Day 2 and I want to quit already

It will get better. The extreme hunger only last for the first few days (about 3 for me). Soon you will get into the swing of logging all your food and feeling better with the decrease in calories. Just try to keep yourself busy and out of the kitchen. Workout, go shopping...anything to keep your mind off the food!!

I have learned, through MANY attempts at this, to take it slow and steady. I eat three meals and 2-3 snacks a day (all within my calorie limit), which means I am eating about every 2 hours to keep myself from ever feeling so hungry I would want to give in. I try to have at least a little protein with each meal/snack, which helps with the hunger issue too.

I also try to exercise 6 days a week. I have built up from 15 minutes a day to 40. The exercise helps me in many ways; one of my favorites is that I get to eat a little more!!!

What is your calorie goal set at? If you are constantly hungry, it may be set too low for right now.

Let me guess....1200 calories?

What is your calorie goal set at? When I was feeling like that I bumped mine up 100 calories and it made all the difference. Also, if you exercise you get extra calories.

I seen a meme today on Pinterest under motivation. It said : Some quit due to slow progress. Never grasping the fact that slow progress..... is progress. Hang in there

How tall are you and your weight+age? What amount of cals are you trying to eat and how much exercise are you getting?
You may be at too high of a deficit. You can reset your goal to lose at say, .5 to a pound a week, which will be slow, but you'll have more calories available.
If the deficit is not the problem, then try to up your protein and fiber to feel full. It would be helpful if we look at your food diary.
Also, if you've gotten used to eating quite a bit, then eating much less WILL be an adjustment. I've found that at first, I couldn't imagine eating so "little" but now, I'm wondering how I ate SO MUCH. its all about your perspective. Things that I would have easily eaten before now really make me uncomfortably full while eating less than what I would have eaten.

A couple of things: First you say this is day 2 but your ticker says you have lost 2 lbs. If you lost 2 lbs yesterday - that could be the reason you are starving. Make sure you are eating at/or above the calorie level recommended by MFP to lose 2 lbs. a week. If you have less than 25 to lose - move it to 1 lb. per week.

Next - there is no quitting - this isn't a diet. This is a healthy eating/healthy living plan. What you do today and this week needs to be/lead to a sustainable lifestyle. I know it sounds strange - but under eating now won't help the weight come off and stay off in the long run...because you will be back starting over again in a few weeks or few months.

Next - make sure your "starving" is physical and not mental. Best gauge for me - when my stomach growls, I'm hungry. If it's not growling it's not time to eat. Learn to listen to your body and not your mental mind set of it's lunch time, dinner time, I ate less for lunch so I'm starving, etc.

Open your diary if you want specific help - it really will lead to better suggestions.

When you reduce carbs, you need to increase fat intake to give energy.

Then up your calories! Your TDEE at a sedentary activity level is around 2040. Subtract 20% off of that for weight loss and you could be eating around 1600 per day and still lose weight.

Edited for typo.

Have patience. This is a marathon, not a race.

Don't set such an aggressive weight loss goal, or yes, you will want to quit! Drastic changes almost always send people off the rails.

The right way to do this is not to punish yourself, and not to go hungry. Just be accountable and stick with it.

Try for the half-pound a week loss goal. If you accurately weigh, measure, and log everything, and manage stay within that higher number of calories for a while, you'll establish good habits. Then, start cutting back your calories a little and moving a little more, and see what happens.

protein helps keep you feeling full longer. try including more protein in your breakfast; bacon, eggs, greek yogurt, spinach omelet. i've learned over the years through trial and error that consuming more protein is key. while carbs provide you energy, protein gives you a full feeling much longer so you don't feel like you're starving yourself til the next meal.

try keeping protein snacks nearby: hardboiled eggs, 2% greek yogurt, tuna w/avocado. and have a snack to tide you over til your next meal. something that has worked for me is eating 6 small meals/snacks a day every 2-3 hours. i rarely feel hungry and most of my meals are high in protein... if a carb is included i make sure it's a complex carb and/or high in fiber.

if you really want something, you'll find a way to achieve it!! you can do it! g'luck!

also...

even though you've done MFP before, you haven't made sustainable changes... or you wouldn't be back here again.

while you aren't "new" to this, these might help.

