Key MAHA advocate Calley Means resigned as a top RFK Jr. adviser Thursday without saying why, after years fighting corporate food interests inside the Trump administration.

Associated Press reporting carried by ABC News said Calley Means stepped down from his post with the Trump administration on Thursday. Means had served as a top adviser to Health Secretary Robert F. Kennedy Jr. and as a chief voice for the Make America Healthy Again movement.

He did not give a reason for leaving. In a statement, Means said he leaves with tremendous respect for President Donald Trump and Kennedy, and he cast the last stretch of work as only the start of a longer fight over chronic disease and a health system that profits when Americans stay sick.

“The past two years have seen historic policy and cultural change to confront the chronic disease crisis and healthcare incentives that profit from us being sick,” Means said.

“This movement is in the first inning and just getting started.”

Just The News reported the same exit and noted Means previously advised Kennedy’s 2024 campaign before moving from a special government employee role into a full-time White House job. On the way out, he pointed to work tied to dietary guidelines, removing soda from SNAP, and food dyes.

White House thanks Means as food fights defined the tenure

White House spokeswoman Allison Schuster said the administration is grateful for Means’ time and that he has done a fantastic job for the MAHA movement. An HHS representative did not respond to a request for comment.

Means came into the second Trump administration early as a White House adviser and worked from a perch at the Health and Human Services Department. He had risen to national notice by arguing that ultraprocessed foods, additives, and pesticides help drive many chronic conditions, and he brought that case into government.

From that post he went after leading physician groups, federal agencies, and government scientists, saying they protect their own interests. Senior White House officials often worried the approach would alienate the powerful food industry. Progress on food reforms was slow going.

Staff changes at the top of government always draw notice, much as recent coverage of talk about the chief of staff’s standing showed how closely personnel moves are watched in Washington.

Health activist Kelly Ryerson, a leader of American Regeneration who is also known online as Glyphosate Girl, said she was impressed Means completed more than two years at HHS fighting the food battle despite obstacles from corporate interests.

“At the heart of MAHA is a shared belief that the nation’s health must not be sacrificed to corporate profit, and that a preventable slide into chronic disease is a threat to America itself,” Ryerson said.

Ultraprocessed food definition stalled after April promise

Kennedy had promised in April the release of a first-ever government definition of ultraprocessed food. That same month, FDA acting commissioner Kyle Diamantas told a conference that defining the class “is really hard.”

By August, Kennedy staffers had suggested an announcement was imminent. The announcement that followed instead centered on a proposal for greater scrutiny of food additives, with only a passing mention of ultraprocessed foods.

Means’ heavy focus on food also frustrated other MAHA figures who wanted Kennedy to concentrate more on “medical freedom” issues, including rolling back federal recommendations and approvals for vaccines. His sister, Dr. Casey Means, a wellness influencer, author, and entrepreneur, failed to win confirmation as surgeon general earlier this year after doubts were raised over her vaccine stance.

Health personnel fights remain a live front in Congress as well, including the recent path of a CDC director nomination through a Senate panel after vaccine-related assurances were demanded.

MAHA’s food agenda met industry power and slow machinery

Means framed his exit as respect for Trump and Kennedy, not a break with the project. The public record in the resignation coverage shows a different pressure point: repeated friction with officials who feared angering food companies, plus a promised ultraprocessed definition that never landed as advertised.

That is the pattern voters were told to expect when outsiders try to reorder agencies that have long worked hand-in-glove with regulated industries. Big food has money, lawyers, and lobbyists. Bureaucracies have endless reasons to call hard problems “really hard” and move on to narrower, safer paperwork.

Administrative shake-ups elsewhere in the executive branch, including how the Trump administration moved against long-criticized foreign-aid structures, show the same basic contest: who sets priorities when entrenched systems resist.

Means spent more than two years inside that contest on food, additives, pesticides, and the chronic-disease load carried by ordinary families. He leaves saying the policy and cultural shift has begun, and that the movement is still in the first inning.

Taxpayers footing the bill for diet-driven disease did not invent the corporate incentive problem Means named. They live with it. Whether HHS and the White House keep pressing the food file without him will show if MAHA’s early gains were a start or a peak.

Chronic illness does not wait on agency timelines, and neither should the people paying for the consequences.
