Is keto bad for your heart?  The keto diet is a high-fat, low carbohydrate plan that has been shown to help with weight loss and blood sugar control. Some studies do show positive short term effects, but there are also concerns about heart health when on this type of eating habit, which could lead you to have diabetes or another condition in the future because it may affect your cholesterol levels greatly over time if not monitored properly by an experienced doctor.

Four ways to lower your LDL and avoid high cholesterol in keto?

1) Limit the fat you add in your coffee

Avoid or at least reduce adding butter, coconut fat, or MCT oil to your coffee when you are not hungry. This has been found to help normalize elevated keto cholesterol levels.

2) Try an intermittent fasting diet

Intermittent fasting can help reduce cholesterol levels. You should only eat when hungry.

3) Eat more unsaturated fats than saturated fats

Omega-3 fatty acids found in fish and avocados (healthy fats) are great sources for lowering your LDL cholesterol levels. This healthier alternative can make a difference by reducing saturated fat.

4) Increase your carbs

Consider whether a more liberal low-carb diet (e.g., 50–100 grams of carbs per day) by increasing your carbohydrate intake. You may find that it also lowers cholesterol levels.

Do cardiologists recommend the keto diet?

The keto diet has been called a “mistake” that leads people away from healthy eating and instead toward nutrient-deficient foods.
