Everything You Want to Know About Calories - DietShake-Reviews

Do you desire to make the switch to a healthier lifestyle and want to know how calories fit into the equation?

Everything you eat contains calories, from the bagel you regretfully devoured at breakfast, to the Greek yogurt and fruit you wish you ate instead. In order to lose weight, you’re told to “watch your calories”, monitoring them in everything from food journals to fitness apps.

But what are these elusive calories anyway? And why in the world do they matter so much when it comes to your health and healthy weight?

Let’s break it down by getting the science-y stuff out of the way first…

What is a calorie?

Without getting too complicated (and forgetting about food for a minute), simply think of a calorie as a way to measure energy. We call them “calories” in the nutrition/fitness world, but they’re actually known as “kilocalories”. This is why it says “kcal” next to the amount on food labels. (1)

Calories represent the amount of energy in the food and drinks we consume. And this energy fuels our bodies (or not, if we’re eating foods void of beneficial nutrients).

How Do Calories Affect My Weight?

Your daily calorie intake and the types of food you choose directly impact your weight.

When you take in more calories per day (think energy) then you put out, your body stores the excess as fat. So basically, for weight loss, you need to eat less calories than you burn off, so that you’re also burning stored fat.

For weight maintenance, you need to consume roughly the same number of calories that you burn each day. And to gain weight, simply eat more calories than you’re going to expend.

How Many Calories Should I Eat A Day?

Note that there is not a perfect answer to this question! The number of calories you need each day depends on various factors including your overall health, physical fitness level, sex, weight, height and body shape. (2)

Since some people are more active than others, and everyone’s metabolisms work differently, the needs are different. However, you can go by an average that’s true for most people. This average, according to the US government, is as follows:

  •  Daily calorie intake requirement for the average man: 2,700 kcal per day
  •  Daily calorie intake requirement for the average woman: 2,200 kcal per day

How Do I Find My Calorie Goal for Weight Loss?

A calorie tracker helps you reach and maintain a daily calories goal.

I’m sure you’ve heard of tracking your calories in order to determine how many you need to consume a day in order to lose weight or maintain it. There are various ways to ways to do this.

Keep a Food Diary

If you’re more of the old-school type, you can keep a journal with you 24/7 and jot down everything you eat daily. Next to it, simply write down how many calories account for each item. The hard part is, you’ll have to look up the calculations yourself. And you’ll still need to figure out your daily calories goal first, using a calorie counter mechanism. Honestly, this way is more time-consuming and not the most popular.

First, You Need a Calorie Calculator…

To determine how many calories you can eat daily based on your individual body metrics (in order to lose weight) you’ll need to consult an effective calorie calculator. These tools use proven formulas to generate a specific number.

These tools use different equations to get their data. They’re all based on something called basal metabolic rate (BMR) — which is basically the amount of energy you use each day while you aren’t doing anything (at rest).

The Harris-Benedict Equation was one of the earliest trusted formulas used to calculate your BMR, and it was used primarily until 1990, when a new formula called the Mifflin-St Jeor Equation was introduced. This equation is now considered to be the most accurate today (and you will find it used most often). (3)

Or, Use A Calorie Tracker App (Recommended)

There are entire websites (and fitness apps) devoted to doing all of the hard work for you. Just input your data, and voila, it generates your daily calorie goal AND helps you stick with it.

You simply insert the food and drink items you consume, and the site logs the calories for them and keeps track of your diet, letting you know how you did each day. You can also use many of these to keep track of how many calories you burn. And the best part… most of the sites are free (unless you want to use upgraded features for a cost).

Some of the most popular current apps/websites include:

  • MyFitnessPal
  • Lose It!
  • FatSecret
  • Cron-o-meter
  • SparkPeople

Calories and Your Health

Use a calorie tracker to keep up with your daily calories goal.

Think of calories as fuel that you’re putting into a car, and your body is the car. In order to be as healthy as possible, you need to give your body the best energy, so you can thrive and get the things done that you need to do.

If you give your body bad fuel, you’re going to be tired, lack mental focus and drive, and potentially gain weight. The best way to ensure you’re giving your body quality foods that support a healthy, clean diet, is to stay away from empty calories. These provide energy but for very little nutritional value.

Foods with “empty calories” are generally lacking:

  • Fiber
  • Amino acids
  • Antioxidants
  • Dietary minerals
  • Vitamins

Mainly, these empty calories come from two major places:

Solid fats– As the name implies, these fats are solid at room temperature. Examples include butter, beef and chicken fat, cream, lard, shortening, margarine, hydrogenated and partially hydrogenated oils and coconut oil. The common denominator in all of these is that most are high in the “bad fats”, saturated and/or trans fats, and have less of the “good fats”, monosaturated or polyunsaturated fats. (4)

Added sugars– These sweeteners are added to foods and drinks during the manufacturing process. The main sources in American diets include: soft drinks, candy, cakes, cookies, pastries, fruit drinks and ice cream. (5)

How Can Meal Replacement Shakes Help Me with My Calorie Goal?

Gives a Set Number of Calories Per Meal

Since meal replacement shake powders have a set number of calories per serving (and you use them to replace regular meals) it makes it much easier to keep track of your calories from all your meals.

If you make smoothies with the shake powder using other ingredients, such as low-fat milks, fruits or veggies, simply add those ingredients into your calorie-tracking app, or into your food journal as well.

Helps Keep Your Daily Calorie-Count Low

Drinking meal replacement shakes is also a great way to keep your daily calorie intake low, since many of them have a nice low number of calories per serving – while also providing a great amount of beneficial nutrients.

Look for a diet shake that has around 100 calories or less ideally, but if they have more than just avoid adding high-calorie ingredients with it into smoothies.

Helps You Avoid Empty Calories

To avoid empty calories, also look for shakes that don’t have a lot of sugar. And make sure they’re well-balanced for a nourishing meal. They should contain optimal protein (15-20g), sufficient fiber (5-10g), and a plethora of vitamins, minerals and even superfoods.

What Else Can I Do to Keep My Calories in Check?

A healthy lifestyle makes all the difference in whether or not you stick with a daily calorie goal. And it also goes beyond just your diet. Two additional healthy lifestyle practices to follow include getting adequate hydration (making sure you get enough water each day) and exercise.

Get Needed H2O

Often, when we think we’re hungry, we’re actually thirsty, and our body is telling us we need more water. Staying hydrated is a great way to keep your calories lower by avoiding snacking on high-calorie foods when hunger strikes.

Exercise Weekly

Your weekly schedule should also include an exercise plan that works with your lifestyle. Ideally, it should include both cardio and some type of strength training. But it can be any type of physical activity you enjoy doing such as running, hiking, biking, swimming or dancing.

Whatever you decide to do, consider adding weight-lifting to your routine. Lifting weights has been shown to help prevent muscle loss as we age, along with the slowing of your metabolism. It’s also a great way to build lean muscle, which in turn helps your body burn more calories than you would normally. (6)
