Some take this trend even further, eating only red meat like steak or beef for every meal. While that might sound appealing to meat lovers, doctors warn it’s far from ideal for your long-term health.
Of course, meat can have a place in a well-rounded diet, especially lean proteins like chicken or turkey. But fans of the carnivore diet insist they’ve seen major health improvements — from clearer skin to more energy — even without fruits or vegetables in sight.
So, what really happens to your body when you ditch everything but red meat? According to National Geographic, it starts with some major metabolic changes. Because you’re not eating carbs, your body turns to glycogen — a stored form of glucose — for energy. This leads to initial weight loss, but most of that loss is water, not fat.
Many people are excited by that early drop on the scale, but the truth is, it’s temporary. Once the glycogen is gone, your body has to adjust again and find another fuel source.
That’s why during the first few weeks, people on a red-meat-only diet often believe they’re making real progress — their bodies look leaner, and the scale shows weight loss. But much of that is the result of water and fat depletion, not necessarily better health.
As time goes on, your body starts to feel the absence of essential nutrients, and those early wins can quickly turn into long-term problems.
This lack of fiber can cause constipation and other uncomfortable digestive issues, making everyday bathroom trips more difficult. While the diet may make your body look slimmer, it deprives your organs of nutrients they rely on, which can harm your health over time.
In short, the carnivore diet might give you short-term results, but your gut and metabolism can take a serious hit in the long run.
Meanwhile, your brain depends on a steady flow of nutrients to stay sharp, and without a variety of foods, your mental health can take a hit. Many people report lower mood and fatigue after long periods of following restrictive meat-based diets.
Cardiologists have also warned that consuming too much red meat can raise your chances of heart disease by more than 50 percent and even double your risk of stroke. So while the diet might make you look leaner for now, it can quietly damage your health in ways you may not see until years later.
