Nobody with 30% bodyfat needs to concern themselves thinking about AMPK, mTor, or any other minutia like that. Simply thinking about calories, protein, carbs, fat, weight training, and cardio is sufficient.
This still tells me your eating is all kinds of fucked up. You're constantly varying your intake plus or minus 2,000 calories throughout the week. Some weeks, you're eating 1,600 one day, 2,100 the next, and 3,500 the next. The week before, you had 1,500 calories, 3,200 calories the next day, then 1,200 calories the day after.
Never mind that it seems like you've on extremely low calories for someone your size, for a long time. Your metabolism is probably shut down in panic mode because you've averaged 1,900 calories through all of March and April. That's roughly bodyweight (in pounds) x 7. Most coaches recommend never going below bodyweight x 10 when losing fat.
You need to work on being consistent with the basics. Try bodyweight in pounds x 13 calories for 14 days straight, while lifting 3-5 days a week and doing some kind of cardio 3-4 days a week, and see what happens.
Also, like squirrel said, what do your workouts look like? The weights (days, exercises, sets, and reps) and cardio.
