Health Benefits of Resistance Training vs Aerobic Exercise + Media Quote

I answered a media query on the benefits of cardiovascular exercise vs weight lifting for Medical Daily.  To expand upon it, here’s my take:

Weightlifting builds bone density in the bones of the muscles worked.  Squats can help build hip bone density, but not wrist bone density, which would require stress on the wrist from an exercise such as a chest press or forearm exercise.
 
Weight lifting is effective for increasing glucose sensitivity (blood sugar sensitivity).  This means that some people, such as a person who is diabetic, may not need as much insulin as usual or that the person can consume more carbohydrate without negative effects on their body.
 
Resistance training also builds physical strength, improves muscle coordination, and is a stimulus to the body to increase lean mass.  Because of increases in lean mass, weight lifting is effective in improving body composition (lowering fat mass % and increasing lean mass %), which can improve self esteem and body confidence.  Being stronger can make daily tasks easier, makes you more athletic, and allows you to push your body more intensely during other exercises.
 
Cardio in the light to moderate intensity range stimulates the body to increase overall blood volume, thereby increasing the amount of red blood cells if the behavior is maintained for over a month (the time it takes to remake blood cells).

This happens because cardio can stimulate an increase in overall blood plasma volume, the watery component of blood.  With more blood volume, the density of the red blood cells in the blood is diluted.  The kidneys recognize this and secrete erythropoetin, a hormone that acts on the bone marrow to produce more blood cells to match the new blood volume.
 
Cardio is helpful for reducing blood pressure acutely.  This could be due to relaxation of the blood vessels due to exertion, a loss of fluid and sodium from the body, an increase in nitric oxide production (dilates blood vessels), or a combination of these.  Cardio in the light to moderate intensity range also creates adaptations in the peripheral cardiovascular system, such as increasing capillary density and overall efficient circulation.
 
All cardio will increase the blood circulation by utilizing the muscles of the body to pump blood that is in the veins back to the heart.  This is called the muscle pump, and it only works when you are moving.  This reduces the work the heart must do to pump fresh blood throughout the body.  It also increases the stroke volume of the heart–the amount of blood pumped per heart beat.  This can result in lower heart rates due to greater heart efficiency.
 
Most people can expend the largest amount of energy (calories) with light to moderate cardiovascular exercise when performed to exhaustion compared with weightlifting or intense cardio when performed to exhaustion, which is important when balancing dietary intake of calories.

 

Light to moderate cardio also does not spike caloric needs for repair as much as weight lifting or intense cardio due to less muscle breakdown, which is helpful for not slowing down the weight loss process (due to increases in lean mass, some people consider the “afterburn”).
 
To clarify, often people think that more exercise is better for weight loss.  This is not true.  If your body is broken down, caloric needs increase.  If needs are increased while you are not consuming enough for repair, your body won’t lose weight.

 

Instead, it will stall until it is healed.  It’s like, why would it lose weight if you are telling it to gain lean mass.  Lean mass gains and weight loss at the same time can be conflicting goals that will take twice as long to achieve either goal.  It is important to focus one’s goals.
 
Think about it.  How many people actually lose weight from a marathon?  Some people gain weight from it.  How does that make sense other than the explanation above?  Back to cardio…
 
Intense cardio can improve VO2max, the maximum amount of oxygen a person can consume and a measure of cardiovascular fitness.  Intense cardio improves cardiovascular fitness the best.  It burns the most calories per unit of time so is great for maximizing your workout time, if time is limited; however most people fatigue (beginners or athletes) before it would burn an equivalent amount of calories of moderate cardio to exhaustion or even sub-exhaustion.
 
For me, I know I can burn 600-700 Calories on a treadmill on an incline at a moderate pace in 35-40 min.  If I push myself and do intense cardio (mile time speed or sprint intervals), I burn out in 15-20 minutes and have only burned 200-400 Calories.  Yes, there is an afterburn, but I think that is overhyped.  We don’t talk about the afterburn from weight lifting–we call it soreness or delayed onset muscle soreness (DOMS).
 
Intense cardio should be performed for the aerobic fitness stimulus and not viewed soley as a caloric energy dump.  Successful weight loss clients use exercise to build skills and use larger volumes (sets, reps, time) of exercise to keep it off after the weight loss process is over but not during the process.

 

Why would you commit to 6 days of exercise for the purpose of weight loss in an unsustainable manner?  Are you planning to exercise for 6 days a week for the rest of your life?  It’s just asking for an injury.  People who request this are often given it by trainers because it can be lucrative, or they don’t know any better themselves.

