CSIRO Total Wellbeing Diet

The CSIRO Total Wellbeing Diet (TWD) utilises a structured higher protein diet as part of a nutritionally balanced lifestyle programme. Its effectiveness and impact have been the subject of various studies, but let’s take a closer look at how the program works. 

The diet increases protein intake, which has been scientifically shown to enhance satiety more than carbohydrates or fats. A higher protein intake can help reduce overall calorie consumption by making individuals feel fuller for longer periods, thereby aiding in weight loss. Proteins also have a higher thermic effect than other macronutrients, meaning the body uses more energy (calories) to digest protein, which can contribute to weight management.

But that doesn’t mean that TWD is ignoring nutritional balance. TWD incorporates a wide variety of foods to ensure that nutrient requirements are met. This includes adequate intakes of fibre through fruits, vegetables, and whole grains, and healthy fats from sources such as nuts, seeds, and oily fish. This balance is crucial for long-term health and prevention of nutrient deficiencies.

Additionally, The program also includes strategies to support behavioural change towards food and exercise. This involves goal setting, self-monitoring, and developing problem-solving skills to handle dietary challenges and physical activity. Such behavioural strategies are essential for the sustainability of lifestyle changes and long-term weight management success.

A study investigated the impact of the TWD on weight status and well-being in Australia, showing that 80% of TWD purchasers actively used the eating plan. Approximately 3.8% of the sample reported an average self-reported weight loss of 5.7 kg. The study indicates that the TWD might be a successful mechanism for delivering lifestyle advice, with increased awareness of nutrition and well-being among users. 

Additionally, the program may not be suitable for all individuals, particularly those with specific health conditions, dietary restrictions, or preferences (e.g., vegetarians, vegans, or individuals with certain medical conditions). Personalisation of the diet to meet individual health needs and preferences is crucial to minimise risks and ensure nutritional adequacy.

Noom Behavioural Modification Strategy

Noom is a weight loss program that merges technology with psychology to help users develop healthier eating habits and lose weight sustainably. It’s primarily accessed through its mobile app, which combines the functions of a personal health coach, a nutrition database, and a fitness tracker. 

Unlike traditional diet plans that focus solely on the physical aspects of weight loss, such as calorie counting and exercise, Noom incorporates psychological principles to address the underlying habits and thought processes affecting eating behaviours and weight management.

Noom utilises concepts from cognitive behavioural therapy (CBT) to help users understand and alter their relationship with food. By identifying and modifying negative thought patterns and behaviours associated with eating, Noom encourages more mindful and healthier food choices.

The efficacy of the Noom weight loss programme has garnered attention due to its unique approach that combines psychological strategies with nutritional guidance and physical activity to facilitate weight loss and behavioural change. While several studies and user testimonials suggest positive outcomes, understanding both the effectiveness and potential risks is crucial for anyone considering Noom.

A study published in 2023 found that 56% of Noom users reported a decrease in body weight while using the app, with significant proportions of participants losing over 5% of their body weight. The programme’s emphasis on behavioural change, personalised coaching, and self-monitoring through food logging and exercise tracking is credited for its success.

Noom uses a calorie-tracking system which, while it might be effective for weight loss, it can also lead some users to become overly focused on calorie intake. This could potentially lead to an unhealthy relationship with food for some individuals, including those with a history of disordered eating.

From a mental being perspective, the focus on weight loss and constant monitoring of food intake and body weight can have psychological impacts, including stress, anxiety, or an unhealthy focus on body image.

Plant-based Diet

A plant-based diet for weight loss involves consuming foods primarily from plant sources. This includes fruits, vegetables, legumes (beans, lentils, peas), whole grains, nuts, and seeds. The diet minimises or excludes animal products, depending on whether one follows a completely vegan approach or a more flexible plant-based diet that might include occasional animal-derived foods like dairy or eggs.

Scientifically, fibre helps to regulate the digestive system, promote feelings of fullness, reduce calorie intake, and stabilise blood sugar levels. This can lead to natural weight management. Additionally, fruits, vegetables, whole grains, and legumes have a lower caloric density compared to animal-based foods. This means you can eat larger volumes of these foods for fewer calories, which can help in creating a calorie deficit for weight loss without feeling hungry.

A study compared the effectiveness of various plant-based diets (vegan, vegetarian, pesco-vegetarian, semi-vegetarian, and omnivorous) and found that at 6 months, participants on a vegan diet experienced a significantly greater weight loss compared to other groups. This suggests that plant-based diets, particularly vegan diets, can be effective for short-term weight loss and potentially for long-term weight management as well. 

