Help! Why am I not loosing?

What do you eat in a day? It would be helpful to see your diary.

Are you measuring your foods? Weighing them when needed? Or do you "eyeball" your servings?

Do you pay attention to the portion sizes on things? For example, the small cartons (500mls) of milk/chocolate milk most people drink in a sitting but that carton is actually two servings.

Do you drink enough water? Do you eat a lot of processed and packaged foods? As quick and easy as frozen lunches/dinners are they are LOADED with sodium.

Do you eat back your exercise calories? What is your weight loss goal set at?

1,200 may be too little for you. This site puts a lot of people at that goal and for most people it's far too little. It's weird but you can lose weight (and sometimes lose it faster) eating more.

Females don't really bulk up with lifting weights unless they are taking some form of suppliment. Do you think you are bulking up because your muscles look bigger afterwards? Could be water retention/muscle repair. Do you think you are bulking up because of gains on the scale? Again could be water/muscle repair however could be increasing muscle mass (which can be hard to do at such low calories though).

First of all it's important you don't get discouraged. Now, this could be happening for different reasons:

1. Too much sodium: If you are eating too much canned food (including tuna), too much salt, or not drinking enough water, you might be retaining liquid in your system.

2. Not tolerant to Carbs: You might not be so tolerant to big amounts of carbs. Have you noticed you tend to gain weight easily while having an average amount of carbs? The next day after eating carbs you tend to feel heavier, or bloated? Have you suffered from hyperinsulinism in the past? If any of these is your case, you might need to go to your goals and reset them. Instead of using the "custom" ones by MFP, you should create your own, where you eat at least 40% of protein, 30-40% carbs 20-30% fat.

3. Too many cheat meals: We tend to believe cheat days or cheat meals are necessary for us, when actually what would be ideal is to add some calories once or twice a week, while still making good choices. So if you've been having one cheat day a week, you might be gaining some of the small amount of weight you've been losing. Instead try to add around 200 calories once or twice a week in high protein, high fiber food, such as veggies, fruits, lean meats, and nuts

I hope this helps you.

I suggest you eat more fresh vegetables and less refined sugar. Those two changes should help a lot. Also, you might try increasing your calories. 1200 is too little for most people.

LOSING

eat more or at least eat the 1200+ half your exercise calories back

start taking your measurements and keep track of that

exercise isnt necessarily going to help with weight loss but it will definitely help with how you lose the weight. i lift heavy and am not bulking up because bulking up is more a factor of how many calories you are eating than how much weight you are lifting. if you're eating at a deficit then lifting heavy will make sure that you safe guard as much of your muscle mass as possible while losing weight. when you lose weight, your body will burn muscle as well as fat and glycogen, but if you lift heavy you tell your body to preserve the muscle since you're using it. you want to preserve muscle because that keeps your metabolism high since muscle is more active tissue than fat

I looked at the last few days of your food diary. You're not eating real food. Too many carbs/sugar and not enough protein or fat. Not to mention too many processed foods. I realize not everyone likes to cook or has time but here's a sample diet that is easy to make and far more nutritional.

Breakfast: two eggs, berries with almond slivers
Lunch: salad with olive oil/basamico and meat (chicken, tuna or similar)
Dinner: meat, salad, green veggies

Skip the jello, corn products, etc.
