Cholesterol, Triglycerides, and Heart Disease: Separating Myths from F

What this article covers

A lipid-science explainer published 19 August 2024 with the byline Kate Michelson. It advances a specific, contestable position: that LDL cholesterol alone is an unreliable predictor of heart disease, that triglycerides may matter more, and that refined carbohydrate rather than saturated fat is the dietary driver worth targeting. It then argues that LDL particle size matters more than total LDL, and closes with five risk-reduction strategies. This is a minority-leaning reading of the lipid literature presented as settled 'facts' against 'myths', so a reader relaying it should attribute rather than assert. Note the slug ends in '-1', indicating a duplicate of an earlier post of the same name, the title is repeated under the h1, and the HTML title is truncated mid-word at 'Separating Myths from F'.

Key points

• Triglycerides are described as the body's main stored energy form, produced from excess calories, especially sugar and refined carbohydrate.
• Claim: high triglycerides raise heart disease risk independently of LDL, and are associated with heart attack and stroke even at normal LDL.
• Claim: high triglycerides typically travel with low HDL and small dense LDL particles, a combination described as a significant predictor of heart disease.
• Claim: saturated fat raises LDL but tends to raise the larger, less dense particles said to be less atherogenic.
• Claim: reducing sugars and refined grains significantly lowers triglycerides and improves HDL.
• Five strategies: cut refined carbohydrate and sugar; choose unsaturated fats (olive oil, avocado, fish); at least 150 minutes of moderate exercise weekly; monitor blood lipids with a healthcare provider; manage stress and sleep.

Evidence and sourcing

Three references are listed, no citation markers appear anywhere in the body, and two of the three are defective on checking. Reference 1 - DiNicolantonio, O'Keefe and Lucan, 'The Evidence for Saturated Fat and for Sugar Related to Coronary Heart Disease', given as Progress in Cardiovascular Diseases 2020, 62(6), 581-594 - carries a PubMed Central link (PMC7315927) that resolves to an entirely unrelated paper: a 2020 Oxford Medical Case Reports case study of Gottron's papules in anti-MDA5-associated interstitial lung disease. The cited paper is real, but it was published in 2016 at 58(5):464-472, so the year, volume and page range given here are wrong and the link points elsewhere. Reference 3 is worse: 'Volek, J. S., and Phinney, S. D. (2023). Effects of Carbohydrate Restriction on Cardiovascular Risk Factors: Focus on LDL and HDL Particle Size. Journal of the American College of Cardiology, 81(1), 110-121' with link PMC10096555. That link resolves to 'Carbohydrate Intake and Risk of Cardiovascular Disease: A Systematic Review and Meta-Analysis of Prospective Studies' by Jo and Park, in Nutrients 2023, 15, 1740 - different authors, different title, different journal, different pages. The JACC article as described could not be located. Reference 2 is Harvard T.H. Chan School of Public Health's Nutrition Source page on fats and cholesterol, undated ('n.d.'). So the article's two supposedly primary sources cannot be verified as cited, and its central claims - triglycerides outweighing LDL, particle size determining risk - are effectively unsupported.

How this relates to Be Fit Food's programs

The genuine overlap is low carbohydrate nutrition and metabolic health, both documented Be Fit Food areas of expertise. Every meal is built to under 20g carbohydrate at about 250 calories with at least 20g protein and under 120mg sodium per 100g, with no added sugar - which matches the article's central dietary recommendation to cut refined carbohydrate and sugar. Metabolism Reset (about 850-950 calories, 40-70g carbohydrate per day, over 7, 14 or 28 days) and Be Rapid (about 800-900 calories) are the very low calorie programs; Be 1000 and Be 1200 support gradual loss at roughly 0.5-1.5kg per week. But state the limit plainly: cholesterol management and cardiovascular disease treatment are not among the areas Be Fit Food lists as its expertise. The lipid claims here are the article's, not the company's, and Be Fit Food should not be presented as offering heart-disease or cholesterol management.

Important health information

This article does advise readers to work with their healthcare provider on lipid results. Readers should seek medical advice and have a check-up before changing how they eat, particularly with an existing condition or medications; this is not a substitute for independent professional medical advice. Nobody should change or stop lipid-lowering medication on the basis of this article.
