Gaining lean muscle mass

Tips for men who want to build muscle effectively and gain lean muscle mass

In order to grow your muscles, you must apply enough stress for them to become fatigued. — 123rf.com

For most males, hitting the gym is a way to get healthy, look good and feel more confident.

To get the most out of a workout session, a good understanding of health and nutrition can help maximise results.

However, if you were to ask most men what it takes to build muscle, they’d probably say that you just need to eat protein, protein and more protein.

Sure, protein is important.

After all, your muscles are made of protein, and your body requires adequate protein in the diet in order to have the building blocks it needs to build muscle mass.

But protein alone won’t do.

You also need to pay attention to the rest of your diet and exercise routine.

To help men start off on the right track, here are some tips on how to build muscle effectively.

Strike the right balance

A lot of people who are trying to bulk up are also trying to lose body fat at the same time.

But sometimes, the approaches they use to meet those goals are at odds with each other.

They’ll take in plenty of protein, which, when coupled with a strength training routine, should lead to more lean mass.

But they may also cut their total calories back too far in an effort to get “shredded.”

That can be a problem.

If you cut your calories too much, some of the protein that you eat is going to be burned for fuel rather than being used to support muscle development.

So, to effectively build muscle mass, you want to ensure that you have enough calories to support your activity and the right balance of nutrients.

Fuel up with carbohydrates

Many bodybuilders see carbohydrates as the enemy, and that can be a mistake.

Yes, highly refined carbohydrates and snacks hardly do the body good.

But the right carbohydrates help to fuel activity, including working muscles.

Good sources can be found in whole grains, beans, fruits and vegetables.

Without adequate carbohydrates to fuel your exercise, some of the protein you’re eating might get burned for fuel.

So, to avoid “burning the candle at both ends,” make sure to include enough high-quality carbs in your diet.

Get some healthy fats

Dietary fat is sometimes underappreciated by some athletes. Like carbohydrates, fats may have an undeserved bad reputation.

Small amounts of the right kinds of fats are very important.

That’s because certain fatty acids, the building blocks of dietary fats, are essential as the body can’t make them.

Fatty acids are a vital structural component of every cell membrane, including muscle cells.

The body relies on fat to fuel moderate intensity, longer-term exercise.

That’s just the type of exercise that might be coupled with a strength training regimen to build mass and lose body fat.

Good sources of fatty acids include nuts. seeds, fatty fish, olive oil and avocado.

Protein intake and timing are key

Protein is crucial for muscle development, but instead of simply focusing on the amount of protein you take in, you should also pay attention to the timing of your intake.

The process of muscle protein synthesis (MPS) is stimulated by strength training activity, but it’s also stimulated when you eat protein.

This is one reason why those looking to bulk up should aim to spread their protein intake evenly over meals and snacks throughout the day.

MPS is greater under these conditions than it is under a more typical pattern in which little protein is consumed in the morning, a bit more at lunch, and then a large amount at dinner.

And, a bedtime snack containing about 25g of protein can help to stimulate MPS during the night.

Both plant-based and animal- based protein sources provide the necessary building blocks for MPS, but different proteins are digested and absorbed at different rates, so taking in a variety of protein sources could allow a prolonged release of amino acids into the system.

For example, dairy products contain two proteins: whey and casein.

Whey is considered a “fast-acting” protein, while casein takes longer for the body to process.

It’s the reason why many athletes turn to dairy proteins since they provide a sustained release of amino acids over a longer period of time.

However, animal proteins aren’t necessary in order to build muscle.

With careful planning and attention to total intake, even vegetarians and vegans can consume enough protein to support muscle development.

A fruit and milk/soy smoothie or yoghurt is a good recovery food option after a strength training session.

Best diet tips

> How to spread your protein intake, and how often should you eat?

Ideally, you’ll want to time your eating so that it works with your workout, but also aim for three regular meals and a couple of snacks – making sure that they are balanced with both carbohydrates and protein.

That way, you can provide your body with the fuel it needs from the carbohydrate, as well as a steady supply of protein to stimulate MPS.

> What to eat before a workout?

You want to start your workout well-hydrated and well-fuelled.

For fluids, drink about two cups of water two to three hours beforehand, then have another cup about 15-20 minutes before.

The length of time between the time you eat your meal and the time you work out will dictate the type of meal you have:

If you have a few hours to digest, then a balanced breakfast that might include foods like eggs, yoghurt, whole-grain toast or cereals, milk/soy milk, and fruit would be appropriate.

