Dehydration: The Negative Effects

Feb 12, 2020
 


We lose water on a daily basis. We exhale water when we breathe, we lose water through our skin as sweat and we excrete water in our urine. Without regularly replacing this fluid we become dehydrated. We can’t train our bodies to adapt to dehydration, unfortunately. It’s not something you can become good at. Even mild dehydration can have noticeable negative effects. Let’s take a look…

1. Fatigue

Perhaps the most noticeable effect of dehydration is a general feeling of fatigue. Being dehydrated is often the cause of headaches or headache-type symptoms such as reduced focus, dizziness, light-headedness, feeling tired and low mood. If you are feeling these effects, try drinking more water before jumping straight to taking painkillers.

2. Mental function

As dehydration increases, mental performance decreases. There is a noticeable impairment in short-term and working memory and our visual-motor function. Dehydration also impacts concentration and the ability to...

5 Tips to Manage Your Body Composition: Body Fat Loss for Triathletes

Oct 14, 2019


I often see endurance athletes struggling to manage their body composition. They strive to be leaner so drastically cut calories and then suffer for it with reduced energy levels, poor training performance and increased risk of illness and injury...

I despise the word ‘diet’ and don’t even get me started on ‘detox’. The idea of a quick fix is appealing but unfortunately, there is no magic pill for weight loss... 

Diets are often gimmicky, unsustainable and are not going to provide adequate fuel to keep up with the often-high load of triathlon training. There are some very real consequences to inappropriate weight loss such as altered hormones, reduced immune function, impaired growth and development and don’t forget warped psychological state (Yes, being ‘hangry’ is a real thing).

You’ll notice decreased muscle strength, anaerobic power and endurance capacity; none of which are helpful when training or racing. Success as a...

The BIA scan: A valuable measure of body composition?

Sep 25, 2019


I can’t be the only one that’s noticed Bioelectrical Impedance Analysis (BIA) scans popping up in just about every gym 12-week challenge, or ‘get fit for summer’ promo. These scans are advertised as a ‘new’ and ‘improved’ way to accurately measure your body composition that’s not going to cost you an arm and a leg. But should you be relying on this measure when it comes to achieving your goals?

It’s a BIG NO from us. Let me tell you why…

 

How BIA works:

This method of body composition measurement relies on different types of tissue in our bodies having different levels of conductivity. The machine sends a small current between the body parts in contact with the machine (either two or four points) and creates a measure of body composition depending on the response to this current. This is where we start to run into issues...

BIA machines with only two contact points (i.e. hand-to-hand, or foot-to-foot)...

Dismissing the Detox

Sep 24, 2019


This obsession with the ‘detox’ seems to come from a place of wanting to drastically reset our body. Usually following a period of indulgence in high fat and sugary foods, and probably a few too many wines or beers as well. The idea of a detox is plucked up as a saving grace as if days or weeks of denying our bodies whole foods packed with nutrients can be rapidly undone. Unfortunately, to be the bearer of bad news on this one, that’s not quite how our digestive system functions. On the flip side, you can save yourself a whole lot of money, and discomfort, by steering clear of these fads.

Clearing up the science

When it comes to toxins entering our body from food or drink, the systems we have in place to remove them are already quite good at their job without the help of a juice cleanse! Whether it’s alcohol, medication, environmental toxins or bacteria from food, there is a scientific explanation for how these toxins are eliminated. Although I could talk for...

Healthy Eating for Men

Nov 17, 2018


When men think of healthy eating for some reason, they automatically think they have to eat salad. But we’re here to tell you, you can be healthy without having to resort to boring rabbit food!

Men and women aren’t that different when it comes to daily nutrition. Yes, men tend to have more muscle mass which increases their requirements compared to a female. But nutritionally speaking, men still need a wide variety of vitamins and minerals to tick along each day. If you’re a ‘skip the veggies, pile on the meat’ type of guy, don’t worry we’re not about to suggest you turn your phone off and lock yourself at home eating chicken, broccoli and rice to meet your goals!

We surveyed all the men in our lives and found some common themes when it came to eating habits. Based on these findings, here are our Top Tips to Eating Healthy as a Dude while still balancing life and the bro-code.

Common Man Trend No. 1 – Skimping on the veggies

Eating for Mental Performance

Oct 31, 2018

As life gets busy, eating well can easily take a back-seat when there’s tight deadlines and a million other things to do! But when you’re busy, stressed and time-poor, it’s even more important to eat well to get the most out of your day.

Food is fuel for our bodies and our brain, so if you want to maximise your mental performance and get even more productive, try implementing my Top 5 Tips for Mental Performance today!

1. Choose low GI, whole grains (avoiding white)

Choosing lower GI carbohydrate sources such a whole-grain bread and cereals, brown rice, legumes etc. slows the release of glucose (sugar) into the bloodstream and your brain. This avoids those sugar highs and lows, instead drip-feeding the release of fuel to your brain so you can focus better, with more clarity for longer.

2. Include oily fish at least 3 x per week

Oily fish such as salmon, tuna, herring, mackerel are a great source of omega-3 fats which are critical for brain function...

How to Choose the Best Protein Powder

Oct 17, 2018

We have a food first philosophy here at Dietitian Approved but in some instances, protein powders can have their time and place within a healthy and active lifestyle.

As a supplement, that’s exactly what they should be used as; an addition to a balanced diet when you can’t get enough protein through real food for whatever reason.

Here are some of the reasons we might advise using a protein powder:

  • For convenience. If like us, you have a busy lifestyle and seem to always be on the run!

  • To meet protein needs directly after a heavy strength specific session – where you are trying to maximally stimulate muscle protein synthesis (building new muscle)

  • To make sure your recovery meal ticks all of the boxes when you’re in a location where real food isn’t feasible. E.g. Post-racing where your recovery meal gets delayed while you’re waiting for your medal Or if you struggle to eat post-exercise

  • To bump up the protein of a meal...

How to Beet Your Best Time and Get the Competitive Edge

Sep 16, 2018


Beetroot juice was the secret sauce for many athletes competing in the London 2012 Olympic Games. Lots of countries were using it, but it wasn’t until afterwards that the news about beetroot juice became public knowledge…

Many athletes are looking for that performance edge over their competitors. Most athletes have heard about it, but don’t know how to use it. If you’ve nailed the fundamentals of basic sports nutrition and are looking at taking your racing to the next level, try adding beetroot juice to your race plan.

 

Why beetroot juice?

What is it about this vegetable that gives you a performance kick? The component responsible for the benefits of beetroot juice is Nitrate. It’s produced within our bodies and is also found in some of the foods we eat, particularly green leafy vegetables, beetroot, processed meats and the water supply.

But the nitrate content varies widely even among the same vegetable variety. Freshness and farming practices...
