Metabolic Health Roadmap – by Brenda Wollenberg

The term “roadmap” is often used in informative books, but in this case, Wollenberg (a nutritionist with decades of experience) really does deliver what can very reasonably be described as a roadmap:
She provides chapters in the form of legs of a journey [to better metabolic health], and those legs are broadly divided into an “information center” to deliver new information, a “rest stop” for reflection, “roadwork” to guide the reader through implementing the information we just learned, in a practical fashion, and finally “traveller assistance” to give additional support / resources, as well as any potential troubleshooting, etc.
The information and guidance within are all based on very good science; a lot is what you will have read already about blood sugar management (generally the lynchpin of metabolic health in general), but there’s also a lot about leveraging epigenetics for our benefit, rather than being sabotaged by such.
There’s a little guidance that falls outside of nutrition (sleep, exercise, etc), but for the most part, Wollenberg stays within her own field of expertise, nutrition.
The style is idiosyncratic; it’s very clear that her goal is providing the promised roadmap, and not living up to any editor’s wish or publisher’s hope of living up to industry standard norms of book formatting. However, this pays off, because her delivery is clear and helpful while remaining personable and yet still bringing just as much actual science, and this makes for a very pleasant and informative read.
Bottom line: if you’d like to improve your metabolic health, as well as get held-by-the-hand through your health-improvement journey by a charming guide, this is very much the book for you!

Nicotine Benefits (That We Don’t Recommend)!
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Does nicotine have any benefits at all? I know it’s incredibly addictive but if you exclude the addiction, does it do anything?❞
Good news: yes, nicotine is a stimulant and can be considered a performance enhancer, for example:
❝Compared with the placebo group, the nicotine group exhibited enhanced motor reaction times, grooved pegboard test (GPT) results on cognitive function, and baseball-hitting performance, and small effect sizes were noted (d = 0.47, 0.46 and 0.41, respectively).❞

However, another study found that its use as a cognitive enhancer was only of benefit when there was already a cognitive impairment:
❝Studies of the effects of nicotinic systems and/or nicotinic receptor stimulation in pathological disease states such as Alzheimer’s disease, Parkinson’s disease, attention deficit/hyperactivity disorder and schizophrenia show the potential for therapeutic utility of nicotinic drugs.
In contrast to studies in pathological states, studies of nicotine in normal-non-smokers tend to show deleterious effects.
This contradiction can be resolved by consideration of cognitive and biological baseline dependency differences between study populations in terms of the relationship of optimal cognitive performance to nicotinic receptor activity.
Although normal individuals are unlikely to show cognitive benefits after nicotinic stimulation except under extreme task conditions, individuals with a variety of disease states can benefit from nicotinic drugs❞
Read in full: Effects of nicotinic stimulation on cognitive performance
Bad news: its addictive qualities wipe out those benefits due to tolerance and thus normalization in short order. So you may get those benefits briefly, but then you’re addicted and also lose the benefits, as well as also ruining your health—making it a lose/lose/lose situation quite quickly.
As an aside, while nicotine is poisonous per se, in the quantities taken by most users, the nicotine itself is not usually what kills. It’s mostly the other stuff that comes with it (smoking is by far and away the worst of all; vaping is relatively less bad, but that’s not a strong statement in this case) that causes problems.

However, this is still not an argument for, say, getting nicotine gum and thinking “no harmful effects” because then you’ll be get a brief performance boost yes before it runs out and being addicted to it and now being in a position whereby if you stop, your performance will be lower than before you started (since you now got used to it, and it became your new normal), before eventually recovering:
In summary
We recommend against using nicotine in the first place, and for those who are addicted, we recommend quitting immediately if not contraindicated (check with your doctor if unsure; there are some situations where it is inadvisable to take away something your body is dependent on, until you correct some other thing first).

Cherries vs Blackberries – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing cherries to blackberries, we picked the blackberries.
Why?
In terms of macros, cherries have more carbs while blackberries have more protein and fiber. The protein of course is a tiny amount and an even tinier difference, and/but it’s worth noting that the fiber isn’t, and blackberries have more than 3x the fiber. So, a win for blackberries in this category.
In the category of vitamins, cherries have more of vitamins A, B1, B2, and B6, while blackberries have more of vitamins B3, B5, B9, C, E, K, and choline. Another win for blackberries.
When it comes to minerals, cherries have a tiny bit more potassium, while blackberries have considerably more calcium, copper, iron, magnesium, manganese, phosphorus, selenium, and zinc. Another easy win for blackberries.
Both fruits have abundant antioxidants, but as many are different, and comparison between them becomes more subjective than we have room for here.
In short, enjoy either or both, but we say blackberries win overall on macro- and micronutrients!

