Most of us know our shoe size. We know how much fuel costs. We can tell you exactly how much a bag of rice has gone up.

But ask someone when they last checked their blood pressure, blood sugar or waist measurement, and the answer is often less certain.

That’s worth changing.

Because some of the most important changes in your metabolic health can happen long before you feel unwell.

And the good news is that understanding your risks gives you a chance to do something about them.

1.Your stomach can tell you something your weighing scale cannot

Two people can weigh exactly 90kg and have very different health risks.

Why?

Because where your body stores fat matters.

Fat stored around your internal organs, known as visceral fat, is associated with insulin resistance, type 2 diabetes, high blood pressure and cardiovascular disease.

You can’t tell how much visceral fat you have just by looking in the mirror. But a waist measurement can help show who may benefit from a closer look.

Here’s something you can check in two minutes.

For many adults, a useful starting point is to keep your waist below half your height. NICE, the body that sets health guidance in the UK, gives the same rule of thumb: try to keep your waist to less than half your height. [1] If you’re 170cm tall, that means a waist below 85cm.

Two-minute check

Waist-to-height calculator

Measure your waist at the midpoint between your lowest rib and the top of your hip bone, standing relaxed, breathing out normally, with the tape level and snug but not squeezing. [4]

Enter your height and waist to see your result.

Nothing you type on this page is saved or sent anywhere. For adults only, and not suitable during pregnancy.

This is a screening measure, not a diagnosis. Your overall risk also depends on your age, medical history, blood pressure, blood sugar and other factors. NICE uses these bands for adults with a BMI below 35; above that, a conversation with a healthcare professional is the better starting point.

Why should Nigerians pay attention?

Weight-related illness is common in Nigeria, and a lot of it goes unnoticed.

High blood pressure and high blood sugar don’t need you to feel sick before they matter.

Feeling fine is not the same as knowing your numbers are fine.

You can start by checking your blood pressure and asking a qualified healthcare professional whether blood sugar and cholesterol testing would be appropriate.

2.Why your body may be fighting your attempts to lose weight

Have you ever reduced your portions, lost several kilograms, and then found yourself getting hungrier?

That’s not necessarily a lack of discipline.

When you lose weight, your body can respond by increasing hunger signals and reducing the energy it uses. In a widely cited 2011 study of people who had lost weight on a very low-energy diet, several appetite-related hormones were still altered a year later, and the people in the study reported feeling hungrier. [6]

These biological adaptations can make keeping weight off difficult.

That doesn’t mean weight loss is impossible. It means sustainable weight management sometimes requires more than simply being told to eat less.

Genetics, sleep, stress, certain medicines, hormonal conditions and the food around you can all influence your progress too.

If you’ve been trying for years, it may be time to change the strategy rather than simply try harder.

3.You don’t need to divorce Nigerian food

Let’s settle something.

Rice is not automatically the enemy. Neither is yam, plantain, amala, eba or pounded yam.

The challenge is often the overall combination of portions, cooking methods, drinks, snacks and how often we eat.

Consider a familiar lunch: a generous serving of jollof rice, fried plantain, fried chicken and a bottle of soft drink.

Nothing about that meal makes you a bad eater. But if you’re trying to manage your weight, changing the portions, the cooking methods and the drink can make a meaningful difference.

Practical changes worth trying

No single food determines your health. Your overall eating pattern matters far more.

Try it

Build a balanced Nigerian plate

Pick one from each row and see how your plate balances. A useful guide is about half vegetables, a quarter protein and a quarter starch.

Tap something from each row below.

This is a guide to balance, not a diet plan or a calorie count. If you manage diabetes or another condition, follow the advice you’ve been given by your healthcare professional.

4.The health checks worth knowing about

A bathroom scale tells you your weight.

It cannot tell you your blood pressure, blood sugar or cholesterol.

Those measurements matter because excess weight can sit alongside conditions that develop gradually and sometimes without symptoms.

