Vegan vs Keto - for Athletes

Beautiful meal at Trofeo Estate Mornington Peninsula - unintentionally vegan vs keto!

Vegan. Keto.  Two approaches to food and nutrition that in principal could not be further apart, but are promoted by their respective loyal followers as the only way to eat.  Promises of weight loss, mental clarity, digestive health, improved performance and a range of health benefits - clever marketing may convince even the most well-read individual of the benefits of plant-based or carnivorous consumption.

I work with people who follow a vegan lifestyle.  I also work with individuals who are interested in a keto approach.  Both have pros and cons. Yes, there are significant differences, but also similarities that align with universally agreed healthful nutrition strategies - inclusion of vegetables for example.  Neither are fads and both dietary preferences will be with us for many years to come, as will the debate over which style is superior for associated health benefits.  But is one or the other superior for athletes and sports performance?  The type of athlete, and person, you are may be the key to determining whether plant-based vegan or carnivorous keto is the way to go - or something else entirely.    

Vegan virtuosity

‘Veganism is a way of life that seeks to exclude, as far as is possible and practicable, all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose’ (The Vegan Society).  

Vegan is a lifestyle rather than a diet. There is an increasing trend towards plant-based eating, with significant research supporting the benefits from a health perspective.  The spotlight has recently shone on plant-based for sports performance, ably assisted by the ‘Gamechangers’ program, promoting the virtues of plant-based nutrition for performance, but which also has been widely criticised for its erroneous scientific claims.

A vegan approach to nutrition involves elimination of all animal foods including meat, poultry, fish and seafood, dairy, eggs and honey, and includes wholegrains, fruits, vegetables, nuts/seeds, legumes and products manufactured from these.  A well-balanced vegan diet can provide the wide range of nutrients required for human health and performance, but without significant effort and planning, athletes may find themselves falling short on nutrients, with a subsequent impact on performance outcomes. 

Benefits of a vegan diet for athletes

-        Adequate fibre, vitamin and mineral intake when well balanced (supplementation required)

-        Weight loss (but sometimes gain)

-        Energy levels

-        Provides carbohydrate for high-intensity fuel

-        Digestive health

Potential concerns of a vegan diet

-        Nutritional inadequacies eg. Vitamin B12, Iron, Calcium, Omega-3

-        Restrictive eating patterns

-        Over consumption of specialised vegan processed foods

-        Protein quality and quantity (you have to plan well)

-   Supplement use vs natural food sources

What is keto?

Keto, ketogenic, low-carb/high-fat (LCHF) - however you label it, this style of eating promotes the use of fat as a fuel, along with ketone production (which can also be used as a fuel).  Carbohydrate is restricted to less than 20g/day, with moderate protein (not high) and unlimited amounts of dietary fat, usually with no prescription as to the type or source. 

What does this look like? Plenty of high fat foods like meats and poultry, cheese, cream, eggs, butter, oils, nuts and seeds, while cutting out all wholegrains, fruit, legumes, many vegetables and most dairy, as well as many processed foods.  Not much flexibility in this type of approach, especially if ketosis is the goal.  The modified versions of LCHF allow some carbohydrate flexibility, but on the whole, restriction is the name of the game to achieve the proposed benefits. 

The keto approach has gained much interest in the strength training world for it’s potential to support body composition goals, and in ultra-endurance ranks for increasing the ability to use fat stores as an effective fuel source for prolonged steady-state exercise.

Anecdotal evidence for a positive effect on performance is widespread, however hard evidence from the scientific world is lacking with regard to the impact of keto on high-intensity performance. Some studies indicate a potential risk of impaired performance when high intensity effort is required.

Benefits of keto for athletes:

-       Weight loss (for some people, not all)

-       Improved gastrointestinal symptoms (for some, particularly if existing intolerances)

-       Improved blood glucose levels

- High quality protein

-       Less processed, more natural foods

-       Improved use of fat as a fuel - this does not necessarily = improved performance

Potential keto concerns

-        Inadequate intake of specific nutrients, particularly those found in wholegrains, fruit, starchy vegetables and legumes

-        Gut health

- Excessive meat intake

-        Low energy levels (for some)

-        Impact on brain function, concentration (for some)

-        Restrictive and difficult to stick to

- Impact on an individual’s relationship with food and enjoyment of food

- Negative impact on sports where high-intensity effort required

- Impaired ability to use carbohydrate as a fuel when needed

- Potential impact on dietary nitrate conversion

Vegan keto combo

Yes, it’s a thing, but to be honest I wouldn’t bother.  Many of the vegan sources of protein also contain carbohydrate – so to get nutritional variety and keep carbohydrate at a keto level, it would be challenging to meet overall nutrition needs.  Let’s just say you would likely be eating a bunch of tofu and olive oil and very likely missing out on important minerals. I have not done the modelling for this though - perhaps a good project if anyone is keen to look into this further, or let me know if there are existing resources on this.

