Because of receptor density. Lower belly fat has a higher concentration of alpha-2 adrenergic receptors, which block fat mobilization. Upper body fat has more beta-2 receptors, which release it easily. It's not effort. It's receptor biology. The last fat to arrive is the last to leave.

why is lower belly fat so hard to reduce?🤦🏾‍♀️

@KevinSzabo14 Start building muscle now. Seriously. Testosterone peaks in your 20s and muscle is dramatically easier to build then than at 35. The physique you build in your 20s becomes your baseline for the rest of your life. Muscle=life.

Message to all young adults: You actually don’t have as much time as you think.. Your 20’s go by quick. Stop waiting around and start now. And if you’re older, what’s one advice you’d give?

The unilateral cable preacher is underrated for one specific reason: constant tension. Unlike a barbell curl, the cable maintains resistance at full extension, where the bicep is most stretched and mechanically weakest. That stretch-loaded tension is one of the strongest drivers of hypertrophy we know of.

It’s NOT even up for debate… These are a TOP 5 Biceps exercise known to man If you try them…all I have to say is: YOU ARE WELCOME IN ADVANCE

@AlpacaAurelius There's hard science behind this. Chronic fear activates the HPA axis and keeps cortisol elevated. Sustained cortisol suppresses T-cell function and increases systemic inflammation. The anxiety about toxins can be more immunosuppressive than the toxins themselves.

the greatest challenge in the health world: FEAR of sickness causes sickness. if you walk around terrified of seed oils, terrified of the sun, terrified of BPA and plastics, you're jacking up your nervous system and hurting your health way more than just doing the thing. yes, you should avoid toxins. but not out of fear. out of love for your body and from the beautiful life you want to live. namaste friends.

@dr_ericberg Vitamin D is the most underrated one. It doesn't just support immunity, it directly regulates the expression of over 200 genes involved in immune response. Most people are deficient without knowing it, especially in low-sunlight climates.

Getting sick all the time is not always just “bad luck”. Low vitamin D, zinc, selenium, and other missing nutrients can weaken your immune defenses long before symptoms start showing up. One common deficiency plays a much bigger role in immunity than most people realize. drbrg.co/4nuYUeQ Dr. Eric Berg, DC, not MD; information only

@SamaHoole The shared mechanism is mTOR activation. Heavy mechanical load triggers mTOR regardless of rep range. The difference between "strength" and "hypertrophy" protocols is largely a fitness industry invention. Pick a rep range. Get stronger in it. The size follows

Growing up is realising that you don't have to pick between size and strength. You don't have to vary your rep ranges either. 4-6 reps near failure produces both. Same set. Same weight. Same protocol. - Maximum mechanical tension (drives hypertrophy) - Heavy loads recruiting high threshold motor units (drives strength) - Neural adaptation that translates directly to bigger lifts - Cross-sectional growth that supports the new strength - Manageable fatigue that lets you progress week to week Strength and size are not competing adaptations needing separate protocols. They're the same adaptation seen from two angles. The muscle that's stronger is bigger. The muscle that's bigger is stronger. Shared mechanism. The lifter doing 4-6 reps for two years has added 50kg to their bench and 8kg of muscle to their frame. The lifter alternating between "strength blocks" of 3-5 reps and "hypertrophy blocks" of 8-12 reps has done neither as well, and now needs a deload because they've been riding a wave they didn't need to ride. Pick one rep range. Make it 4-6. Add weight. Wait.

@connorpaton There's actual science behind this: orthosomnia. The anxiety of tracking sleep metrics can itself impair sleep quality. The measurement becomes the problem. Data is only useful when it informs behavior, not when it replaces body awareness.

my whoop died two weeks ago and i've been sleeping like a baby ever since turns out i wasn't tracking my health i was just giving my anxiety a scoreboard founders run on placebo half the time anyway you tell yourself you're fine enough times and your body eventually believes it cold plunge, morning routine, "i'm locked in" on twitter it's all the same trick honestly the best founder skill nobody talks about is convincing your own body to shut up and keep going

Two things happening: Carbs spike insulin, which drives tryptophan into the brain and converts to serotonin. That's the "full and calm" feeling. For strength, glycogen from carbs is the primary fuel for high-intensity muscle contractions. More glycogen = more output. Your body isn't confused. It's just telling you what it runs best on.

High carb and lower protein keeps me fuller for longer and makes me stronger can someone help me understand why this is happening ?

@dr_ericberg The link makes sense physiologically. Thyroid hormones regulate bile acid synthesis in the liver. Hypothyroidism slows bile production and flow, increasing cholesterol saturation in bile, which is the main precursor to gallstone formation. Two systems, one hormonal root.

Gallstones and thyroid problems may be more connected than most people think. Low bile flow can affect hormone balance, fat digestion, and how your body uses key nutrients every single day. The real trigger behind gallstones might have nothing to do with fat at all. drbrg.co/4wNOJqn Dr. Eric Berg, DC, not MD; information only

@rajmichaelsfit Not far off. Chewing increases arousal and alertness via the trigeminal nerve and slightly elevates cortisol and heart rate. The 37% is yours, but the mechanism is real.

Chewing gum during workouts somehow makes me feel 37% stronger

@NOgymNOlimits 279g de proteína en 900g de producto es bioquímicamente impresionante y gastronómicamente aterrador.

Qué barbaridad, se les está yendo la pinza. En serio. Tienen que parar esto.

Veredicto científico: 🏃 Si entrenas → melón. Más potasio y vitamina C para recuperarte. ❤️ Si cuidas el corazón → sandía. Licopeno y L-citrulina. ☀️ Si solo quieres el verano → la que más te guste. La ciencia no prohíbe. Informa.

¿Y el azúcar? Toca hablarlo. Melón: 7.9g por 100g Sandía: 6.2g por 100g El melón tiene algo más. Pero su índice glucémico es moderado en cantidades normales. No hay fruta que te engorde. Hay contextos que sí.

Melón vs Sandía. 🍈🍉 La fruta que eliges en verano puede marcar la diferencia en tu recuperación, tu corazón y tu rendimiento. No es lo mismo. Te explico por qué. 🧵

The mechanism goes deeper: morning cortisol also increases platelet aggregation and blood viscosity. Your blood is literally thicker and more prone to clotting in the first hours after waking. That's why aspirin timing, blood pressure meds and even exercise timing matter more than most people realize.

Nearly 50 percent of heart attacks happen between 6:00 a.m. and 12:00 p.m., likely connected to morning cortisol levels. Cortisol and adrenaline both increase clotting, so managing stress is important. Dr. Eric Berg, DC, not MD; information only

@ferrisbuhler81 The mechanism behind it: mechanical load on bone triggers osteoblast activity, the cells responsible for bone formation. Strength training doesn't just build muscle. It signals the skeleton to stay dense. The best osteoporosis treatment is the one that starts at 30, not 60.

Muscle is armor. Bone density is your foundation. And the earlier you track both, the more control you have later. For too long, women were scared away from real hormone conversations while osteoporosis became a billion-dollar market. Strength training. Bone scans. Hormone optimization. That’s prevention.
