Evidence-based articles on weight, written by the Manova editorial team and medically reviewed by our clinical lead. Every article lists the research it is based on.

Why am I not losing weight? 9 reasons the scales stall

Nine reasons, in the order they’re actually likely. Most of them are fixable, a couple need a blood test, and none of them are that you lack willpower.

How much weight can you safely lose in a month?

Two to four kilos, and the first fortnight will flatter you. Here’s what a realistic month looks like, and when losing faster stops being a good idea.

Calorie deficit explained, without obsessing over numbers

The principle is simple and the arithmetic is a liar. Here’s what a calorie deficit really is, and how to use the idea without weighing your cornflakes.

Waist-to-height ratio: the 30-second health check

Illustration of a figure with a tape measure at the waist beside a height bar

One tape measure, one number, thirty seconds. It tells you something BMI can’t, and the target is easy to remember: keep your waist under half your height.

How much protein do you need to lose weight?

Protein is the one thing worth getting right before you fuss about anything else. Here’s how much you actually need, and what that looks like on a plate.

The licence says one thing, the NHS says another, and the two get confused constantly. Here’s who actually qualifies, and what a safe prescriber has to check.

What happens when you stop weight loss medication?

Appetite comes back when the medicine stops. Here’s what the trials found about regain, and why the plan for stopping matters as much as the plan for starting.

Side effects of weight loss medicines: what’s common, what’s rare and when to get help

Illustration of a checklist with coloured markers and an alert symbol

Most of it is your gut adjusting, and it passes. A few things aren’t — here’s how to tell one from the other, and when to ring someone.

Mounjaro vs Wegovy: how do they compare?

Abstract illustration of two overlapping circles

Two weekly injections, endlessly compared and rarely explained properly. Here’s what the trials actually measured, side by side.

What is a healthy BMI in the UK? Ranges, limits and a better measure

Illustration of a tape measure and a colour-coded BMI scale

BMI was never designed to judge one person. It’s still a decent first check — here’s what the UK ranges mean, and the 30-second measurement that tells you more.