 

Listening to a real exercise professional will save you some money and hard work.  I do not support these sorts of weight loss endeavors.  Diets are there for a reason.  It’s all about the dietary caloric deficit.  Check out the cool graph on this post, in case you missed it!  You’d be surprised how little I exercise to maintain a great physique.  Nutrition is very important, and focused, purposeful, goal-oriented exercise also is very important.

 

Intense cardio also improves central cardiovascular functions (heart, and forced inspiration and expiration muscles) more than moderate cardio, but it is often more physically and psychologically stressful.  For this reason, I recommend doing it only when you are rested and recovered (from a leg and cardiovascular workout history standpoint).  Cardio will also improve blood sugar sensitivity of muscle at any intensity just as weight lifting will.

My Fit Foods & SNAP Kitchen vs RD Private Services

Remember the story of the three little pigs?  One built his house of straw, one built his house of sticks, and the other built his house of bricks.  The big bad wolf came and blew everyone’s down except for the one who built his house of bricks.  The same can hold true with making nutrition choices and taking the easy way out.

My Fit Foods and SNAP Kitchen would fit in this story as the house of straw or house of sticks.  You can get a calorie-controlled, healthy proportioned set of meals through them.  The more food you buy, the more you pay.  Because larger people get more food than smaller people to maintain their weight, larger and taller people will pay more money at these places.

This is great for people who don’t have time to assemble meals themselves and are concerned with a weight goal or meeting a certain calorie level for exercise and sports.  They take the knowledge needed to assemble healthy meals that meet your needs out of the equation so that you can just be dependent on them for the rest of your life.

This is not much different than meal replacement systems like Nutrisystem, Herbalife, and Medifast.  It’s just food and not liquid supplements or powders.

I have seen the food bills for My Fit Foods and SNAP Kitchen.  For anywhere between $550 to $700 for three weeks, you can get meals (you could make yourself) already made for you in pre-portioned quantities to meet your goals.  If you don’t cheat, you’ll reach your goals.  This comes down to $183 to $233 per week in food for 1200-1800 Calories.

Guess how much I spend on food a week at the grocery store?  Anywhere from $30 to $70, depending on how much food I’m out of.  I also eat anywhere between 2700-3300 Calories per day as someone who is active most days of the week.  When I lost my weight, it was even less, usually closer to the $30 mark.

I’ve even lived on $20 for 5 days worth of meals when I had to do the food stamp challenge, and I still was consuming 2900 nutritious Calories per day.  Eating healthy is NOT expensive.  I do not know where this myth comes from.

Cooking your own meals, you’d save $150 per week, $600 per month, or about $7500 per year if you don’t rely on My Fit Foods, SNAP Kitchen, or other meal system for all your meals.  You could even go out to eat once or twice a week and STILL have plenty of money left over.

Many Millennials (born 1980s to early 2000s) eat out ALL the time.  They do not know how to cook or what they should include in meals for proper nutrition.  It doesn’t have to be gluten-free, organic, or non-GMO for it to be healthy either.

What happens when you quit any of these pre-made meal systems?  You could gain the weight back!  Most people probably don’t exercise considerably enough to eat whatever they want.  Meanwhile, you are lost for making food choices on your own or how to prepare food.  The principles and habits of weight management and fitness were not instilled for lasting change.

Now let’s compare these meal replacement systems to the cost of a typical visit with a registered dietitian.  Most RDs (or RDNs, same credential) charge anywhere from $75 to $200 or more per visit, depending on area they are located, education and experience, specialty, and the demographic they tend to work with.  This is about the same as what a psychotherapist charges or a massage therapist charges.

I list my prices on my website because I figure if you have to ask what the price is, it won’t be standard for everyone and probably assumed to be too expensive.

With an RD visit, you learn what you are doing with food and nutrition.  You gain confidence in your ability to prepare foods that meet your needs and wants.  It gives you the FREEDOM to eat the foods you want while still achieving the body type you want while paying SIGNIFICANTLY LESS than meal replacement systems.  You also invest in your own knowledge and get personalized information relative to your particular lifestyle and health history.

Chances are, you won’t have to meet with the RD weekly for a full year to get on track.  Most clients can get on track within a few sessions (1-5), depending on any barriers they must get past.  From a financial standpoint, making the time to consult with a professional is a HUGE return on investment (ROI).

With a visit to a registered dietitian, you are learning how to fish–not being given a fish dinner.  You are building a house of bricks.  It will take some initial time and effort, but once you get it, you’re good for life.  No one is going to blow your house down when you know how to build and repair a quality house of bricks.