Blood pressure

High blood pressure often has no obvious warning signs. Untreated, it increases the risk of stroke, heart disease and kidney disease.

Blood sugar and HbA1c

Blood sugar testing can help identify diabetes. HbA1c measures your average blood sugar over roughly the previous two to three months.

Cholesterol

Abnormal cholesterol levels can contribute to cardiovascular risk, even when you feel healthy.

Waist circumference

This helps assess central adiposity, which is relevant to metabolic risk.

The useful question isn’t simply, “Am I overweight?”

It’s: “What is happening to my health, and what can I do about it?”

Your numbers

Do you know your numbers?

Tick what you already know. How often to test depends on your age, family history and risks, so a healthcare professional can advise you.

Nothing ticked yet. Pick one to start with.

5.When eating better and exercising aren’t enough

Lifestyle changes remain the foundation of long-term weight management.

They can improve blood pressure, blood sugar, cardiovascular fitness, sleep and quality of life, even without dramatic changes on the scale.

But obesity is a chronic, relapsing medical condition. [2] For some people, lifestyle changes alone do not produce or maintain enough weight loss to meaningfully address their health risks.

That is where medical treatment may become relevant.

What are GLP-1 medicines?

GLP-1 stands for glucagon-like peptide-1, a hormone involved in regulating appetite and blood sugar.

Medicines that act on the GLP-1 pathway can help people feel fuller, reduce hunger and support weight loss.

Some medicines act on more than one hormone pathway. Tirzepatide, for example, acts on both GIP and GLP-1 receptors.

These treatments are different from herbal slimming mixtures, detox teas or unregulated weight-loss products. They have been studied in clinical trials, although they also carry risks and are not suitable for everybody.

How much difference can they make?

In a major clinical trial, adults with obesity, or with overweight and a weight-related complication, who did not have diabetes, took tirzepatide alongside lifestyle support for 72 weeks. [5]

15–21%

average weight loss with tirzepatide, depending on the dose

About 3%

average weight loss in the placebo group

SURMOUNT-1 trial, 72 weeks, all participants also received lifestyle support. This is an average from a controlled trial, not a promise of what any individual will achieve.

That is a substantial result, but treatment effects vary. Side effects, medical history, how well someone tolerates the medicine, whether they keep taking it and long-term follow-up all matter.

Is medication worth considering?

It may be worth discussing with a qualified healthcare professional if:

Medication is not a shortcut around healthy habits. It can be an additional tool that helps eligible people make and sustain changes.

What about safety?

GLP-1-based treatments can cause nausea, vomiting, diarrhoea, constipation and other side effects. Some risks are more serious.

They require checks for reasons someone should not take them, possible interactions with other medicines, your medical history and appropriate monitoring.

Not everyone should use them. They are not appropriate during pregnancy, and planning a pregnancy needs specific advice.

Only use prescription medication obtained through lawful, verified channels, after a proper medical assessment and with a valid prescription.

6.A realistic starting plan

You don’t need to overhaul your entire life on Monday morning.

Start with five things:

  1. Know your numbers. Check your waist, blood pressure and relevant metabolic markers.
  2. Change one daily habit. Replacing a sugary drink or adjusting a regular meal is a reasonable start.
  3. Move consistently. Walking counts. Begin at a level that is safe for you. [3]
  4. Look at the bigger picture. Sleep, stress, medicines and underlying health conditions can all affect weight.
  5. Seek help when appropriate. If you have obesity or related health problems, an assessment with a qualified healthcare professional can help you understand your options.

The objective isn’t to chase the smallest possible number on a scale.

It’s to reduce avoidable health risks and build a way of living that you can sustain.

7.Your next step

Weight management is not one-size-fits-all.

For some people, a few sustainable lifestyle changes make a significant difference. For others, a more structured approach or medical treatment may be appropriate.

The important thing is knowing that there are options, understanding their benefits and limitations, and choosing a safe path based on your individual circumstances.

Start with knowledge. Then decide what support you need.
