Healthy Eating For Productivity

Not drinking enough water can shrink your brain and slow it down by 20%. Even mild dehydration (just 1–2% fluid loss) can: -Shrink brain tissue (visible in MRI scans) -Make you process information slower -Reduce your focus and memory recall -Trigger mood swings and mental fatigue -Increase cortisol (your stress hormone) In one experiment, dehydrated participants had 20% slower reaction times and made twice as many mistakes on cognitive tests. And MRI scans backed this up: Even slight dehydration causes your brain to contract - similar to what happens with 1 year of aging. Rehydration reverses it, but the impact on productivity and mood is immediate. As a doctor, this didn’t surprise me. Your brain is 75% water. And yet, most people don’t drink enough - especially in AC offices. The problem is: Thirst isn’t a reliable signal. By the time you feel thirsty, you may already be underperforming. That’s why I recommend a few simple habits: ▶︎ Start your morning with a full glass of water - ideally before caffeine. ▶︎ Keep a bottle within reach - visual cues help you drink consistently. ▶︎ Aim for 3L- 4L a day - and more if you’re sweating, outdoors, or travelling. And if you’ve been feeling foggy or unmotivated lately? Don’t jump straight to burnout or overwork. Sometimes, it’s just dehydration. Repost this to help someone snap out of that brain fog. #healthandwellness #heathtips #workplacehealth

Whole new fields of research such as nutritional psychiatry have emerged since I wrote The UltraMind Solution about how the body affects the mind in 2009. Stanford has a department of Metabolic Psychiatry. Harvard now has a department of Nutritional Psychiatry. Studies show that simply swapping out processed, sugary starchy foods for whole foods is effective in treating depression. ⁣ ⁣ Studies also show kids with severe violent behavior transform when swapping out processed foods for whole foods, including a 75% reduction in the use of restraints and a 100% reduction in suicides, which is the 3rd leading cause of death in that age group. ⁣ ⁣ One study of violent juveniles found that simply giving children a vitamin and mineral supplement reduced violent acts by 91 percent compared to a control group. Why were they violent? ⁣ ⁣ Their brains were starving for nutrients that regulate mood and behavior including iron, magnesium, B12, and folate. Just giving these kids vitamins for three months fixed their abnormal brain waves on EEG. The kids who also changed their diet had an 80% reduction in violent crime and those who stayed on a processed diet continued their violent ways.⁣ ⁣ While many children are not eating enough brain food, they are also eating too many chemicals, including about five pounds of dyes, preservatives and additives that are linked to hyperactivity and worse.⁣ ⁣ While therapy, stress reduction, and movement are equally critical in many brain disorders, food plays a pivotal and often overlooked role. ⁣ ⁣ Start small. Start with the Pegan Diet. Eat loads of veggies, some fruit (especially the low-sugar, nutrient-dense ones), whole grains (not flours), nuts and seeds, low-starch beans and legumes, and some high-quality meat, poultry, and fish. Focus on brain foods that have been shown to impact mood and reduce symptoms of depression and anxiety— foods rich in omega-3s, zinc, magnesium, vitamin D, antioxidants, and B vitamins.

A recent study published in Annals of Neurology (PMID: 39927551) reveals that low levels of active Vitamin B12 (holotranscobalamin) are linked to reduced white matter integrity and poorer cognitive performance, while total B12 levels may not accurately reflect brain health. Vitamin B12 is crucial for maintaining nerve function, brain health, and DNA synthesis. It exists in two forms: - Active B12 (Holotranscobalamin): The bioavailable form directly utilized by cells. - Inactive B12 (Haptocorrin-bound): Circulates in the bloodstream but is not available for cellular functions. Traditional blood tests measure total B12, which includes both active and inactive forms, potentially masking deficiencies that could impact cognitive function. Findings: - Participants with low active B12 showed significant white matter breakdown and impaired cognitive function compared to those with adequate levels. - The study demonstrates the importance of measuring active B12 for accurate brain health assessment. This study highlights the need for a paradigm shift in Vitamin B12 testing and supplementation, emphasizing active B12 as a critical biomarker for brain health and cognitive function. In the United States, Vitamin B12 deficiency is defined as a blood level below 148 pmol/L. The American Society for Nutrition criticized this approach, highlighting that over 5% of patients with symptoms of B12 deficiency and who respond to B12 supplementation have blood levels above this threshold. Studies suggest that B-vitamin supplementation benefits individuals with clinical signs of deficiency, regardless of their measured blood levels.

