Carnivore Diet success stories – with Mike


Interview with Mike

1) Introduce Yourself.

My name is Mike Lewis. I work as a medical doctor in the UK. I work in A&E and General Practice. Married with 3 grown up children and 2 grandchildren aged 3 and 1. I live in the Lake District in the UK. 

2) How did you eat before Carnivore.

I have followed a low carb diet for years. Initially the Atkins diet. He definitely had the main idea correct. He was criticised by the uninformed but I liked his philosophy. And why shouldn’t you try and make money from an idea you and your life’s work. Contrary to popular belief he wasn’t obese when he died from a head injury in 2003. 

My diet has changed over the years to paleo then ketogenic before carnivore. 

3) Why did you try Carnivore to begin with.

The evidence seemed to be convincing that the majority of plants weren’t that healthy an option. Many of our ideas about how great they were to eat are based on marketing and the factual information doesn’t match this hype. 

4) How do you personally approach the Carnivore Diet.

I started off eating mostly steak, lamb, chicken, eggs and dairy. I still drank coffee with cream initially. Then I dropped the chicken and then dairy and added in organ meats. So now I have steaks, heart and liver (mostly beef) and eggs. I eat twice a day. Still have coffee without cream though.  

5) What benefits have you seen since starting the Carnivore Diet.

Since making that change I have lost a further 8lbs and % body fat is 16.  I weigh 151 Lbs and 5’9”. Much more energy. Never had any medical issues to begin with and not on any medication. I’m in ketosis all the time but rarely check it any more. 

6) What negatives have you found with the Carnivore Diet.

None personally. Loose stools were noticeable sometimes on the ketogenic diet but ok on carnivore. My wife is not a big fan but that’s mainly because there is uncooked beef liver and heart in the fridge. I don’t eat it raw by the way. Some people do but that is not for me. 

7) Do you exercise on the Carnivore Diet, if so how do you find it and what do you do.

I am a CrossFit guy so workout most days for an hour. I would recommend this to anyone no matter what stage of fitness. Lifting heavy is probably THE most beneficial exercise you can do. 

8) What piece of advice would you give someone who is interested in trying this diet, but hasn’t taken the leap yet.

Do it. It’s simple. Doesn’t have to be expensive as you are not buying a whole load of crap to eat too. I’m hardly ever hungry and I eat twice a day in average. You don’t have to be super strict just eat when you want. You can generally eat as much as you want too. It’s almost impossible to overeat doing carnivore in my experience. And I’m 2 years in now. 

9) Do you think Carnivore will ever be accepted as a mainstream diet.

Probably not. It’s going to take several generations to change the attitudes of many, medical doctors especially. But we’ll keep putting the message out there. 

10) Anything you would like to add, and where can people follow you.

Keep reading about it. Most of all, just start. Take a load of pics before you start because you will be amazed at the changes.
