Beginner Guide to Calorie Math: Simple Fat Loss Tools

Figuring out calorie math felt completely overwhelming the first time I tried it, sitting at my kitchen table in Seattle, surrounded by three different nutrition websites, all giving me different numbers. Nobody was explaining it in plain language. Everything assumed I already knew the basics. This beginner guide to calorie math is what I wish I’d had at the start: clear, simple, practical, and built on real math rather than guesswork. By the end, you’ll know your numbers, understand your tools, and have a real system you can actually use.

What Is Calorie Math (And Why It Matters)?

Calorie math sounds intimidating. It really isn’t. At its core, it’s just energy in versus energy out, with enough structure to make that information useful. Once you grasp the basic equation, fat loss, muscle gain, and maintenance all become logical and predictable rather than confusing and random.

What Is a Calorie, Really?

A calorie is a unit of energy. That’s the complete definition. Your body needs energy for everything it does, breathing, pumping blood, digesting lunch, walking to the fridge for that midnight snack you keep telling yourself you won’t have.

The National Institutes of Health explains that the calories in food represent chemical energy your body converts into the fuel it needs to function. Think of it like gasoline in a car. Too little and you stall. Too much and the overflow has to go somewhere, in your body’s case, that somewhere is stored fat.

Here’s the sensory picture I keep in my head. Morning coffee, that warmth and clarity kicking in. The mid-afternoon slump when lunch starts wearing off. That gnawing evening hunger when dinner feels hours away. All of those feelings are calorie math playing out in real time. Your body is communicating its energy status constantly. Calorie math just gives you the language to understand it.

The Energy Balance Equation

Everything in fat loss and weight management comes back to this:

1. Calories In: all food and drink you consume
2. Calories Out: your BMR (resting burn) + physical movement + the energy used to digest food

If you eat 2,200 calories but your body burns 1,900, it stores the extra 300. Do that consistently and weight goes up. Flip it, eat 1,700 when you burn 2,000, and your body pulls from fat stores to make up the 300-calorie gap. Do that consistently and weight comes down.

Your body is basically a very polite accountant. It tracks everything, records every transaction, and never forgets a deposit or withdrawal. The math always balances, eventually.

Why Beginners Overcomplicate It

Most beginners struggle not because calorie math is hard, but because they encounter the hardest version first. Here’s what I see most often:

1. Following an influencer’s macros blindly without knowing their own maintenance number
2. Copying 1,200-calorie plans that work for someone else’s body size and activity level
3. Ignoring activity level differences, a college student in Texas playing intramurals burns very differently than a desk worker in New Jersey
4. Trusting smartwatch calorie burn numbers as precise measurements rather than directional estimates

Calorie math done simply, with just two or three key numbers, is genuinely beginner-friendly. We’re going to do it that way.

Understanding Your Baseline: BMR Explained

Before you can subtract calories from anything, you need to know your starting number. That number is your BMR, and it’s the foundation everything else builds on.

What Is BMR?

BMR stands for Basal Metabolic Rate. It’s the number of calories your body burns at complete rest, just to keep you alive with no movement at all. Imagine lying in bed all day without getting up. Your heart is still beating, your lungs are still breathing, your brain is still processing, your organs are still running. That baseline energy cost is your BMR.

For most adults, BMR accounts for 60-70% of total daily calorie burn. It is by far your largest energy expenditure, and it happens without you doing anything at all.

Two widely used formulas for calculating BMR are the Mifflin-St Jeor equation and the Harris-Benedict equation. The Mifflin-St Jeor formula is generally considered the more accurate modern standard and is the one most professional nutrition tools use.

Step-by-Step: How to Calculate Your BMR

Here’s the Mifflin-St Jeor formula written in plain language:

1. For men: (10 x weight in kg) + (6.25 x height in cm) – (5 x age) + 5
2. For women: (10 x weight in kg) + (6.25 x height in cm) – (5 x age) – 161

Let’s walk through a real example. Jake is 34 years old, lives in Denver, and works a desk job. He’s 5’10” and weighs 200 pounds. Here’s his BMR calculation step by step:

1. Weight: 200 lbs = 90.7 kg
2. Height: 5’10” = 177.8 cm
3. Age: 34
4. Formula: (10 x 90.7) + (6.25 x 177.8) – (5 x 34) + 5 = 907 + 1,111.25 – 170 + 5= 1,853 calories per day

Jake’s BMR is approximately 1,853 calories. That’s what his body burns just to stay alive at rest. But Jake doesn’t lie in bed all day, he walks his dog every evening and moves around at work. So his actual daily burn is higher. That’s where TDEE comes in.

