Am I eating too much?

2400-2500cals a day, on both training and rest days. 5 5, 145, male, 19.

Run four times a week, 3.5 miles each run, around 30minutes each time.

Lift heavy four times a week (before the runs, split is chest/abs, legs/biceps, back/triceps, shoulders/abs) for a little more than a hour each session, doing compound movements and keeping within 70-90 percent of my 1RM, so that im doing 6-8 reps, to failure sometimes.

Two days train, day off, two more, then weekend off. Plus I'm walkin around campus a lot, like 30min. a day on weekdays.

I WAS maintaining at 140ish for a month. Then all of a sudden the scale started to go up about a half lb a day til i was 145. I thought it was water...but it never went away. Anyways, I looked up on numerous calculators to double check...2500cals seemed right on all of them, maybe a lil low. So I kept at it, because I dont want to lose weight, just maintain. Well, I maintained at 145 for a month, and now the same thing happened last week...each day i gained a lil and now im 150. Once again, I gave it a few days to see if it was water...but its still here.

What gives? This is SOOO frustrating. Am I eating too much? 2500cals is on the low side of my maintentence level, and I'm still gaining? Maybe too little and I'm in starvation mode? I don't think I'm growing anymore. Also, dont say its muscle cuz I'm actually lifting less than before, plus you still need a surplus to grow muscle. I'm about to give up and just get fat.

O yea I'm like 12 percent bodyfat, if that helps.

Well...If you are gaining weight then I'd say it's coming from some where...I'd guess that perhaps if you are lifting so much it could be muscle mass...

If it was muscle tho...shouldnt i be getting stronger?

not necesarily.  Muscle mass is not the same thing as muscle strength.  And your previous statement was incorrect. Its easier to build muscle on a surplus, but its not impossible to do it while you are in a deficit.

I would maybe look at the types of food you are eating, and when you are eating them.  Are you eating every 3-4 hours?  Are you getting enough veggies, lean protein, whole grains etc? Are you eating within 30 minutes after you workout? And just as a reminder, if you are drinking something like gatorade, don't forget to count it.  All of these little things are good to remember, as in reality, a calorie isn't just any old calorie.

Last thing, if you continue to gain weight, usually what people-who-maintain-their-weights-but-not-on- calorie-count do is cut back until they lose it again...

Hmm...well i do eat every 3-4hrs, 30min. before and after workouts, and i count EVERYTHING obsessively. Everything I eat is either whole grain, veggie/fruit, or lean protein (200g a day), but post workout i eat somethin sugary and a protain cuz i heard u should to replace glycogen and prevent further muscle loss. Is this okay?

I really think you are undereating. At 19 and male, you are certainly still growing.  If not taller, then internally- bone, brain, muscle, etc.  

A 19 yr old male who doesn't work out will have a high metabolism.  You work out and lift to add more muscle, so yes you need to add more energy/calories.

Also, at 19 you should add some weight because you are still growing.  So an increase on the scale is a reflection of you body maturing into an adult.

(Can you tell I'm a mom?)

Lol sounds like my mom, she hates how I count cals.

How much cals do you think is a good number?

Here is the link for kids and teens:

Calculator and calorie information for Teens

with your activity level you probably need 3-3500 cals to Maintain.

Good luck!

With how you've described what you eat, when you eat, and all your training, I would say that you are doing very well!

you say that you are gaining weight... how do you feel you look?  I train with a lot of guys (I'm on a co-ed university swim team) and some of those guys have seriously gained 15 pounds of muscle throughout our season, which is probably around 6 months long. They are between the ages of 18 and 23 and definitely still look very toned.

I guess my point is that maybe you should get your body fat tested and base your judgements off of that, instead of a weight number.

Its like me... there are people who weigh 20 pounds less than me but have much more fat.... My "ideal" weight is around 140-145, while there are girls at 130 who have a belly.... I'm just saying, weight is relative and not a determination of how you look/feel about yourself all teh time.
