This Week's Train Your Brain Game
The Semantic Sprint: How Fast Can Your Brain Find the Words?
Before You Play
This game is built from a Habit Healers article. You need to read it first. The article will prime your brain with vocabulary, concepts, and connections that make every round richer and faster. Without it, you are running on fumes.
Read the full article here: “Why Are the Fast Eaters Three Times More Likely to Carry Belly Fat?”
Then come back and play.
Why This Game Trains Your Brain
Verbal fluency, the ability to rapidly generate words from a category, is one of the earliest cognitive abilities to show age-related change. Clinicians use timed word-generation tasks as a standard assessment of frontal-temporal brain function because the task requires your brain to do two things at once: search your semantic networks for qualifying words while simultaneously suppressing words you have already said or that do not fit the rule. This game adds a layer the clinical version does not have. By tying every category to an article you just read, it forces your brain to activate recently formed semantic connections alongside long-established ones. That blend of new and old is where the training value lives. Round 2 adds set-shifting demands (alternating between categories), and Round 3 engages creative problem-solving through spreading activation in your semantic networks.
ROUND 1: CATEGORY FLOOD
Set a timer for 60 seconds per category. Write down as many words as you can that fit. No repeats. Proper nouns count if they appeared in the article.
Category A: FULLNESS AND HUNGER
List as many words as you can related to the sensations, signals, or experiences of feeling full, feeling hungry, or having your appetite change. Think about what you learned from the article about how the body communicates these states.
Scoring: Beginner (8+), Sharp (15+), Elite (22+)
Category B: THE SCIENCE OF EATING
List as many words as you can related to the scientific study of how, when, and why humans eat. Include hormones, body parts, research terms, and biological processes discussed in the article.
Scoring: Beginner (8+), Sharp (15+), Elite (22+)
Category C: THINGS THAT CHANGE WHEN YOU SLOW DOWN
List as many words as you can for outcomes, effects, or experiences that change when a person eats more slowly, based on what the article described.
Scoring: Beginner (6+), Sharp (12+), Elite (18+)
ROUND 2: ALTERNATING CATEGORIES (90 seconds)
This is where it gets uncomfortable. Set a timer for 90 seconds.
Alternate back and forth between these two categories, naming one item from each before moving to the next pair:
Category 1: A HORMONE OR BIOLOGICAL SIGNAL discussed in the article
Category 2: A SPECIFIC STUDY OR EXPERIMENT described in the article (identify it by any distinguishing detail: the food used, the number of participants, the country, the device, etc.)
Example: “GLP-1... the gum-chewing study... CCK...” and so on, alternating.
The difficulty is not in recalling the items. The difficulty is in switching between two completely different types of information while keeping your place in both lists. That switching cost is the workout.
ROUND 3: REMOTE ASSOCIATES (untimed)
Each puzzle below gives you three words. Your job is to find a single word that forms a common phrase, compound word, or strong association with ALL three. Every puzzle connects to vocabulary or concepts from the article.
Take your time. The “aha” moment when the linking word clicks into place is your semantic network firing across distant nodes.
Puzzle 1: eating ... food ... forward
Puzzle 2: cream ... age ... breaker
Puzzle 3: pressure ... sugar ... stream
Puzzle 4: loss ... gain ... lifting
Puzzle 5: down ... over ... away

ANSWER KEY
ROUND 1: Sample Words (not exhaustive)
Category A (Fullness and Hunger): satiety, appetite, fullness, hunger, craving, satisfaction, overstuffed, bloated, famished, starving, peckish, ravenous, stuffed, nausea, discomfort, signal, suppression, desire, urge, second helpings, empty, growling, GLP-1, CCK, PYY, ghrelin, hypothalamus, gut hormones, belt-loosening, portions, “enough”
Category B (The Science of Eating): GLP-1, CCK, PYY, ghrelin, hypothalamus, intestine, gut, hormones, satiety, metabolism, metabolic syndrome, BMI, cholesterol, blood sugar, blood pressure, calories, chewing, mastication, digestion, enzymes, absorption, gastric emptying, participants, control group, meta-analysis, observational, crossover, longitudinal, waist circumference, insulin
Category C (Things That Change When You Slow Down): hormone levels, PYY increases, GLP-1 increases, calorie intake decreases, fullness sensation, portion size, hunger fades mid-meal, ghrelin drops, BMI, waist circumference, weight, metabolic risk markers, blood sugar, blood pressure, belly fat, conversations, stress level, awareness of food, breathing, meal duration, desire for seconds
ROUND 2: Items You Could Have Named
Hormones/Biological Signals from the article: GLP-1, CCK (cholecystokinin), PYY (peptide YY), ghrelin, satiety signal, hypothalamus signaling, neural pathways from chewing
Studies/Experiments from the article: the gum-chewing study (12 men, sugarless gum, 30 minutes), the 40-chew vs. 15-chew study, the ice cream experiment (17 volunteers, 675 calories, 5 vs. 30 minutes), the large meta-analysis (29 studies, 465,000+ people), the Japanese longitudinal study (nearly 60,000 adults, 6 years), the dental splint experiment (6 men, custom appliance on molars), the 12-meal controlled feeding study (30 participants, texture-engineered meals), the chewing-and-appetite systematic review
If you named 4+ hormones and 4+ studies while alternating smoothly, you performed at an elite level.
ROUND 3: Remote Associates Answers
Puzzle 1: FAST (fast eating, fast food, fast forward). The article’s central subject is the consequences of fast eating.
Puzzle 2: ICE (ice cream, ice age, icebreaker). The ice cream experiment, where 17 volunteers ate 675 calories of ice cream at two different speeds, is one of the article’s key studies.
Puzzle 3: BLOOD (blood pressure, blood sugar, bloodstream). The article discusses how satiety hormones build up in the bloodstream, how fast eating raises blood pressure and blood sugar risk, and how metabolic syndrome markers include abnormal blood values.
Puzzle 4: WEIGHT (weight loss, weight gain, weightlifting). The dental splint study produced a median weight loss of 11% of initial body weight, and the population data consistently links eating speed to higher body weight.
Puzzle 5: BREAK (breakdown, break over, breakaway). The article describes putting the fork down between bites, breaking the autopilot habit. The dental splint study also explored what happens after the constraint breaks off.
Want to go deeper? Re-read the article tomorrow and try Round 1 again. Count how many more words you generate on the second attempt. That increase is your semantic network expanding in real time.
