sort of resistance exercise, like lifting weights. Studies show that weight lifting can help keep your metabolism high, and prevent you from losing precious muscle mass (36, 37).
Of course, it's not just important to lose fat. You also want to make sure that what is beneath looks good. Doing some sort of resistance exercise is critical for that.
17. Eat More Fiber
Fiber is often recommended for the purpose of weight loss. Although the evidence is mixed, some studies show that fiber (especially viscous fiber) can increase satiety and help you control your weight over the long term (38, 39).
18. Eat More Vegetables and Fruits
Vegetables and fruits have several properties that make them effective for weight loss.
They contain few calories, but a lot of fiber. They are also rich in water, which gives them a low energy density. They also take a while to chew, and are very filling.
Studies show that people who eat vegetables and fruits tend to weigh less (40). These foods are also super healthy and nutritious, so eating them is important for all sorts of reasons.
19. Chew More Slowly
It can take a while for the brain to "register" that you've had enough to eat. Some studies show that chewing more slowly can help you eat fewer calories and increase the production of hormones linked to weight loss (41, 42).
20. Get Good Sleep
Sleep is highly underrated, but it may be just as important as eating healthy and exercising.
Studies show that poor sleep is one of the strongest risk factors for obesity, being linked to an 89% increased risk of obesity in children, and 55% in adults (43).
21. Beat Your Food Addiction
A recent 2014 study of 196,211 individuals found that 19.9% of people fulfil the criteria for food addiction (44).
If you suffer from overpowering cravings and can't seem to get your eating under control no matter how hard you try, then you may be a food addict.
In this case, get help. Trying to lose weight without dealing with this problem first is next to impossible.
22. Eat More Protein
Protein is the single most important nutrient when it comes to losing weight.
Eating a high protein diet has been shown to boost metabolism by 80 to 100 calories per day, while helping you feel so satiated that you eat up to 441 fewer calories per day (45, 46, 47).
One study also showed that protein at 25% of calories reduced obsessive thoughts about food by 60%, while cutting the desire for late night snacking in half (48).
This is the single most important tip in the article.
Simply adding protein to your diet (without restricting anything) is one of the easiest, most effective and most delicious ways to lose weight.
23. Supplement With Whey Protein
If you struggle to get enough protein in your diet, taking a supplement can help.
One study showed that replacing part of your calories with whey protein can cause weight loss of about 8 pounds, while increasing lean muscle mass (49).
24. Don't Drink Calories, Including Sugary Soda and Fruit Juices
Sugar is bad, but sugar in liquid form is even worse (50). Studies show that liquid sugar calories may be the single most fattening aspect of the modern diet.
For example, one study showed that sugar-sweetened beverages are linked to a 60% increased risk of obesity in children, for each daily serving (51).
Keep in mind that this applies to fruit juice as well, which contains a similar amount of sugar as a soft drink like coke (52).
Eat whole fruit, but use fruit juice with caution (or avoid it altogether).
25. Eat Whole, Single Ingredient Foods (Real Food)
If you want to be a leaner, healthier person, then one of the best things you can do for yourself is to eat whole, single ingredient foods.
These foods are naturally filling, and it's very difficult to gain weight if the majority of your diet is based around them.
Keep in mind that real food doesn't need a long list of ingredients, because real food IS the ingredient.
Here is a list of the 20 most weight loss-friendly foods on earth.
26. Don't "Diet," Eat Healthy Instead
One of the biggest problems with "diets," is that they almost never work in the long term.
If anything, people who "diet" tend to gain more weight over time, and studies show that dieting is a consistent predictor of future weight gain (53).
Instead of going on a diet, make it your goal to become a healthier, happier and fitter person. Focus on nourishing your body, instead of depriving it.
Weight loss should follow as a natural side effect.
