What is your current height ? The closer a person is to a healthy weight for their height. the harder and longer it takes to lose any perceived excess. While a safe weekly weight loss would be 1-2 pounds for someone who is overweight or obese, someone at a fairly normal weight for their height won't lose that much. In fact, their loss will be much smaller. Ask any of our members trying to lose that last 5-10 pounds and they'll tell you it's slow going. Some may only lose a pound a month ! And that doesn't mean their doing something wrong.
Have you ever had your body fat percentage done ? And not with one of those hand held meters or body fat scales. those are notoriously inaccurate. If you go to your local gym, you can ask a trainer to do a 9 point caliper test. They'll take a set of calipers and pinch nine points on your body. Those numbers will be put into equations and your body fat percentage will be chugged out.
You may well be at a very healthy body fat percentage for your weight. If so, that's why you can't lose. Women are supposed to carry a certain amount of fat to be healthy. If that percentage goes too low, we are at risk for a number of medical problems. Women are constantly bombarded with images and messages that they need to lose weight. Well, some do. But some don't. Depending age and athletic ability, women should carry roughly 20-29% body fat.
I took a sneak peak at your food diary. You're nutrition looks really good. Are you doing any strength training ? If you're not doing any strength training, I'm going to encourage you to start. Add lean muscle because muscle burns fat. the more lean muscle a person carries, the more efficient their body will be at burning fat. Also, a good strength training program could help you lose 1-2 clothing sizes without changing your weight.
That's what most women want, isn't it ? They want to fit into smaller clothes ? Well, they don't have to lose weight to do that. All they need to do is increase their lean muscle because muscle takes up less space on the body than fat. So, consider adding some strength training if you're not. If you are strength training, keep doing it.
If you continue to eat right, watch your portions and get some regular exercise that includes some strength training, you will see change with time. Because you aren't the least bit overweight, your loss will take longer than for someone who is obese.
Patience, it's a virtue.
