They eat too many carbs IMO. As many of us do, I was diagnosed with high cholesterol around 50. I began eating vegetarian. I did include some dairy, so not technically vegan. After a year, my lipid profile and my blood sugar were worse. I now had high cholesterol, high LDL and was pre-diabetic. After some research, I decided to cut carbs and add lean meat and eggs back into my diet. I lost weight and my lipid profile is now fabulous. Total cholesterol just over 100. For me, there is a definite link between carbs and metabolic issues. There appears to be no link for me between dietary fat and metabolic issues.
My wife also said I needed to lose some weight. She said a doctor where she worked had lost 40 lbs. on the Atkins diet. So she bought me the book and I read it and started my new way of eating.
Within 4 months I had lost 42 lbs. I felt great. Who wouldn't when you get to eat steaks, hamburgers, chicken, and pork chops all the time? I loved it.
Eventually, I lost a total of 85 lbs. that year and continued on this new way of eating.
On my next annual visit, my doc looked at me and wondered if I was the same guy. He said I was the first patient who he had told to change their diet because of diabetes, who had actually followed through and lost weight.
All of my lab work was back within normal ranges. My cholesterol was 110. I felt 20 years younger.
And all I did was to ignore what the government approved food pyramid told me to eat. I turned the pyramid upside down and ate more meat, fats and simple carbs. I completely quit eating processed carbs. That's the secret.
We don't get fat from eating fat. We get fat from eating too many processed carbs and then not burning them all off with exercise and daily activities. Those carbs convert to glucose and that's what fueled my day. Whatever I didn't burn was stored as fat and I gained weight over the years.
Not eating processed carbs forces your body to look elsewhere for fuel and it starts burning your fat stores.
Not eating vegan has made me healthier, reduced my weight and made me feel like I was young again.
It's disturbing that this research team and the global environment loonies want us to eat more processed carbs to save the planet from climate change.
Political agendas are not good for your personal health. I'll continue to eat meat.
