Research Update: Can Exercise Counter the Negative Effects of Excess Weight?

You’ve probably already noticed in several news organizations the publication of research findings in the European Journal of Preventive Cardiology that assessed the claim that a high cardiorespiratory fitness (CRF) might mitigate the detrimental effects of excess body weight on cardiometabolic health, termed the ‘fat but fit’ paradox. Can CRF negate the negative effects of excess weight? Let’s find out…

We’re going to skip to the end of the story for you:

According to study author Dr. Alejandro Lucia of the European University, Madrid, Spain, “Exercise does not seem to compensate for the negative effects of excess weight. This finding was also observed overall in both men and women when they were analysed separately.”

…refute the notion that a physically active lifestyle can completely negate the deleterious effects of overweight/obesity…

Joint association of physical activity and body mass index with cardiovascular risk: a nationwide population-based cross-sectional study

Study highlights

The specific study notes, “…the present findings, which are based on data from insured active workers across Spain, represent one of the largest studies to date (n = 527 662) and refute the notion that a physically active lifestyle can completely negate the deleterious effects of overweight/obesity.”

Want more data, then try “…a study conducted in 2196 participants reported that although PA was associated with a lower CVD risk within each BMI category during a 30-year follow-up, individuals with overweight or obesity presented with an increased CVD risk regardless of their PA levels…”

Or let this one sink in, “… in line with our findings, a systematic review concluded that an excess BMI is associated with increased CVD risk irrespective of PA levels.” Put another way, physical activity (PA) levels for those with a high BMI, did not alleviate cardiovascular disease (CVD) risks.

We’re not selectively pulling from this study. It shows PA is a good thing for any BMI level, but the study does not find that PA negates BMI or excess weight affects on health or CVD risks.

How did we get here?

The key point to notice is the researchers wanted to use science to test the “fat but fit” claim that has grown in recent years. What has driven this claim in several areas of modern culture is the conflation between a healthy body image and a healthy body. One is emotional, the other physiological. Too many supposed health and lifestyle outlets have been amplifying the belief that all that matters is that you are happy with who you are, and any level of activity is sufficient for health. First, we’re going to stay away from that argument here – there’s too much to unpack. Second, this study shreds that from the physiological aspect.

Third, if you have weight to lose, you have weight to lose. It’s not criticism, it’s about health.

A performance-focused solution

Building your lifestyle program around performance is a solid method to combat the negative effects of excess weight. Below are three tips, each from our performance triad, on how you can tackle your BMI, if needed.

Nutrition: Get serious about what you eat. No really, get f*ing serious about what you eat. Do not go nuts, do not go to extremes. But performance management of your BMI means you own your results. Performance diets are not guesswork, either – you need to spend some time with a pencil and calculator. Knowing your daily caloric and macronutrient needs to reach and sustain your performance means taking the time to run the numbers. Want more nutrition advice, then check out our article on Performance Diet Tips.

Fitness: Solve your time issues by using short duration, micro-HIIT sessions. These have shown the potential to be more beneficial than traditional exercise routines that rely on steady-state. Sound new? Their not – a 2016 study showed that one minute of intense training within a 10 minute period yielded the same results as a 50-minute steady-state trained group over a 12-week period. See our full Fitness Tip on Micro-HIIT.

Rest: As much as you exercise, and feed your body, a notable portion of your ability to manage weight comes from your rest cycle. Check out a good overview at The Healthy on how sleep helps burn fat. For now, here are some quick tips to help ensure you get proper rest: stick to a regular time for bed, it will keep your body on a schedule, do not over-sleep on the weekends, or off days, as this too will impact your body’s ability to manage its rests cycles, be careful with naps; they are fine, but too many, too long, or at the wrong time, and you can mess up your body’s sleep cycle, and during the day, get as much exposure to light as possible; this not only helps the body develop vitamin D, but also helps tell it to be awake.

Achieving Your Target Weight – Doing the Math

Achieving your target weight goal should not be the difficult challenge so many encounter; however, so many seem to have a hard time keeping on a path to reach it…sound familiar?

Many people struggle to stay on track to hitting their weight goals, and the solution may be as simple as dusting off a calculator, doing some math, and keeping track.

First, we’re going to assume that you have all the other parts dialed in – workout routine is built to get your results and you are eating a macronutrient balanced diet. What we are going to work on here, for you, is the science of weight control for achieving your target weight.

Let’s start with losing weight

Dropping weight for most means lowering body fat composition. In numbers 3,500 calories is a pound of body fat. To lose a pound, per week, you need to create a deficit of 3,500 calories. You can get there through burning calories (exercise), diet (eat less), or both.

Easy – maybe. So why do so many start this path, see beginning results, and then nothing? Answer is easy (hint, but keep it a secret…it’s the math)

What is the math of weight management

Everyone has a basic daily caloric intake need – officially known as your Total Daily Energy Expenditure (TDEE). 

This is the amount of calories you need on a daily basis to maintain your body weight. There are two formulas (using the MIFFLIN ST. JEOR EQUATION):

Men: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) + 5
Women: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) – 161

Basic Activity Factor

1.2: If you are sedentary (little or no exercise) = BMR x 1.2
1.375: If you are lightly active (light exercise/sports 1-3 days/week) = BMR x 1.375
1.55: If you are moderately active (moderate exercise/sports 3-5 days/week) = BMR x 1.55
1.725: If you are very active (hard exercise/sports 6-7 days a week) = BMR x 1.725
1.9: If you are extra active (very hard exercise/sports & physical job or 2x training) = BMR x 1.9

TDEE Example

Let’s meet Alex. Alex weighs 108 kg, 180 cm tall, 36 years old, and does light sport 3 days a week. Following this:

((10 x 108) + (6.25 x 180) – (5 x 36) + 5) x 1.375 = 2791 calories

Per week, Alex needs 19,537 to maintain his weight of 108 kg.

Now to lose a pound (.45 kg), Alex needs to reduce his caloric intake to 16,037 per week. And so he does, and the weight starts coming off, until it doesn’t. What happened?

This is where you are now going to understand how to avoid this pitfall. As the weight comes down, the math changes.

Let’s assume Alex is now 103 kg:

((10 x 103) + (6.25 x 180) – (5 x 36) + 5) x 1.375 = 2723 calories, or, 19,061 calories per week.

If Alex still has his diet adjusted to 16,037 calories per week, his deficit is only 3,024. A lot, but not enough to get off a pound. And as his weight drops, this will continue to be an issue.

And this is the mistake so many make in trying to achieve their target weight – keeping up the simple math behind the numbers.

So how do you avoid this? Simple – we recommend that for every 5 kg of weight loss, you do the math – work out your new TDEE.

If you are not seeing great results, and think your program is not working – it likely is for the most part, but it needs updating.

If you want to put away the calculator, you can head here, for a free online TDEE tool.

But you want to gain weight

Adding high-quality protein to your diet is essential for building muscle. Based on current research, your should consume 0.8g of protein for each kg of body weight as part of your TDEE. Let’s be clear – 0.8g per kg, just to maintain weight.

Research suggests that to support muscle development, one should increase protein intake to 1.5-2.0g per kg of body weight. For example, in a 90 kg individual, that would equate to 135-180 grams of protein per day. We strongly recommend your protein intake come from natural food sources; seek guidance from a registered dietician if you want to assess the affects of supplementation on your specific body.

In the end

This is why fitness programs, the good ones, will cycle through different elements every 3-6 weeks (depending on the program). It is because your body adjusts to a diet and workout. The same effort and calories that worked when you started a routine are not the ones that are going to get you across the finish line. Achieving your target weight means taking the time to monitor your progress, and make adjustments.

7 Tips for Training with Problem Spots

Problem spots…the trick joint…old sports injury…

We know these by many names. They are parts of our bodies, that while not injured, pose challenges for those trying to workout and keep fit. These are not active injuries, rather part of the body that just do not work at 100% any more (likely from an earlier injury).

So how can we keep fit, and deal with these problem spots?

  1. It’s a problem for a reason. Something happened, and part of your body was forever affected. This is where we all need to work with our physician to ensure we understand the mechanics of the issue. Guessing at why something is an issue is not the same as taking effective training steps based on solid knowledge.
  2. Do not confuse a problem for an injury. Listen to your body on this – pain, swelling, immobility, etc are signs you have an injury. Maybe minor, maybe not. But you never train on an injury. You seek medical advice, rest, and recover. But you’ve had a bad knee for years – OK, but today your knee decided to upgrade its issues. Be smart, put aside the ego, and treat the injury.
  3. Warm up the area. Get the blood flowing in the the area through simple stretches, and low intensity resistance movements. Keep it simple and slow, until, and if, your problem area is ready to go. For example, you have a tricky shoulder and its chest day… Try doing 10 reps of just the bar, followed by 10 reps of 30% 1RM (One Rep Max) – this will warm up the shoulders, and put just enough tension to let you see if they are OK to add weight. Push-ups? Do them on your knees to decrease the weight. You get the idea.
  4. Apply progressive levels of exercise, vs large jumps. That problem area is going to benefit from steady, progressive adjustments in difficulty, speed, or resistance. Manage the increase in slow amounts. This will keep the area active and warmed up, but also not shock it with in increase that could result in injury. Remember, there is a reason that area is a problem.
  5. Know when to quit. Again, get the ego out of the workout. If you have a problem area, and it acts up – before or during a workout – call it a day with that area. We bet there are other parts of your body you can exercise. Or, change exercises. We want to stress, without control, ego can turn a sore joint into something worse.
  6. Apply proper rest. Have we mentioned those areas are problems for a reason? They will need more attention that other areas after the workout. Foam roller, muscle creams, ice, adequate time off, etc are all critical to ensuring that problem areas have time to recover and rest before your next session with them.
  7. Eat a healthy diet. Your body as a whole, not just the problem area, will benefit from the macronutrients, vitamins, and minerals a healthy diet provides. Keeping beneficial fuel in the tank is vital to helping problem areas rest, recover, and get ready for your next workout.

