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)

And yes, that last one is also something that some people want/need to do (healthily!), and want/need help with that.

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 the first part: 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:

BMI and all-cause mortality in older adults: a meta-analysis

Body weight, muscle mass, and protein:

That BMI of 27, or whatever weight you might wish to be, ignores body composition. You’re probably aware that volume-for-volume, muscle weighs more than fat.

You’re also probably aware that if we’re not careful, we tend to lose muscle as we get older. This is known as age-related sarcopenia:

Protein, & Fighting Sarcopenia

Dr. Gabrielle Lyon, our featured expert in the above article, recommends getting at least 1.6g of protein per kg of body weight per day (Americans, divide your weight in pounds by 2.2 to get your weight in kg).

So for example, if you weigh 165lb, that’s 75kg, that’s 1.6×75=120g of protein per day.

There is an upper limit to how much protein per day is healthy, and that limit is probably around 2g of protein per kg of body weight per day:

Protein: How Much Do We Need, Really?

You may be wondering: should we go for animal or plant protein? In which case, the short version is:

• If you only care about muscle growth, any complete sources of protein are fine
• If you care about your general health too, then avoiding red meat is best, but other common protein sources are all fine
• Unprocessed is (unsurprisingly) better than processed in either case

What exercises are best for muscle-building?

Of course, different muscles require different exercises, but for all of them, resistance training is what builds muscle the most, and it’s pretty much impossible to build a lot of muscle otherwise.

Check out: Resistance Is Useful! (Especially As We Get Older)

Prepare to fail!

No, really, prepare to fail. Because while resistance training in general is good for maintaining strong muscles and bones, you will only gain muscle if your current muscle is not enough to do the exercise:

• If you do a heavy resistance exercise without undue difficulty, your muscles will say to each other “Good job, team! That was hard, but luckily we were strong enough; no changes necessary”.
• If you do a heavy resistance exercise to the point where you can no longer do it (called: training to failure), then your muscles will say to each other “Oof, what a task! What we’ve got here is clearly not enough, so we’ll have to add more muscle for next time”.

Safety note: training to failure comes with safety risks. If using free weights or weight machines, please do so under well-trained supervision. If doing it with bodyweight (e.g. press-ups until you can press no more) or resistance bands, please check with your doctor first to ensure this is safe for you.

You can also increase the effectiveness of your resistance training by doing it in a way that “confuses” your muscles, making it harder for them to adapt in the moment, and thus forcing them to adapt more in the long term (e.g. get bigger and stronger):

HIIT, But Make It HIRT: High Intensity Resistance Training

Make time for recovery

While many kinds of exercise can be done daily, exercise to build muscle(s) means at the very least resting that muscle (or muscle group) the next day.

For this reason, a lot of bodybuilders have for example a week’s schedule that might look like:

• Monday: Upper body training
• Wednesday: Lower body training
• Friday: Core strength training

…and rest on other days. This gives most muscles a full week of recovery, and every muscle at least 48 hours of recovery.

Note: bodybuilders, like children (who are also doing a lot of body-building, in their own way) need more sleep in order to allow for this recovery and growth to occur. Serious bodybuilders often aim for 12 hours sleep per day. This might be impractical, undesirable, or even impossible for some people, but it’s a factor to be borne in mind and not forgotten.

Anything else that can (safely and healthily) be done to promote muscle growth?

There are a lot of supplements on the market; some are healthy and helpful, other not so much. Here are some we’ve written about:

Take care!

As individuals, we can’t do much about the outside air. We can try to spend more time in green spaces* and away from traffic, and we can wear face-masks—as was popular in Tokyo and other such large cities long before the pandemic struck.

*The well-known mental health benefits aside (and contrary to British politician Amber Rudd’s famous assertion in a televised political debate that “clean air doesn’t grow on trees”), clean air comes mostly from trees—their natural process of respiration scrubs not only carbon dioxide, but also pollutants, from the air before releasing oxygen without the pollutants. Neat!

We are fortunate to be living in a world where most of us in industrialized countries can exercise a great degree of control over our home’s climate. But, what to do with all that power?

Temperature

Let’s start with the basics. Outside temperature may vary, but you probably have heating and air conditioning. There’s a simple answer here; the optimal temperature for human comfort and wellbeing is 20℃ / 68℉:

Scientists Identify a Universal Optimal Temperature For Life on Earth

Note: this does not mean that that is the ideal global average temperature, because that would mean the polar caps are completely gone, the methane stored there released, many large cities underwater, currently hot places will be too hot for human life (e.g. outside temperatures above human body temperature), there will be mass extinctions of many kinds of animals and plants, including those we humans require for survival, and a great proliferation of many bugs that will kill us. Basically we need diversity for the planet to survive, arctic through to tropical and yes, even deserts (deserts are important carbon sinks!). The ideal global average temperature is about 14℃ (we currently have about 15℃ and rising).

But, for setting the thermostat in your home, 20℃ / 68℉ is perfect for most people, though down as far as 17℃ / 61℉ is fine too, provided other things such as humidity are in order. In fact, for sleeping, 18℃ / 62℉ is ideal. This is because the cooler temperature is one of the several things that tell our brain it is nighttime now, and thus trigger secretion of melatonin.

If you’re wondering about temperatures and respiratory viruses, by the way, check out:

The Cold Truth About Respiratory Infections: The Pathogens That Came In From The Cold

Humidity

Most people pay more attention to the temperature in their home than the humidity, and the latter is just as important:

❝Conditions that fall outside of the optimal range of 40–60% can have significant impacts on health, including facilitating infectious transmission and exacerbating respiratory diseases.

When humidity is too low, it can cause dryness and irritation of the respiratory tract and skin, making individuals more susceptible to infections.

When humidity is too high, it can create a damp environment that encourages the growth of harmful microorganisms like mould, bacteria, and viruses.❞

~ Dr. Gabriella Guarnieri et al.

So, if your average indoor humidity falls outside of that range, consider getting a humidifier or dehumidifier, to correct it. Example items on Amazon, for your convenience:

Now, one last component to deal with, for perfect indoor air:

Pollution

We tend to think of pollution as an outdoors thing, and indeed, the pollution in your home will (hopefully!) be lower than that of a busy traffic intersection. However…

• The air you have inside comes from outside, and that matters if you’re in an urban area
• Even in suburban and rural areas, general atmospheric pollutants will reach you, and if you’ve ever been subject to wildfire smoke, you’ll know that’s no fun either.
• Gas appliances in the home cause indoor pollution, even when carbon monoxide is within levels considered acceptable. This polluting effect is much stronger for open gas flames (such as on gas cookers/stoves, or gas fires), than for closed gas heating systems (such as a gas-powered boiler for central heating).
• Wood stoves/fireplaces are not an improvement, in fact they are worse, and don’t get us started on coal. You should not be breathing these things, and definitely should not be burning them in an enclosed space.
• That air conditioning, humidifier, dehumidifier? They may be great for temperature and humidity, but please clean/change the filter more often than you think is necessary, or things will grow there and then your device will be adding pathogens to the air as it goes.
• Plug-in air-freshening devices? They may smell clean, but they are effectively spraying cleaning fluids into your lungs. So please don’t.

So, what of air purifiers? They can definitely be of benefit. for example:

Air Purifiers & Sleep

But watch out! Because if you don’t clean/change the filter regularly, guess what happens! That’s right, it’ll be colonized with bacteria/fungus and then be blowing those at you.

And no, not all of them will be visible to the naked eye:
