The Amazing Benefits of Walking


1. Improve your mood.

A glass of wine or a square (or three) of dark chocolate can blunt the edge of a rough day—but going for a walk is a zero-calorie strategy that offers the same perk. In fact, research shows that just 10 minutes of walking can lift your spirits. 

Research shows that regular walking actually modifies your nervous system so much that you’ll experience a decrease in anger and hostility, especially when you’re going for a stroll through some greenery or soaking in a bit of sunlight. This can be particularly helpful during the colder months, when seasonal depression spikes.

2. Burn calories and maintain a healthy weight

As you continue to walk, you may notice your pants begin to fit more loosely around your midsection, even if the number on the scale isn’t moving much. That’s because regular walking can help reduce fat and, as a result, improve your body’s response to insulin, according to research. 

Itching to up your calorie burn? When walking outside, plan a route that includes hills, alternate between speed walking and a slower pace, and challenge yourself to walk the same routes on different days to see if you can beat your previous times. For an extra boost of motivation aim to hit 10,000 steps a day.

Daily walking increases metabolism by burning extra calories and by preventing muscle loss, which is particularly important as we get older.

3. Reduce your risk of chronic diseases

The American Diabetes Association recommends walking to lower blood sugar levels and lower your overall risk for Type 2 diabetes. Some research even shows that for every 1,000 daily steps you take, you could lower your systolic blood pressure by .45 points. That means if you clock in 10,000 daily steps, your systolic blood pressure is likely to be 2.25 points lower than someone else who walks only 5,000 daily steps.

One of the most cited studies on walking and health, published in The New England Journal of Medicine, found that those who walked enough to meet physical activity guidelines had a 30% lower risk of cardiovascular events (like a heart attack or stroke) compared with those who did not walk regularly. For disease prevention, longer walks are key. We recommend doing one hour-long walk at least once or twice a week.

4. Live longer

That’s right, walking can seriously help you add years to your life, and it doesn’t take much to see results. In fact, one study found that people who did just 10 to 60 minutes of moderate exercise (like brisk walking) per week had an 18% lower risk of death during the study period compared to those who were inactive. Meanwhile, people who completed the recommended 150 minutes of weekly exercise in at least 10-minute spurts had a 31% lower risk of death. Other research shows the faster you walk, the more your risk drops. The longer life benefit is believed to come from the cardiorespiratory workout that walking provides.

5. Boost your brainpower

The research here is quickly growing. In one study, brain scans of people who walked briskly for one hour three times a week showed the decision-making areas of their brains worked more efficiently than people who attended education seminars instead. Other research shows physical exercise, like walking, can improve brain function in older women. Experts think these benefits could be due in part to increased blood flow to the brain that occurs with exercise. So when you get your feet moving, your brain starts working better too!

6. Alleviate joint pain

Contrary to what you might think, pounding pavement can help improve your range of motion and mobility because walking increases blood flow to tense areas and helps strengthen the muscles surrounding your joints.

In fact, research shows that walking for at least 10 minutes a day—or about an hour every week—can stave off disability and arthritis pain in older adults. A 2019 study in the American Journal of Preventive Medicine followed 1,564 adults older than 49 with lower-body joint pain. Participants who walked for an hour each week were more likely to remain disability-free four years later. An additional report found that walking was a safe, inexpensive, and convenient physical activity for those with arthritis of all fitness levels.

7. Delay the onset of varicose veins

As you age, your risk of varicose veins increases. However, walking is a proven way to prevent them from developing. The venous system includes a circulatory section known as ‘the second heart,’ which is formed by muscles, veins, and valves located in our calf and foot. This system works to push blood back up to the heart and lungs—and walking strengthens this secondary circulatory system by strengthening and preserving leg muscle, which boosts healthy blood flow.

If you already suffer from varicose veins, daily walking can help ease related swelling and restlessness in your legs. Also, if you are genetically predisposed to have varicose and/or spider veins, walking daily can help delay the onset.

8. Stimulate your digestive system

If you currently count on your daily dose of coffee for keeping your digestive system going strong, get ready to start thanking your morning walk instead. That’s because a regular walking routine can greatly improve your bowel movements. One of the very first things an abdominal surgery patient is required to do is to walk because it utilizes core and abdominal muscles, encouraging movement in our GI system. In other words, when you start moving, your bowels start moving too.

9. Enhance creativity

Whether you’re feeling stuck at work or you’ve been searching for a solution to a tricky problem, research shows it’s a good idea to get moving: According to a 2014 study in the Journal of Experimental Psychology, Learning, Memory, and Cognition, going for a walk can spark creativity. Researchers administered creative-thinking tests to subjects while seated and while walking and found that the walkers thought more creatively than the sitters.

10. Improve your sleep

If you work out regularly, you’ll sleep better at night. That’s because physical activity naturally boosts the effects of melatonin, the sleep hormone. A 2019 study from Sleep found that postmenopausal women who do light to moderate-intensity physical activity snooze better at night than those who are sedentary. Another recent study found healthy adults who walked daily had a significant positive impact on sleep quality and length of sleep. Walking also helps reduce pain and stress, which can cause sleep disturbances.

11. Kickstart your immune system.

In this era of pandemics and super-viruses, we’re all looking for ways to improve our immunity, and walking is a great place to start. Research shows that moderate-intensity exercise and walking in particular ramps up our immune system. It increases the number of immune cells that attack pathogens in our body, which lowers your risk of becoming seriously ill from infectious diseases. Not only that, if you do get sick, research has found that people who walk more spend less time in the hospital. One study even found those who walked regularly could reduce their risk of dying from pneumonia compared to those who don’t exercise regularly.

12. Make other goals seem more attainable.

When you become a regular walker, you will have established a regular routine—and when you have a routine, you are more likely to continue with the activity and take on new healthy behaviors. Our bodies are not meant to be sedentary all day. Any type of movement is better than no movement, and being able to find a type of movement best suited for your age and fitness level is super important so you feel empowered and motivated to stick with it.

Walking for older individuals is a great gateway exercise to get your muscles moving and your heart elevated. You can also speed it up to more of a speed walk to increase your heart rate. Plus, walking can help you believe in yourself and your health goals.

How Much Protein Can You Absorb In One Meal


Let’s begin by defining absorption. This term is used to describe the process of the foods we consume traveling through our digestive system, and the nutrients within them being absorbed and put into circulation. There are certain factors, such as the type of protein you’re consuming, which affects the ways in which your body can absorb it, and therefore the digestibility of the protein overall. In short, absorption refers to the amount of protein which ends up in your bloodstream from what you ingest. 


How much protein can your body absorb in one go?


Let’s dive right in with the most commonly held belief that the body can only absorb 20-25g of protein at one time, and that anything else will be excreted and not used.


Certain studies have shown that there is almost no limit to the amount of protein our bodies can absorb, but the more protein you consume in one go, the longer it will take to digest. There are other factors which affect this, such as the content of certain amino acids within the protein you are consuming. Leucine, for example, has been shown to trigger muscle protein synthesis, so the lower the leucine content in the protein, the more you may need to trigger beneficial muscle protein synthesis. High leucine protein sources include pumpkin seeds, hemp seeds, lentils, and spirulina. If you are looking to improve your muscle protein synthesis, then a protein powder with branched chain amino acids that include leucine, may well be beneficial for your muscle growth, tone and definition.


You’ll also need to be aware of your current musculature and tone. The more muscular you are, the more protein you’ll need for muscle protein synthesis. Does this mean that you should only eat a certain amount of protein in one go? The answer to this is, not necessarily. Understanding your own training schedule, macros and the types of protein you’re consuming are all important factors in determining how much protein is right for you.


Should you spread your protein consumption out throughout the day?


As we now know, our bodies do not stop absorbing protein when we’ve ingested 20-25g, so the secondary question of whether or not this has any impact on our ability to build muscle comes into play. Certain studies have shown that more than 20g of protein in one sitting has little to no effect on muscle protein synthesis, meaning that if we’re eating heavy amounts of protein in order to grow more muscle, eating more than 20-25g in one go won’t give us more muscle at a faster rate than if we were having small amounts of protein spaced throughout a day. In fact, research does show that it is your total protein intake over the course of the day which is the most important factor for muscle gain, and athletes may benefit from spacing out their protein intake to make the most of the opportunities for muscle protein synthesis, growth and repair.


There are certain risks associated with eating a continuous, excessively high protein diet. Whilst it doesn’t necessarily matter if you fill all of your protein requirements in one meal, consistently eating a lot more protein than you need can have a negative impact, especially if you have any chronic kidney conditions, and certain liver conditions. This is because breaking down protein creates byproducts such as ammonia. If there are reasons why your body might not be able to excrete excess ammonia, then a higher protein diet might cause unnecessary complications.
