Daniel you're eating far too little for your weight. Also with your bodyfat estimation I'd say you don't have a slow metabolism or you wouldn't be that low already. With all of that cardio plus only 1400 calories your body isn't getting nearly enough to survive and it will eventually go into starvation mode if it hasn't already not to mention you'll be burning off that hard earned muscle. The general rule of thumb for dieting calories is that 10x bodyweight is the absolute bottom of the range. That'd be 1800 calories minimum for you, not to mention you're doing more than average cardio which makes a greater deficit.
My recommendation is either continue your current cardio/weight training regimen and up your calories to at least 2000 or so... or shoot for the 1800 calories but drop your cardio in half. Your body reacts to a calorie deficit pretty much the same regardless if it's due to eating less or exercising more. You can eat a good amount of food but if you exercise so much that your body is starving then the result is the same as if you simply fasted.
Depending on how long you've been eating like this your body may already be starving. If it is I'd recommend taking a few days or even a week off of the diet and just shoot for maintenance calories(15x bodyweight). Then hopefully your metabolism gets back close to normal, leptin levels go up a bit and then you can drop calories to around 12x bodyweight. You should lose weight just fine like this and if it starts to slow down at some point then slowly reduce them further.
The basic idea is you can't just continue to eat less in the hopes of burning fat faster as it will backfire. There is only so much of a deficit you can create before your body reacts in a negative manner. If this weren't true then we could all fast for a week or two at a time and drop 10-15 pounds of fat that fast. Unfortunately the body senses this and will adjust the metabolism to compensate for the drop in calories. It's simply a survival method that the body has evolved over time and unfortunately for us dieters it works quite well.
The trick is simply to find the magic spot where we're in a good enough deficit to lose weight moderately fast but not too much of a deficit to trigger starvation mode. It may take time to find this spot but once you do you can shoot for it and get the best out of your diet.