What Different Kinds of Hair Loss/Thinning Say About Your Health
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dr. Siobhan Deshauer shows us different kinds of hair loss, what causes them, and what can be done about them:
Many different causes
Here’s how to tell them apart:
- Alopecia areata is an autoimmune condition where the immune system mistakenly attacks hair follicles, causing hair loss that can occur at any age and affects about 1 in 50 people. It often presents as smooth patches of hair loss and can be treated with steroid injections. Severe cases may require high-dose prednisone, which can restore hair growth over time.
- Discoid lupus is an autoimmune disease that affects the skin, leading to inflammation, scarring, and permanent hair loss. Unlike alopecia areata, it causes visible damage to the scalp and hair follicles. This type of lupus typically does not involve internal organs, unlike systemic lupus.
- Telogen effluvium occurs when a major systemic shock, such as an infection, surgery, or significant stress, triggers many hair follicles to enter the resting phase simultaneously, resulting in delayed hair shedding. The condition is diagnosed with a “hair pull test” and is typically temporary, as the resting phase is followed by normal hair growth phases.
- Allergic reactions to products, such as hair dye containing PPD, can cause hair loss due to scalp irritation and inflammation. An allergic response may trigger hair follicles to enter a resting phase, leading to hair loss by the same mechanism as telogen effluvium. Treatment with steroids can calm the reaction, and hair usually regrows after recovery.
- Syphilis, a sexually transmitted infection, can present with varied symptoms, including hair loss in a distinct moth-eaten pattern. Hair loss due to syphilis is reversible and curable with penicillin treatment, with hair regrowth typically occurring a few months after treatment.
- Biotin deficiency is rare due to its production by gut bacteria and presence in foods such as nuts, seeds, and beans such as soybeans. Deficiency can result from excessive consumption of raw egg whites, which block absorption. Severe deficiency causes hair loss and skin issues but can be treated effectively with biotin supplements.
- Iron deficiency anemia can cause hair thinning along with symptoms like fatigue and breathlessness. It often results from inadequate dietary intake, but can also occur after heavy menstrual bleeding. Treatment with iron supplements, or blood transfusions in severe cases, can restore both hair and energy levels, leading to significant improvements.
- Trichotillomania is a psychological condition marked by an uncontrollable urge to pull out one’s hair, often associated with anxiety or depression. Hair patches may show different stages of regrowth. While it can be challenging to manage, the condition can be treated with appropriate psychological and medical support.
- Traction alopecia results from hairstyles that exert prolonged tension on the hair, causing it to thin or fall out. This type of hair loss can be prevented by reducing the strain on the hair. Loosening hairstyles and giving the scalp a break can help hair regrow over time.
- Hypothyroidism causes symptoms like fatigue, dry skin, and hair thinning due to insufficient thyroid hormone production—however, it can be managed with diet, and if necessary, thyroid medications.
- Zinc deficiency may also cause hair loss and a characteristic rash. Treatment with zinc supplements can significantly improve hair growth and other symptoms.
- Medications, such as chemotherapy drugs, Accutane, and anti-seizure medications like valproic acid, are known to cause hair loss as a side effect. This type of hair loss is often reversible once the medication is stopped.
- Male pattern hair loss, or androgenic alopecia, is influenced by testosterone and genetic risk factors—which, contrary to popular belief, can come from either or both sides of the family. Early onset, especially before age 40, is linked to an increased risk of heart disease. However, effective treatments are available, and early intervention is beneficial.
- Female pattern hair loss is basically the same thing as male pattern hair loss (indeed, it is literally still androgenic alopecia), just a) almost always much less severe and b) with a gender-appropriate name. It affects up to 40% of women by age 50 and is characterized by thinning hair at the top of the head. It’s related to hormonal imbalances involving testosterone, such as those seen in PCOS and menopause, amongst other less common causes. Early treatment can be effective, and research is ongoing to develop more targeted therapies.
Dr. Siobhan Deshauer advises, if you’re experiencing hair loss, to monitor other symptoms too if applicable, take photos for tracking, and consult a doctor early for diagnosis and potential treatment.

What Loneliness Does To Your Brain And Body
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Spoiler: it’s nothing good (but it can be addressed!)
Not something to be ignored
Loneliness raises the risk of heart disease by 29% and the risk of stroke by 32%. It also brings about higher susceptibility to illness (flu, COVID, chronic pain, etc), as well as poor sleep quality and cognitive decline, possibly leading to dementia. Not only that, but it also promotes inflammation, and premature death (comparable to smoking).
This is because the lack of meaningful social connections activates the body’s stress response, which in turn increases paranoia, suspicion, and social withdrawal—which makes it harder to seek the social interaction needed to alleviate it.
On a neurological level, cortisol levels become imbalanced, and a faltering dopamine response leads to impulsive behaviors (e.g., drinking, gambling) to try to make up for it. Decreased serotonin, oxytocin, and natural opioids reduce feelings of happiness and negate pain relief.
As for combatting it, the first-line remedy is the obvious one: connecting with others improves emotional and physical wellbeing. However, it is recommended to aim for deep, meaningful connections that make you happy rather than just socializing for its own sake. It’s perfectly possible to be lonely in a crowd, after all.
A second-line remedy is to simply mitigate the harm by means of such things as art therapy and time in nature—they can’t completely replace human connection, but they can at least improve the neurophysiological situation (which in turn, might be enough of a stop-gap solution to enable a return to human connection).