If you’ll be eating fairly close to the time you work out, then something like a protein shake will take less time to digest.

Just be sure your shake includes not just protein but a source of carbohydrates, too.

So, in addition to a protein powder and/or milk or milk alternatives, include foods such as fruits and vegetables (such as carrots or sweet potato); you can even toss in some rolled oats.

> What to eat after a workout?

After you exercise, your muscles need some healthy carbohydrates and about 10-20g of high-quality protein to help them repair and recover.

A tub of yoghurt, a turkey or nut butter sandwich, a smoothie made with fruit and milk or soy milk, or a bowl of cereal and fruit are all good recovery foods after a session of strength training.

> What are good snacks in between meals?

Snacks should include the same healthy balance of protein and carbohydrates.

Some snack bars have a good balance of protein and carbohydrates and are convenient to carry with you.

Other quick snacks include a hard-boiled egg with whole grain crackers, yoghurt with fruit, or raw vegetables and hummus.

> How to gain muscle without putting on fat?

In order to build muscle, your body does require additional nutrients and calories, but that doesn’t give you licence to eat as much as you want.

If you take in more calories than you burn – whether from unhealthy, fatty, sugary foods or from a healthy well-balanced diet – those calories will get stored as body fat.

Choosing lean proteins, such as fish, poultry, low-fat dairy products, beans and tempeh, will help ensure that your body gets the protein it needs without excess calories.

Similarly, choose healthy carbohydrates – fruits, vegetables, whole grains – over sugars and refined starches, so you can reap the benefits without the extra calories.

Designing a plan

You need more than just protein in your diet to get the nutrients you need to build muscle.

The same applies to your exercise routine – doing the right workouts will help you reach this goal faster and more effectively.

Sports performance and fitness specialist, Denise Cervantes, shares her favourite tips for strength training.

Strength training, also known as resistance training, is the main form of exercise you want to focus on to build muscle.

These exercises include weightlifting or bodyweight training (without weights) to improve your strength and strength endurance.

When you are training to increase strength or gain muscle, there are two things you need to make sure you are doing in your training to initiate the physiological change for hypertrophy (muscle growth in size).

First, you need to make sure you are creating mechanical tension, meaning you are using a heavy enough weight to challenge the muscle through a full range of motion.

Secondly, your training must also cause metabolic stress.

You will know you have done so when your muscle becomes fatigued, because it has used all of its stored energy to fuel its contractions to complete the repetitions.

This is a good thing!

These stresses you apply to the muscle will cause damage to the muscle fibres, causing “micro-tears,” which then send signals for the cells to regrow stronger and bigger.

And remember, growth happens with rest, so make sure to follow a well-designed programme that gives you a day to rest the muscle you just worked so it has a chance to recover and grow.

To see continual improvements from strength training, you should gradually increase the weight and number of repetitions.

Pretty soon, you’ll be a lot stronger physically and attracting a lot of attention!

Humans are nutritionally wise; Say goodbye to daily aspirin

Our food choices may be smarter than previously thought.

Researchers say our food choices may be influenced by nutritional requirements rather than calories.

PIONEERING research has shed new light on what drives people’s basic food preferences.

The international study, led by the University of Bristol, United Kingdom, set out to re-examine and test the widely-held view that humans evolved to favour energy dense foods and our diets are balanced simply by eating a variety of different foods.

Contrary to this belief, its findings revealed people seem to have “nutritional wisdom,” whereby foods are selected in part to meet our need for vitamins and minerals, and avoid nutritional deficiencies.

Lead author Jeff Brunstrom, professor of experimental psychology, said: “The results of our studies are hugely significant and rather surprising. For the first time in almost a century, we’ve shown humans are more sophisticated in their food choices, and appear to select based on specific micronutrients rather than simply eating everything and getting what they need by default.”

The paper, published in the journal Appetite, gives renewed weight to bold research carried out in the 1930s by an American paediatrician, Dr Clara Davis, who put a group of 15 babies on a diet which allowed them to “self-select”, in other words eat whatever they wanted, from 33 different food items.

While no child ate the same combination of foods, they all achieved and maintained a good state of health, which was taken as evidence of “nutritional wisdom”.

Its findings were later scrutinised and criticised, but replicating Dr Davis’ research was not possible because this form of experimentation on babies would today be considered unethical.

