Hmmm, good question. 20g net carbs is pretty low already as is the 1300 calorie intake. I can't really see that going much lower would have a significant impact. You might try changing things up a bit and experimenting. Perhaps your body has become accustomed to your current eating habits and a change might flip the switch. If possible you might try increasing your exercise level in order to burn more calories. I would suggest that whatever you do try to make just one change at a time; otherwise, it is difficult to know which specific change had an impact. Good luck!

Are you sure you're logging correctly? With a scale? Including all oils you cook with? Every little taste or bite you have of something?

I'd say that you either need to tighten up your logging, or you need to cut your calories. You appear to be eating at maintenance. If you cut calories further, I'd recommend that you run it past your physician first, though. Your calories are quite low already.

I'm actually opposed to increasing activity to lose the additional pounds. If you don't keep up that same activity level you'll just gain the weight back if you drop back to your regular activity level. Any increases to your activity level should be something you're ready to commit to for life (imo).

For me, and this is completely anecdotal and not backed up by any science, I find if I give my body a break it seems ready to get back to weight loss when it is over.

In late September and early October my losses were slowing and I was getting some dieting fatigue. I stayed low carb but my carbs went up into to the 30-50g zone. I thought I was in ketosis but I had slipped out of it, or it was very weak.

Anyways, instead of eating 1500 calories per day, I was eating well over 2000 calories per day, often up to 2500. I didn't lose more than a pound (at the most) in that month.

A week or two ago, I started some fat fasts for a couple of days (<600calories per day in fat only) and used intermittant fasting somewhere between 18:6 and 22:2 on most days. I was back to 1400-1500 calories per day except on fat fast days.

It think my body just needed that break because I have lost 5 lbs in less than 2 weeks so I am only 10lbs above goal now (140 lbs at 5'8", aged 42). I'm sure some it water weight, but I don't care. I dropped to 150.0 from bouncing between 155-156 for weeks.

I noticed this happened a few years ago too when I was losing weight (on a lower carb "clean" diet). If I splurged for a day or two - nothing excessive but at or above maintenance - I would lose a few pounds when I started up again. A "whoosh".

It happens fairly consistently for me, and I have no idea why. It could be something to consider. A break (more calories, more carbs, or less exercise) for a few days and then start again, perhaps even a bit harder than before for a few days with fewer carbs, calories, fasting or IF.

Good luck!

Try calorie cycling for a bit. Eater lower a few days of the week and a bit higher on the other days. For example on Saturdays I often eat 2000 calories, coz life, but then during the week I'll have several days where I'm a couple of hundred under my target. I think there's alot to be said for mixing it up a bit, especially if you've been restricted for 2 and a half years, your body does learn to adjust to a set amount of energy intake. If this amount is the same every day, your body is very good at accepting this as the new normal and holding on to your current weight. You could also try eating more for a week or two and then dropping the cals back down.
