If your blood sugar or fat levels are high to start with, going all-meat might help lower them — but not everyone sees the same results, so the average change across a group might not look impressive.

What we've found so far suggests that a carnivore diet may help lower HbA1c or triglycerides in people who start with high levels. Our current analysis shows the evidence leans toward this possibility, but results can vary from person to person. We analyzed the available research and found 27.0 supporting assertions and no studies that refute the idea [1]. The main point from what we've reviewed is that individuals with elevated blood sugar or fat levels might see improvements when switching to an all-meat diet. However, because responses differ, the average change across groups may not appear large [1]. This means that while some people could experience meaningful drops in HbA1c or triglycerides, others may not see the same effects. We don’t have enough data to predict who will respond well or why the variation occurs. Our analysis does not confirm the diet works for everyone, nor does it prove long-term benefits or safety. Based on what we've reviewed so far, the evidence does not rule out benefit for some individuals, especially those starting with high levels. Still, we can’t say how likely or consistent those changes are over time. Practical takeaway: If your blood sugar or triglycerides are high, an all-meat diet might help lower them — but it’s not guaranteed, and results will likely differ from person to person.