TDEE, Your Real Daily Calorie Needs

TDEE, Total Daily Energy Expenditure, is the number that actually matters for calorie planning. It’s BMR adjusted for how active you really are. This is the number you eat at to maintain your current weight.

What Is TDEE?

TDEE = BMR multiplied by an activity factor. The American Council on Exercise and most professional nutrition frameworks use these standard activity multipliers:

1. Sedentary (1.2): desk job, minimal movement, no formal exercise
2. Lightly active (1.375): light exercise 1-3 days per week
3. Moderately active (1.55): moderate exercise 3-5 days per week
4. Very active (1.725): hard exercise 6-7 days per week
5. Extremely active (1.9): physical job plus daily intense training

Back to Jake. He walks his dog every evening and gets light activity at work, lightly active fits him best. His TDEE: 1,853 x 1.375 = approximately 2,548 calories per day. That’s what he burns in a normal day. Eat at 2,548 and his weight stays stable. Eat less and he loses & eat more and he gains.

Estimated Daily Maintenance Calories by Weight and Activity

After working through beginner calorie math with people in Chicago and Tampa, I’ve seen consistent patterns. These ranges are realistic, not Instagram numbers, not extreme diet targets, but what real people at these body weights actually need to maintain their current weight.

Body Weight	Sedentary	Lightly Active	Moderately Active
140 lbs	1,650-1,750	1,800-1,900	2,000-2,100
160 lbs	1,750-1,850	1,900-2,050	2,150-2,300
180 lbs	1,850-2,000	2,050-2,200	2,300-2,500
200 lbs	1,950-2,100	2,150-2,350	2,450-2,650
220 lbs	2,050-2,200	2,300-2,500	2,600-2,800

Important caveats: age matters, metabolic rate declines gradually with age. Muscle mass matters, more muscle means higher BMR. Sleep quality and chronic stress also shift actual burn. These ranges are starting points. Real-world tracking over 2-3 weeks is what gives you a personalized, accurate number.

Creating a Calorie Deficit (For Fat Loss)

This is what most beginners are actually searching for. Everything above was the foundation. Now comes the application: how to use calorie math to lose fat safely and sustainably.

Safe Deficit Range

A daily deficit of 300-500 calories below your TDEE is the research-supported sweet spot for sustainable fat loss. This produces approximately 0.5-1 pound of fat loss per week, a pace that is slow enough to preserve muscle, maintain hormonal health, and keep hunger manageable.

The Academy of Nutrition and Dietetics consistently emphasizes that gradual fat loss, rather than rapid extreme restriction, produces better long-term outcomes because it protects lean tissue and creates habits that hold up past the diet phase.

“Slow fat loss protects metabolism and muscle,” says Dr. Rachel Monroe, RD, a Dallas-based registered dietitian. “A 300-500 calorie deficit is where most of my beginner clients see the best balance of results and sustainability. Going deeper than that creates problems faster than it creates progress.”

A Real Fat Loss Scenario, Emily in Phoenix

Emily is 41 years old and lives in Phoenix. She works a moderately active job and has a TDEE of approximately 2,000 calories per day. She wants to lose about 15 pounds over the next few months.

Here’s her calorie math:

1. TDEE (maintenance): 2,000 calories
2. Target deficit: 400 calories per day
3. Daily calorie target: 1,600 calories
4. Weekly calorie deficit: 400 x 7 = 2,800 calories
5. Fat loss pace: approximately 0.8 lbs per week

One pound of body fat stores approximately 3,500 calories. A consistent 400-calorie daily deficit creates a weekly deficit of 2,800 calories, producing close to one pound of fat loss per week. Over 15 weeks, that’s Emily’s 15 pounds gone with no starvation and no extreme restriction.

