So 26lbs in 3 months is unusual. Think of it this way, if you ate zero food (and your metabolism didn't go down for some reason) it'd take 36.4 days to lose 26 lbs of fat. So it's like going a 1000 calorie deficit (40%) for 90 days straight. The more you weigh the easier this is (because your body isn't going short, it's just eating the fat inside you already).
