Best Energy Drink

What is the Best Energy Drink?

Energy drinks have grown in popularity in the past few years.  Energy drink have lots of caffeine, sugar, and even vitamins, nutrients, and minerals to perk you up.  Some people drink energy drinks to get an afternoon lift to get through the day.  Some people drink energy drinks to get rolling for a night out.

What is the best energy drink?  People have different preferences for flavor, and energy drinks don't seem to make claims about tasting great anyway.  It seems that the most important features of energy drinks are:

• Caffeine Content
• Calories
• Cost

Today we'll consider these factors to select the best energy drink.  We'll check popular energy drinks including 5 Hour Energy, Rockstar, Monster, Red Bull, Amp, and NOS.

How Much Caffeine is in Energy Drinks?

Before energy drinks were popular, people would drink a Mountain Dew for the same effect.  Mountain Dew has 54mg of caffeine in a 12 oz can.  How much caffeine is in energy drinks?

Table: Energy Drink Caffeine Content

Energy Drink	Caffeine Content (mg)
5 Hour Energy	215
Rockstar Energy Shot	230
Monster Energy	90
Red Bull	85
Amp	70
NOS	225

The tables above show the caffeine content of popular energy drinks.  All of these energy drinks have a lot more caffeine than a can of Mountain Dew.  NOS, 5 Hour Energy, and Rockstar are loaded with caffeine with over 200mg per container.  Monster, Red Bull, and Amp have under 100mg of caffeine per container.  If I were drinking an energy drink at night, I would choose one with less caffeine in order to interfere less with sleeping.

RedBull Energy Drink is available in at least four sizes!

How Many Calories are in Energy Drinks?

Some energy drinks contain calories to provide energy, while others have almost no calories.  If you drink energy drinks a lot, calories are a concern.

Energy Drink	Calories
5 Hour Energy	4
Rockstar Energy Shot	10
Monster Energy	100
Red Bull	110
Amp	110
NOS	220

As you can see in the tables above, 5 Hour Energy and Rockstar Energy Shot have almost no calories.  The other drinks on the list have about the same amount of calories as a soda pop like Mountain Dew.

How Much Do Energy Drinks Cost?

You can buy a 16 oz bottle of Mountain Dew for about $1.50.  How does the cost of energy drinks compare to Mountain Dew?

Table: Energy Drink Cost Table

Energy Drink	Cost
5 Hour Energy	$2.00
Rockstar Energy Shot	$2.00
Monster Energy	$1.00
Red Bull	$1.75
Amp	$1.00
NOS	$2.50

The cost of energy drinks is a bit more than a bottle of soda pop.  Amp and Monster Energy are the lowest cost among these energy drinks at $1.00 per container.  NOS weighs in as the most expensive in the group at $2.50.

The Best Energy Drink Is...

The best energy drink should have a lot of caffeine, not have many calories, and should not cost very much.  I'm going to go old school for my selection of best energy drink- really old school.

Coffee is the original energy drink and has been enjoyed for over a thousand years.  Coffee compares favorably to modern energy drinks in terms of caffeine content, calories, and cost.

Caffeine Content: A 16 oz cup of coffee shop coffee has about 330mg of caffeine- more than any of the popular energy drinks in our comparison group.  If you want less caffeine, you can use ground coffee rather than grinding your own beans.  You can also mix decaf grounds with regular grounds to adjust the caffeine content to almost any level of caffeine that you desire.

Calories: Coffee naturally has almost zero calories.  If you don't like your coffee black, you can add simple things like sugar, honey, and milk that add 50 to 100 calories to a cup of coffee.  If you don't want to add any calories, you can use artificial sweeteners to create a zero calorie energy drink.  If you don't want a hot drink, you can drink an iced coffee.

Cost: You can make your own 'coffee shop' quality coffee at home for only 60 cents per 16 ounces.  This is less expensive than any of the energy drinks in our group.  If you want, you can make coffee for even cheaper if you buy less expensive coffee grounds.


