Obesity trends in the U.S. have a little connection with sugar intake

I would like to remind to the readers the outdated information presented by Dr Lustig all over again. In the video (16:05) I noticed how he again showed in 2013 the trends in obesity prevalence in the US up to year 2003-4 as the present trend:

I do not doubt the data and their value - in the past. But the more recent trends show that the obesity has been rather leveled off among adults:

The article also says that the same trend is suggested for children, too. Similar trend was observed in the UK.
Here I would like to remind you, that the sugar consumption in the U.S. has been decreasing since 2000 while you can see that the obesity kept rising.  

And, surprise surprise, Dr Lustig, after those years of presenting to you that obesity rose as the sugar consumption rose, he finally admitted in a video at 27:04 (2014) that these two variables do not quite match.

The yellow shade refers to obesity, the blue line to refined sugar, red line to HFCS and the green line to fruit juice. These are the corporate data, which he refused in my argumentation in the past as unreliable, yet he keeps showing them again when it suits him. The sugar and obesity not only do not correlate perfectly, they hardly correlate at all, especially when other sources of energy are added to the equation:


Just have a look at the time point above year 2000. Sugar intake went down, while fat intake shot up, perfectly matching the trend of rising obesity. Moreover, as the sugar consumption has been increasing over the decades, the fat went along this sugar. Quite interesting, right?