Although there are many health benefits to a plant-based diet, such as: the reduced risk of diabetes type 2 risks, improvement of cardiovascular health, and reduced inflammation in the body, there are still a few health risks that are associated with it. 

Without careful planning, plant-based diets may lead to deficiencies in essential nutrients such as vitamin B12, iron, calcium, vitamin D, and omega-3 fatty acids. It’s important for individuals following plant-based diets to ensure they are obtaining these nutrients through fortified foods or supplements.

Moreover, some individuals might rely heavily on processed plant-based foods, which can be high in added sugars, salt, and unhealthy fats. This can negate the health benefits of a plant-based diet and lead to weight gain and other health issues.

To mitigate these risks, individuals considering a plant-based diet for weight loss should focus on consuming a variety of whole foods, including fruits, vegetables, legumes, whole grains, nuts, and seeds. Consulting with a dietitian or nutritionist can also help ensure nutritional adequacy and achieve optimal health outcomes while following a plant-based diet.


The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is a dietary plan designed to help prevent or reduce high blood pressure (hypertension). Developed in the United States in the early 1990s through research sponsored by the National Institutes of Health, the DASH diet emphasises the intake of fruits, vegetables, whole grains, and lean proteins, while limiting salt, red meat, sweets, and foods containing high amounts of saturated fat.

This diet not only aims to reduce blood pressure but also is considered beneficial for weight management, lowering cholesterol levels, and reducing the risk of diabetes and heart disease. 

A study examining the efficacy of a DASH-type diet in adolescents with elevated blood pressure found that the DASH intervention led to a greater decrease in systolic blood pressure and improvements in diet quality, including increased intake of fruits, potassium, and magnesium, and a decrease in total fat.

Adopting the DASH diet involves making gradual changes to eating habits, such as introducing more vegetables and fruits into meals, choosing whole grains, and being mindful of salt and sugar intake. It’s a flexible and balanced eating plan that can be adapted to meet individual dietary needs and preferences.

However, like any dietary plan, there are considerations and potential risks to be aware of, especially for certain populations or when not implemented correctly. 

While the DASH diet promotes a balanced intake of nutrients, there is a potential risk of nutrient imbalances if the diet is not well planned. For example, the diet emphasises low-fat dairy products, which could lead to insufficient intake of fat-soluble vitamins if not balanced with other sources of fats.

Another potential risk from this diet plan is the sudden increase in dietary fibre through a higher intake of fruits, vegetables, and whole grains. These can cause digestive discomfort for some people, such as bloating or gas, especially if they are not used to high-fibre diets.

Given the limitations in studies specifically focusing on the risks of the DASH diet, individuals considering this dietary plan should consult with healthcare providers or dietitians to ensure it meets their nutritional needs and health conditions. For some people, especially those with hypertension or at risk for cardiovascular diseases, the benefits of the DASH diet may outweigh the potential risks when followed correctly.

Weight Watchers

Weight Watchers, now known as WW, is a commercial weight management program that encourages the adoption of a healthy lifestyle for long-term weight loss and maintenance. The program is designed around a points system, where foods and beverages are assigned specific points based on their nutritional values. Participants are allocated a daily points budget that works similarly to a calorie calculator. 

The efficacy of this weight loss program is still being investigated with some studies advocating towards the  success rate of the program, while several studies assert to the contrary that the Weight Watchers program does not provide significant results compared to other commercial programs. 

A study provided a comprehensive review comparing commercial weight-loss programs, including Weight Watchers, to control/education groups. At 12 months, Weight Watchers participants achieved at least 2.6% greater weight loss than those assigned to control/education, indicating its effectiveness in long-term weight management.

Interestingly, there is a study published in the American Public Health Association highlighting Weight Watchers in people with prediabetes. The study showed that participants in the Weight Watchers program lost significantly more weight at 6 and 12 months compared to those receiving a standard Diabetes Prevention Program-based intervention. This highlights Weight Watchers’ potential in managing weight and related health conditions in a high-risk population.

However, there are considerations and potential risks that participants and healthcare providers should be aware of:

  • Disordered Eating Patterns
    For some individuals, focusing intensely on food tracking and points can potentially contribute to unhealthy attitudes towards food and eating. There’s a risk that this focus could exacerbate or contribute to disordered eating patterns in susceptible individuals.
  • Mental Health Considerations
    The emphasis on weight loss and continuous tracking of food intake and body weight can also have psychological impacts, including stress, anxiety, or an unhealthy focus on body image for some individuals.

For individuals considering WW or any weight loss program, it’s advisable to consult with healthcare providers to ensure the program aligns with their health needs and goals and to address any potential risks or concerns.
