Hi lingorus

Just adding my two-cents worth

To begin with, I would suggest that you have FatSecret calculate your RDI for calories. Unless you are working out vigorously many, many hours a day, your RDI shouldn't be 2300 calories when you weigh 121 pounds and you're trying to lose weight. I don't know your details, but I calculated the RDI for someone who is 25 years old, 5'6", 121 lbs. and is very active (highest on the scale of activity) and to maintain that weight, the RDI was 2300 calories. To lose, you would need to eat less than that, but not as low as the amount you're eating.
Looking at your Food Diary, even if your RDI was 1400, like mine, you're eating way below that on a lot of days. It isn't healthy to go below 1000 calories a day for anyone on a long-term basis. Besides that, if you're not feeding your body enough, it will hold onto everything you put in it just in order for it to function as properly as possible.
I also notice that you eat flax fairly often. I love things made with flax seed meal, but had to stop eating it because my body just wouldn't "get rid" of it lol. Even drinking 80-100+ ounces of water a day. If you've had any issues with "voiding", the flax (along with not drinking very much water) could be the culprit.
Even without eating the flax, you should drink at least half of your weight in ounces of water daily. Doing that will also help your bloating issue.
If you've decided that eating low-carb is a way of eating that you can live with, then you may need to follow a strict Induction Phase for 2 weeks. Calculate your RDI, and stay as close to it as you can, plus keep your net carb intake as close to 20 grams a day.
It's great that you've omitted salt from your daily routine

I stopped using regular salt several months ago after I learned that just one teaspoon of salt is equal to the maximum daily requirement of sodium (2300 mgs). Pretty much everything has some sodium in it, but adding salt from the shaker to your food will really get that sodium level up there. I do use a salt substitute, but I've found that I don't use it as often as I used regular salt.
I've eaten the low-carb way numerous times over the last 10 years (before now, always for a "quick fix", lost some weight, but didn't stick with it) and personally, I've never experienced any 2 pound gain a week for 2 weeks after the Induction Phase, nor have I heard anyone else say they experienced that. True, everyone is different, but if you're keeping your net carbs around 20 grams a day, watching your sodium level, drinking lots of water, eating more fat than protein, and also not going over your calculated RDI for calories, you should see a loss, not a gain.
Continue logging your food in the Food Diary. It will help you, and others, to figure out where the problem lies

Good luck to you!