🕐 When You Eat May Be Just As Important As What You Eat New research in Gastroenterology is revolutionizing how we understand digestive health with major implications for our 24/7 society. 🧬 THE SCIENCE: Your Gut Has Its Own Clock Your intestinal tract operates on molecular clocks that regulate: • 🔄 Nutrient absorption and metabolism • 🛡️ Intestinal barrier integrity • 🦠 Microbiome composition • ⚔️ Immune function • 💊 Medication responses These clocks evolved to sync with natural light-dark cycles. Modern life? Throwing everything off balance. ⚠️ THE PROBLEM: Living Against Our Biology • 🌙 Shift work (15-30% of workers) • 📱 Light pollution and late-night screens • 🍕 Eating within 3 hours of sleep • 😴 Social jet lag (affects ~80% of people!) 📊 THE CONSEQUENCES 🔴 IBD patients with evening chronotypes have more severe disease 🔴 Rotating shift nurses: 48% IBS prevalence vs. 31% in day workers 🔴 Night shift work: 27% increased pancreatic cancer risk 🔴 Late eating damages gut barrier proteins, causing "leaky gut" 🔴 Circadian disruption reduces beneficial bacteria 💡 THE SOLUTIONS ⏰ Time-Restricted Feeding Eat within 8-12 hours during daylight. Improves insulin sensitivity and gut health even without calorie reduction. 💊 Chronotherapy Timing medications matters: PPIs work best in the morning; immunotherapy shows better cancer outcomes when given in morning. ☀️ Bright Light Therapy Morning light exposure resets your master clock and improves IBD quality of life. 🎯 THE TAKEAWAY Eating at 11 PM isn't just adding calories—you're confusing thousands of genes involved in digestion, immunity, and metabolism. Simple changes with profound impacts: ✅ Finish dinner 3+ hours before bed ✅ Eat breakfast within 1-2 hours of waking ✅ Get morning sunlight ✅ Keep consistent sleep schedules The future of medicine is about WHEN we eat and treat, not just WHAT. 💭 Have you noticed how meal timing affects your digestion or energy?

A Healthy Workforce is a Healthy Business... Over the years, first at The Bear Kitchen and now at The Pulse Kitchen, we have collaborated with progressive employers to make their workforces healthier by integrating more pulses and plants into workplace meals. Research indicates that people consume at least a third of their daily calories at work. What we eat and drink affects our health and work performance. When employees don't maintain a balanced diet or stay hydrated, they can experience headaches, sluggishness, and difficulty concentrating, all of which can hamper productivity. Harvard studies have shown that companies with impactful health and food strategies at work outperform others over time. They achieve longevity in their workforce, which translates to sustained business success. Our Philosophy: We have developed and refined our “Eat Like A Bear Framework,” combining it with behavioural change interventions and ensuring our food is irresistibly tasty to help employers and food service operators shift employee behaviour towards more plant-rich meals. When you get the food offer right, and people eat like a BEAR every week, you see: 🚀 Increased productivity ❤️ Lower absenteeism 🧠 Improved talent acquisition and retention 🌱 Significant reduction in meat consumption While some of these benefits are hard to measure directly, consider the value of: 💡 People coming to work energised and happy 💡 Employees engaging positively with customers 💡 Better work performance due to improved focus and energy Healthy and tasty food is one of the most impactful ways to boost health and productivity in a workplace. Food initiatives must be part of a broader health and well-being strategy to maximise their impact. Our Experience: Over the years, we've learned that any food, health, or wellbeing programme must be built into the very DNA of a company. It needs to be aligned with the company’s culture and business goals. Leadership commitment is crucial; leaders must walk the talk and integrate these values deeply into the organisational ethos. For a company to perform well, it needs healthy people. The fewer healthy people you have, the worse your business will perform. ❓Reflect: What are you doing with food to improve the longevity and health of your people? DM me for a conversation on how we can PULSE POWER your workforce! #health #foodservice #workplace

