How to maintain a healthy lifestyle for a long time without relying on sugar
For decades, sports nutrition has been based on a simple idea:
More carbohydrates = more performance.
This approach may work… for a minority of elite athletes competing at very high intensity.
But for the vast majority of endurance athletes, it primarily creates:
– glycemic fluctuations
– digestive problems
– an addiction to sugar intake
At Brutal Salty Energy (BSE) , we advocate a different approach:
reduce sugars, restore the ability to burn fat, and regain stable energy.
Energy and metabolism: what science actually says
The human body has two main fuels for producing ATP (cellular energy):
– carbohydrates
– lipids
The choice of fuel depends primarily on:
– the intensity of the effort
– its duration
– the athlete's metabolic state
The work of Phinney and Volek showed that trained athletes adapted to a low-carbohydrate diet can oxidize up to 1.5 to 1.85 g of lipids per minute , including at moderate to high intensities.
This represents a more than sufficient amount of energy to support prolonged endurance efforts, without relying on a constant supply of sugar .
Why reducing sugars often improves performance
Carbohydrates are a quick source of energy, but:
– their reserves
– their use is highly dependent on insulin
– their excess blocks the oxidation of fats
When an athlete regularly consumes sugars during exercise:
– blood sugar rises then falls
– Insulin inhibits lipolysis
– metabolism becomes dependent on external inputs
This mechanism explains why:
– You need to reapply the gel every 40–45 minutes
– the cessation of supplies causes a “wall”
– Digestive problems appear during prolonged exertion
Conversely, reducing sugars helps to reactivate the use of lipids , a source:
- stable
– abundant
– virtually unlimited
Ketosis, low-carb diets, and metabolic adaptation
When carbohydrate intake is drastically reduced over time, the body adapts.
It increases:
– the production of ketone bodies
– mitochondrial capacity
– the oxidation of fats
This process, described as early as the 1980s by Phinney, is now widely documented in endurance athletes.
After an adaptation phase (2 to 3 weeks on average), the athlete becomes:
– less sensitive to glycemic fluctuations
– more energy stable
– less dependent on sugary snacks
Tim Noakes has largely contributed to popularizing this approach in endurance sports, showing that performance does not depend solely on carbohydrates, but on metabolic flexibility .
Carbohydrates vs. lipids: a functional comparison
A typical energy gel contains on average:
– 65 to 75% carbohydrates
– very little fat
– a low energy density (~90 kcal per 30 g)
It provides a quick, but short-lived, burst of energy at the price of:
– from digestive stress
– metabolic instability
Conversely, a predominantly lipid-based energy source:
– provides more calories per gram
– does not cause a blood sugar spike
– supports the effort over the long term
👉 The goal is not to eliminate carbohydrates completely, but to put them back in their proper place : an occasional tool, not a permanent crutch.
And what about sport in all of this?
For most endurance sports:
– the intensity is mostly in Zone 2
– the lipid contribution is dominant
– the limitation often comes from hydration, sodium, and digestion, not sugar
Even without being strictly "keto-adapted," reducing sugars during training allows you to:
– to improve fat oxidation
– to limit digestive problems
– to build a more robust metabolic engine
Carbohydrates can still be useful:
– on the end of an effort
– during very high intensities
– in targeted competition
But they should no longer be the basis of every outing.
The Brutal Salty Energy approach
At BSE , our products are designed to:
– to provide a stable, predominantly lipid-based energy source
– limit unnecessary sugars
– to support real endurance, not theoretical endurance
– to preserve digestion and metabolic health
They are part of a modern performance strategy:
Fewer peaks, more consistency, more freedom.
In summary
– The majority of athletes do not need much sugar
Reducing carbohydrates often improves digestive stability and tolerance
– Lipids are a powerful and underutilized fuel
– The key is not extremes, but metabolic coherence
Less sugar.
More control.
Lasting endurance.
That's it, Brutal Salty Energy.
