Morbidly obese w/ treated sleep apnea. No CardioV disease other than high bp/cholest. Will losing weight remove fat around the heart, unclog arteries?

Yes. Weight loss can reverse fat deposits both under the skin and in/around the vital organs. Be sure to eat lots of fruits and veggies. Eat healthy fats like salmon, nuts, seeds, olive oil, avocado, etc. Increase protein, especially lean and plant based proteins. Skip soda, processed foods, highly refined carbs & restrict sugar. Ask your doctor if weight loss surgery is appropriate.