Working across regional development and nutritional therapy it might not come as a surprise that I’ve been thinking a lot lately about the biology of productivity. In March, a new business coalition was formed to ‘tackle poor UK productivity.’ There is no doubt that they will consider levers such as the adoption of tech, skills and training, infrastructure, and regulation. But will they think about individual performance? But will they consider a possible correlation between plummeting productivity and the rise in physical and mental ill health? The average number of paid sick days rose 20% (to 5.7) between 2021 and 2022 with the average absence period increasing by 15%. Whether related to COVID-19 or not, this creates an opportunity to consider what could positively affect the biology of productivity. Here’s a starter for ten - what would you add? 🐟 Eat more oily fish and good fats (olive oil, nuts, seeds, etc) to improve brain performance and reduce chances of getting certain illnesses. Higher Omega 3 levels have been shown to decrease the likelihood of catching Covid-19. 🥒 Consume as many vegetables, herbs, and spices as you can manage. These are full of plant chemicals that help optimise how your body works. ☕ Don’t drink coffee after midday - this will help improve your sleep (1/4 of the caffeine is still in your bloodstream 12 hours later). ⏰ Introduce a regular bedtime and waketime. The routine helps your circadian rhythm, helps increase energy, and lowers your risk of illness. As an employer, let me know if you’re interested in bringing some of these research-based insights (and more) to your team. #wellbeing #health #productivity #efficiency #culture

𝗠𝗼𝘀𝘁 𝗲𝘅𝗲𝗰𝘂𝘁𝗶𝘃𝗲𝘀 𝘁𝗵𝗶𝗻𝗸 𝗽𝗿𝗼𝘁𝗲𝗶𝗻 𝗶𝘀 𝗽𝗿𝗼𝘁𝗲𝗶𝗻. They're wrong. And it's destroying their afternoon performance. I spent the time analyzing the latest protein research, and what I discovered will change how you think about your daily nutrition strategy. Here's the reality: That expensive protein bar between meetings? It's likely incomplete. Your post-workout shake? Missing critical absorption windows. Your lunch chicken? Poorly timed. The result? Energy crashes at 3 PM. Mental fog during critical decisions. Slower recovery when you need it most. But here's what peak performers actually know: → Amino acid profiles matter more than total protein content → Timing beats quantity every single time → Your body has a processing limit that most people ignore → Plant-based combinations can outperform animal sources The research is clear: optimized protein timing boosts cognitive function by 15% and eliminates afternoon energy crashes by 40%. Watch my latest video. No fluff, just actionable science. Question for you: What's your current protein strategy? Most successful people I know have completely rethought their approach.

Your meals are software updates. But here’s the catch: not all updates improve performance. Some install faster processing, sharper focus, and clean energy. Others slow you down, drain your battery, and crash the system. Take this: 500 calories from salmon and greens vs 500 from pizza. Same energy on paper. Completely different code in reality. Food isn’t just fuel. It’s information. Every bite sends instructions to your metabolism, hormones, and brain. Get it right and you avoid the dreaded afternoon slump. Get it wrong and you’re battling brain fog at 2pm when your team needs you firing. 🤓 Science backs this up. Studies show diets higher in whole foods and omega-3 fats improve cognitive function and mood regulation, while processed foods increase fatigue and stress. 💡Thrive Tip: Keep a simple “Food Feedback Loop.” After each meal, ask: Energised or flat? Clear or foggy? Satisfied or craving more? Do this for a week and you’ll spot the patterns. You’ll know exactly which foods upgrade your operating system and which corrupt it. Because real health isn’t about eating less. It’s about installing the right code.

