Firstly take a look at the cholesterol myth page, that will explain how it is the carbohydrates in your diet which makes you at a higher risk of heart disease than your fat intake, and secondly meat is one of the most nutritious foods you can have. Sure if you want to give up meat for ethics and personal reasons, but not for your health. Take a look at Zoe Harcombes fabulous post on that subject. By lowering your carbs (and processed foods) you will lower your blood pressure and improve you cholesterol profile. It’s not about how much cholesterol you have, but what type.
Use fat as a lever. We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.