Signs Your Deficit Is Too Aggressive

Bigger deficits don’t always mean faster useful results. A deficit that’s too deep triggers metabolic adaptation and makes the whole process harder. Watch for these warning signs:

1. Constant fatigue that sleep doesn’t fix
2. Noticeable drop in gym performance or daily energy
3. Cold hands and feet, a classic sign of metabolic slowdown
4. Weight loss plateau after an initial fast drop
5. Intense, difficult-to-manage cravings
6. Mood problems and irritability out of proportion to daily stress

If your coworkers start asking why you’re snapping at emails, check your calories. That’s not a personality change, that’s ghrelin talking. Pull back to a more moderate deficit and watch how quickly everything normalizes.

Creating a Calorie Surplus (For Muscle Gain)

Not everyone doing calorie math is chasing fat loss. Some people want to build muscle, and doing that effectively requires eating above maintenance. This is where a calorie surplus comes in.

Safe Surplus Range

A surplus of 200-300 calories above TDEE is the recommended range for lean muscle gain. The American College of Sports Medicine identifies this as sufficient to support muscle protein synthesis when combined with consistent resistance training, without producing excessive fat gain alongside the muscle.

More calories than that doesn’t accelerate muscle building, muscles have a growth rate ceiling. The extra calories just become extra fat. The goal is to stay as close to the minimum effective surplus as possible while hitting protein targets.

Clean Bulk vs Dirty Bulk

A clean bulk means eating at a controlled surplus with high-quality food sources, lean proteins, whole carbohydrates, healthy fats, to support muscle growth while minimizing fat accumulation. A dirty bulk means eating everything in sight and telling yourself the weight gain will sort itself out later. It rarely does.

Adding two spoonfuls of peanut butter to your oatmeal is a clean bulk addition, quality calories, good protein and fat profile. Hitting a drive-thru every night because you ‘need the calories’ is a dirty bulk, you’ll gain the surplus and then some, with a much higher fat-to-muscle ratio.

Track your weekly weight gain during a bulk. Gaining more than 0.5 pounds per week? Reduce the surplus slightly. Gaining nothing over two weeks? Increase by 100-150 calories. The math guides you.

Tools for Calorie Math (The Practical Core)

Understanding the math is step one. Having the right tools to apply it consistently is step two. These are the tools I’ve used personally and recommend most often for beginners.

Calorie Tracking Apps

Food tracking apps are the most direct tool for applying calorie math daily. Each has different strengths:

1. MyFitnessPal: the most widely used beginner app, large food database, barcode scanning, easy logging, solid macro tracking
2. Cronometer: stronger on micronutrient detail, ideal if you want to track vitamins and minerals alongside macros
3. Lose It!: the cleanest interface of the three, fastest to log, very beginner-friendly, less overwhelming than MyFitnessPal

All three pull from large food databases, though database accuracy varies. For packaged foods with barcodes, all three are highly accurate. For homemade meals and restaurant foods, manual entry introduces some estimation. The key for beginners isn’t perfect accuracy, it’s consistent tracking that builds awareness over time.

Wearables and Smart Devices

Apple Watch, Fitbit, and similar wearables estimate calorie burn throughout the day using heart rate, movement sensors, and algorithmic modeling. They’re genuinely useful for tracking activity trends and staying aware of movement patterns.

One important note: wearable calorie burn estimates are not precision measurements. Research consistently shows they overestimate calorie expenditure, sometimes by 20-40%. Use them for directional guidance and daily activity awareness rather than precise calorie targets. If your Apple Watch says you burned 2,800 calories today, treat that as an indicator, not a green light to eat exactly 2,800 calories.

Best Tools for Beginners, Comparison

After personally testing these tools over several months, yes, logging even Thanksgiving dinner, which is both an educational and humbling experience, here’s what stands out for different beginner needs.

Tool	Best For	Ease of Use	Accuracy Level
MyFitnessPal	General beginners, large database	Very Easy	Moderate, database varies
Cronometer	Nutrient detail, health-focused tracking	Medium	High, verified data
Lose It!	Simplicity and speed	Easy	Moderate, good for basics
Apple Watch	Activity tracking and trends	Easy	Moderate, overestimates burn
Digital kitchen scale	Portion accuracy for home cooking	Easy	High, most reliable tool

Understanding Macros (Without Going Crazy)

Calorie math gives you your total number. Macronutrient math tells you where those calories come from. For beginners, you don’t need to obsess over exact macro splits, but understanding the basics helps you make smarter food choices within your calorie target.

