Always hungry, gaining weight.

Working out will cause you to gain water weight. Too much sodium will cause you to gain water weight - if you aren't drinking enough water to flush it out, that is. So, drink water and that should help a fair bit.

What you eat is pretty important - protein and fat will keep you satiated longer, so I'd definitely suggest eating more of that! It can make a huge difference in how you feel. Also, you might want to try spacing your food out differently; it looks like you only really eat two meals... maybe try breaking it all up into several mini meals so you aren't starving? I tend to do that - three smallish meals and lots of snacks.

How long have you been doing this? Just for the 5 months or has it been longer? If it's been longer and this is a recent development (the ravenous hunger, that is), I'd suggest going to the doctor.

If you're actually eating 1750 and not just BSing us you are losing weight, regardless of what your scale is reading. Losing weight takes a long time, don't expect results right away.

I recently went from a very low cal diet with lots of cardio to strength training, swimming and eating more of a body builders diet still keeping track and having a deficit but not as strict.
I cannot view your diary but we are about the same size i.e. height and weight. I have switched from 2% to almond milk (unsweetened vanilla) in my cereal which I only eat whole healthy cereals like oats. Smart slower digesting carbs like brown rice will help you feel full longer and satisfy that hunger you are having. I will eat a 2 cup bowl of cereal when I am really hungry with a cup of berries and still be well under 300 calories. I had to start eating smart and filling vs binging. I also eat every three hours and drink a very large glass of water before my meal and with my meal. There are sooooo many times that people think they are hungry when in fact they are mostly thirsty.
I also changed up my cardio intensity to set the pitch on it to the highest setting after my five minute warm up. I found that the higher pitch gave me that rapid huff and puff without the running I so hate without making me feel like I was going to fly off the thing or pass out. LOL.
Changing up my workouts and diet helped me lose 45 lbs so far (about 120 days) and I am insulin resistant (PCOS)

Veggies... They will help prevent you from being as hungry without raising your calories by much.

Yes, what they said^^^. More specifically, when I looked through a few days of your diary, what was glaringly missing was FIBER. Fiber is very filling and very good for you. You should be getting at least 25g/day, for optimum health. Here's a sloppily formatted (sorry, I don't know how to keep formatting in here) chart of fruits & veggies, along with their fiber content:

Raspberries 1 cup 8.0
Pear, with skin 1 medium 5.5
Apple, with skin 1 medium 4.4
Banana 1 medium 3.1
Orange 1 medium 3.1
Strawberries (halves) 1 cup 3.0
Figs, dried 2 medium 1.6
Raisins 1 ounce (60 raisins) 1.0

Legumes, nuts and seeds Serving size Total fiber (grams)*
Split peas, cooked 1 cup 16.3
Lentils, cooked 1 cup 15.6
Black beans, cooked 1 cup 15.0
Lima beans, cooked 1 cup 13.2
Baked beans, vegetarian, canned, cooked 1 cup 10.4
Sunflower seed kernels 1/4 cup 3.9
Almonds 1 ounce (23 nuts) 3.5
Pistachio nuts 1 ounce (49 nuts) 2.9
Pecans 1 ounce (19 halves) 2.7
Vegetables Serving size Total fiber (grams)*
Artichoke, cooked 1 medium 10.3
Green peas, cooked 1 cup 8.8
Broccoli, boiled 1 cup 5.1
Turnip greens, boiled 1 cup 5.0
Brussels sprouts, cooked 1 cup 4.1
Sweet corn, cooked 1 cup 4.0
Potato, with skin, baked 1 small 3.0

Best of Luck!

Two things that really helped me to control my hunger:

In the beginning of 2012 it was spacing out my eating to about every 3 hours. This was a completely foreign concept to me, as I was an eater that had either 2 big meals a day, or a bunch of snacks & 1 big meal.
I would set an alarm on my phone to go off at certain times & the label I would put the calories I'd expect to consume (200-250 if it was a snack, 350 for lunch, etc.) It helped a huge amount & eventually became a regular habit that I still do (though I don't need an alarm anymore.)

The other thing was upping my protein beginning of last year. I went from about 15-20% (I was eating mostly vegan) & upped it to 25%. HUGE difference. After a few weeks I tried upping it to 30% but I felt weird so I kept it at 25%, pretty much all last year. The past few months however, I eat 30% (and sometimes 35%) and have been doing well with that too.

Also, if you eat healthy, you can eat SO MUCH MORE FOOD for little calories that fill you up. I usually eat around 1500-1600 (I'm 5'2") but on days where I end up eating only 1200, I wasn't hungry because I ate so fabulously I didn't really need to eat more to fulfill my hunger.

I have the same problem and always feel hungry.

I noticed when I do activities that I love and focus my time of doing good things the feeling of hunger goes away. I have to fight this huger battle for a long time. As humans we need this hungry feeling in order to push us to do great things with out lives.

Try not to consume/stress yourself on the foods your eating while making conscious choices on healthy food. like myself, start a habit of finding out when your are hungry and if there is a place where its a trigger try to avoid that situation.

I hope that helps.

In my opinion, salt is the issue. Your body works constantly to keep the amount of salt and the amount of water equal. If you're ingesting lots of salt, your body will hold onto extra water for that purpose. Also long term excessive salt is pretty bad for your health in general.

I'd also try to work more fresh food in there - veggies and fruit.

Can you find a lower carb alternative to your tortillas?

And one last thing - it looks like you're drinking about 500 calories on average a day. That's kind of a lot, again - IMO.

All of the above is just based on things I've read and personal experience.

Good luck!

The majority of your calories are from sauces/seasonings and from a beverage. All the carbs that you are eating are simple carbs i.e. white bleached and enriched which is not healthy and quickly digested as a sugar. Simple things like NOT drinking your carbs, using seasoning packets that are low or no cal like lemon pepper or I have a really great one that is bacon mesquite. More 0 cal beverage choices like citrus green tea and water would help flush out the sodium you are retaining from the processed things you are eating. I got rid of EVERTHING WHITE in my house, day one. wrote a grocery list and had a cook day.

Find a way to eat breakfast. Eating breakfast (properly) will keep you fuller longer and allow your body to fuel up for the day. You need to eat more.

This is not true for everyone. For many people breakfast does not keep them fuller for longer. Personally once I start eating I'm hungrier as I go. Your body certainly does not require it to fuel the day. Stored fat can fuel the day. Many people find eating 1 or 2 large meals in a day to be the most satiating way to organize meals. People who do 16 hour intermittent fasting mainly do so because it helps keep them full. Most of them skip breakfast. If satiation is a problem, intermittent fasting is one avenue to consider along with altering the diet to include more satiating choices as all the others have pointed out. Don't waste calories on liquids, or sauces either. They do next to nothing for satiation.

Okay. But we don't know that the reason he doesn't eat breakfast isn't just laziness (sorry OP), as against oh I ate breakfast but it just made me hungrier. Basically if someone's hungry, my first advice is to try eating. I don't believe in white knuckling it unless you have to

In the non-food area, how's your sleep?

When you don't get enough sleep, your body produces too much of a hormone that makes you feel hungry and too little of another hormone that makes you feel full.

I have always noticed that starving to death all day is a sign that I haven't gotten enough sleep (assuming I have, actually, eaten enough, of course.)

In the last week, your diary show you are way over sodium levels. It could be water retention. Give it a week or two and see what happened, because then you will now if it's water or actual weight gain.

Also, though it has nothing to do with weight gain if you are eating at a deficit, your nutrition looks pretty bad. If you clean it up and add more protein and more nutrient dense calories you will feel more satiated.