Vegan vs keto for performance

The issue with vegan vs keto for sports performance is that there are potential downsides to both. 

A vegan approach provides plant-based nutrient diversity and associated benefits, but without precision planning can result in poor nutrition intake and protein balance. But usually plenty of carbs!

Keto is an approach that seems to be growing in popularity, but the evidence to support its effectiveness for high-intensity performance is lacking at present.  Keto has been shown to enhance fat oxidation in athletes, but this has not consistently translated to performance effects.  If you are an ultra-endurance athlete, where steady state exercise is your thing and you are less likely to need high-intensity bursts, then the ability to burn more fat may be pretty handy.  But if you are a team sport contributor, and need to use your speed and agility to get to a pass or defend a goal, then carbs are the best fuel to help you get there.  Keto might just not cut it.

Part-time keto?

Some athletes will turn to a keto, or lower carbohydrate, style of eating during specific times of the year or training phases - for example early in pre-season when aerobic fitness may be a priority, along with reducing body fat levels. As training intensity steps up, carbs can be re-introduced and timed appropriately around training sessions and to suit training goals. If you need to train hard, carbs are critical.  So is protein, for recovery - and this is where vegan nutrition can let you down if not well planned. But a vegan diet also can allow carb cycling and adjusting according to training sessions, periodisation and performance goals, which keto can’t.

What if you could take the best bits of both approaches to really super-charge your performance?

So which is best?

Although both vegan and keto camps claim to be superior to any other way of eating, neither are the definitive diet to achieve improved performance for every athlete.

Either approach can play a role for specific types of athletes at specific times – with the right preparation and planning.  However you can achieve many health and performance benefits without having to follow any particular ‘labelled’ regime.  In fact the best way to perform at your best is to tailor your nutrition to your unique needs. Sports dietitians work with individual athletes to help them work out the best approach, at the best time, for their individual training and performance goals, considering their philosophical, physiological, psychological and taste needs.

The best strategy for you should include foods that you love, tailored to you, so you can live and perform at your best.

How 'food porn' marketing of health foods misleads us towards temptation

We see them on social media every day - gorgeous food photos, stacked and styled to perfection with delicious looking fresh ingredients. But are these artistic creations of fritters, stacks, smoothies and bowls really good for us? If we are using these beautiful bowls of goodness as inspiration for our daily meals are we doing ourselves a favour or doing more harm than good? 

I am relatively new to Instagram, but I feel more and more concerned about the way nutritious foods are portrayed and promoted. Others share my concerns!  Nina Mills from What's for Eats (an experienced Instagrammer!) has written Why I post food photos on Instagram that is well worth a read and I certainly share many of her sentiments. 

Below are some things to think about as you scroll through your favourite food photos.....

Is that really healthy?

The two health food photos that frustrate me the most are breakfast related – pancakes and smoothie bowls. Although those high protein maple and berry pancakes look amazing and sound super-healthy, if you replicated this at home you may be shocked at the sugar content. Same for smoothie bowls – some of the ingredients may be nutritious, but there is also often a lot of hidden sugars. Nut butters, seeds, dried fruit, coconut, avocado…..all nutritious ingredients but the energy can quickly add up. Natural sugar is still sugar (think maple syrup, rice malt syrup, agave, etc.) and not a more nutritious substitute for table sugar. Your protein bliss balls washed down with a cacao salted caramel smoothie could very well be equivalent to breakfast and lunch put together!  *You can read more about natural sugars in my blog post 'The Great Sugar Con....'

Size matters

Let’s face it, most Instagram serves are not small. Unless you are a 120kg+ rugby player, that plate may not be the best amount for you.  Fine dining portions don't always look as enticing as a platter-sized meal.  Large portions that look tasty can make healthy food more appealing, but the serves depicted are not going to suit everyone. 

Eating well can be boring

I don’t tend to share photos of my daily breakfast. A standard bowl of porridge with yoghurt and fruit/nuts is probably not going to create too much excitement on Instagram. We want to see fun and interesting food that excites our tastebuds!  But as Nina mentions in her post, seeing images of everyday foods can be useful to help us to feel ok when we aren't whipping up exotic dishes three times per day.

