Everyone is different so the fasting and low carb approaches may work for some, but not all. I read most of the articles on T-Nation; I browse the forums daily; and I follow a handful of training logs. @MarkKO 's log is the most detailed thing I've seen out of all of that content when it comes to nutrition. Go look at his log! You'll have to backtrack a little ways. I only started following in the past few months but he's laid out his entire nutrition plan for the next year or more. He's cut from 225 down to 180 and has a plan to add quality muscle mass over time. I think you could learn a lot from reading into his approach and looking at his transformation.
And now a different thought on your issue: are you actually measuring body fat or just looking at the photos? And if you're only using photos, do you take pics of your back and legs? You might have some subtle changes in your composition but don't notice it if you're focused on your abs. The first place you add fat will be the last place you lose it. For most men, it's the abdomen. You could be decreasing fat in your back and not notice if you're only looking at yourself in the mirror. Just a thought.
And lastly, if you're not already, take circumference measurements. I track neck, chest, abdomen, waist, hips, quads, calves, biceps/triceps, and forearms. I track abdomen for obvious reasons--I want a six pack. I track waist for the similarly obvious reason. I find that hips actually give me a measurement of my glutes. The rest are pretty common measurements. I once heard that bodybuilders strive to have equal measurements of their neck, biceps, and calves for symmetry. I have no idea if it's true lol