Protein, The Most Important Macro During Fat Loss

Protein is the macronutrient that preserves muscle during a calorie deficit. It also increases fullness more effectively than carbohydrates or fat, reducing hunger between meals. And it has the highest thermic effect, about 20-30% of protein calories are burned during digestion.

The standard recommendation for people managing their weight is 0.7-1 gram of protein per pound of goal body weight daily. For Emily in our earlier example, targeting 120-140 lbs means aiming for 120-140 grams of protein per day.

Good sources: chicken breast, fish, eggs, nonfat Greek yogurt, cottage cheese, lentils, and canned tuna. Distribute protein across meals rather than concentrating it in one sitting, it keeps satiety hormones more stable throughout the day.

Carbohydrates, Your Body’s Preferred Energy Source

Carbohydrates get an unfairly bad reputation in diet culture. Your brain runs almost exclusively on glucose, a carbohydrate. Your muscles use glycogen, stored carbohydrate, for training intensity. Dietary fiber, which is technically a carbohydrate, supports gut health, cholesterol management, and long-term metabolic health.

Oatmeal on a cold Ohio morning just hits different. That warm, slow-digesting bowl of oats keeps you full and energized for hours in a way that a low-carb alternative often doesn’t. Carbohydrates aren’t the problem. Excess refined carbohydrates, white bread, sugary drinks, processed snacks, eaten in calorie surplus are the problem.

For calorie math purposes, carbohydrates provide 4 calories per gram. Fill your carbohydrate allowance with fiber-rich whole foods, vegetables, legumes, whole grains, fruits, and the satiety benefits compound.

Fats, Essential, Not Optional

Dietary fat is essential for hormone production, brain function, joint health, and the absorption of fat-soluble vitamins A, D, E, and K. The Harvard T.H. Chan School of Public Health consistently identifies healthy fat sources, olive oil, avocados, nuts, fatty fish, as components of diets associated with long-term health and healthy weight management.

Fat provides 9 calories per gram, more than double protein or carbohydrates. This means small portions of fatty foods add calories quickly. One tablespoon of olive oil is 120 calories. A quarter cup of almonds is 170 calories. These aren’t reasons to avoid fat, they’re reasons to measure it.

Common Beginner Mistakes in Calorie Math

This is where most people stumble, not because they’re lazy or unmotivated, but because they’re human. These mistakes are almost universal among beginners. I made most of them myself.

Eyeballing Portions

Visual estimation of food portions is one of the most studied sources of calorie tracking error. Research consistently shows people underestimate portion sizes by 20-50% when relying on sight alone, especially for calorie-dense foods.

The peanut butter problem is the classic example. What looks like a tablespoon serving, a modest, reasonable amount, usually turns out to be two or three tablespoons when actually measured. That’s 95 calories versus 285-380. A ‘small handful’ of almonds? Often 200+ calories rather than the 100 calories people assume.

Use a food scale for the first 30-60 days. It builds accurate portion intuition that persists long after you stop weighing every meal. The calibration it provides is genuinely worth the extra 60 seconds per meal.

Ignoring Liquid Calories

Liquid calories don’t trigger the same satiety signals as solid food, but they absolutely count toward your daily total. This is where many beginners have a significant untracked calorie gap.

Common liquid calorie sources that add up faster than expected:

1. Flavored coffee drinks, a medium latte with flavoring syrup can be 300-400 calories
2. Juice, a glass of orange juice is 110+ calories with almost no fiber
3. Sports drinks, often 150-200 calories per bottle
4. Alcohol, beer is 150 calories, wine 120-150 per glass, cocktails vary widely
5. Sweetened teas and sodas, 150+ calories per can

Swapping one large flavored coffee per day for black coffee or unsweetened tea eliminates 250-400 daily calories without changing a single bite of food. That’s one of the highest-leverage calorie adjustments a beginner can make.

Not Weighing Food

Measuring cups are better than nothing, but they introduce volume variability that weight measurement eliminates. The same measuring cup of oats can hold different amounts depending on how packed it is. Weight doesn’t vary. 80 grams of oats is 80 grams every single time.

A basic digital kitchen scale is a $10-15 investment that produces meaningfully more accurate calorie tracking immediately. It’s the single highest-leverage tool upgrade a beginner can make after downloading a tracking app.

