I'm not losing weight

This can be a lot of things. To me, it sounds like you're not eating enough. The human body is very good at storing energy; once you get down to to low body fat percentages, it starts getting slightly harder to shed weight. For the amount of cardio you're doing, you probably need more carbs than 20% too.

I'd plug your numbers in here and adjust your calories to match your activity level and see what happens: http://iifym.com/iifym-calculator/

Sometimes, your body just hits a metabolic stall too. You could also try adding a re-feed day or two into your weekly routine to shock your system. http://www.bodybuilding.com/fun/sclark60.htm

Make sure you're not just looking at the scale too; the mirror is your best friend here.

Oh, and, if you're primary source of exercise is baking / mainly cardio activities, try mixing in some strength training as well. Exercising in the anaerobic heart rate zone is going to assist with weight less compared to strictly cardio on it's own.

you are most welcome. 143c is probably about right for your weight, especially with how much cardio you're doing. <60g per day and you're going to be approaching ketosis (a metabolic state where your body starts processing essential fats for energy instead of carbohydrate by virtue of low glycogen levels).

How's your energy level? Do you often feel tired, run down, etc? That's another sign you're not getting enough carb intake.

Try a gradual increase if you're concerned - up your intake by 20g carbs every 3 days or so until you hit the 143 mark - that'll give your metabolism time to adjust. Then, wait at least 7-10 days to see the results, and you'll probably start losing again.

Also, I would pick one set day a week and weigh yourself then. With the increased carbs, you may notice a small spike in weight; don't be freaked out by that, it's just water/glycogen weight.

And lastly, definitely trust the mirror more than the scale. As an example, I didn't lose weight for 3 weeks once, when I used to average 1-2lbs/per week, and I was doing cycling every day + gym every single day doing intense weight lifting, etc. What was happening is I was losing fat around my thighs but putting it right back on in the form of muscle. (muscle is more dense than fat, so it weighs more on a volume/lb basis). It was actually kinda fun, I could visually see it happening in the mirror, even though the scale didn't budge.

But I would definitely incorporate some weight lifting if you can. It's really easy for your body to get used to a lot of cardio, so mixing up your routine is important.

There is no such thing as right or wrong food..Its all just a vehicle to get energy into your body. No different from a battery. From a health perspective macros matter, but from a weight, its all calories in, calories out.

How are you measuring the portions you eat?

I think the most likely cause is that you you aren't at a very large deficit. The only way to be accurate is to buy some scales, and weigh it all in grams. Guestimating how much of a portion you have eaten is simply not accurate enough. Its fine for vegetables, but for high density items like bread, meat, oils, cereal it just does not work
