10:00 One minute saying age don't slow metabolism, Then saying it does???
So what is the metabolism???
How about my bmr is 1300. So you’re saying it’s irrelevant
How about AI nutritionists ?
DR Li, WHAT SHOULD I PAIR WITH TART CHERRY JUICE before bed I’m 81.
I only eat 1/4-1/2 on my plate of proteins/veggies STILL gain weight!!!! 😡😤😠😖
Mine came down at 17% at the age of 51
Too many ads
pure BS==very little help!!!!
Dr. Li is absolutely right about the tongue being the first place to enlarge with weight gain. As we age and gain weight, the core of our head grows–the nose, the ears and the tongue. The thing most don't know is when you lose weight, these things do not go down. So the tongue is constantly getting bigger. This is why we have so much sleep apnea.
I had two sleep apnea surgeries so I could breathe. They performed a partial glossectomy and removed tongue tissue the size of the palm of my hand!
Everyone is different. This guy and his myths. Everyone is not born with the same operating system. Tell that to anyone that is born with an issue. Majority of people maybe.
He didn't answer your question about how your daughter felt.
Wow! I eat healthy but VERY STRESSED over my life. My body looks like it..not sleeping & just stressed. I will do better
we dont have the same eyesight at all what is he talking about. total bs
Mel is such a great interviewer. I love the fact that Mel asks great questions and sometimes repeats Dr’s answers in plain and simple ways that I can easily understand. Thank you 😊
How about those who dont eat enough and our bodies are in survival mode? Eating less calories is the opposite of what we need to do.
We’re not all born with the same systems. The whole foundation for his argument is not true
What kind of beans? Green beans, kidney beans, black beans??
So interesting and all true 👍🙋🏼♀️🌷
Great podcast! So many useful yet simple hacks to apply. Not counting calories have never worked for me though ( guess I am too much of an optimist in this area 😉 )
I never put cheap gas in my car.
H Mel. Kindly ask Dr. Lee if we can have fuel gauge in our body?
What kind beans? I’m assuming lentils?
There is no way around it, healthy food, good sleep, exercise, weight lifting, stress management. I also cut the 4 poisons sugar, flour, salt, and dairy products.
I don’t believe we all have the same metabolism
I look for way to my resting metabolic rate (RMR) test next month. 🎉
Thank you for posting this