Real-Life Day of Calorie Math (Practical Walkthrough)

Abstract concepts become real when you walk through them step by step. Here’s how I’d log a realistic Tuesday for a beginner client, approximately 2,000 calories total, which represents maintenance for many moderately active adults.

Morning, Coffee and Breakfast

The day starts with coffee and the first food decision. Here’s how the morning typically shakes out:

1. Black coffee with 2 tbsp half-and-half: approximately 40 calories
2. 2 scrambled eggs: approximately 140 calories
3. 2 slices whole-grain toast: approximately 160 calories
4. 1 tbsp butter on toast: approximately 100 calories
5. Morning total: approximately 440 calories

Notice the butter. That’s where beginners often lose 100 calories without realizing it, spreading it on without measuring. One tablespoon is easy to eyeball as half a tablespoon or double that depending on the day. Weighing it takes five seconds.

Lunch at Work, The Midday Meal

Lunch is where many people either crush their calorie budget or stay well within it based on one or two choices.

1. Grilled chicken bowl: 4 oz chicken, half cup brown rice, black beans, salsa, lime: approximately 500 calories
2. Can of sparkling water: 0 calories
3. Lunch total: approximately 500 calories

Compare that to the same chicken bowl with a regular soda (150 calories) and a dressing addition (100-200 calories) and lunch jumps to 750-850 calories, same food, very different calorie math. Small choices at each meal compound across the day.

Dinner and Evening Snack

Dinner is where the biggest calorie variability tends to happen, portion sizes, cooking oils, and added extras shift the total significantly.

1. Pasta dinner: 2 cups cooked pasta, tomato sauce, lean ground turkey: approximately 600 calories
2. Measured 1 tbsp olive oil in cooking: 120 calories
3. 2 squares dark chocolate for dessert: approximately 100 calories
4. Dinner and snack total: approximately 820 calories

Sample Day Breakdown, Total Calorie Accounting

This is how I’d log a realistic weekday for a beginner client in Atlanta. The goal isn’t perfect, it’s aware.

Meal	Foods	Approximate Calories
Breakfast	Eggs, toast, coffee with creamer	400
Lunch	Chicken bowl, sparkling water	500
Afternoon snack	Greek yogurt, small apple	250
Dinner	Pasta, turkey, olive oil, dark chocolate	850
Total	—	2,000

Two quick adjustments to reduce that by 300-400 calories if needed for fat loss: swap the soda at any meal for water (saves 150 calories), reduce pasta portion from 2 cups to 1.5 cups (saves about 110 calories), and skip the butter at breakfast (saves 100 calories). Same food, same satisfaction level, 350 fewer calories. That’s the practical power of calorie math.

How Long Before You See Results?

Everyone asks this. It’s the most common question I get. The honest answer is: it depends, but the timeline is more predictable than people expect once the math is working.

Week 1-2: The Adjustment Phase

The first one to two weeks of calorie tracking and a moderate deficit often produce scale movement that’s partly water weight, not fat. Reducing carbohydrate intake causes glycogen (stored carbohydrates) to deplete, and glycogen holds water, roughly 3 grams per gram. Losing glycogen produces rapid initial weight drop that isn’t fat loss.

This is also the learning curve phase. Logging accurately takes practice. Portion sizes feel unfamiliar. Your body is adjusting to the new intake level. Don’t judge the method based on the first two weeks. Use them to build the habit.

Week 3-6: Consistency Starts Paying

By week three, the initial water weight fluctuation has settled and genuine fat loss starts becoming measurable. A consistent 400-500 calorie daily deficit produces 0.8-1 pound of fat loss per week at this stage.

Over a 6-week consistent period, that’s 5-6 pounds of actual fat loss, not dramatic on a scale day-to-day, but meaningful and visible. Clothes start fitting differently. Energy levels stabilize. The habit of logging becomes automatic rather than effortful.

The 90-Day Expectation

Ninety days of a consistent 400-calorie daily deficit produces approximately 10-11 pounds of fat loss while protecting muscle mass. That’s a meaningful transformation, visible in the mirror, measurable on the scale, and felt in how clothes fit.

That first time your jeans button easier without having to hold your breath? That’s a quiet victory. Not dramatic, not Instagram-worthy in the moment, but real. And it’s built entirely on calorie math done consistently over three months.

When to Seek Professional Guidance

Calorie math is powerful for most healthy adults. But it’s not universally appropriate without professional support. Certain situations call for expert guidance before and during any calorie management approach.

