<p>You must be making a mistake in calorie intake.</p>
<p>If the calories entering your body are more than the calories you burn, you gain weight. That's the main logic. You must be patient in this process.</p>
<p>One of my friends was complaining about this problem. When I asked him, he said didn't count calories. He said I was eating too much like you . I told him to count calories for a week. The calories it took during the week was about 2000. But he need to 2500 for gain weight.</p>
<p>You can easily calculate the calories calculators in internet . I recommend you to fatsecret about it. You can calculate the needed calorie for gain weight within the application. You can also track the calories , macros and micros . If you are unable to gain weight even in the calories you are targeting, increase your calorie goal to 300-500.</p>
<p>You may need to consume more calories to gain weight. In this case, you can eat small volume and high calorie foods. Olive oil and nuts are the highest calorie foods.</p>
<p>Make sure you can do sports while trying to get weight. If you do not do sports, the weight you receive is stored as fat. If you do sports, you also gain muscle mass.</p>

<p>It could be good thing or bad thing according to reasons. If total energy taken in day is less than total energy given, it is just normal not to gain weight.</p>
<p>Otherwise, there could be some problems in your stomach. There could be enterozoa in your stomach, could be problem in your digestive system, psychological problems about eating, or hormonal metabolism problems. To make sure you should see a doctor about these problems.</p>
<p>There could be no problem about anything. Your age and your lifestyle could affect your weight and keep you stable about getting weight.&nbsp;</p>
<p>If you wish to gain weight, you should believe and ready yourself psychologically. Then with dietitian, you could prepare a schedule and plan about your meals. Also you should not pass a meal and becareful about time.&nbsp;</p>
<p>You could consume meals with spicy in order to increase your appetite. Also you could consume sweets after your meal in order to not decrasing your appetite.&nbsp;</p>
<p>These could be reasons and you could apply some of them in order to gain weight. I hope this helps and if you have any disease, get well soon.&nbsp;</p>
