The Mexican government is introducing a tax on sugary drinks to address obesity problems, but the document finds flaws in this approach. It argues that simply taxing drinks will not directly impact obesity, which is caused by broader behavioral factors. The document claims the statistics on obesity and surveys of residents that the government cites are misleading and do not accurately prove sugary drinks are the cause. Overall, the author concludes the tax policy is not well-supported and will not effectively address the root causes of excess weight issues in Mexico.