Coffee wins as best energy drink based on caffeine content, calories, and cost.

How Far Would You Need to Walk to Burn off a Doughnut?

How Far Would you Need to Walk to Burn Off a ...

Walking is the simplest form of exercise.  No special equipment is needed.  You can do it indoors or outdoors.  The amount of calories burned by walking is about 100 calories per mile.  The exact amount of calories burned by walking depends slightly on body weight and walking speed, but is close to 100 calories per mile. 

If you know how many calories are in the food you want to burn off, you can easily calculate how far you would need to walk to burn off a donut, candy bar, hamburger, ice cream cone, etc.  The table below lists some typical junk food items and how far you would need to walk to burn them off.  The table also shows how long this would take at a walking pace of 4 miles per hour.

Food items, walking distance, and time required at 4 mph walking pace

Table: Food items, walking distance, and time required at 4 mph walking pace

Food Item	Calories	Distance to walk-miles	Time required-minutes
Coke or Pepsi- 16 oz	130	1.3	20
Donut- Duncan, medium	195	2.0	29
Hersheys candy bar	210	2.1	32
Medium Dairy Queen ice cream cone	330	3.3	50
Quarter Pounder with Cheese	520	5.2	78
Value meal: cheeseburger, small soda, small fries	710	7.1	107

For example, the top line of the table shows that if you drink a 16 oz Coke with 130 calories, you would need to walk 1.3 miles to burn it off and this would take 20 minutes at a 4 mile per hour walking pace.  So if you want a Quarter Pounder with Cheese, are you prepared to spend 78 minutes walking 5.2 miles to burn it off?

How Far is it to Walk a Mile to Burn off Calories?

One mile is equivalent to 17.6 football field lengths or about 8 typical city blocks.  This is the distance you need to walk to burn off 100 calories.  Keep this in mind as you are considering ordering a fast food snack!  Fatty foods contain lots of calories and if you eat calorie intense foods, it requires a lot of effort to avoid gaining weight.

How Far to Walk to Burn off X Calories?  How Long Would it Take?

The table below shows how long it takes to burn off calories by walking at various walking paces.  Average human walking speed is about 3 miles per hour.  Measurements of other walking paces show that purposeful walking is about 4 miles per hour.  The fastest most people can walk is about 6 miles per hour- this is almost like running and few people could sustain this pace very long.

Table of walking distance, calories burned, and time required at various walking paces

Table: Walking distance, calories burned, and time required at various walking paces

		Time Required- minutes
Distance- miles	Calories Burned	Leisurely 3mph	Purposeful 4mph	Fitness 5mph	Brisk 6mph
1	100	20	15	12	10
2	200	40	30	24	20
3	300	60	45	36	30
4	400	80	60	48	40
5	500	100	75	60	50
6	600	120	90	72	60
7	700	140	105	84	70
8	800	160	120	96	80
9	900	180	135	108	90
10	1000	200	150	120	100

You can use the table to see how much walking time and walking distance that extra food will cost you.  For example, if you are thinking about eating a huge meal with 1000 extra calories, you can see from the table that it would cost you 150 minutes to burn it off by walking 10 miles.

How Long Does it Take to Burn off a Pound of Fat by Walking?

Losing a pound of fat requires burning about 3500 calories.  If you burn 500 extra calories per day by walking 5 miles per day, you would lose one pound per week.  From the table above, you can see that burning 500 calories requires walking 75 minutes at purposeful walking pace.  So you would need to walk 75 minutes per day to lose one pound per week, assuming you do not increase your caloric intake.

If you are beginning an exercise program, you will likely not see a steady reduction in your weight at first.  You may gain some muscle mass- which is a good thing.  Muscles burn calories all the time, so you want to increase your muscle mass.  Also, you may hydrate more when you start exercising, so even though you will start loosing fat right away, the scale may not show that you are loosing weight until after a few weeks of increasing your exercise level.