With these steps, you should be able to manage exercising with a problem area. But remember – one, never, never, exercise on an injury, and two, your best source of advice on this is going to come from a medical professional who can diagnose your specific issues.

Vitamin D Benefits: Science or Hype?

First, what is Vitamin D exactly?

Vitamin D is required for the regulation of the minerals, calcium, and phosphorus found in the body. And in addition to calcium, it is an important aspect of maintaining proper bone structure.

Natural sunlight exposure is the easiest and most reliable way for most people to get vitamin D. Normal exposure of the hands, face, arms, and legs to sunlight 2-3 times a week for 10-30 minutes is sufficient time to produce enough vitamin D. The necessary exposure time varies with age, skin type, season, time of day, and other factors. During periods of sunlight, vitamin D is stored in your body fat and then released when sunlight is gone.

Vitamin D’s ability to help build strong bones by increasing the body’s absorption of calcium and phosphorous is long known. However, recent years have seen it associated as a defense against cancer, heart disease, diabetes, mood swings, and depression. But current studies are now altering our understanding of this vitamin, and while not diminishing its importance to our body’s health, may be challenging some decades-old hype.

In 2014, in a study funded by the National Institutes of Health, researchers recruited and studied the vitamin D effects in over 25,000 healthy U.S. adults over 50 for an average of almost 5 1/2 years. The study concluded that vitamin D supplements did not lower the risk of cancer, stroke, or heart attack.

And in early 2019, researchers published an analysis of prior studies on the link between vitamin D supplements, cancer risk, and survival. The analysis found no link between supplementation and reduced cancer risk; however, studies suggested that taking vitamin D supplements may lower the risk of dying from cancer by 13%. The study did not determine if the potential vitamin D supplement effect actually caused the body’s own immune system to improve and fight cancer, or if the supplement was directly responsible. In contrast to these possible positive results, a recently published Vitamin D and Omega-3 Trial (VITAL) noted that in a large study of more than 25,000 participants that those taking a vitamin D supplement did not lower rates of heart attack, stroke, or cancer. However, among people who later developed cancer, those who took vitamin D supplements for at least two years had a 25% lower chance of dying from their cancer compared with those who received a placebo.

Possible Assistance in Weight Loss

There is limited evidence vitamin D levels may affect one’s ability to lose weight.

In a 2009 study in the British Journal of Nutrition, some participants taking daily calcium and vitamin D supplement were able to lose more weight than subjects taking a placebo supplement.

Possible Evidence that Vitamin D Supplementation Could Reduce Respiratory Inflammation Risks

An April 2020 article in the periodical Nutrients, suggests vitamin D can reduce risk of infections.

According to the article’s researchers, vitamin D supports mechanisms that can lower viral replication rates and reduce concentrations of pro-inflammatory cytokines that produce lung inflammation that typically leads to pneumonia, as well as boosting concentrations of anti-inflammatory cytokines. Again, there are mixed results on this too, as several observational studies and clinical trials did not observe any effect from vitamin D in reducing the risk of influenza.

Natural Sources of Vitamin D

Foods that provide vitamin D include:

  • Fatty fish, like tuna, mackerel, and salmon
  • Foods fortified with vitamin D, like some dairy products, orange juice, soy milk, and cereals
  • Beef liver
  • Cheese
  • Egg yolks

Vitamin D Supplements

While research is ongoing, there are benefits from taking vitamin D supplements to promote bone health; however, large amounts of vitamin D are not required to get the benefit.  Notably, a 2010 study published in JAMA showed that intake of very high doses of vitamin D in older women was associated with more falls and fractures.

But too much vitamin D (or any supplment) can create risks. Taking a supplement that contains too much vitamin D can be toxic in rare cases. It can lead to hypercalcemia, a condition in which too much calcium builds up in the blood, potentially forming deposits in the arteries or soft tissues. It may also predispose women to painful kidney stones.

Vitamin D2 and D3

The most important forms of Vitamin D for the human body are D3 and (to a lesser extent) D2. If you select to take vitamin D supplements, choose a quality supplement and eating some foods fortified with D3.
