Sticking to a conventional diet and exercise plan can be difficult.
However, there are several proven tips that can help you eat fewer calories with ease.
These are effective ways to reduce your weight, as well as to prevent weight gain in the future.
Here are 11 ways to lose weight without diet or exercise. All of them are based on science.
Your brain needs time to process that you've had enough to eat.
How quickly you finish your meals may also affect your weight.
A recent review of 23 observational studies reported that faster eaters are more likely to gain weight than slower eaters (
Fast eaters are also much more likely to be obese.
To get into the habit of eating more slowly, it may help to count how many times you chew each bite.
Summary Eating your food slowly can help you feel more full with fewer calories. It is an easy way to lose weight and prevent weight gain.
The typical food plate is larger today than it was a few decades ago.
This trend could contribute to weight gain, since using a smaller plate may help you eat less by making portions look larger.
You can use this to your advantage by serving healthy food on bigger plates and less healthy food on smaller plates.
Summary Smaller plates can trick your brain into thinking you're eating more than you actually are. Therefore, it's smart to consume unhealthy foods from smaller plates, causing you to eat less.
One study found that increasing protein intake from 15% to 30% of calories helped participants eat 441 fewer calories per day and lose 11 pounds over 12 weeks, on average, without intentionally restricting any foods (
If you currently eat a grain-based breakfast, you may want to consider switching to a protein-rich meal, such as eggs.
In one study, overweight or obese women who had eggs for breakfast ate fewer calories at lunch compared to those who ate a grain-based breakfast (
What's more, they ended up eating fewer calories for the rest of the day and during the next 36 hours.
Some examples of protein-rich foods include chicken breasts, fish, Greek yogurt, lentils, quinoa and almonds.
Summary Adding protein to your diet has been linked to weight loss, even without exercise or conscious calorie restriction.
This is also linked to weight gain (
One recent study found that if high-calorie foods are more visible in the house, residents are more likely to weigh more than people who keep only a bowl of fruit visible (
Store unhealthy foods out of sight, such as in closets or cupboards, so that they are less likely to catch your eye when you're hungry.
On the other hand, keep healthy foods visible on your countertops and place them front and center in your fridge.
Summary If you keep unhealthy foods on your counter, you are more likely to have an unplanned snack. This is linked to increased weight and obesity. It’s better to keep healthy foods — like fruits and vegetables — in plain sight.
Eating fiber-rich foods may increase satiety, helping you feel fuller for longer.
Viscous fiber forms a gel when it comes in contact with water. This gel increases nutrient absorption time and slows down the emptying of your stomach (
Viscous fiber is only found in plant foods. Examples include beans, oat cereals, Brussels sprouts, asparagus, oranges and flax seeds.
A weight loss supplement called glucomannan is also very high in viscous fiber.
Summary Viscous fiber is particularly helpful in reducing appetite and food intake. This fiber forms gel that slows down digestion.
Drinking water can help you eat less and lose weight, especially if you drink it before a meal.
One study in adults found that drinking half a liter (17 ounces) of water about 30 minutes before meals reduced hunger and lessened calorie intake (
Participants who drank water before a meal lost 44% more weight over a 12-week period compared to those who did not.
If you replace calorie-loaded drinks — such as soda or juice — with water, you may experience an even greater effect (
Summary Drinking water before meals may help you eat fewer calories. Replacing a sugary drink with water is particularly beneficial.
Portion sizes have increased during the last few decades, especially at restaurants.
One study in adults found that doubling the size of a dinner appetizer increased calorie intake by 30% (
Serving yourself just a little less might help you eat significantly fewer calories. And you probably won't even notice the difference.
Summary Larger portion sizes have been linked to obesity and may encourage both children and adults to eat more food.
Paying attention to what you eat may help you consume fewer calories.
People who eat while they're watching TV or playing computer games may lose track of how much they have eaten. This, in turn, can cause overeating.
One review of 24 studies found that people who were distracted at a meal ate about 10% more in that sitting (
Additionally, absent-mindedness during a meal has an even greater influence on your intake later in the day. People who were distracted at a meal ate 25% more calories at later meals than those who were present (
If you regularly consume meals while watching TV or using electronic devices, you could be inadvertently eating more. These extra calories add up and have a massive impact on your weight in the long term.
Summary People who eat while distracted are more likely to overeat. Paying attention to your meals may help you eat less and lose weight.
When it comes to health, people often neglect sleep and stress. Both, in fact, have powerful effects on your appetite and weight.
Summary Poor sleep and excess stress may imbalance several important appetite-regulating hormones, causing you to eat more.
Added sugar may very well be the single worst ingredient in the diet today.
Staying away from these beverages entirely can provide enormous long-term health benefits. However, note that you should not replace soda with fruit juice, as it can be just as high in sugar (
Summary Sugary drinks have been linked to an increased risk of weight gain and many diseases. Your brain doesn't register liquid calories as it does solid foods, making you eat more.
One unusual strategy is to use red plates to help you eat less. Research indicates that this technique at least seems to work with unhealthy snack foods.
One study reported that volunteers ate fewer pretzels from red plates than from white or blue plates (
The explanation may be that we associate the color red with stop signals and other man-made warnings.
Summary Red plates may help you eat fewer unhealthy snack foods. This may be because the color red triggers a stop reaction.
Many simple lifestyle habits can help you lose weight. Some have nothing to do with conventional diet or exercise plans.
You can use smaller plates, eat more slowly, drink water and avoid eating in front of the TV or computer. Prioritizing foods rich in protein and viscous fiber may also help.
However, it’s probably best not to try all these things at once. Experiment with one technique for a while, and if that works well for you then try another one.
A few simple changes can have a massive impact on your weight over the long term.
