Metabolic & Cardiometabolic
increased meal frequency (lente carbohydrate) decreases LDL cholesterol
In plain terms: Does eating many small snacks lower cholesterol and insulin?
Unclear — one tiny seven-person study drove the early signal and later trials are mixed-to-null.

What the evidence shows
Spreading the nutrient load (17 snacks/day vs 3 meals) lowered LDL, apoB, insulin and C-peptide on identical diets — the conceptual root of 'lente (slow) carbohydrate'. But n=7 and later meal-frequency trials are mixed-to-null: treat the dramatic numbers as hypothesis-generating.

Medecine clinique et experimentale | observational | supports | moderate | Jenkins-group narrative review (1995): increased meal frequency ('nibbling') at constant calories reduces postprandial insulin secretion and lowers LDL cholesterol and apoB, consistent with the 'lente carbohydrate' concept; also notes SCFA |

No significant differences in fasting total or LDL-cholesterol, nor in fasting/postprandial insulin, glucose or triacylglycerol; HDL-cholesterol rose after gorging vs nibbling.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