To eat well day-to-day, you don’t need to be making corn fritters with avocado salsa every morning. Social media images can create pressure on people to spend hours in the kitchen using expensive ingredients. As much as I hate to say it, healthy eating in most households is not particularly flamboyant, especially as part of a busy lifestyle. Many of us could put in the effort to make our meals a bit more exciting, but we don’t need the extravagance of healthy eating portrayals on social media. 

Social media can provide some great food inspiration, but don’t be blinded by the dazzle and hype. Think about what is in your food, your individual needs and food that makes you feel good - and enjoy an over-the-top over-styled Instagrammable feast now and then!

Six of the best carbohydrate foods to improve your training and performance

Not all carbohydrate foods are equal.  For athletes, it’s not just about eating mounds of rice and pasta.  The quality of your carbs counts.  Smart carb choices can help athletes to feel great and perform at their best.  You can get more nutritional value from your fuel foods with selective choices.  It could be as simple as wild or brown rice sometimes instead of white all the time, or choosing a wholemeal pasta.  Or a wholegrain mix such as the one pictured above. 

Here are 6 of my favourite carbohydrate foods for athletes, to boost nutrition, health and performance.

Sweet potato

Sweet potato is a terrific carbohydrate source for training and energy levels.  Sweet potato has a lower glycemic index than white potato (remembering white potato is still good for you too!).  Sweet potato contains more carbohydrate than white potato, but lower in carbohydrate than rice, pasta, and many other grains (for example, the carbohydrate content of white potato is ~12g/100g cooked, sweet potato ~15g/100g cooked, brown rice ~30g/100g cooked). More benefits - fibre, vitamins such as Vitamins A (beta-carotene) and C, and taste!

Barley

Not a fancy expensive ancient grain, and when you think of barley you may be reminiscing about your grandmother’s lamb and barley soup!  But barley is now back in vogue and for good reason.  Barley is a low GI wholegrain, packed with vitamins, minerals and fibre.  Barley, like oats, contains beta-glucan, a soluble type of fibre applauded for its heart health benefits. 

Super versatile, barley goes well in soups, casseroles, breakfast dishes, cold in salads and great in risottos – there is a great Barley Risotto recipe in my book Eat Right for Your Life.

Sourdough rye bread

If you love to eat bread, make it sourdough.  Research is showing that sourdough bread, although it still contains gluten, can be more easily digested than regular wheat-based breads.  Try to select fresh baked sourdough from a local bakery and experiment with the different varieties to see what works for you – rye or spelt are terrific options for nutrition and low GI energy pre-training.

Bananas

A banana is the perfect portable pre-training snack – just enough carbs to fill that space in your tummy and give you an energy boost for the session ahead.  On their own, or part of a recovery smoothie or fruit/yoghurt/granola mix, bananas are a winner.

Sweetcorn

Sweetcorn is a sneaky source of nutritious carbohydrate, also packed with nutrients and fibre, and a similar carbohydrate content to white potato at ~13g/100g cooked.  Great in salads, soups, main meals or a cob of corn as a snack.

Oats

One of the cheapest and best carb options around are oats.  A small amount goes a long way and can keep your engine running for hours.  Rich in fibre and nutrients, and with a surprising protein content, you can find more detailed info in one of my more popular blog posts Oats vs quinoa for health, energy and performance.

Sorry if I’ve missed your favourite, there are plenty of great carbohydrate-rich foods out there!  Performance isn’t just about carbs though - plan your meals and snacks to meet your day-to-day, training and performance nutrition needs.

Dairy vs soy vs almond vs other milks - how to make the best choice for your nutrition needs

Non-dairy milk options are well and truly mainstream these days. While soy milk has traditionally saved the day for many dairy intolerant individuals as a milk substitute, today there is a wide range of milk choices that allow food and drinks to be enjoyed that may not otherwise be well tolerated.  But while you enjoy your almond or soy milk latte, it’s worth a fleeting thought about the nutrition quality of your milk.  Just because a milk might look the same or be used in the same way, it doesn’t make all milks equal from a nutrition perspective.  There are significant nutrient differences across the various milk options and these are important to consider (in conjunction with our overall nutrient intake from foods).

How do the milks differ?

The nutrition composition of a milk will depend on the source. For plant-based milks, the nutrition composition of the wholefood is not automatically translated to the milk.  For example, almonds are rich in a range of vitamins and minerals and provide protein, however almond milk is far lower in protein and minerals like calcium.   Nut and seed milks usually strain away the nut pulp, where much of the nutrition lies, and are predominantly water.

