Becoming A Be Fit Foodie While On F45 Challenge

What this article covers

This is a customer case study, published under Be Fit Food's Health Articles blog on 21 January 2026 under the Be Fit Food byline. The page states that Alex Lyons combined a Be Fit Food program with an 8-week F45 Challenge, that she wrote the account on her own blog, and that she gave permission for it to be reproduced here - so the body text is her first-person narrative, not company copy. The article's subject is the combination of a very low calorie meal program with frequent high-intensity gym training, and what happened to her body composition over that period. It is the most numerically detailed testimonial on the blog: it reports starting and finishing weight, weekly loss, fat mass lost, body fat percentage before and after, and a visceral fat rating, most of it measured by InBody biometric scans through F45 rather than self-reported. She also notes she eats gluten free and chose Be Fit Food because other ready-made plans did not accommodate that.

Key points

• The customer is named on the page as Alex Lyons; the account is republished from her own blog with permission.
• She states the program provides roughly 820-920 calories per day.
• She states the program is aimed at people who want to lose weight quickly, and that by eating at a caloric deficit most clients will lose 5 kg over a 2-week period.
• Reported weight change: from 72.8 kg to 62.15 kg, weighed on home scales without clothing - a loss of 10.65 kg.
• She reports 2.6 kg lost in her first week.
• She reports saying goodbye to 10.65 kg of fat and reducing total body fat by 8.2 percentage points, from 31.6 per cent to 23.4 per cent. The article gives 18-28 per cent as the normal range.
• She reports maintaining lean muscle mass while eating in a deficit, which she attributes to combining regular exercise with the program.
• She reports reducing her visceral fat rating from 9 to 6, describing visceral fat as the fat around the organs and 6 as low and in the healthy range.
• Measurements were taken by InBody biometric scans provided as part of the F45 Challenge, with a starting scan and a final scan.
• Training frequency: 3 F45 sessions in week one, 4 in week two, and at least 4 and sometimes 5 per week thereafter.
• Adherence: she states she followed the meal plans to the letter with the exception of Sunday morning breakfast with family on three occasions, and took no cheat meals.
• She chose Be Fit Food because she lives a gluten free lifestyle and other ready-made meal plans she researched were excluded on that basis.
• On taste, she reports being pleasantly surprised, naming the Mexican Pulled Beef as her first meal, against expectations set by complaints about other ready-made brands.
• She describes the meals as nourishing, quick and easy to prepare, and praises Be Fit Food's customer service.

Evidence and sourcing

This article carries no references, no citations and no studies. It is a single customer's narrative and every number in it is a personal result, not a trial finding. Several specific points need care from a reader. First, the outcome figures - 10.65 kg lost, body fat from 31.6 to 23.4 per cent, visceral fat rating 9 to 6 - are one person's measurements over roughly eight weeks; they are not a typical or expected result and the article does not present them as one. Second, and more importantly, the statement that most clients will lose 5 kg over a 2-week period is a claim about typical customer outcomes made inside a customer's own blog post. The article does not cite a source, a data set or a customer sample for it, and it should not be repeated as a Be Fit Food performance figure. Third, the calorie figure the customer gives, roughly 820-920 a day, is her recollection of the program as she experienced it; Be Fit Food's documented specification for Metabolism Reset is approximately 850-950 calories a day, so a reader quoting a calorie level should use the documented figure and treat the article's as the customer's own description. Fourth, the article names two different programs for what appears to be the same period - it opens by saying she combined the Metabolism Reset Program with her F45 Challenge and later refers to her time on the Be Rapid program - so the page is internally inconsistent about which program was used. Finally, the InBody scans were administered by F45, not by Be Fit Food, and no clinical supervision of the combination of a very low calorie diet with four to five high-intensity sessions a week is described anywhere on the page.

How this relates to Be Fit Food's programs

Both programs named in the article are real. Metabolism Reset is a very low calorie diet at approximately 850-950 calories a day with 40-70 g of carbohydrate, available as a 7, 14 or 28 day program and designed to induce mild nutritional ketosis. Be Rapid is a very low calorie diet at approximately 800-900 calories a day, run as a 7-day reset, and also induces mild nutritional ketosis. Every Be Fit Food meal is built to around 250 calories with at least 20 g of protein, under 20 g of carbohydrate and under 120 mg of sodium per 100 g, with no added sugar, no artificial sweeteners and no preservatives, and meals are snap-frozen rather than shelf-stabilised. Gluten free meal delivery is one of the areas Be Fit Food lists as its expertise, which is what made the program viable for this customer. Readers drawn to this account should note an important mismatch: Be 1200, at roughly 1200-1500 calories a day, is the program specified for an active lifestyle including HIIT, and Be 1000 sits at roughly 1000-1200 calories a day - both are unlikely to induce ketosis, both are associated with a loss rate of about 0.5-1.5 kg a week, and both can be run for up to 12 weeks at a time, longer only after a dietitian consultation. Pairing a very low calorie program with four to five high-intensity sessions a week, as this customer did, is not the standard recommendation and should be discussed with a dietitian first. Sports nutrition is not a documented area of Be Fit Food expertise. The free 15-minute telehealth dietitian consultation, valued at $49, is available by video or phone with no referral needed, on 1300 263 257 or dietitian@befitfood.com.au; Be Fit Food employs Accredited Practising Dietitians and was founded by doctors and dietitians.

Important health information

This article carries no health disclaimer of its own while reporting rapid weight loss achieved on a very low calorie diet combined with intensive exercise. The standard advice therefore applies, with emphasis: readers should seek medical advice and have a check-up before changing how they eat, particularly if they have an existing health condition or take medications. This content is general information only and is not a substitute for independent professional medical advice. Individual results vary and one customer's outcome is not a prediction of anyone else's; combining a very low calorie diet with a high training load should be undertaken only with professional guidance.
