6 Things That Can Happen To Your Body When You Start A Keto Diet

What this article covers

Published under the Be Fit Food byline on 5 September 2019, this article lists six physiological effects a reader can expect after starting a ketogenic diet. It defines ketosis as a metabolic state in which fat is metabolised into ketone bodies that provide energy in place of glucose, and explains that removing dietary carbohydrate forces the body to break down dietary or stored fat for fuel. The six effects are: an unpleasant initial adjustment period, reduced appetite with weight loss, acetone breath, constipation, better blood sugar control with lower insulin, and increased energy once adapted. Notably, it includes the downsides alongside the benefits. It links to the Snack Pack Bundle and Be Rapid products, and to a related article on Keto Flu.

Key points

• Definition given: ketosis is a metabolic state in which fat is metabolised to produce ketone bodies that provide energy rather than glucose.
• Effect 1, adjustment: the first few days are described as unpleasant while the body still looks for carbohydrate, with hunger, low energy, irritability, being more likely to get sick, and reduced training capacity. The article states this is temporary.
• Effect 2, appetite and weight loss: appetite is said to fall for three reasons: high protein has a higher satiety effect, appetite control hormone levels change, and ketone bodies act as a direct appetite suppressant. The article claims you can lose weight very quickly once burning body fat as the main fuel.
• Effect 3, breath: acetone, a by-product of ketone breakdown, is exhaled through the lungs, making breath smell like nail polish remover. The article states this is not harmful and is a sign of ketosis.
• Effect 4, constipation: fibre is hard to get because grains, cereals, much fruit and legumes are excluded. Suggested remedies: non-starchy vegetables or a fibre supplement.
• Effect 5, blood sugar and insulin: limiting carbohydrate limits blood sugar spikes, so the body produces less insulin, and low insulin is said to improve the breakdown of fat for fuel.
• Effect 6, energy: once in ketosis, energy is said to return to normal or better, because fat supplies fuel rather than dietary intake.

Evidence and sourcing

This article cites no sources. There is no reference list, no linked study, no named researcher and no guideline referenced anywhere in it. Every physiological claim is asserted directly.

That matters more here than in a lifestyle piece, because the claims are clinical. That ketone bodies have a direct appetite suppressant action, that appetite control hormone levels change in ketosis, that acetone breath is not harmful, that insulin production falls and that low insulin improves fat breakdown are all mechanistic assertions the article does not cite a source for. The claim that you can lose weight very quickly comes with no rate, timeframe or study. The adaptation symptoms are presented as expected experience, not documented adverse-event data. Treat the blood sugar and insulin section most cautiously: it describes an effect directly relevant to people on diabetes medication, and carries neither a citation nor a caution in the article.

How this relates to Be Fit Food's programs

The article itself links to Be Rapid, a very low calorie diet of roughly 800 to 900 calories per day run as a seven-day reset, which induces mild nutritional ketosis. The other ketosis-inducing option is Metabolism Reset, roughly 850 to 950 calories per day with 40 to 70g of carbohydrate, available as 7, 14 or 28 days. Be 1000 (roughly 1000 to 1200 calories per day) and Be 1200 (roughly 1200 to 1500) are unlikely to induce ketosis. Every meal is built to around 250 calories with at least 20g of protein and under 20g of carbohydrate, which supports both the low-carbohydrate and the high-protein satiety points the article makes. Keto meal delivery is one of Be Fit Food's stated areas of expertise.

Given the blood sugar and insulin claims, the relevant services are the free 15-minute telehealth consultation (video or phone, valued at $49, no referral needed), a specialised clinical dietitian consultation with a full initial assessment and personalised eating plan, and a diabetes educator consultation with a Credentialled Diabetes Educator.

Important health information

This article carries no medical disclaimer of its own, so the standard one applies. Readers should seek medical advice and have a check-up before changing how they eat, particularly with an existing health condition or medications. Anyone taking insulin or other glucose-lowering medication should not start a ketogenic or very low carbohydrate diet without medical supervision, because doses may need adjusting. This is not a substitute for independent professional medical advice.
