That video was very informative, I was familiar with how the insulin/glucose/sugar process works, but that simplifies it for everyone to grasp.
As I posted earlier, a lot of sugar intake (specifically processed sugar and high fructose corn syrup is toxic), but some is unavoidable if you eat fruits, vegetables and other carbs.. Did you see how he specifically pointed out that some cultures who eat a lot of rice and potatoes and other big carbs are not insulin resistant?
The insulin resistant issue is huge in America. Why? I think the problem is not enough exercise and too much processed sugar. Doing this and eating lots of carbs compounds the problem. A low carb diet will help alleviate the issue, but so would plenty of exercise and reducing sugar, the real cause.
I was hanging out with a friend for a couple of weeks. They had been diabetic at one point and by watching sugar intake and plenty of exercise the problem was cured, no more diabetes! They monitored their glucose level with a blood analyzer and checked mine repeatedly, fasting and an after meals. Completely normal. Had a check up a few months ago, A1C and glucose levels normal.
OK, are you ready for this? I eat 250 grams of carbohydrates every single day! 125 grams of protein and about 90 grams of fat. My diet is fairly strict and I do not eat meat, fish or chicken. My waistline is 31" and you can still see my abs.
How is this possible you might ask? According to the Keto philosophy this can't be possible or healthy...
Exercise!!! Plain and simple, it all boils down to fitness and a healthy metabolism. Bicycle rides 3 times a week, running 3 times a week, and weight lifting 5 days a week. Wait, who has the time to invest in all this? My workouts are under 30 minutes and my bike riding and running are 15 - 20 minutes. All very intense and vigorous, only 4 to 4.5 hours a week total. I can easily gain or lose weight by adding or subtracting a few calories everyday. I practice intermittent fasting and reach ketogenesis every single day (yes, this is possible).
Low carbs is not the only way to burn fat and control blood sugar and insulin along with avoiding insulin resistance.
It's a matter of simple math, burn the carbs you intake with physical activity. You can either exercise and maintain a healthy metabolism to do this, or cut way back on carbs and risk not having a balanced diet.
I can see if one had serious physical limitations, excercise could be difficult and lowering carb intake might be the only option. But just being old or having a few aches and pains is no excuse for not staying fit, it doesn't stop me...
Just my philosophy on the whole thing, maybe not right for everyone, but works for me and I have a ton of energy. Just like someone mentioned people are ready to dismiss a full Keto regimen without trying it, who is willing to maintain a strong metabolism and high fitness level that includes eating lots of carbs? How would that feel?
C'mon low carb dieters, grab your bicycle or running shorts and just try to run me down...