1. don't trust the initial setup that MFP provides. If you put in the wrong/inaccurate information, it'll tell you to eat an amount that may not be applicable.
2. Make sure you eat enough.
3. Figure out what works for you and is sustainable/healthy/long term.
4. avoid fads. don't buy in to any "Hey, try the twinkie and vodka diet"
5. Don't cut out anything now that you don't plan on literally giving up forever.
6. GET A FOOD SCALE. Weigh everything. No, seriously.
7. Get an HRM with a chest strap. You'll at least have a better idea of what you're burning. It'll be more accurate than the generic info in the exercise database.. and even more than the cardio machines. This is great for steady state cardio (run/walk/etc)
8. Don't go balls out. You'll burn out. I see 300 lb people show up here, instantly start working out and cutting their intake SEVERELY... trying to cut out all of their carbs at once.. whatever. Take it slow. Figure out how much you need to eat FIRST in order to lose.. then incorporate exercise.
9. Don't cardio yourself to death.
10. Take the information on the forums with a grain of salt. A lot of people that have been here for a while.. and have been successful, may seem jaded. They give out GREAT advice day after day, only to be met with people that refuse to listen.
11. Eat real food. Not diet food. Not "low fat, sugar free, now without X." It's easier to get/find/count.
12. don't set time restrictions.
13. measure yourself weekly. Don't just weigh. Measure and take pictures.
14 BE PATIENT.
15. Avoid forum topics that have "1200" in the title. It's just full of butthurt. Lots of it.
16. If you ask a question on the forum, give as much information as you can ("yes, I have a food scale and weigh my food" is worlds better than "I eat a palm full of miscellaneous boiled chicken parts..sometimes.")
17. Be honest with yourself and honest with us.
18. This isn't a game, it's about changing your lifestyle. Do that.

pretty much that.

...and don't fall into the "1200 calorie" vertigo of suck because of:

the typical MFP users does this:
1. I wanna lose weight, let's try MFP.
2. OH! Wow, it tells me I can lose 2 lbs a WEEK? AWESOME!
3. I just sit at a desk when I'm not working out, I guess I'm sedentary.
4. MFP tells them 1200 calories, and they don't even eat that.. then they work out on top of it.. creating an even bigger deficit.
5. Lose a lot, fast, brag about 1200 calorie success.
6. Come back in a few months trying to figure out why they're dizzy, tired, not losing weight.
7. Get on the forums, ask why they aren't losing.
8. Get two responses (I eat 1200 and lose) (I eat 2200 and lose)
9. Argument ensues about who is right.

Now. That being said. These threads happen hundreds of times per day. Most times, and I mean really.. seriously.. 95% of the time.. people get the 1200 number because they don't put the right information in when they set up the account. There are a great number of people that are trying to help. I'm one of 'em.

I'm a hardcore advocate of actually finding out what works for the individual.. by means of other calculators, averages, time, practice, and patience.

Blanket prescriptions of 1200 calories "because it worked for me" is more harmful to the generic new user than the "figure out what you need to eat." Unfortunately, one is a LOT easier to type.

...and here's another approach.

Block off 6 weeks. log EXACTLY what you eat for those six weeks, weigh at the beginning, weight at the end. If you've lost, you're eating under your TDEE. If you haven't lost, congrats.. you found your TDEE, if you've gained... then you're above TDEE.

From there, look at how much you lost or gained and you have a rough estimate of how to shift your intake to balance it out.

Online calculators are great, but they're just estimates. They give you decent ideas for starting points. From there, it's on you to fine tune it.

Never be hungry! There are many low cal foods that are filling and you should incorporate these. For example, If you do cereal in the morning try a big bowl of puffed brown rice with berries or grapes and low cal skim milk. You can eat lots of low cal soups and fresh veggies and fruits in addition to whatever else you are eating. I have a good appetite myself and have found these foods not only make me fee good but I'm also never hungry.
