According to the Mayo Clinic, ideal HDL levels for both men and women are 60 milligrams of cholesterol per deciliter of blood. If a man’s HDL level is below 40 milligrams of cholesterol per deciliter of blood or a woman’s HDL level is below 50 milligrams of cholesterol per deciliter of blood, then disease risk, specifically heart disease, is considered to be heightened. Even if your HDL level is above the at-risk number (but below the desirable number), you still want to work on increasing your HDL level so you can decrease your heart disease risk. (9)
Resistance training is a form of physical activity that forces your muscles to contract, building up strength and endurance. Some research also shows that resistance training could have beneficial effects on heart health as well and may decrease total and LDL cholesterol. (31) Weight lifting and bodyweight exercises like squats or lunges are some examples of resistance training that you can add to your routine.
According to a study published in November 2015 in the journal Nature, a diet high in carbohydrates — like added sugar, white bread, cookies, and cakes — reduces HDL cholesterol levels, increasing the risk for metabolic disorders. Refined carbohydrates found in foods labeled “low-fat” make these just as bad as full-fat foods because the fat is often replaced with carbohydrates from added sugar and other starches.
And according to some powerful experiments by software engineer-turned-biohacker Dave Feldman, you can actually increase and decrease your cholesterol at will. It all depends on how much fat you eat — and, directly against mainstream dietary knowledge, the correlation is inverted. In other words, eating more fat will actually lower your cholesterol.
