Should You Go Light Or Heavy On Carbs?
Carbs: critical for energy, but not all created equal. Low-carb diets have pros and cons. Science says moderation is key.
Carb-Strong or Carb-Wrong?
We asked you for your health-related view of carbs, and got the above-depicted, below-described, set of responses
- About 48% said “Some carbs are beneficial; others are detrimental”
- About 27% said “Carbs are a critical source of energy, and safer than fats”
- About 18% said “A low-carb diet is best for overall health (and a carb is a carb)”
- About 7% said “We do not need carbs to live; a carnivore diet is viable”
But what does the science say?
Carbs are a critical source of energy, and safer than fats: True or False?
True and False, respectively! That is: they are a critical source of energy, and carbs and fats both have an important place in our diet.
❝Diets that focus too heavily on a single macronutrient, whether extreme protein, carbohydrate, or fat intake, may adversely impact health.❞

(the aforementioned lead author Dr. de Souza, by the way, served as an external advisor to the World Health Organization’s Nutrition Guidelines Advisory Committee)
Some carbs are beneficial; others are detrimental: True or False?
True! Glycemic index is important here. There’s a big difference between eating a raw carrot and drinking high-fructose corn syrup:
Which Sugars Are Healthier, And Which Are Just The Same?
While some say grains and/or starchy vegetables are bad, best current science recommends:
- Eat some whole grains regularly, but they should not be the main bulk of your meal (non-wheat grains are generally better)
- Starchy vegetables are not a critical food group, but in moderation they are fine.
To this end, the Mediterranean Diet is the current gold standard of healthful eating, per general scientific consensus:
A low-carb diet is best for overall health (and a carb is a carb): True or False?
True-ish and False, respectively. We covered the “a carb is a carb” falsehood earlier, so we’ll look at “a low-carb diet is best”.
Simply put: it can be. One of the biggest problems facing the low-carb diet though is that adherence tends to be poor—that is to say, people crave their carby comfort foods and eat more carbs again. As for the efficacy of a low-carb diet in the context of goals such as weight loss and glycemic control, the evidence is mixed:
❝There is probably little to no difference in weight reduction and changes in cardiovascular risk factors up to two years’ follow-up, when overweight and obese participants without and with T2DM are randomised to either low-carbohydrate or balanced-carbohydrate weight-reducing diets❞
Source: Low-carbohydrate versus balanced-carbohydrate diets for reducing weight and cardiovascular risk
❝On the basis of moderate to low certainty evidence, patients adhering to an LCD for six months may experience remission of diabetes without adverse consequences.
Limitations include continued debate around what constitutes remission of diabetes, as well as the efficacy, safety, and dietary satisfaction of longer term LCDs❞
~ Dr. Joshua Goldenberg et al.

❝There should be no “one-size-fits-all” eating pattern for different patient´s profiles with diabetes.
It is clinically complex to suggest an ideal percentage of calories from carbohydrates, protein and lipids recommended for all patients with diabetes.❞

We do not need carbs to live; a carnivore diet is viable: True or False?
False. For a simple explanation:
The Carnivore Diet: Can You Have Too Much Meat?
There isn’t a lot of science studying the effects of consuming no plant products, largely because such a study, if anything other than observational population studies, would be unethical. Observational population studies, meanwhile, are not practical because there are so few people who try this, and those who do, do not persist after their first few hospitalizations.
Putting aside the “Carnivore Diet” as a dangerous unscientific fad, if you are inclined to meat-eating, there is some merit to the Paleo Diet, at least for short-term weight loss even if not necessarily long-term health:
What’s The Real Deal With The Paleo Diet?
For longer-term health, we refer you back up to the aforementioned Mediterranean Diet.

Stop Cancer 20 Years Ago
Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.
Get Abreast And Keep Abreast
This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.
What does she want us to know?
Start now
If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.
What this means for those of us without breast cancer (or a history therof) is: start now
Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.
Start what, you ask? Taking away its roots. And how?
Inflammation as the root of cancer
To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.
Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:
“and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”
So, fight inflammation now, and have a reduced risk of a lot of other woes later.
See: How to Prevent (or Reduce) Inflammation
Don’t settle for “normal”
People are told, correctly but not always helpfully, such things as:
- It’s normal to have less energy at your age
- It’s normal to have a weaker immune system at your age
- It’s normal to be at a higher risk of diabetes, heart disease, etc
…and many more. And these things are true! But that doesn’t mean we have to settle for them.
We can be all the way over on the healthy end of the distribution curve. We can do that!
(so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)
If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.
So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:
See: Focusing On Health In Our Sixties
Fast to live
Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.
This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.
See: Intermittent Fasting: We Sort The Science From The Hype
While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.
It’s never too late
All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”
The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.
Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.
Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:
- Knowing stuff
- Doing stuff
So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