Hence, it has been nearly a century since any scientist has attempted to find evidence for nutritional wisdom in humans – a faculty which has also been found in other animals, such as sheep and rodents.

To overcome these barriers, Prof Brunstrom’s team developed a novel technique which involved measuring preference by showing people images of different fruit and vegetable pairings so their choices could be analysed without putting their health or well-being at risk.

In total 128 adults participated in two experiments.

The first study showed people prefer certain food combinations more than others.

For example apple and banana might be chosen slightly more often than apple and blackberries.

Remarkably, these preferences appear to be predicted by the amounts of micronutrients in a pair and whether their combination provides a balance of different micronutrients.

To confirm this, they ran a second experiment with different foods and ruled out other explanations.

To complement and cross-check these findings, real-world meal combinations as reported in the UK’S National Diet and Nutrition Survey were studied.

Similarly, these data demonstrated people combine meals in a way that increases exposure to micronutrients in their diet.

Specifically, components of popular UK meals e.g. fish and chips or curry and rice, seem to offer a wider range of micronutrients than meal combinations generated randomly, such as chips and curry.

The study is also notable as it features an unusual collaboration – Prof Brunstrom’s co-author is Mark Schatzker, a journalist and author.

In 2018, the two met when Schatzker delivered a talk about his book, The Dorito Effect, which examines how the flavour of whole foods and processed foods has changed, and the implications for health and wellness.

Prof Brunstrom explained: “Mark challenged the view among behavioural nutrition scientists that humans only seek calories in food. He pointed out, for example, that fine wine, rare spices and wild mushrooms are highly sought after but are a poor source of calories.

“This was all very intriguing, so I went to see him at the end and basically said: ‘Great talk, but I think you’re probably wrong. Do you want to test it?’

“That marked the start of this journey, which ultimately suggests I was wrong. Far from being a somewhat simple-minded generalist, as previously believed, humans seem to possess a discerning intelligence when it comes to selecting a nutritious diet.”

Schatzker added: “The research questions the modern food environment – does our cultural fixation with fad diets, which limit or forbid consumption of certain types of foods, disrupt or disturb this dietary ‘intelligence’ in ways we do not understand?”

“Studies have shown animals use flavour as a guide to the vitamins and minerals they require.

“If flavour serves a similar role for humans, then we may be imbuing junk foods such as potato chips and fizzy drinks with a false ‘sheen’ of nutrition by adding flavourings to them.

“In other words, the food industry may be turning our nutritional wisdom against us, making us eat food we would normally avoid, thus contributing to the obesity epidemic.” - The Star Malaysia

Say goodbye to daily aspirin

Daily aspirin no longer recommended for adults 60 and older

Doctors reverse recommendation on daily aspirin

THIS might be a tough pill to swallow.

People aged 60 and older are no longer recommended to take aspirin medication as a way of avoiding heart disease because of the potential health risks, the United States Preventive Services Task Force (USPSTF) announced last week.

The new stance by the leading task force serves as an update to its 2016 guidance, which said people between 60 and 69 years old with at least a 10% risk of suffering from cardiovascular disease over the next 10 years should view taking low-dose aspirin daily as an “individual” decision.

“Based on new evidence since the 2016 Task Force recommendation, it is now recommended that once people turn 60 years old, they should not consider starting to take aspirin because the risk of bleeding cancels out the benefits of preventing heart disease,” reads the announcement by the USPSTF.

Meanwhile, people aged 40 to 59 with at least a 10% risk of 10-year cardiovascular disease should look at taking daily aspirin as an individual choice, the task force said.

“Daily aspirin use may help prevent heart attacks and strokes in some people, but it can also cause potentially serious harms, such as internal bleeding,” John Wong, a member of the task force, said in a statement.

“It’s important that people who are 40 to 59 years old and don’t have a history of heart disease have a conversation with their clinician to decide together if starting to take aspirin is right for them.”

The new guidelines apply to people who don’t have cardiovascular disease but are at high risk to develop it and haven’t begun taking aspirin each day.

The organisation also notes that about 605,000 people in the US suffer their first heart attack each year on average, while about 610,000 have their first stroke.

Heart disease accounts for more than 25% of deaths in the US, making it the leading cause in the country.

Aspirin is an anti-inflammatory drug that has been used for more than a century. It’s often taken to treat symptoms such as headaches, body aches and other cold-like ailments.

The task force is made up of 16 appointed volunteers who are each considered leaders within a field of health or medicine.- TNS
