After having a heart attack in 2016, Greg, 59, from Australia, made several attempts to lose weight and improve his health by following a low-fat, low-calorie diet. To his great disappointment, it didn't seem to help.
But two years later, Greg's daughter introduced him to a dramatically different approach: a keto diet. After doing some research, Greg decided to give it a try. Can you guess what happened to his cholesterol and weight?
In this interview, which has been lightly edited for length and clarity, Greg shares his experience with keto.
How did you discover keto?
In Feb. 2016, I had a heart attack followed by angioplasty and stenting (medical procedures that help restore the blood flow in the blood vessels). I was a little bit overweight, and so, my doctor encouraged me to follow a low-fat, reduced-calorie diet to lose weight.
After several unsuccessful attempts to lose weight, my daughter suggested I try a ketogenic diet. I didn't know much about keto, but found some good information on YouTube from a Low Carb Down Under conference that had been recently held in Australia. I listened to speakers like Dr. Tim Noakes, Ivor Cummins, Gary and Belinda Fettke, and Dr. Paul Mason. And at last, my health issues all started to make sense!
My presumption about metabolic syndrome, type 2 diabetes, obesity, and so on, was turned on its head.
My presumption about metabolic syndrome, type 2 diabetes, obesity, and so on, was turned on its head. And with a much clearer and more satisfactory explanation, I started a keto diet in 2018.Did you have any health struggles before going keto?
Other than heart disease, I was about 35-45 pounds (15-20 kilos) overweight. I took medications for high blood pressure and high cholesterol.
What were you eating before going keto?
Before starting a low-carb lifestyle, I was eating what I thought was a reasonably healthy diet. My diet included lots of carbohydrates like bread, rice, pasta, and whole-grain cereal. I also ate quite a lot of fruit and some vegetables, meat, and dairy.
In what ways has your health improved since starting keto?
I have successfully maintained a low-carb diet and a loss of approximately 33 pounds (15 kilos).
My HDL has increased by 73%, my triglyceride levels have decreased by 50%, my LDL/HDL ratio has decreased by 24%, and my inflammation is way down (with an hs-CRP at 0.3 mg/L).
I feel much better, I have more energy, and my sleep has improved!
I feel much better, I have more energy, and my sleep has improved!What does a typical day of eating look like for you now?
For most of 2018, my keto diet evolved as I found low-carb foods I liked. By the end of 2018, my diet had become what I refer to as a very-low-carb-keto-carnivore diet.
These days, I generally fast for about 16-18 hours per day with an eating window of 6-8 hours.
I start the day with about 1 quart (1 liter) of water and a milk coffee with 1/2 cup (or 150 ml) of milk, plus some cod liver oil tablets.
About two hours after my coffee, I eat a larger meal that consists of some combination of bacon, eggs, steak, chops, sausage, pork, chicken, fish, and cheese. I cook it with olive oil, butter, or ghee, and I eat until satiated.
A few hours afterward, I have a small serving of some combination of cheese, avocado, dark chocolate, frozen berries, milk, nuts, and leftovers from my main meal.
I don't eat any vegetable oils, bread, cereals, rice, pasta, fruit, or vegetables.
Have you learned from any mistakes you made on your journey?
I'm not sure I would say I've made mistakes, but I have learned a few things along the way:
- It takes quite a few weeks to transition to a low-carb way of eating, and the keto flu is real. Be prepared and don't give up.
- When I first started low carb, I tried to find low-carb alternatives to the foods that I had been eating before. For example, I tried to make low-carb bread and find low-carb alternatives to rice and pasta. In retrospect, I think it would have been better to find new low-carb foods that I liked instead. And over time, I realized that I love meat, so I began eating more of it and moved towards a keto-carnivore diet.
- It's important to listen to your body, and learn about how your body changes as you start your low-carb journey. As I progressed further on low carb, my appetite, taste, and metabolism changed and I made adjustments. For example, I added more salt to my food and adjusted my intake of animal fats over time.
- Intermittent fasting is easier when you eat to satiation. It's better for me to have one big meal rather than two or three smaller meals.
Do you think exercise is necessary for low-carb success?
I do exercise somewhat regularly, and play tennis two or three times a week. However, the amount of exercise I do is roughly the same as before I started low-carb eating. So no, I don't think exercise is necessary for success on low carb, but I do think at least moderate regular exercise is beneficial for overall health.
What are your top three tips for someone just starting out eating keto?
- Understand how the low-carb diet works for weight loss and metabolic health. That will help you stay motivated and on track.
- Be prepared and do your research. There are lots of good resources, like Diet Doctor, on the internet and on YouTube. Find an expert you like and follow them.
- Find low-carb foods you like and eat to satiation.
Comment
Congrats on your progress, Greg. Your story shows how "low-carb" does not mean just one thing, but instead it can take on many different variations. I am glad to see you found one that worked well for your lifestyle. It also sounds like you found physician mentors to help you along your path which is important. Keep up the good work!
