Frequently asked questions

Do “fat burner” supplements work?

Not in the way the category name suggests, and we would rather say so plainly. No ingredient in these products holds an EU-authorised weight-loss claim. Where measurable effects on metabolic rate exist — caffeine is the clearest example — they are small, short-lived and diminish as tolerance develops. Nothing here substitutes for a sustained energy deficit.

What is actually in these products?

Typically caffeine, green tea extract, chilli or capsaicin compounds, chromium and L-carnitine. Chromium is the one with a genuine authorised claim: it contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels. That is a statement about normal metabolic function, not about losing weight.

What do “water loss” products do?

They shift fluid balance temporarily, which changes what the scale says without changing body fat. The weight returns on rehydration. They are used for short-term appearance purposes, and the honest risk is dehydration — particularly combined with hot weather, exercise or restricted intake. They are not a weight-management tool.

Who should avoid these?

Anyone pregnant or breastfeeding, under 18, or managing heart conditions, high blood pressure, anxiety or a thyroid condition. Stimulant content is the main issue: caffeine here adds to coffee, tea and pre-workout, and total intake is what matters. These products also interact with several medications — check with a pharmacist or doctor before starting, not after.

What actually helps with weight management?

A modest, sustainable energy deficit, adequate protein, resistance training to preserve muscle, and enough sleep — short sleep reliably worsens appetite regulation. Slower is more durable than faster. Nothing in this collection replaces any of that, and a dietitian or doctor is better value than a supplement if you want a plan that lasts.

When is this the wrong part of the shop?

If food or weight has started to feel controlling or distressing, if you are using products like these to compensate for eating, or if you are pursuing loss beyond a healthy weight, then this category will not help and may make things harder. That is worth talking to a doctor about — it is a common experience and there is proper support for it.
