Ketogenic Diets Slash Inflammation & Boost Cancer Recovery.
A 2025 meta-analysis in Frontiers in Nutrition examined multiple trials comparing ketogenic diets (very low-carb, high-fat) with standard diets in cancer patients. The ketogenic group experienced significantly reduced fat mass and visceral fat, lower blood glucose and insulin, and improvements in LDL, total cholesterol, as well as fatigue and insomnia.
“We Are Not Over Fat, We Are Under Muscled.”
This statement by Dr. Gabrielle Lyon isn’t just catchy—it’s scientifically sound. A 2024 Scientific Reports study analyzing nearly 11,000 adults found that a high lean mass to visceral fat ratio was tied to up to 88% lower risk of type 2 diabetes and significantly fewer cases of high blood pressure and abnormal cholesterol levels.
High Omega‑6 Intake is Fueling Chronic Inflammation.
A 2018 editorial in Open Heart by DiNicolantonio & O’Keefe highlights that the typical Western diet—with high omega-6 and low omega-3 fats—promotes inflammation linked to heart disease and chronic illness. They stress the importance of keeping omega‑6/omega‑3 ratios low to reduce inflammatory signaling like platelet aggregation and oxidative stress.
Meal Timing Matters Just as Much as What You Eat.
A 2025 narrative review in Nutrients by Reytor‑González et al. explores how when we eat interacts with our internal clocks—impacting metabolism and weight regulation. Aligning meals with natural circadian rhythms—eating more in the morning/early afternoon and less at night—may help prevent obesity and metabolic disease, even without restricting calories.
Probiotics Don’t Just Help Digestion—They Help Everything.
Two 2025 studies in Frontiers in Nutrition show that probiotics do much more than just aid digestion—they can improve mental clarity, reduce inflammation, and support healthy weight and immune function for nearly everyone.
The Sweetener in Diet Drinks That May Harm Your Blood Vessels.
A 2025 EMJ Neurology report highlights groundbreaking lab findings that the popular artificial sweetener erythritol—often found in sugar-free drinks—can impair brain blood vessel health. In simpler terms, this means erythritol could reduce blood flow to the brain and increase stroke risk.
It’s Never Too Late to Add Years to Your Life—Just Move More.
A 2025 study analyzing 85 previous studies found that people who stay consistently active have a 30–40% lower risk of early death—especially from heart disease. Even those who start exercising later in life still see a 20–25% drop in mortality risk, showing it’s never too late to change your future.
Sugar Is the World’s #3 Calorie Source And It’s Slowly Killing Us.
Globally, added sugar now makes up around 10% of total calories consumed, ranking just behind grains and produce. But while those provide some nourishment, sugar contributes little and harms much. A 2023 Annual Review study warns that sugar—not fat—is driving the chronic disease epidemic. And sugar-sweetened beverages (SSBs) are the worst offenders.
Caffeine Can Boost Your Brain—But It May Also Backfire.
According to a report from Dr. Mark Hyman’s website, caffeine is the most widely used psychoactive compound on Earth and can be both a friend and foe to your health.
This “Glyphosate Replacement” May Be Even Deadlier.
A shocking report reveals that diquat, the herbicide now replacing glyphosate in many Roundup products, is about 200× more toxic and has been shown to damage organs, kill beneficial gut bacteria, and disrupt your gut lining—according to a Friends of the Earth analysis of EPA data.
The Collapse of Bees Is the Collapse of Our Food System.
USDA scientists have linked the worst U.S. honeybee die-off on record—a staggering ~60% colony loss—to pesticide-resistant Varroa mites spreading deadly viruses, notably deformed-wing viral strains A & B, and acute bee paralysis virus. Mites resistant to the last line pesticide, amitraz, failed to stop the viral spread—signaling a massive warning for bee health and ecosystems.
Tirzepatide Could Supercharge Weight Loss And Block Tumors.
A mouse study presented at ENDO 2025 by University of Michigan researchers found that tirzepatide (marketed as Mounjaro/Zepbound) caused ~20% weight loss in obese mice and dramatically slowed breast tumor growth, linking fat loss directly to improved cancer outcomes.
Women May Benefit Even More From Creatine Than Men.
A 2021 review in Nutrients by Smith‑Ryan et al. highlights that women have 70–80% lower natural creatine stores than men, making supplementation especially impactful for their health and performance.
Gluten Sensitivity Might Be Hiding Behind Your Skin Problems.
A recent EMJ Dermatology review shows that even without celiac disease or positive blood tests, non-celiac gluten sensitivity (NCGS) can still cause persistent skin issues like dermatitis herpetiformis, eczema, urticaria, psoriasis, and chronic rashes—symptoms that often improve after adopting a gluten-free diet.
Doctors Just Found 4 Hidden Roads to Alzheimer’s.
UCLA researchers uncovered four distinct “roadmaps” leading to Alzheimer’s by analyzing longitudinal health records from nearly 25,000 patients and validating findings in the All of Us cohort. These sequential diagnostic patterns predicted dementia better than any single risk factor.
Your Gut Bacteria May Be Making You Fat—Even On a Healthy Diet.
A July 2025 study from researchers in Japan found that certain gut bacteria may block weight loss—even when you eat well. People who ate a healthy diet but failed to lose weight had higher levels of Collinsella, a microbe linked to obesity and fat storage.
Religious Belief Cuts Risk of Depression, Anxiety, and Even Death.
A growing body of research from 2020 to 2025 shows that religion and spirituality offer powerful protection against depression, anxiety, and even chronic illness.
AI That Diagnoses Better Than Doctors Is Already Here.
A 2025 Microsoft study revealed that its AI system, MAI-DxO, correctly diagnosed 85% of complex medical cases—four times more accurately than experienced physicians.
Your Personality Type Could Be Sabotaging Your Fitness Goals.
A July 2025 UCL study in Frontiers in Psychology found that when people choose exercise types suited to their personality, they enjoy workouts more and experience greater stress relief than mismatched routines.
Betaine Shrinks Fat, Revives Gut, and Reboots Metabolism.
A 2025 animal study in Frontiers in Nutrition by Wang et al. found that giving high-fat–fed rats betaine (1.5% in drinking water) for 8 weeks led to less body fat, improved blood lipids (lower triglycerides, higher HDL), and better glucose tolerance—all without cutting calories.
