Extreme Diet vs. Sustainable Change
Fad diets, why they don't work and nutrition choices you can make in 2024 that aren't extreme.
This article will take it back to basics and highlight 3 healthy, evidence-based nutritional considerations for 2024; with a focus on what you can add to your diet rather than a list of things to avoid or limit.
At this time of year, many people reflect on their health and happiness and think about whether they want to focus on any specific goals or changes. But it can be confusing to decide on nutrition-related goals as there are a lot of faddy, extreme and restrictive approaches out there.
Consuming a good amount and variety of plants is linked with improved gut and heart health, as well as a lower risk of type 2 diabetes (1, 2, 3).
Prioritising plants doesn’t mean that you need to switch to a fully vegan or vegetarian diet. In fact, a famous study from 2018 found that consuming a bigger variety of plants was better for gut health than a vegan diet (next ref). Specifically, participants who consumed more than 30 types of plants per week were found to have healthier, more diverse gut microbiomes, versus those consuming less than 10 types of plants per week (3).
One of the main reasons why plant-based foods are so beneficial is the fibre they provide (along with other nutrients like plant proteins, vitamins, minerals, phytonutrients, carbohydrates and energy). Although fibre is wonderful for the gut, and overall health, a sudden increase can lead to gut issues like pain, gas, bloating, diarrhoea or constipation. So any increase in plant foods and fibre should be done gradually and you should also ensure you are well hydrated — as dehydration plus a lot of fibre can be a recipe for constipation.
Here are some practical ideas for increasing plant diversity:
Eating enough protein is crucial for various bodily functions, including muscle repair, the immune system, bone and skin health, the production of enzymes and hormones and more. Hence why a low intake of protein is linked with muscle wasting, poor bone health, frailty in older age and even a shorter life (4). Due to protein’s central role in muscle repair and function, this nutrient becomes even more of a priority for athletes, those who strength train, older adults and those suffering from critical illness due to an increase in protein requirements.
Good sources of protein include:
There are also a lot of products labelled as high-protein available in shops at the moment, from cereal bars to dairy products and bagels. Although a protein bar or high-protein yoghurt can be a convenient way of boosting your protein intake as a snack, some of these products can be deceiving. This is because although they are technically ‘high protein’ per 100g, they don't always contain much more protein per serving (especially the bread and bagels) and they are also usually more expensive.
Due to the way protein is absorbed and used by the body, it’s most beneficial to spread this across the day (i.e. roughly 20-40g of protein every 3-4 hours) (5). However, most people don’t need to specifically count or track their protein intake, as this can be onerous and bad for your relationship with food. Instead, you can aim for a high protein food with every meal and some snacks.
Consuming a variety of protein sources leads to a greater intake of overall nutrients and amino acids. Diversifying protein intake is especially important for those who follow a plant-based diet as many plant-based sources of protein don’t contain all 9 essential amino acids in an easy-to-digest form.
Focusing on consuming enough protein certainly shouldn’t become an obsessive focus at the expense of overall balance and a healthy relationship with food. But if you feel that you may not be consuming enough protein, here are some tasty meal and snack ideas that contain a good amount of protein (portion sizes aren’t included as this varies based on your needs, it’s usually best to follow your hunger/fullness cues or seek individual advice with this as needed).

Ensuring that you're properly fuelled and eating enough energy may sound basic, but it’s an essential step that many people don’t achieve. This can occur for several reasons like being busy and forgetting to eat enough, dieting, disordered eating, or not properly fuelling for exercise.
Not consuming enough energy can lead to a number of issues including :
The first step is eating regularly during the day in order to provide a steady supply of energy and nutrients. This is individual based on your needs, but in general eating every 2-4 hours, including 3 meals and a few snacks over the day works well for many people.
Ensuring that meals contain a mix of carbohydrates, proteins and fats is also important. Restricting carbs and fats (and consuming a lot of diet foods) is common in those who don’t consume enough energy. Including a variety of carby foods is also a good idea.
Higher fibre options like oats, wholegrain bread and pasta release energy in a more sustained way as well as benefiting the gut and overall health as discussed above. But more refined sources of carbs like white bread, white pasta and sugary foods and drinks also have a place for increasing overall energy intake, providing a quick energy boost and for taste and satisfaction.
Portion size is another individual factor when it comes to consuming enough energy. Being guided by your hunger and fullness signals is a great approach, but it can take time and relearning to get to that place if you have a history of restricting food or dieting. If in doubt, especially if you have additional nutritional needs (e.g. due to training or a medical condition) it’s best to seek individual advice from a Dietitian or Registered Nutritionist.
