If your goal is fat loss, muscle building, or body recomposition, you are going to run into the “net carbs vs total carbs” conversation pretty quickly. Food labels brag about “only 3 grams net carbs,” influencers tell you to subtract fiber, and low-carb communities treat net carbs like a secret code for better fat loss and better blood sugar control. The math is always the same: take total carbs, subtract fiber (and sometimes sugar alcohols), and what is left is supposed to be what “really counts.”

That idea grew out of blood-sugar management and keto dieting, where the main concern is how much a food spikes glucose. It is not completely useless in that narrow context, but when the real goal is changing how your body looks and performs - losing fat, managing weight, building muscle, and potentially stepping on stage - the net carb game does not actually give you anything extra for the effort.

For people focused on physique and performance, whether you are a lifestyle client, in an off-season build, or a competitor, total carbs are a cleaner and more useful tool. Total carbs simply means the number on the Total Carbohydrate line of the label, fiber included. That is the approach we use with our own clients, and there are simple, practical reasons behind it.

Why Fiber Confuses So Many Dieters

A lot of the confusion starts with how fiber gets talked about. People hear that fiber does not raise blood sugar the same way sugar and starch do, and the takeaway becomes, “fiber doesn’t count.” That is not how your body sees it.

Certain types of fiber are fermented in the gut and turned into short-chain fatty acids, which are then absorbed and used for energy. Think of it like a slow-drip fuel source instead of a fast sugar rush. It is not the same as drinking a soda, but it is not zero either. That is why many nutrition researchers assign fiber a small but real calorie value instead of treating it like air.

You do not need to obsess over the exact number, but it matters when you subtract all your fiber and call what is left your “real carbs.” At that point, you are underestimating what you actually take in, which can quietly throw off a precise fat loss or muscle building plan, the same way a “little” overspending adds up in a monthly budget.

How Evidence-Based Physique Coaches Handle Carbs

Coaches who live in the evidence-based physique world have quietly solved this in a very simple way: they count fiber inside the carb number and move on.

Eric Helms, PhD supports total carbs over net carbs. In his nutrition templates, for example, list a carb target and a suggested fiber range, and make it clear that fiber is included in that carb target. If the sheet says 300 grams of carbs with 30–40 grams of fiber, that fiber lives inside the 300, not added on top and not subtracted out. Layne Norton, Cliff Wilson, and others take a similar practical stance.

Layne goes on to say in his book The Complete Contest Prep Guide that, "it’s best to track fiber as a carbohydrate. Don’t worry about ‘net carbs’ in relation to ‘total carbs.’ You’ll go crazy trying to separate the two…” While in Bodybuilding: The Complete Contest Preparation Handbook by Cliff Wilson and Peter Fitschen, PhD, its clearly states, "to avoid confusion, count fiber along with other carbohydrates consumed and aim to have a consistently high fiber intake."

The goal is not to be dogmatic. It is to have numbers that actually mean something when you look back at what worked. When total carbs always mean “what is on the label,” you can compare phases, progress, and preps without trying to decode your own diary.

‍

“If Adjustments Fix It Anyway, Does It Really Matter?”

A fair question is whether any of this matters if adjustments are always based on progress. If you stay consistent with some method of tracking, the coaching process will “auto-correct” over time. Eating too much leads to slower fat loss, so macros or activity are adjusted. Eating too little leads to faster loss or poor performance, so food is added back in.

That feedback loop works whether you track total carbs, net carbs, or invent your own color-coded system. Your body responds to real energy in and real energy out, not to what the app column is called.

Where it becomes relevant is how clean and useful your starting point is.

Why Net Carbs Create “Noise” In Your Plan

Imagine a coach sets an athlete at 130 grams of carbs. If that athlete decides on their own that means “130 grams net,” their actual intake might look like 170 grams total with 40 grams of fiber. On their log, it says “130.” In reality, their intake is closer to 170 total carbs, loaded with high-fiber products and “low-carb” foods.

Now the line between what was prescribed and what the body is experiencing starts to blur. The coach thinks they are seeing the impact of 130 grams. The body is living on 170. Progress-based adjustments will still bring the plan back on track, but:

• There is extra math.
• There is more room for interpretation.
• There is less clarity about what “130 grams” really did for that person.

Over months of dieting or building, that noise adds up. In a lifestyle fat loss phase, it might mean slower progress at an intake that seems moderate on paper, which leads to more aggressive cuts than were actually necessary. In an off-season, it can mean drifting into a higher surplus than intended and carrying more fat than needed into the next phase.

In contest prep, with a hard date on the calendar, that extra layer of fuzziness is exactly what makes people feel like their body “doesn’t respond,” when in reality the inputs were never as consistent as they looked in the app. It is like following a GPS that reads miles while the map is secretly in kilometers.

‍

The Practical Advantage Of Total Carbs

There is also the practical side: total carbs are simple. Every nutrition label has a Total Carbohydrate line. You can look at that number, track it, and be done.

Net carbs require subtracting fiber, and sometimes sugar alcohols, on every high-fiber food. Then you have to remember that your logs are now in a different “language” than most plans, calculators, and research use.

For someone already juggling work, family, training, sleep, digestion, stress, and, for competitors, posing and show dates, that extra layer of arithmetic is rarely a good trade. Keeping things simple often makes it easier to be consistent, and consistency is where body recomposition and long-term fat loss actually happen.

‍

Repeatability: Learning From Your Own Data

Repeatability is another big reason we favor total carbs. One of the major advantages of logging food over time is the ability to look back and answer questions like:

• At what intake did you feel strong and recover well?
• Where did you maintain comfortably without feeling deprived?
• At what carb range did you stay relatively lean in the off-season so the next cut was not a nightmare?

Those questions are easier to answer when “200 grams of carbs” has meant roughly the same thing every time. If half of your history is logged as total carbs and the other half as net carbs, or if fiber quietly increased while being subtracted out on paper, it becomes much harder to pull clear lessons from your own data.

Think of it as keeping training logs where sometimes you count only “working reps” and other times you count every rep, warm-ups included. Looking back, it is tough to compare phases and know what truly worked best.

‍

What This Looks Like In Real Life

So what does this look like in practice for someone trying to manage weight and build muscle, whether you ever work with a coach or not? A sensible approach is:

• Pick a calorie and macro structure.
• Treat the carb target as total carbs from the label, fiber included.
• Keep fiber in a healthy range from mostly whole food sources.
• Do not treat fiber as a free pass to add more carbs on top.

Track intake as honestly as possible, then adjust based on results:

• Weight trends
• How clothes fit
• Training performance
• Energy levels
• And for competitors, how your body actually looks in progress photos and on stage

That is exactly how we handle it with our clients. The numbers we use are total carbs, not net. Fiber lives inside those numbers. Progress over time tells us whether the plan needs more or less food, not clever label math. Net carbs do not create extra clarity for us as coaches; they create extra work and more noise for the person doing the tracking.

The Bottom Line: Keep It Simple And Let Consistency Win

Net carbs are an interesting concept that grew out of a different context. For most people focused on body composition, whether your goal is losing fat, staying leaner in the off-season, or bringing your best look to the stage, there is no real advantage over using total carbs.

What drives results is:

• Consistency
• Honest tracking
• Smart, data-driven adjustments

Keeping the method simple, sticking with total carbs, and letting your real-world progress guide the tweaks is usually the fastest path to a better physique, whether you are doing it on your own or working with a coach who lives in this world every day.
