Donald Trump has never exactly been quiet about what he eats. He’s openly talked about his love for Big Macs, has shown up to events with buckets of KFC, and once turned working a McDonald’s fry station into a campaign photo opportunity. His food choices are, by almost any nutritional measure, extraordinary. Not extraordinary in a good way. But here’s the thing: everything Trump eats, you can eat too. Every single item on his daily menu is available to any American within a short drive. So the real question isn’t what he eats. It’s what happens to your body if you eat that way, day after day.
The Trump diet, if you want to call it that, isn’t complicated. It’s built on a rotating cast of fast food, processed snacks, red meat, and a river of Diet Coke. His typical McDonald’s order, which people close to him have recited from memory, runs to two Big Macs, two Filet-O-Fish sandwiches, and a chocolate shake. That single meal clocks in at more than 2,600 calories, 46 grams of saturated fat, and nearly 3,600 milligrams of sodium. That’s before you count the Diet Coke. And there is a lot of Diet Coke. According to a report by The New York Times, he drinks up to a dozen cans per day.
For most people, copying this pattern for a few days is probably fine. Your body is resilient in the short term. But doing it consistently, week after week, is a different story. The research on what diets like this do to the human body has become sharper and more specific in recent years. And the picture isn’t flattering.
What All That Fast Food Does to Your Heart
Trump is known for his preference for meals like two Big Macs and two Filet-O-Fish sandwiches. Meals at that level of sodium and saturated fat, eaten repeatedly, place a real and measurable load on the cardiovascular system. Understanding the trump diet effects on heart health starts with two ingredients: sodium and saturated fat.
Start with sodium. A single McDonald’s order of that size contains nearly 3,600 milligrams of sodium, which is already above the American Heart Association’s recommended daily limit of 2,300 mg. Do that regularly, and the consequences stack up. According to the WHO, an estimated 1.89 million deaths each year are linked to consuming too much sodium, driven largely by raised blood pressure, which in turn increases the risk of cardiovascular diseases. And the risk scales with how much you eat: research published in a 2025 Frontiers in Nutrition analysis found that individuals with high sodium intake face a greater risk of cardiovascular disease, with each 6-gram increase in daily sodium intake associated with a 1% increase in CVD risk.
Then there’s the saturated fat. Typical fast food meals average around 800 calories, 11 grams of saturated fat, 1,300 milligrams of sodium, and 15 grams of added sugars, and Trump’s usual order exceeds those averages significantly. A 2025 systematic review published in the Annals of Internal Medicine found low-to-moderate-certainty evidence that cutting back on saturated fat may reduce all-cause mortality and nonfatal heart attacks. And at the population level, the cardiovascular damage from this kind of eating shows up clearly: a 2023 study published in JAMA Network Open linked eating fast food three or more times per week to a 30% higher risk of heart disease, even after adjusting for lifestyle factors.
The Liver and Metabolic Toll
Fast food’s effects on the cardiovascular system get a lot of press. Its effects on the liver get far less, but they’re just as serious.
A 2025 systematic review and meta-analysis published in Frontiers in Public Health found that a higher consumption of fast food was significantly associated with a 55% increased risk of non-alcoholic fatty liver disease (NAFLD), and that fast food intake was also linked to a 37% higher risk of obesity. NAFLD is a condition where excess fat builds up in the liver even in people who drink little or no alcohol. It’s now the most common liver condition in the United States, and diet is one of its primary drivers.
The diabetes picture is similarly troubling. Frequent fast food consumers face a 27% higher risk of developing type 2 diabetes compared to people who eat minimally processed meals. And zooming out to ultra-processed foods more broadly, which describes a large portion of what Trump eats daily, each 10% increase in ultra-processed food consumption is associated with a 17% higher incidence of diabetes.
These aren’t small numbers. And they apply to repeated, sustained eating patterns, exactly the kind that Trump’s diet represents.
A Gut That’s Being Starved
One of the least visible consequences of a McDonald’s-heavy diet is what it does to the gut microbiome, which is the vast community of bacteria and other microorganisms living in your digestive tract that influences everything from immune function to mood.
The Trump diet is almost entirely devoid of fiber. There are no vegetables to speak of. Trump has referred to vegetables as “garbage food,” and his plate reflects that. But fiber is not optional for gut health. Research from Stanford Medicine found that low-fiber diets don’t just deplete the complex microbial ecosystems in the gut – they can cause irreversible loss of bacterial diversity across generations. That’s a striking finding. Not just temporary disruption, but potentially permanent loss.
