The Claim
In four obese adults consuming a protein-sparing modified fast plus 100 grams of glucose for three weeks, yellow fever immunization was associated with a significant increase in serum glucagon on day 1, while insulin, lactate, and ketone levels changed in response to the combined dietary intervention, indicating that the metabolic response to mild infection varies with dietary composition.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In four obese adults on a specific low-protein, high-glucose diet for three weeks, receiving a yellow fever vaccine caused a measurable rise in glucagon levels on day one, and altered insulin, lactate, and ketone levels, showing that dietary composition changes how the body metabolically responds to infection.

When a person eats a lot of sugar while on a low-carb, high-protein diet, their body stops making ketones and releases more insulin. When they get a mild infection like a vaccine, the pancreas releases more glucagon to keep blood sugar up because insulin is already pulling glucose into cells and ketones aren't available as backup fuel.
What the research says
1 studyWhen obese people ate a low-carb, high-protein diet with extra sugar and got a yellow fever shot, their body made more glucagon — a hormone that raises blood sugar — but only because of the sugar. Without the sugar, different hormones changed instead. This shows what you eat changes how your body reacts to a vaccine.
