Pure sugar may have peaked, but total calorie intake is still much higher than it was in 1970. Pew[1] has it 23% higher, which corresponds reasonably well to the rate at which weights have been increasing[2] over the past few decades (i.e., at about 3-4%/decade). The data is reasonably consistent with weight increasing ~linearly with calorie intake.
