Calorie Calculator – Daily Caloric Needs

How Many Calories Should I Eat?

Fixed calorie recommendations do not work. They must be customized to each individual.

The calculator shows how many calories you may eat in order to maintain or lose weight. Do your best estimate of how much exercise you will be stick to. Be honest.

The recommended calories include your exercise – so don't mess around with trying to adjust what you are eating each day if you had a workout.

Over time, as you lose weight you will need to recalculate based on your new weight. Also, if you make big changes to your workout (reducing or increasing) you should also recalculate.

Calories for Fat Loss

Science tells us that 1 pound of fat is equal to 3500 calories, so a daily calorie deficit of 500 should result in 1 pound per week fat loss.

In reality things don't quite work that efficiently.

Generally, a person's energy expenditure becomes less as they get lighter – meaning that you will inevitably plateau. The amount of food intake that once resulted in weight loss, will now only maintain².

Take It Gently

Always try to aim for the "Fat Loss" daily calorie level.

The "Extreme Fat Loss" level is effectively a rock bottom calorie level. Do not attempt to immediately drop your calories to this level hoping for the quick fix. This may ultimately backfire.

The Extreme Fat Loss level shows the lowest calorie amount that can be considered. It should be seen as the exception rather than the rule.

It truly is better to burn the fat than to starve it.

The Weight Loss Plateau

Why use the 7-day Calorie Cycle (Zig-Zag)?

The human body is remarkably adaptive and quickly adjusts to a lowered calorie level.

It becomes more efficient at using energy (lowered metabolism), and therefore burns less fat. This is why most of us reach a weight loss plateau.

At this point, the only option is to change something:

increased cardio,
weight training,
'cheat' meals (i.e. occasional high-calorie meals),
cycling (or zig-zagging) calories,
even manipulating macro-nutrient ratios can all help to do this (don't forget adequate sleep and hydration).

You often find that the nearer you get to your goal weight (or body fat percentage) – the harder things get!

Continually dropping calories only serves to lower metabolism even further – the moment you return to 'normal' eating – the weight comes back on. The 7 Day zig-zag provides a suggestion for daily calories that will keep your body guessing – and increase your chances of continual weight loss.

Minimum Daily Calorie intake

It is difficult to set absolute bottom calorie levels, because everyone has different body composition and activity levels.

Health authorities do set some baselines – these are 1200 calories per day for women, and 1800 calories per day for men.

These rules don't make sense – are you are sedentary person with little muscle mass? Or someone who is tall, muscular, and exercises a lot? Absolute levels don't work – but do give us a starting point.

When reducing calories:

Try not to lower your calorie intake by more than 500 calories below maintenance.

Doing so may invoke the bodies starvation response, which can lead to the Yo-yo dieting effect.

Try to gradually lower calories. A sudden drop (such as 500 calories or more) can cause your metabolism to slow.

Learn to eat slowly – research shows that faster eaters are heavier people¹.

What happens when calories are too low?

Muscle mass is broken down for energy (catabolism).
Metabolic rate will begin to drop (typically) after 3 days of very low calories – this is related to, and compounded by the loss of muscle mass.
With very low calories you risk sluggishness, nutritional deficiencies, fatigue, and often irritability.

You are completely set-up for a regain in fat if you suddenly return to your previous eating patterns.

Exercise Level

As your exercise level was already factored into the equation, there is NO NEED to subtract calories burned by exercise.

For the sake of simplicity we define a 'workout' as 15-30 minutes of elevated heart rate.

For you this could mean a brisk walk, for others it could be a slow jog. It could be a session of weight-bearing exercises.

Intense exercise can be defined as an hour of elevated heart rate (however intense workouts such as a series of body weight exercises (or heavy weights) with little or no breaks are considered intense even when only a shorter duration).

Estimating your exercise can be very arbitrary. If in doubt – underestimate. We all tend to overestimate how much exercise we do.

Have a play with our calories burned tool to see how different exercises compare.

You can lose weight without exercise, but do aim to include exercise in your lifestyle change: it maintains muscle when under calorie deficit, and is great for your heart and mental state.

Programs That Work

POPULAR Noom is one of the most individualized and comprehensive programs out there that take in all factors (physical, psychological, nutrition). The factors combine to form a unique program that's backed by research.

Fat Loss Calories Around 1200?

If you have the budget, Diet-to-go have a delivered meal plan that sits exactly at 1200 calories. It's about $122 per week (or $144 including breakfast / lunch / dinner).

Lose Fat and Build Muscle?

Most people lose muscle mass when restricting calories. It takes effort to maintain muscle tone – and is even more tricky actually building muscle while losing fat (hint: a comprehensive workout plan is needed).

Old School New Body from Steve Holman is a great program that focuses on shorter workouts (maximum 90 minutes per week), while losing fat and building muscle. Age is no excuse here as the author is ripped and in his 50s !
