Although oil or butter is high in calories, it is very slowly digested and surprisingly does not significantly increase your blood sugar. It makes vegetables taste better and can improve the absorption of certain vitamins and the essential vitamins A, D, E & K are only found in certain fats & oils. Avoid foods containing trans-fats (usually processed foods). Use oils such as olive oil, rapeseed oil or coconut oil. It also helps you feel full for longer so be more generous
Lunch: pat dry chicken and cut into cubes. Lightly (!) salt and pepper. Heat a skillet over medium heat, once hot add coconut oil and fry chicken cubes until brown from all sides. Remove chicken, and add crushed garlic, curry paste and fish sauce to pan. Stir until fragrant and remaining oil in pan and curry paste are well combined. Then add coconut milk and whisk until well combined. Simmer and reduce sauce until desired consistency (1-3 minutes). Pour sauce over chicken and sprinkle with sesame seeds. Serve with baby spinach.
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.
I personally don’t count anymore as I want this to be as easy and sustainable as possible. I have had years of counting calories and points, and this is incredibly liberating. I just don’t eat any sugars, grains or high carb foods any more so I am incredibly low carb all the time. When I was starting out I counted, just to see where my carbs were coming from and it was an eye opener. And yes you are correct, to go into ketosis anywhere between 20-50g carbs/day. Find out what works for you.
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.
