BMI 28: What It Means & What to Do

BMI 28: What It Means and What You Can Do About It

If your BMI result is 28, you fall within the overweight category (25.0–29.9) according to the World Health Organization. You are not in the obese range, but you are above what is considered a normal weight for your height. This article explains what a BMI of 28 means in practical terms, the health risks it carries, and concrete steps you can take to move toward a healthier range.

Understanding BMI 28 in Context

BMI 28 sits in the upper half of the overweight range. To put it in perspective:

You are 3 BMI points above the top of the normal range (25) and 2 points below the obesity threshold (30). In practical terms, this means you are carrying some excess weight but are still a manageable distance from a healthy BMI.

What Weight Gives a BMI of 28?

Your weight at BMI 28 depends on your height. Here is a reference table:

Health Risks at BMI 28

A BMI of 28 places you in a zone where certain health risks begin to increase, though they are typically lower than those seen at BMI 30+.

Pre-Diabetes Risk

Excess weight, especially around the midsection, reduces insulin sensitivity. A BMI of 28 increases your risk of developing type 2 diabetes by approximately 20–40% compared to someone in the normal range. A fasting glucose test or HbA1c test from your GP can screen for this.

Blood Pressure

Carrying extra weight forces your heart to pump harder to circulate blood through additional tissue. Overweight individuals are 2–3 times more likely to develop hypertension. If you do not know your blood pressure, get it checked — it is free at most pharmacies.

Joint Stress

Every extra kilogram of body weight adds approximately 4 kg of force to the knees during walking. At BMI 28, this translates to meaningful additional stress on the knees, hips, and lower back, increasing the risk of osteoarthritis over time.

Cardiovascular Risk

While not as elevated as at BMI 30+, cardiovascular risk is modestly increased at BMI 28. The Framingham Heart Study data shows that overweight individuals have a 21% higher risk of coronary heart disease compared to those with a normal BMI.

Sleep Quality

Overweight individuals are more likely to experience sleep apnoea and reduced sleep quality, which in turn can make weight management harder by disrupting hunger hormones (ghrelin and leptin).

Who Might Have BMI 28 and Be Healthy?

BMI does not distinguish between muscle mass and fat mass. The following groups may have a BMI of 28 and be in excellent health:

• Athletes and regular gym-goers: Muscle is denser than fat. Someone who strength-trains consistently may carry enough lean mass to push their BMI above 25 without any excess fat.
• Rugby, football, or rowing athletes: These sports require significant muscle mass.
• People with larger body frames: Bone structure varies. A person with a naturally broad build will have a higher BMI at the same body fat percentage.

If you are muscular and active, consider supplementary assessments: body fat percentage (our body fat calculator can help), waist circumference, and blood work are all more informative than BMI alone.

How to Move from BMI 28 to BMI 25

To reach a normal BMI, you need to reduce your BMI by 3 points. Here is what that looks like at various heights:

At a sustainable weight loss rate of 0.5 kg (1 lb) per week, this takes approximately 16–20 weeks — about 4–5 months.

Calorie Deficit Needed

To lose 0.5 kg per week, you need a daily calorie deficit of approximately 500 kcal. You can achieve this through:

• Diet alone: Reduce intake by 500 kcal/day
• Exercise alone: Burn 500 kcal/day through activity (about 60–75 minutes of brisk walking)
• Combined approach (recommended): Reduce intake by 250 kcal and increase activity to burn 250 kcal

Use our calorie calculator to find your personal maintenance calories and plan your deficit.

Nutrition Changes That Work

You do not need a radical diet overhaul. These evidence-based strategies produce meaningful results:

Protein Prioritisation

Increase protein to 1.6–2.0 g per kg bodyweight. Protein is the most satiating macronutrient, reduces cravings, preserves muscle during weight loss, and has a higher thermic effect (your body burns more energy digesting it).

Volume Eating

Fill half your plate with vegetables and salads. These foods are high in volume and fibre but low in calories, helping you feel full on fewer total calories.

Liquid Calories

Eliminate or reduce sugary drinks, alcohol, juices, and high-calorie coffees. A single daily latte and evening beer can add 400–600 kcal that provide little satiety.

Portion Awareness

Use smaller plates, pre-portion snacks, and avoid eating directly from large packets. Many people at BMI 28 are eating only 200–300 kcal more than they need daily — small portion adjustments are often enough.

Exercise Recommendations

Cardiovascular Exercise

Aim for 150–300 minutes per week of moderate-intensity activity (brisk walking, cycling, swimming). The upper end of this range is associated with greater weight loss.

Resistance Training

Strength training 2–3 times per week preserves lean mass during weight loss, boosts resting metabolic rate, and improves body composition even when the scale moves slowly.

NEAT (Non-Exercise Activity Thermogenesis)

Increase daily movement outside of formal exercise: take the stairs, walk during phone calls, stand at your desk, garden, or do housework energetically. NEAT can account for 200–400 kcal per day.

When to See a GP

Consider booking an appointment if:

• Your waist circumference is above 94 cm (men) or 80 cm (women)
• You have a family history of type 2 diabetes or heart disease
• You experience persistent fatigue, excessive thirst, or frequent urination (diabetes symptoms)
• Previous weight loss attempts have been unsuccessful despite consistent effort
• You suspect a thyroid condition or hormonal imbalance

Your GP can run blood tests, check blood pressure, and refer you to a dietitian or weight management program on the NHS.

Monitoring Beyond BMI

BMI is a useful starting point, but track these additional metrics for a fuller picture:

• Waist circumference: The strongest single predictor of metabolic risk
• Body fat percentage: Use our body fat calculator
• Blood pressure: Aim for below 120/80 mmHg
• Fasting blood glucose: Below 5.6 mmol/L is normal
• Cholesterol panel: Ask your GP for a full lipid profile

Your Action Plan

1. Calculate your BMI with our BMI calculator to confirm your starting point
2. Measure your waist for additional risk context
3. Calculate your calorie needs with our calorie calculator
4. Set a realistic timeline: 4–5 months to reach BMI 25 at 0.5 kg/week
5. Start moving: 30 minutes of brisk walking daily is the simplest first step
6. Track progress fortnightly — both weight and waist measurement