Small differences in carbohydrate, sugars and fats between the different milks aren’t generally too much of a concern, other than perhaps the higher fat content in some coconut milk products (and small amounts of beneficial omega-3 in some of the plant-based milks), and the higher carbohydrate and glycemic index of rice milk (making it perfect for post-training smoothies or a base for protein powder!).  More important are the differences in the protein and calcium content.

Protein

Most alternative milk options contain little or no protein, and the protein present is often low quality (meaning it is lacking some of the essential amino acids).  Soy milk and pea milk are the exceptions - they have a similar protein content and quality to dairy milk.  Pea milk is made from pea protein isolate, and contains a reasonable level of the amino acid leucine, important for muscle protein synthesis - particularly important if you are using milk in a recovery smoothie or shake after exercise. 

Hemp milk also contains a relatively high quality protein, however the total amount may be on the low side for commercially made products (important to check the labels)! Home-made hemp milk will likely be naturallly higher in protein and other nutrients compared to one you would buy (unless it’s fortified).

If your preference is for a plant-based milk that is low in protein, ensure to add in a high quality protein source eg. try adding a protein powder, almond meal, chia seeds and/or nut butters to a smoothie with an almond milk base. Or try to balance protein intake from food rather than relying on fluids as a source.

Calcium

The other nutrient to look out for is calcium, although many commercial products are now fortified with calcium up to a similar content as dairy milk.  If you choose organic non-dairy milk varieties, these are the ones less likely to be fortified with calcium, a quick check of the label should tell you.

Milk facts and figures per 100ml (based on a selection of brands available in the supermarket, please read the label to determine the specific nutrient content of the brand of milk you use).

*Milk and low-fat milk refer to dairy varieties

Dairy foods are a rich source of high quality protein and calcium - fortified soy and pea milks are your closest equivalent in terms of nutrition. Always check your milk’s nutrition profile and adjust your daily food intake if necessary to fill some of the gaps for protein and calcium. A Sports Dietitian can help you with this if you need some guidance.

We are talking specifically nutrition comparison of milks here, but you may also wish to consider the environmental impact of milk production, with the production of plant-based milks having a lower impact compared to dairy.

Many factors contribute to nutrition choices - taste is a big one too! Your milk choice will depend on your own needs, beliefs, preferences and budget.

Salmon and Ricotta Frittata

Image by Bec Doyle Photography, from the book Eat Right For Your Life, Wilkinson Publishing

Looking for a protein-packed lunch or easy dinner?  Eggs can be prepared in so many ways and this delicious frittata combines the protein from eggs, salmon, cheese and milk to make a filling dish.   The salmon adds healthy omega-3 fats plus calcium, so along with the cheese and milk, this dish will help you to meet your calcium requirements.  If you don't tolerate lactose well, use a lactose-free milk and mix in some tasty cheese instead of the ricotta.  You could also add some leftover roast vegetables, or serve with a delicious big green salad.  Leftover frittata is great for breakfast or snacks the next day too!

Salmon and Ricotta Frittata

Serves 4

 Ingredients:

2 tsp oil

2 spring onions (scallions), sliced

100g/3.5 oz baby spinach leaves

400g/14 oz tin of salmon, drained and flaked

100g/3.5 oz low-fat ricotta cheese, crumbled

6 eggs, whisked

1/3 cup (80ml) low-fat milk

1 tbsp chopped dill

½ cup/50g low-fat cheese, grated

 Method:

1. Heat the oil over a low heat in a non-stick fry pan with a heatproof handle, add the spring onions and spinach and cook until the spinach wilts.  Remove the pan from the heat and add the drained salmon and crumbled ricotta, stir gently so it is evenly spread over the bottom of the pan. 

2. Whisk the eggs lightly, combine with the low-fat milk pour into the pan and continue to heat on low until the eggs are almost cooked, being careful not to burn the base of the frittata.

3. Sprinkle with chopped dill, grated low-fat cheese and salt/pepper to taste then place under a pre-heated grill until the cheese is melted and the frittata is cooked through. Serve with a green salad.

This recipe is from my book Eat Right For Your Life.  If you love healthy recipes, I have a new book due for release later this year also, all about performance nutrition.  Plus don't forget to leave your details here on my blog page so I can send you more recipes and performance nutrition info in the meantime.  You can also follow me on Facebook and Instagram, where I put lots of photos of dishes eaten at home and out and about.
