The secret to a better memory is not cramming more in — it is learning to care about what you want to keep.

Quick Take

Memory expert Dr. Charan Ranganath says the goal should be to remember better, not more — and five simple techniques can get you there fast.
Even a 10-minute walk can improve memory and retention, making exercise one of the easiest brain upgrades available.
A 12-week lifestyle program showed a 1-3% increase in hippocampal volume, proving the brain can physically grow back with the right habits.
Deepfake scam ads using Dr. Sanjay Gupta’s face have racked up 35 million views pushing fake memory cures — knowing the real techniques protects you from both.

Your Brain Was Never Built to Remember Everything

Most people treat forgetting like a personal failure. It is not. Dr. Charan Ranganath, a memory researcher, puts it plainly: stop trying to remember more and start trying to remember better. ^[1] That shift in thinking changes everything. Your brain does not work like a hard drive. It works like a filter — keeping what matters and dumping what does not. The trick is telling it what matters.

Ranganath lays out five techniques that work with how the brain filters. First, connect new information to something you already care about. Second, test yourself instead of just re-reading. Third, make the information stand out — weird, funny, or surprising details stick. Fourth, attach emotion to what you want to keep. Fifth, use your senses to build a richer mental picture. ^[1] These are not tricks. They are how memory actually works at the biological level.

Memory Champion Tricks That Anyone Can Use Today

Nelson Dellis is a four-time United States Memory Champion. He uses two methods that sound almost too simple. The first is chunking — breaking a long sequence into smaller, meaningful groups. The second is story visualization — turning dry information into a vivid mental movie. ^[2] Dellis demonstrated memorizing the alphabet backwards by linking letters to beach imagery. The story does the heavy lifting so your brain does not have to strain. He also recommends the Pomodoro technique: 25 minutes of focused practice, then a 5-minute break. Short bursts beat long slogs every time.

Self-testing is the most underrated tool on the list. Most people review notes passively. That feels comfortable but teaches the brain almost nothing. Forcing yourself to recall something — even when you get it wrong — builds stronger memory pathways than reading the same page four times. Trial and error is not failure. It is the actual training. ^[2]

Your Brain Can Physically Grow Bigger at Any Age

Here is the part most people do not know. Cognitive decline is not a locked-in fate. Dr. Majid Fotuhi published a study in the Journal of Prevention of Alzheimer’s Disease showing participants in a 12-week multimodal program gained 1-3% in hippocampal volume — the brain region most critical to memory. ^[6] That is measurable, physical brain growth in adults. The program combined exercise, sleep improvement, nutrition, stress reduction, and brain training. Five pillars. All of them within reach of ordinary people without a prescription.

Fotuhi also points out that obesity, chronic stress, sleep apnea, depression, and concussions each cause measurable hippocampal shrinkage — but the damage is reversible. ^[6] That is a powerful and hopeful finding. Current Alzheimer’s drugs that target amyloid plaques clear the plaques but do not restore function. Lifestyle changes, by contrast, actually rebuild the brain’s hardware. The research funding priorities do not yet reflect that reality, but the science does.

A 10-Minute Walk Beats Most Brain Supplements on the Market

Physical activity is one of the fastest and cheapest brain upgrades available. Even a 10-minute walk improves memory and retention. ^[3] That is not a motivational slogan — it is a measurable effect on brain chemistry. Exercise increases blood flow to the hippocampus, triggers the release of brain-derived neurotrophic factor, and reduces the stress hormones that actively damage memory. The supplement industry will not tell you that, because they cannot sell you a walk.

Deepfake Scams Are Poisoning the Well of Real Brain Health Advice

Dr. Sanjay Gupta discovered his face and voice had been cloned by artificial intelligence to sell fake memory supplements. Those deepfake ads reached 35 million views. ^[2] Some of the scam videos offered multiple bottles of unproven pills for hundreds of dollars — with no delivery. The fraud works because people are desperate for real answers about memory loss. The scammers exploit that fear with absolute promises no legitimate doctor would ever make. Gupta’s response was to go public and teach people what real memory science actually looks like. That is the right move — and the contrast between his approach and the scammers’ tells you everything about who to trust.