High-performing professionals obsess over productivity hacks. But they're overlooking a simple factor that impacts every critical decision: Meal Timing. A recent UCSD study caught my attention. Adults with metabolic syndrome who ate within an 8-10 hour window (without changing their diet) saw significant improvements in blood sugar, HbA1c, and cholesterol after 12 weeks (Annals of Internal Medicine). But here's what struck me: Participants also reported better mental endurance. Translation? Your 3 PM decision-making clarity depends on your breakfast timing. . Late eating creates: ➡️ Glucose spikes ➡️ Cortisol elevation ➡️ Decision fatigue and brain fog. For busy professionals making critical choices under pressure, this metabolic chaos is career limiting. Here’s how to reclaim focus and energy: ✔️ Define your eating window - Mine is 7 AM to 5 PM. Find what fits your schedule and stick to it consistently. ✔️ Front-load protein - Starting with 25-30g protein sets stable energy for the day. Think eggs, Greek yogurt, or a quality protein shake. ✔️ Close the kitchen early - Stop eating 2-3 hours before bed. Your body repairs better when it's not digesting. ✔️ Track what matters - I use glucose monitoring to understand how different foods and timing affect my energy levels. The Payoff? More consistent energy, clearer thinking during afternoon meetings, and better sleep quality. This isn't about perfection, it's about creating sustainable patterns that support both performance and well-being. What eating patterns have you noticed impact your decision-making?

4 Simple Nutrition Hacks That Keep Me Consistent (Even with a Packed Schedule) As a busy professional, my days are a whirlwind—back-to-back meetings, travel, and the constant juggle of work and family. A few years ago, I was drained, grabbing takeout or skipping meals, and feeling the weight of stress piling up. I knew I needed to prioritize nutrition to fuel my energy and leadership, but the idea of complex meal plans or hours in the kitchen felt impossible. That’s when I discovered the power of simplicity in nutrition—and it’s been a game-changer for staying consistent, even with my chaotic lifestyle. Here’s what I do to keep it simple: 1. The 80/20 Rule: I focus on eating whole, nutrient-dense foods 80% of the time—think lean proteins, veggies, and healthy fats. The other 20%? I enjoy my favorite treats, like a slice of pizza or dark chocolate, guilt-free. This balance keeps me satisfied without feeling deprived. Research shows that flexible eating approaches like this lead to 95% better adherence compared to restrictive diets. 2. The One-Plate Formula: I don’t overthink meals. My go-to is a single plate: half veggies, a quarter protein (like grilled chicken or salmon), and a quarter complex carbs (like quinoa or sweet potato). It takes 5 minutes to plan and ensures I’m getting balanced nutrition. Studies link balanced macronutrient intake to a 30% reduction in stress hormones like cortisol, which is critical for high performers like us. 3. Batch Prep for the Win: On Sundays, I spend 30 minutes prepping staples—chopping veggies, grilling protein, or making a big batch of overnight oats. This means I have grab-and-go options all week, saving me from decision fatigue. Data shows that meal prepping can save up to 7 hours a week, giving me time for what matters most. 4. Hydration as a Non-Negotiable: I carry a water bottle everywhere and aim for 80 ounces a day. Staying hydrated keeps my energy up and my mind sharp, especially during long meetings. Research indicates that even mild dehydration can increase stress perception by 25%, so this simple habit is a must for managing my high-pressure days. These strategies aren’t fancy, and that’s the point. Simplicity has been my secret to consistency. By stripping away the complexity, I’ve boosted my energy, sharpened my focus, and reduced stress—without sacrificing my schedule. A 2023 study found that stress management through nutrition and lifestyle changes can improve mental clarity by up to 40%, and I feel that every day when I lead my team or tackle big decisions. Now, I’m not perfect, but these small, intentional choices have made me feel stronger and more in control than ever. So, if you’re a busy executive looking to simplify nutrition and optimize your health without the overwhelm, let’s talk. DM me “APEX” for more info on how you can do the same.
