Step 1: Set & Track Your Calories and Macros
If you want to lose body fat you’ll need to be in a calorie deficit, and there are a ton of different ways to create a calorie deficit with different diets like high carb or low carb, paleo or vegan diets.
Any of these diets have worked for someone trying to lose fat. No diet is magic but they all have different ways of creating a calorie deficit.
This section of the blog will help you set your calorie and macronutrient intake for fat loss.
Keep in mind that this is a framework for you to build off and make adjustments to, it’s not set in stone or perfect from the jump but it will be a good starting place.
If you prefer low carb or high carb or want to set protein higher or lower than is up to you.
The first thing we’ll need to find is the amount of calories you require to maintain your bodyweight. Once we know this we can figure out your calorie deficit for fat loss.
There are a lot of formulas and calculators out there to establish what your baseline calorie intake should be, but I like to keep things as simple as possible.
To find an estimate of the amount of calories you need to maintain your weight simply multiply your bodyweight in pounds by 13-17.
The reason for the wide range of 13-17 is based on a number of factors such as: height, gender and daily activity.
If you have a pretty sedentary job that requires a lot of sitting or you’re a smaller woman choose the lower 13-15 end of the spectrum.
If you have a high output like a manual labor job, or lead a really active lifestyle with 3-5 trips to the gym week, I’d go with the higher end of the spectrum 16-17.
If you’re a 165 pound male who works at a desk all day and isn’t all that active but goes to the gym to train 3 times a week multiply your bodyweight by 14-15.
165 lbs X 14-15 = 2,310 - 2,475 calories for maintenance
Now a 165 pound male who works an intense manual labor job and trains 4 times per week would use 17.
165 lbs x 17 = 2,805 calories for maintenance
A woman who’s 125 pounds and works a job where she’s on her feet all day and trains 4 times a week should go with 15.
The reason why she would go with 15 instead of the 16-17 range is because she has a lower body weight and as a result her basal metabolic rate (BMR) would be lower.
125 lbs x 15 = 1,875 calories for maintenance
Conversely a woman who’s 125 lbs works at a desk job for the majority of her day and hits the gym 2-3 times per week would would go with 13.
125 lbs x 13 = 1,625 calories for maintenance
Setting A Calorie Deficit:
In the beginning a good start is to reduce calorie intake by 20% so you can get some initial fat loss.
Moving forward after you’ve set the initial calories and hit a legitimate fat loss stall you’d reduce your calorie intake by 5-8%. The goal is to always eat as much as possible while losing at a steady rate.
Let’s use our 165 pound male who works an intense manual labor job and trains 3 times per week as an example here.
165 lbs x 17 = 2,805 calories for to maintain body weight (maintenance)
2,805 (maintenance cals) X 0.20 = 561 calories
2,805 (maintenance cals) - 561 (cals) = 2,244
Calorie intake for fat loss: 2,244
Putting It All Together:
To help put this all together in an example let’s use a 165 pound male who works at a desk all day and isn’t all that active other than going to the gym to train 3 times a week.
Your Macro Breakdown:
For the sake of making things simple let’s use some easy ranges:
Protein: 1 gram per pound of bodyweight
Carbs: Remainder of calories
If you need to adjust the macros for your own taste/preference or needs just follow the steps below and make changes where it applies.
You’re getting the step by step process on how I’m doing it all below so you can make the changes based on your needs.
If you need help understanding something below please hit reply so I can help you, but I don’t have the time to calculate everyone’s individual macros for them.
An important thing to keep in mind is the different caloric content of the macros, which comes into play below:
1 gram carbohydrates = 4 calories
1 gram of protein = 4 calories
1 gram of fat = 9 calories
We’ll need to go through and do some math to figure all this out.
165 Lb male with a desk job who trains at the gym three times per week:
165 lbs X 14 = 2,310 calories for maintenance
Now we’re going to find how many calories he’ll need to eat to lose body fat.
2,310 (calories for maintenance) x 0.20 (20% calorie deficit) = 462 calories
2,310 (calories for maintenance) - 462 calories (creating a calorie deficit) = 1,848
Calories for fat loss: 1,848
1. ) Configuring Protein
165 lbs = 165 G
165 x 4 (calories per gram of protein) = 660 calories
Grams of Protein: 165 G
2.) Configuring Fats:
Fat loss calories: 1,848 x 0.3 (30% fats) = 554.4 calories from fat
Now to see how many grams of fat that translates into we need to divide those calories by 9 because that’s how many calories are in each gram of fat.
554.4 (calories from fat) / 9 ( 9 calories per gram of fat) = 61.6 ( 62 G )
Grams of Fat: 62 G
3.) Configuring carbs:
Add protein and fat calories together and subtract from total fat loss calories to find calories from carbs.
660 calories (protein cals) + 554 calories (fat cals) = 1,214
1,848 (fat loss calories) - 1,214 calories = 634 calories from carbs
To see how many grams of carbs that translates into we need to divide those calories by 4 because that’s how many calories are in each gram of carbs.
634 (calories from carbs) / 4 (4 calories per gram of carb) = 158.5 (159 G )
Grams of Carbs: 159 G
Our example 165 lb male’s calories and macros for fat loss would be:
Calorie Intake: 1,848 calories per day
Carbs: 159 gram per day
Protein: 165 gram per day
Fat: 62 grams per day
Step 2: Have Spike Days and Diet Breaks
Your body is especially good at adapting for survival so when it’s put in a controlled state of starvation, which dieting for for fat loss is, it will create shortcuts necessary to conserve energy.
These shortcuts come in the way of making you burn fewer calories, increasing your hunger, causing hormonal dysfunction and slowing down thyroid function.
For those who have been in an aggressive calorie deficit consistently for 8-12 weeks; implement spike days and diet breaks.
Spike days and diet breaks help restore hormones levels, prevent some metabolic adaptations and give you a psychological break from dieting.
A spike day is once or twice per week purposefully increasing your calories by 300-600. Depending on how lean you are and how long you’ve been dieting.
This is not a “cheat” day because you’ll need to keep fat intake lower, and have the majority of these calories come from carbohydrates.
Carbohydrates are the most effective macronutrient at boosting leptin and thyroid levels, which mitigates the metabolic adaptations that make fat loss more difficult.
A full diet break is returning your calorie intake to a maintenance level for 1-2 consecutive weeks after an 8-12 week block of fat loss dieting.
You will likely gain a few pounds of weight when on a diet break, and this especially true for people who have been using a low carb diet.
This is not a cause for concern as most of the weight will be from water storage and increased muscle glycogen (carbohydrates stored in the muscle).
You will be eating more for so there will also be more food in the digestive system as well.
