What Do You Have To Gain?

We have previously promised a three-part series about changing one’s weight:

  1. Losing weight (specifically, losing fat)
  2. Gaining weight (specifically, gaining muscle)
  3. Gaining weight (specifically, gaining fat)

There will be, however, no need for a “losing muscle” article, because (even though sometimes a person might have some reason to want to do this), it’s really just a case of “those things we said for gaining muscle? Don’t do those and the muscle will atrophy naturally”.

Here’s our first article: How To Lose Weight (Healthily!)

While some people will want to lose fat, please do be aware that the association between weight loss and good health is not nearly so strong as the weight loss industry would have you believe:

Shedding Some Obesity Myths

And, while BMI is not a useful measure of health in general, it’s worth noting that over the age of 65, a BMI of 27 (which is in the high end of “overweight”, without being obese) is associated with the lowest all-cause mortality:

Here was our second article: How To Build Muscle (Healthily!)

And now, it’s time for the last part, which yes, is also something that some people want/need to do (healthily!), and want/need help with that.

How to gain fat, healthily

Fat gets a bad press, but when it comes to health, we would die without it.

Even in the case of having excess fat, the fat itself is not generally the problem, so much as comorbid metabolic issues that are often caused by the same things as the excess fat.

So, how to gain fat healthily?

  • Obvious but potentially dangerously misleading answer: “in moderation”
  • More useful answer: “carefully”

Because, you can “in moderation” put on less than one pound per week for a few years and be in very bad health by the end of it. So how does this “carefully” work any differently to “in moderation”?

The key is in how we store the fat

Not merely where we store it (though that’ll follow from the “how”), but specifically: how we store it.

  • When we consume energy from food in excess of our immediate survival needs, our body stores what it can. This is good!
  • When our body is receiving energy from food faster than it can physically process it to store it healthily, it will start shoving it wherever it can instead. This is bad!

This is the physiological equivalent of the difference between tidying a room carefully, and cramming everything into one cupboard in 30 seconds just to get it out of sight.

So, you do need to consume calories yes, but you need to consume them in a way your body can take its time about storing them.

We’ve written before about the science of this, so we’ll share some links to that in a moment, but first, here are the practical tips:

  • Do not drink your calories. Drinking calories tends to be the equivalent of injecting sugars directly into your veins, in terms of how quickly it gets received.
    • See also: How To Unfatty A Fatty Liver ← this is highly relevant, because the same process that results in unhealthy weight gain, results in liver disease, by the same mechanism (the liver gets overwhelmed).
  • Eat your greens. No, they won’t provide many calories, but they are critical to your body not being overwhelmed by the arrival of sugars.
    • See also: 10 Ways To Balance Blood Sugars ← the other 9 things are also helpful for not putting on fat unhealthily, so using these alongside a calorie-dense diet can result in healthy fat gain as needed
  • Get more of your calories from fats than carbs. Fats will not overwhelm your body’s glycemic response in the same way that carbs will.
  • Consider going low-carb, but even if you choose not to, go for carbs with a low glycemic index instead of a high glycemic index.
  • Need healthy fats in a snack? Enjoy nuts (unless you have an allergy); they will be your best friend in this regard. As an example, a mere 1oz portion of cashew nuts has 157 calories.
  • Need health fats for cooking? Enjoy olive oil, as it has one of the healthiest lipids profiles available, and is a great way to increase the calorific content of many meals.

Lastly…

Be patient, enjoy your food, and stick as best you can to the above considerations. All strength to you.

Take care!

  • 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:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
