Whether people eat a lot or a little dairy while dieting, their blood levels of inflammation markers and hormones like insulin and leptin change the same way—dairy doesn’t make a difference.

Scientific Claim

In overweight and obese adults on a 12-week energy-restricted diet, circulating levels of inflammatory cytokines (IL-1β, IL-6, IL-8, TNF-α, hs-CRP) and metabolic hormones (leptin, adiponectin, insulin, glucose) do not differ between those consuming 3–4 servings of dairy per day and those consuming ≤1 serving, despite overall reductions in inflammation and insulin due to weight loss.

Original Statement

“No significant dairy treatment differences were observed in the... circulating inflammatory cytokines Il-1β, Il-6, Il-8, and TNF-α, and hs-CRP... Fasting insulin changed over time with a decrease of about 12% associated with weight loss. No significant difference was observed between treatment groups or over time for leptin or adiponectin.”

Randomized Controlled Trial

Human

2011

People who ate more dairy while losing weight didn’t have different levels of inflammation or blood sugar hormones than those who ate less dairy—both groups improved the same amount just from losing weight.

Similar Assertions

Eating more dairy while dieting doesn’t reduce inflammation in fat tissue—both groups had the same levels of immune cells and inflammatory signals in their fat.

88%

Eating more dairy doesn’t make your body burn more calories at rest—your metabolism stayed the same whether you ate a lot or a little dairy while dieting.

78%

Eating more dairy while dieting didn’t make bad cholesterol go up or good cholesterol go down—it didn’t hurt heart health markers at all.

77%

When overweight or obese people eat fewer calories and either eat a little dairy or a lot of dairy, they lose about the same amount of weight and belly fat—dairy doesn’t help them lose more.

76%

People who ate more dairy didn’t move more or less than those who ate less dairy—both groups were equally active, so activity levels didn’t affect the results.
