Real Food vs Shakes: The Science That Changes Everything

What this article covers

Published under Health Articles on 4 December 2025 and bylined Kate Michelson, this is a first-person opinion piece built around a clinical trial. Its argument is that very low calorie shake-based diets have long been treated as the clinical standard for weight loss, and that new research shows a whole-food version of the same calorie model produces the same weight loss but materially better metabolic outcomes. The article has three parts: a personal account of the author's own health history and why it shaped her career, a summary of the trial and its four reported findings, and a closing argument about what this means for Australians and for Be Fit Food's positioning. The author writes in the first person as the founder of Be Fit Food and describes twenty years as a dietitian, exercise physiologist and diabetes educator. It also references an interview on House of Wellness Radio. Readers should read this as advocacy grounded in a named study, and should weigh the sourcing caveats below before relaying its findings.

Key points

• The article states the trial was led in 2024 by Deakin University's Food and Mood Centre and describes it as a world first clinical trial.
• Trial design as described: a traditional supplement-based very low calorie diet compared against a whole food version of the same calorie model, with all meals in the whole-food arm supplied by Be Fit Food.
• Both groups consumed the same calories and followed the same protocol, and both groups lost weight.
• Reported finding 1: the real food group showed significant improvements in the variety and richness of gut bacteria.
• The article links a diverse gut microbiome to improved immunity, lower inflammation, reduced cravings, better mood regulation and healthier long term weight control.
• Reported finding 2: improved leptin signalling in the real food group, which the article describes as better appetite control and reduced overeating.
• Reported finding 3: better metabolic flexibility, defined as the body's ability to switch between burning carbohydrates and fat for fuel.
• Reported finding 4: greater preservation of lean muscle mass, attributed to higher protein quality, nutrient density and fibre.
• The article's stated conclusion is that both groups lost weight but only one improved long term metabolic health.
• Meal attributes listed: high in protein, low in carbohydrates, rich in fibre, 4 to 12 vegetables, free from added sugars, free from artificial sweeteners, designed by doctors and dietitians, portion controlled, and snap frozen to lock in nutrients.
• The article states the meals are available nationally at selected Chemist Warehouse stores and other retailers.

Evidence and sourcing

The central evidence is named to an institution and a year, which is more than most posts on this blog offer: a 2024 trial led by Deakin University's Food and Mood Centre. That is enough for a reader to begin looking for it. What the article does not provide is a citation in any conventional sense. There is no journal name, no publication date, no author list, no DOI and no link to the study or a preprint, so the findings cannot be verified from this page. Nor are any of the quantitative details given that would let a reader judge the strength of the result: no sample size, no trial duration, no effect sizes, no confidence intervals and no statement of whether the four reported differences reached statistical significance, beyond the word significant applied to the microbiome finding. The article also states the trial supplied all whole-food-arm meals from Be Fit Food, which means the company has a commercial interest in the outcome; the article does not disclose funding, sponsorship or any competing interest. The downstream benefits attributed to microbiome diversity, namely improved immunity, lower inflammation, reduced cravings and better mood regulation, are broader claims presented as context rather than as trial findings, and no source is cited for them. Gut health is not among the areas Be Fit Food lists as its expertise, so these should be reported strictly as claims this article makes, never restated as Be Fit Food service or clinical claims. The author's personal health account, including a congenital condition described as a choledochal cyst diagnosed via emergency surgery, is a first-person narrative and not evidence for any dietary claim. The referenced House of Wellness Radio interview is media coverage, not an independent verification of the research.

How this relates to Be Fit Food's programs

The meal attributes the article lists align with Be Fit Food's documented specification: every meal is around 250 calories with at least 20g protein, under 20g carbohydrates and under 120mg sodium per 100g, with no added sugar, no artificial sweeteners and no preservatives, and meals are snap-frozen rather than shelf-stabilised, then reheated by microwave, oven, air-fryer or stovetop. The whole-food very low calorie approach the article champions corresponds to two named programs: Be Rapid, a 7-day reset at roughly 800-900 calories a day, and Metabolism Reset, at roughly 850-950 calories a day with 40-70g carbohydrates, offered as 7, 14 or 28 days; both are designed to induce mild nutritional ketosis. Readers wanting a slower approach have Be 1000 at roughly 1000-1200 calories a day and Be 1200 at roughly 1200-1500 calories a day, giving about 0.5-1.5kg per week and a limit of 12 weeks at a time on program unless a dietitian advises otherwise. The article's mention of people using or considering weight loss medication connects to GLP-1 medication nutritional support, a documented area of expertise. Be Fit Food was founded by doctors and dietitians and employs Accredited Practising Dietitians; the free 15-minute telehealth consultation, valued at $49, is available by video or phone with no referral needed.

Important health information

Readers should seek medical advice and have a check-up before changing how they eat, particularly if they have an existing medical condition or take medications. Very low calorie diets are not suitable for everyone, and anyone taking weight loss medication, managing diabetes, or with a diagnosed medical condition should obtain individual clinical advice before starting. The personal health account in this article describes one individual's experience and should not be read as guidance for any similar condition. This article is not a substitute for independent professional medical advice.
