Foods with cholesterol. Cut you cholesterol mg’s in half (or more) and see if your cholesterol drops after 3–4 weeks. Cholesterol is only found in animal products. So, that’s all meat, fish, poultry, milk, cheese, eggs. Look up what you eat. One egg yolk has the same cholesterol as a decent sized steak.
Also, some studies show lowering saturated fat and sugar helps too. I would do one thing at a time to know what helps your body. Less sugar/carbohydrates should lower your triglycerides significantly if those are high.
If I cut my cholesterol intake 75% my cholesterol drops 50 points in 3 weeks. That’s me, my body doesn’t know what to do with cholesterol and I pump out a ton of it also. I’m an over-absorber and over-producer. You possibly eat less cholesterol and nothing changes. It only takes 3–4 weeks to test it. Make sure you don’t eat a lot of cholesterol 1–3 days before the test.
When I was 16 and thin my first cholesterol test was 270 and my triglycerides were high. The only way you know what is working for YOU is by testing.