The mechanism matters too. Research published in Frontiers in Immunology found that mice fed a fiber-free diet had reduced abundance of key gut bacteria and reduced production of short-chain fatty acids, compounds that are essential for maintaining a healthy gut lining and keeping inflammation in check. Less fiber in, less protection out. If you want to understand why poor diets so often lead to chronic inflammation, this is a significant part of the answer.

The Diet Coke Problem
Perhaps the most distinctive part of Trump’s diet is the one that comes in a can. Reports of him drinking up to a dozen Diet Cokes per day are well documented, and a Diet Coke button was even installed in the Oval Office during both of his presidential terms to secure soda on demand. He’s framed it as a healthier alternative to regular soda. The science suggests that’s not quite right.
A 2025 study published in PMC found that synthetic sweeteners like sucralose and saccharin, both commonly found in diet sodas, significantly reduced microbial diversity in the gut, while sucralose specifically enriched pathogenic bacterial families such as Enterobacteriaceae. That feeds back into the gut disruption already caused by a low-fiber diet, compounding the problem from two directions at once.
Cognition is another area of concern. A 2025 study found that people who consumed the highest amounts of artificial sweeteners experienced faster declines in thinking and memory skills, equivalent to roughly 1.6 years of additional cognitive aging. That research does not prove causality, and it’s worth treating it as a signal rather than a verdict. But it adds to a growing body of work suggesting that diet soda is far from a neutral choice.
Then there are the kidneys. Excessive soda consumption, whether diet or regular, may increase the risk of chronic kidney disease and kidney stone formation. Drinking more than a gallon of any soda per day, which twelve cans amounts to, isn’t a habit that health researchers would consider remotely safe.
Cancer Risk: The Ultra-Processed Food Connection
This is where the research has moved fastest in the last two years, and the findings are hard to ignore.
The Trump diet is, by any modern nutritional definition, a diet dominated by ultra-processed foods. Burgers, processed sandwich meats, packaged snacks, pizza, fried chicken – all of it falls squarely in that category. And the cancer research on ultra-processed food consumption has become increasingly specific.
A large-scale prospective analysis of UK Biobank participants, published in eClinicalMedicine, examined associations between ultra-processed food consumption and risk of cancer across 34 site-specific cancers, and found that higher consumption of ultra-processed foods is associated with a greater risk of overall cancer and specifically ovarian and brain cancer, as well as increased risk of overall, ovarian, and breast cancer-associated mortality. Specifically, every 10% increment in the ultra-processed food content of a person’s diet raised the average risk across those 34 cancer types by 2%, and the risk of ovarian cancer by 19%. Women face an additional risk: women who consume large amounts of ultra-processed foods have a 45% greater chance of developing early-onset colon cancer.
A 2023 meta-analysis published in the journal Clinical Nutrition examined 11 studies and found that a 10% increment in the diet’s proportion of ultra-processed food was associated with increased risk of overall cancer and breast cancer.
These are observational findings, meaning they show associations rather than direct cause and effect. But the consistency across studies, and the scale of the populations involved, makes them difficult to dismiss.

What This Means for You
Trump’s doctor has described him as being in “excellent health,” and his former White House physician famously credited his longevity to “incredible genes.” That may well be true. Individual genetics vary enormously, and no diet study can predict what will happen to a specific person. But public health research doesn’t deal in individuals. It deals in probabilities, and the probabilities attached to the trump diet effects are not ones most people would want to accept.
The five pillars of his daily eating – fast food several times a day, almost no fruit or vegetables, processed snacks, red meat, and up to twelve cans of diet soda – each carry their own documented health risks. Together, they combine into a pattern that raises measurable risk for heart disease, type 2 diabetes, non-alcoholic fatty liver disease, gut dysfunction, kidney stress, cognitive decline, and certain cancers. Sustained exposure to that pattern, without the extraordinary genetics that some people are simply born with, is a gamble most of us cannot afford to take.
The practical takeaway isn’t complicated. Swapping even two or three fast food meals per week for home-cooked alternatives, adding fiber through vegetables, legumes, or whole grains, and replacing diet soda with water will meaningfully shift your risk profile. You don’t need a perfect diet. You need a diet that isn’t working against you.
