00:00Aging is inevitable, but how you age is entirely up to you.
00:04Some men hit 40 and start falling apart, losing muscle, energy, and drive,
00:09while others stay strong and sharp and full of life well into their 60s and 70s and beyond.
00:15I've seen men in the ER in their 90s who are as spry as men in their 50s,
00:19and men in their 40s who look like they're in their 90s.
00:22The difference? They understand the science of aging and how to fight it,
00:26whether they realize it or not.
00:27Science shows that you can slow down aging and prevent muscle loss and boost energy
00:31and even keep your testosterone levels high with the right strategies,
00:35and today I'm going to break down exactly how to do that.
00:38I'm Dr. Seth Capehart. I'm an emergency physician, a former military special operations guy,
00:42and I've spent the last 20 years studying human performance and health observation.
00:46I'm not here to sell you anything. This is not a sponsored video. I'm not affiliated.
00:49I have nothing to gain from this. I'm just here to give you the truth.
00:52Before we get into it, quick disclaimer. I'm a physician, but I'm not your physician.
00:55This is not medical advice. Always consult with your doctor before making any major changes to
01:00your health routine. All right, let's get into the science of aging and how to stay young and
01:04strong forever. Why do we age? The science behind it. Let's think. Aging isn't just about getting
01:09older. It's about how your cells, hormones, and metabolism change over time, and science has
01:15identified the key drivers of aging. The first factor is mitochondrial decline. Your mitochondria are
01:20the little powerhouses of your cells to create energy and fuel and muscle function and keep your brain
01:25sharp. As you age, mitochondria becomes less efficient, leading to fatigue, slower recovery,
01:30and increased fat gain. But research shows that certain lifestyle changes can slow down mitochondrial
01:36aging and even regenerate them. The second factor is hormonal decline. Testosterone levels start
01:41dropping around 1% per year after age 30, and we already have all-time lows of testosterone levels
01:47among men due to a variety of factors. But this leads to muscle loss, fat gain, lower energy,
01:52and reduced motivation. But it doesn't have to be that way. There are proven ways to maintain high
01:56testosterone naturally and, if needed, medically. Third factor is inflammation and oxidative stress.
02:02Every day, your cells experience damage from toxins, poor diet, and stress. Over time, this leads to
02:07chronic inflammation, joint pain, increased risk of heart disease, and cancers. The fourth factor is
02:13loss of muscle mass, also known as sarcopenia. If you're not actively maintaining your muscle mass,
02:18you're losing it. And less muscle means slower metabolism, higher risk of injury, and weaker,
02:23less capable body. Good news, you can fight all of these, and I'll tell you how. Step 1. Build and
02:29maintain muscle. This is your anti-aging insurance policy. If you want to stay young, strong, and
02:35capable, lifting weights is non-negotiable. After 40, you lose about 3-5% of your muscle mass per
02:41decade. If you don't do anything to stop it, that's what happens. And once you lose muscle, you lose
02:46strength, and metabolism slows down, and your energy gets worse. The solution, strength training,
02:51at least 3-4 times per week. Focus on compound movements like squats, deadlifts, presses, pull-ups,
02:57etc. These exercises stimulate the most muscle growth and keep your metabolism high as well as
03:02your testosterone high. But muscle isn't just about looking good. It's the foundation of longevity.
03:08Studies have shown that muscle mass is one of the biggest predictors of longer health life.
03:12People with higher muscle mass have lower disease risk, better metabolic health, and
03:17more mobility as they age. So, don't make the mistake of only doing cardio. Cardio is great for
03:22your heart, but if you ignore strength training, you're accelerating aging. The goal isn't to live
03:28long. It's to be strong and capable while doing it. Step 2. Optimize your testosterone and hormones.
03:34Your hormones control how you feel, how you recover, how you age. And testosterone is the king
03:40of male hormones. If you let testosterone drop unchecked, you'll lose muscle, gain fat, and feel
03:45sluggish. But there are ways to keep your testosterone levels high naturally. First, focus on key nutrients
03:51that support testosterone. Zinc, magnesium, boron, vitamin D, healthy fats. These are the building blocks
03:57of testosterone production. I have an entire video on it. Second, manage stress. Chronic stress elevates
04:03cortisol, which lowers testosterone and speeds up aging. Meditation, cold exposure, and even
04:09disconnecting from screens can help regulate stress and support healthy hormones. Third,
04:14prioritize your sleep. Your body makes testosterone while you sleep. If you're only getting five or six
04:20hours per night, your testosterone levels can drop by 15 to 20%. Aim for seven to nine hours and focus on
04:26deep, high quality sleep. You need to start tracking it. Use one of the tracking rings or your Apple watch
04:31and get it down. Finally, if your testosterone is clinically low, you may need to consider TRT,
04:37also known as testosterone replacement therapy. It's not for everyone, but for men with legitimately
04:42low T levels can be life-changing. Step three, use fasting and nutrition to slow down aging. What you
04:49eat and when you eat affects how you age. Intermittent fasting has been shown to increase growth hormone,
04:55improve insulin sensitivity, and trigger autophagy as well as increase lifespan in general. Autophagy is a
05:00process where your body cleans out damaged cells and regenerates new ones. A great approach is the 16-8
05:05fasting window where you fast for 16 hours and then you eat in an eight-hour window. This helps
05:10control blood sugar, boost metabolism, reduce inflammation, fight cancer, things like that.
05:15When you do eat, prioritize proteins and healthy fats. Steak, eggs, wild-caught fish, avocados,
05:20olive oils. These are all support hormone production, muscle maintenance, and brain function. Avoid
05:26processed junk. I like seed oils and refined sugars. These drive inflammation, weight gain, hormone
05:30imbalances. They cause type 2 diabetes and cardiovascular disease. The cleaner your diet,
05:35the slower you age. Step four, move daily and stay mobile. You don't just want to be strong. You want to
05:42be mobile, pain-free, and athletic for life. Incorporate daily movement outside of your workouts.
05:48Walk 8-10,000 steps per day. Stretch or do mobility work. Stay active outside the gym. Play sports. Shoot
05:55some hoops. Go swim. Have fun with your kids. Joint pain, stiffness, and low energy aren't just
06:01normal aging. These are results of a sedentary lifestyle. Keep moving and your body will stay
06:06young longer. Final thoughts. The blueprint for staying young and strong. If you want to fight
06:12aging, stay strong for life. Here's the plan. 1. Lift weights, build muscle. It's your anti-aging
06:18insurance policy. 2. Optimize testosterone with diet, sleep, and stress management. 3. Use fasting and
06:24high-quality nutrition to reduce inflammation and boost longevity. 4. Move daily. Walk, stretch,
06:30play sports. Stay mobile. Aging doesn't have to mean getting weak and broken. You can stay lean.
06:35You can stay strong. You can stay full of energy if you take control now. Don't wait till you're 70.
06:40Do it now so that when you are 70, you feel like you're 30. If you want to take this even further,