Greek Yogurt vs Cottage Cheese – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing Greek yogurt to cottage cheese, we picked the yogurt.
Why?
These are both dairy products popularly considered healthy, mostly for their high-protein, low-carb, low-fat profile. We’re going to assume that both were made without added sugars. Thus, their macro profiles are close to identical, and nothing between them there.
In the category of vitamins, both are a good source of some B vitamins, and neither are good source of much else. The B-vitamins they have most of, B2 and B12, Greek yogurt has more.
We’ll call this a small win for Greek yogurt.
As they are dairy products, you might have expected them to contain vitamin D—however (unless they have been artificially fortified, as is usually done with plant-based equivalents) they contain none or trace amounts only.
When it comes to minerals, both are reasonable sources of calcium, selenium, and phosphorus. Of these, they’re equal on the selenium, while cottage cheese has more phosphorus and Greek yogurt has more calcium.
Since it’s also a mineral (even if it’s usually one we’re more likely to be trying to get less of), it’s also worth noting here that cottage cheese is quite high in sodium, while Greek yogurt is not.
Another win for Greek yogurt.
Beyond those things, we’d be remiss not to mention that Greek yogurt contains plenty of probiotic bacteria, while cottage cheese does not.

Increase Your Muscle Mass Boost By 26% (No Extra Effort, No Supplements)
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
You’ve probably seen this technology advertised, but the trick is in how it’s used (which is not how most people use it).
It’s about neuromuscular electrical stimulation (NMES), also called electrical muscle stimulation (EMS); in other words, those squid-like electrode kits that promise “six-pack abs without exercise”, by stimulating the muscles for you—using the exact same tech as for transcutaneous electrical nerve stimulation (TENS), for pain relief.
Do they work for pain relief? Yes, for many people in any case. But that’s beyond the scope of today’s article.
Do they work for building muscles as advertised? No. The limiting factor is that they can’t fully exert the muscles in the same way actual exercise can, because of the limitations to how much electrical current can safely be applied.
However…
The cyborgization of your regular workout
A meta-analysis of 13 studies compared two [meta-]groups of exercisers:
- Group 1 doing conventional resistance training
- Group 2 doing the same resistance training, plus NMES at the same time (specifically: NMES of the same muscles being used in the workout)
The analysis had two output variables: strength and muscle mass
What they found: group 2 enjoyed more than 31% greater strength gains, and 26% greater muscle mass gains, from the same training over the same period of time.
Of course, one of the biggest challenges to strength gain and muscle mass gain is hitting a plateau, so it’s worth noting that when they looked at training periods ranging from 2 weeks to 16 weeks, longer durations yielded better results—it is, it seems, the gift that keeps on giving.
You can find the paper here (which also explains how they analysed data from 13 different studies to get one coherent set of results):
How it works and why it matters
While the paper itself does not go into how it works, a reasonable hypothesis is that it works by “confusing” the muscles—because they are receiving mixed signals (one set from your brain, one set from the electrodes), with fast- and slow-twitch muscle fibers both working at the same time.
Another way to “confuse” the muscles is by High Intensity [Interval] Resistance Training (HIRT)—which is basically High Intensity Interval Training (HIIT), but for resistance training specifically.
See: How To Do HIIT (Without Wrecking Your Body) and HIIT, But Make It HIRT
Now, we want to confuse our muscles, not our readers, so if that’s all too much to juggle at once, just pick one and go with it. But today’s article is about the RT+NEMS combination, so perhaps you’ll pick that.
Why it matters: as we get older, sarcopenia (the loss of muscle mass) becomes more of an issue, and even if we’re not inclined to a career in bodybuilding, we do still need to at least maintain a healthy muscle mass because:
- Strong muscles improve our stability and make us less likely to fall
- Strong muscles force the body to build strong bones to hold them on, which means lower risk of fractures or worse
- Muscle mass itself improves the body’s basal metabolic rate, which means systemic benefits to the whole body (including against metabolic diseases especially)

Want to try it?
If you don’t already have a NMES/EMS/TENS kit lying around the house, here’s an example product on Amazon—remember to use it simultaneously with your regular resistance training workout, on the same muscles at the same time, to get the benefit we talked about! 😎
