The Low-Density Hunger Buffer combines nutritional sequencing with mindful eating and a simple appetite-management tool. Gethin first suggests essential amino acids to provide some nutritional support and help prevent a sharp blood-sugar drop. At the next meal, maximize physical volume with vegetables, salad, and optional fruit while limiting calorie density, and eat that fiber-rich portion first. Then slow the meal down: remove distractions, engage the senses, appreciate the food, and put the fork down between bites. This shifts eating away from a rushed, distracted state and can increase fulfillment. If hunger remains, particularly before bed, use a carbonated drink such as carbonated water with electrolytes to create fullness and interrupt the urge to keep eating.
Origin
Gethin assembled these tactics in response to Jennifer Cohen's question about balancing cardio's mental benefits against the hunger it can create.
Core principles
- 01Feed recovery before hunger becomes extreme
- 02Maximize food volume without maximizing calorie density
- 03Eat high-fiber foods before denser foods
- 04Attention and sensory contact improve meal satisfaction
- 05Carbonation can help take the edge off hunger
How to run it
- 1
Buffer the drop
Use essential amino acids around cardio if they fit the person's nutrition plan. The aim is to provide support before post-cardio hunger escalates.
Watch out Do not mistake nutritional support for a filling meal.
- 2
Lead with volume
Fill the first part of the meal with vegetables, salad, and optional fruit. Eat these high-volume, lower-density foods before denser foods.
Pro tip Mix several textures and foods so the meal still feels varied.
- 3
Slow the meal
Remove the phone, engage the senses, and put the fork down between bites. Give the meal enough attention for satisfaction to register.
Pro tip Briefly consider where the food came from to replace resentment about a repetitive diet with gratitude.
Watch out Distracted eating makes it easier to wolf down food without feeling fulfilled.

Close with carbonation
If residual hunger remains, use carbonated water, optionally with electrolytes, to add a sense of fullness and create a pause.
Pro tip This can be especially useful for late-evening hunger.
Watch out Use it as a buffer, not a replacement for necessary food.
In the wild
Gethin describes going to bed very hungry and using a carbonated drink, such as carbonated water with electrolytes, to feel fuller and make sleep easier without adding a dense meal.
→ The carbonation takes the edge off the immediate urge to eat.
Common mistakes
Starting with calorie-dense food
Skipping the high-volume first course makes it easier to consume more calories before fullness develops.
Eating while scrolling
Distraction reduces sensory contact with the meal and can leave the person less fulfilled.
Using carbonation instead of nutrition
Carbonation can interrupt a craving, but it should not conceal a genuine need for adequate food.
Is it for you?
Best for
It is best for active people who become ravenous after cardio or struggle with hunger while dieting.
Not ideal for
It is not ideal as a substitute for adequate nutrition, medical evaluation, or treatment of persistent disordered eating.
From the transcript
“So, it could be your vegetables, it could be your salad, you could throw, you know, some fruits in there if you want. mix it…”
“But make sure that you're putting a fork down between bites. Uh you're not distracted. You're not scrolling on your phone.”
“I'll usually have like a carbonated drink. You know, that could be carbonated water with electrolytes.”
