I Eat A Lot But I Am Still Not Gaining Weight. Why Is That?

There can be many reasons of not gaining weight despite of eating too much. One reason can be worms in the digestive tract. Another reason can be high metabolism rate in you body. I advise you to visit a doctor for proper diagnosis and treatment.

Many answers for this one.  Have you recently began abstaining from alcohol? Alcohol consumption accounts for a lot of empty calories, which add weight with no benefits.  If you have decreased alcohol consumption for a better diet, this is normal.  Healthy calories from food is much better than empty sugar calories provided by alcohol.  Also, consider body size & bone structure when trying to determine appropriate weight  if you have been doing muscle building exercises, remember that muscle weighs more than fat, so  that should be taken into consideration. 

Its probably high metabolism. I have it too. I'm 15. 5,8 ft tall. Really skinny, but I eat and I do feel like there is food in my stomach. However when I look in the mirror, I see skinny... Which I am. But my mother was the same so GENES.

Tips! Eat every 2 hours. Drink juices, soft drinks or milk like all the time, especially when your at home. Carry nuts in your bag so you always have some protein to snack on wherever you go. Avoid sugary foods cus they get used up faster in your stomach. EXERCISE. Guys: Go to the gym at least 4 times a week. Girls: The same, otherwise jogging everyday early morning works. This is important so you don't develop little fatty areas around your body, like an old person....dripping...of fat....eugh....

Good luck!

We see that problem all the time so I can't truly say it is a problem. As long as your body is telling you that it is getting enough nutrients, don't worry.  It may be in genes.  You are probably a  active person at this time. I am willing to say when you get older and you body, life, exercise slows down, you will be asking the opposite question.  Enjoy!

Because you're not eating over your maintenance.

Your body requires a certain amount of calories to maintain it's current
weight (body weight in lbs x 15)...so if you were 150 pounds, that would be
150x15 = 2,250 calories/day.

If you ate around 2,250 calories each day, you would not put on weight...

It is also possible you are eating a bit more than your maintenance but because you are physically active (running/or engaging in some other sport) you are burning those extra calories (1 hour of strenuous activity = about 500 calories burned).

Also, keep in mind, not all foods are created equal.

You could eat a pound of broccoli and only add 154 calories to your
daily caloric intake, or you could eat a pound of pizza and add 1,200
calories to your daily intake.

You could be eating a lot of low calorie foods throughout the day.

Also, one last thing is that your idea of 'a lot' may not be in line with other people's ideas of what a lot of food is...and you may in fact not be eating much food at all.

Regardless, if you started counting every single calorie that went into your mouth, got a food scale and weighed out ALL your food...and also track your calories burned through exercise and even walking...you'd quickly determine what is going on.

I'm having the same problem but I know I have a really high metabolism, I'm really healthy and I have been eating fast food a lot, I have gained some pounds like I was 110 now I'm around 129, I also work out and em very active.

I have the exact same problem. I'm 89 and 16 Years old. I have no boobs and a little butt but I'm pretty. But I still feel insecure