Medical Conditions That Require Professional Input

The Centers for Disease Control and Prevention identifies several health conditions where dietary changes, including calorie restriction, should be managed with medical oversight:

1. Type 1 or Type 2 diabetes, calorie reduction affects blood sugar management and medication dosing
2. Thyroid disorders, hypothyroidism affects metabolic rate in ways formulas don’t account for
3. PCOS (Polycystic Ovary Syndrome), hormonal factors affect weight loss response differently than standard calorie math predicts
4. Cardiovascular disease, dietary changes may interact with medications and treatment protocols
5. Kidney disease, protein recommendations differ significantly from standard weight management guidelines

If you have any of these conditions or take medications that affect metabolism or weight, work with your physician and a registered dietitian before setting calorie targets based on online calculators alone.

History of Disordered Eating

Calorie tracking can be an effective tool for most people. For people with a history of eating disorders, anorexia, bulimia, binge eating disorder, or orthorexia, calorie counting can reinforce harmful thought patterns and behaviors.

If food tracking has previously created obsessive thinking, anxiety around meals, or disordered behaviors, please work with a registered dietitian and a mental health professional rather than applying calorie math independently. There are approaches to weight management that don’t require numerical tracking, and for some people, those approaches are significantly healthier.

Expert Insight: USA Dietitian Perspective

“Calorie math isn’t about perfection. It’s about awareness,” says Dr. Lisa Hernandez, RD, a Miami-based clinical nutritionist. “I tell beginner clients to track for two weeks before making any changes at all. Just observe. What you discover about your current habits, how many liquid calories you’re consuming, how large your portions actually are, where the hidden calories live, is more valuable than any formula. Then you adjust gently, based on real data rather than guesses. That approach works because it builds insight, not just compliance.”

That philosophy has shaped how I approach calorie math with beginners. Start with awareness. Track your current reality before changing it. Adjust based on what you learn. The math tells you where to go, but observation tells you where you actually are.

Final Thoughts: Making Calorie Math Sustainable

Calorie math is a tool. The goal was never to turn you into a human spreadsheet who calculates every bite forever. The goal is to understand your body’s energy needs well enough to make informed decisions, and to have that understanding work in the background of a normal life.

Progress over perfection. Every week you track consistently, even imperfectly, builds more awareness than the most carefully planned week you can’t maintain. A realistic, slightly imperfect approach sustained for months beats a perfect approach abandoned in two weeks.

You don’t need a spreadsheet for life. Just enough math to understand your body. Once you have that, and you will, faster than you expect, it becomes second nature.

Final Recommendation

After years of applying this personally and walking beginners through the same process, here is my clear, direct recommendation for anyone starting with calorie math:

Step one: calculate your TDEE. Use the Mifflin-St Jeor formula for BMR and multiply by the activity factor that honestly reflects your daily life.

Step two: track your current eating for two weeks before changing anything. Just observe. Use MyFitnessPal, Cronometer, or Lose It, whichever feels most natural.

Step three: set a 300-500 calorie daily deficit below your TDEE. Not 1,200 calories. Not whatever an influencer eats. Your TDEE minus 300-500. That number is your personal fat loss target.

Step four: hit your protein target every day. Set it at 0.7-1 gram per pound of goal body weight and treat it as non-negotiable. Protein protects muscle during a deficit, increases satiety, and produces the highest thermic effect of any macronutrient.

Step five: use a kitchen scale for high-calorie, high-density foods, oils, nut butters, nuts, grains, proteins. Visual estimation of these foods produces consistent undertracking.

Step six: monitor weekly weight averages rather than daily readings. Weight fluctuates daily due to water, sodium, hormones, and food volume. Weekly averages over 2-4 weeks show the actual trend. React to trends, not single data points.

Step seven: recalculate your TDEE every 10-15 pounds of weight loss. Your maintenance calories drop as body weight drops.

The research from the National Institutes of Health, the Academy of Nutrition and Dietetics, the American Council on Exercise, and Harvard T.H. Chan School of Public Health all point to the same practical conclusion: a moderate, consistent calorie deficit paired with adequate protein and an honest activity assessment produces reliable, sustainable fat loss. This beginner guide to calorie math gives you the exact tools to do that, starting today.
