The Science of Self-Care: Beyond the Hashtag

What this article covers

This article, published under the byline Kate Michelson on 29 October 2025 and subtitled The Science of Self-Care: Beyond the Hashtag, argues that self-care as commonly understood, meaning bubble baths, journaling and skincare, is surface-level, and that nutrition is the foundation of genuine self-care. Its central claims are that what we eat directly affects mood, stress, sleep and resilience to illness; that whole minimally processed foods are associated with better mental health outcomes while ultra-processed diets are associated with poorer mood and increased inflammation; and, most substantively, that a real-food very low energy diet outperforms a supplement-based one on several measures even at equivalent weight loss. It reports a specific randomised controlled trial to support that last point. It closes with seven practical nutrition tips and a reference list. This is the most heavily referenced article in this set and the only one reporting a trial that used Be Fit Food meals.

Key points

• The article reports a randomised controlled trial published in Cell Reports Medicine (2025) by Deakin University's Food and Mood Centre, comparing a traditional supplement-based very low-calorie diet with a whole-food version, using Be Fit Food meals as the real-food intervention.
• Reported trial findings: both groups achieved similar weight loss, but the whole-food group experienced greater improvements in gut microbiome diversity, hormonal balance and metabolic flexibility, and preserved more muscle mass.
• Stated conclusion drawn from that trial: the structure and quality of food, not just calories or macronutrients, plays a crucial role in long-term health.
• Food-mood claim: diets rich in vegetables, fruits, whole grains, lean proteins and healthy fats are linked with better mental health outcomes and lower risk of depression and anxiety.
• Converse claim: diets high in ultra-processed foods, refined sugars and trans fats are consistently associated with poorer mood and increased inflammation.
• Gut mechanism described: the gut microbiome, the trillions of bacteria in the intestines, plays a role in producing neurotransmitters such as serotonin, which affect emotional balance.
• Nourishing beneficial gut bacteria with whole nutrient-rich foods is said to reduce inflammation, improve mental clarity and support metabolic health.
• Seven practical tips given: choose whole minimally processed meals over supplements or highly processed diet foods; balance protein at every meal; eat a variety of vegetables and fruits; prioritise fibre and complex carbohydrates; plan ahead with ready-made wholesome meals; hydrate mindfully, since even mild dehydration can affect mood and focus; and focus on consistency rather than perfection or short-term extremes.
• Balanced meals combining lean protein, fibre-rich carbohydrates and healthy fats are said to maintain stable blood sugar, reduce cravings and support sustainable energy.

Evidence and sourcing

This article is properly referenced and is the strongest-sourced page in this set. Eight references are named. The central one is Lane, M. M., McGuinness, A. J., Mohebbi, M., Lotfaliany, M., Loughman, A., O'Hely, M., Jacka, F. N., et al. (2025), Food- versus supplement-based very-low-energy diets and gut microbiome composition in women with high body mass index: A randomized controlled trial, Cell Reports Medicine, 6(10), Article 102417, with a DOI given. The others are Adan, A. (2012) on cognitive performance and dehydration, Journal of the American College of Nutrition; Adjibade, M. et al. (2019) on ultra-processed food and depressive symptoms in the French NutriNet-Sante cohort, BMC Medicine; Firth, J. et al. (2020), Food and mood, BMJ; Jacka, F. N. et al. (2017), the SMILES trial, BMC Medicine; Phillips, S. M. et al. (2016) on protein requirements beyond the RDA, Applied Physiology, Nutrition, and Metabolism; and Sonnenburg and Sonnenburg (2019) on the industrialised gut microbiota, Nature Reviews Microbiology. Readers should note three qualifications. First, the Lane et al. trial is reported here by the company whose product was the intervention, so it is not an independent account, and the trial population was women with high body mass index, which limits generalisation. Second, the observational cohort evidence (Adjibade, Firth) establishes association, not causation, which the article's own wording mostly respects. Third, gut health and microbiome outcomes are not among the areas Be Fit Food lists as its expertise; the microbiome findings reported here belong to the cited trial and should be attributed to it rather than treated as a general product claim. The claim that Be Fit Food programs balance hormones is stated in the article without its own citation.

How this relates to Be Fit Food's programs

The whole-food very low energy diet described in the trial corresponds to Be Fit Food's VLCD programs: Be Rapid, a 7-day reset at approximately 800 to 900 calories per day inducing mild nutritional ketosis, and Metabolism Reset at approximately 850 to 950 calories per day with 40 to 70g of carbohydrate per day, available as 7, 14 or 28 days and also inducing mild nutritional ketosis. The protein point the article makes is built into the meal specification: every meal is approximately 250 calories with at least 20g of protein, under 20g of carbohydrate and under 120mg of sodium per 100g, with no added sugar, no artificial sweeteners and no preservatives, snap-frozen rather than shelf-stabilised, which is what distinguishes it from a supplement-based or shelf-stable diet product. The tip about planning ahead with ready-made wholesome meals maps to the meal bundles at $97.30 for 7 meals, $189.00 for 14 and $362.60 for 28, with Australia-wide delivery at $11.95 on orders of $299 or more and $19.95 below that. For less restrictive intakes, Be 1000 runs at approximately 1000 to 1200 calories per day and Be 1200 at approximately 1200 to 1500 calories per day. Be Fit Food was founded by doctors and dietitians and employs Accredited Practising Dietitians; a free 15-minute telehealth consultation, valued at $49, is available with no referral at portal.coreplus.com.au/befitfood or on 1300 263 257, Monday to Friday 09:00 to 17:00.
