Unless Elon is keeping fat people from ultra processed foods, this is the wrong link.
You probably meant paper published in the The Lancet which is an unvalidated study.
This study author acknowledges that: "Despite the US Agency for International Development (USAID) being the world's leading donor for humanitarian and development aid, there is scarce evidence in the literature assessing its impact on global health. Few evaluations have attempted to estimate the effects of USAID funding on maternal and child mortality in selected low-income and middle-income countries (LMICs), and some reports have offered only approximate estimates for specific diseases."
And that ", this study is the first comprehensive analysis to assess the impact of total USAID funding"
So we have scarce evidence USAID impacted anything for twenty years, yet now this unvalidated study suggests through statistical analysis its absence has caused mass deaths.
