Blood sugar levels are not a reliable proxy for dietary sugar intake.

Tell that to diabetics

Diabetics know better than anyone that dietary sugar is not the only food that can increase blood sugar. Rice cakes have no sugar in them at all, for instance, but have a higher glycemic index than chocolate cake.

No, the reason sugar gets a bad rep is because of what it does to your body. The insulin response to sugar is the primary way your body stores fat and sugar itself is readily converted to fat. The glucose & fructose spikes are also source of inflammation. It is believed that this inflammation is the cause of some of the damage related to heart disease, etc.

Heart disease etc, including[1]: "This is why hemoglobin A1C is frequently used in studies that try to correlate blood sugar control to various disease processes like Alzheimer’s, mild cognitive impairment, and coronary artery disease. It’s well documented that glycated hemoglobin is a powerful risk factor for diabetes, but it’s also been correlated with risk for stroke, coronary heart disease, and death from other i…

Perlmutter's stuff is way out of the left field. If you read the actual study, it does not support his conclusions. Interestingly, there are studies that show that a vegan grain-rich diet lowers hemoglobin A1C. So much for his made-up "grain brain" condition. Of course most diets studied lower it, because they are much healthier than the standard american diet of overeating.

And it's also perfectly possible to be a moderate consumer of sugar and have low hemoglobin A1C depending on other lifestyle factors.

I'm getting sick of this ignorant sugar alarmism. Sugar is not the culprit behind all the diseases listed in the article. Obesity is [5] [6]. Unless of course you're talking about cavities. Then not brushing your teeth is the culprit. The reason sugar gets such a bad rep is that high-sugar foods tend to be less-filling and lead to overeating [1]. Stay at a healthy weight by controlling caloric consumption [2]. The ar…

Doughnuts, one of my favorite foods, can be part of a healthy diet Can they?

Personally, I eat a lower-carb diet of fruits, vegetables, meat, fish, and other healthy foods most of the time. A few times a year I have a doughnut. Do I have an unhealthy diet because of that?

I can confirm that from my own experience. I lost 20kg in 6 months. Yes I restricted my calorie intake. But how I did that? By controlling my appetite with avoiding carbs especially sugar. Ketogenic diet is powerful tool for restricting calorie intake.

I've been doing Keto for 5 weeks now, it's an improvement and very easy to follow. Restricting calories is definitely a good way to approach weight loss. I'm so far happy with all the results.

As long as you get the right amount of calories and nutrients, keto can be healthy long-term, as can veganism. People should chose the diet that works for them. The diet they like enough to follow.

For me, keto naturally reduces calories. I'm not the kind of person to overeat bacon or butter. I like them, but I won't overeat them. Whereas when I was vegan I found myself overeating a variety of things.

Concur. I didn't restrict my calorie intake, and lost 40lbs eating 65% fat, 30% protein and 5% carb. As soon as I add in sugar or other carbohydrates in any capacity, I gain weight and eat much more. On a ketogenic diet I rarely even think about food - I am rarely hungry.

OTOH I lost 20Kg eating lots of fruit (evil addictive fructose in there) and no meat. Any one-sided diet can work if your awareness rises. More wholesome diets might even work better in the long run.

I can one up everyone. I lost weight on an almost all-fruit diet. And also weight on an almost all-meat diet. What they had in common was simple foods that satiated me and did not impel me to overeat.

I've been part of diet communities with keto dieters for awhile and I have met people who have gained weight on keto. These people seem to not be as satiated from things like bacon as more successful keto dieters.

I eat a more diverse diet now. I stay away from foods that cause me to overeat like fries.

XYLITOL :) We use it for coffee, baking, cocktails, Sushi rice and more. Xylitol has less intensive impact on the insulin system and does not cause a glycaemic peak as strong as you experience it with sugar. Xylitol is also proven to directly prevent Caries. There are numerous studies on Xylitol and its benefits - Google is your friend. How is it possible that in a thread on sugar even after 146 comments nobody menti…

Erythritol and glycerol are also decent sugar-alcohol sweeteners.

Other types of sugar alcohols are not suitable as sugar replacements.

Methanol and ethylene glycol are poisonous. Mannitol, sorbitol, isomalt, maltitol, and lactitol will all give you horrible gas and diarrhea. To a certain extent, xylitol and glycerol will also have a laxative effect, but as erythritol is absorbed by the gut, it is the only sugar alcohol that can be consumed in excess without dire colonic consequences.

Yes, the problem with coke isn't that it's got a lot of sugar in it. The problem with coke is that people drink litres of it each day.

I can't tell if you are being sarcastic or agreeing or not. Usually your comments are good so I am going to believe you are sincere here. Somewhat related I am one of those people who needs to make a change as I get >1000 calories from soda a day. I did quit years ago (just cold turkey) and after the initial headaches and tiredness the biggest change I saw was that I was constantly hungry. Much like quitting smoking…

I'm not sure why you would think the response was sarcastic. Coke having sugar is NOT the issue. Drinking literally liters of it each day is certainly the issue. On top of a normal diet all those extra calories are bound to be a problem.

Eating? I'm only partially joking. Calories don't just magically appear.

Sugar makes you feel like you're starving. You get sleepy at the peak, "starving" at the trough... like a repeating sine wave. Leads to overeating.

It causes people to lack discipline in what they eat. That's really the issue here. Sugar isn't some poison and it is not a magical 10x the normal calorie. People who eat a lot of sugar are usually still eating a lot of everything else. All those calories add up and lead to weight problems.

The first thing to losing weight is to get serious about how much you are eating. Write it all down. People tell me all the time they don't understand why they are gaining weight, and then we go through a day of eating. It's not just sugar or fat or some other thing someone has said trying to sell a book, it is simply eating too much. Oftentimes people don't even realize it.

I had the opposite problem with I started weight lifting years ago. I simply couldn't gain weight, and thought it was impossible based on how much I thought I ate. When I started writing things down I realized I was barely breaking 2k calories/day if I was lucky. It took concerted effort to eat more, and results quickly followed. Now I'm older and am not as active, so I simply don't eat as much. My weight has stayed the same for a long time.

Dietary sugar intact/dietary carb intake - at the end of the day, it turns into sugar
