Figures that matter more than the number of pounds. What hides the big circumference of the waist in women and men

The circumference of the waist, the waist-tin ratio, the blood pressure and the blood sugar level offer more accurate indications about the general health than the body weight. The specialists also recommend monitoring the complete lipid profile, the balance between physical activity and sedentary lifestyle, as well as the quality of sleep, for a correct evaluation.

Studies have revealed that there are also obese people, but metabolic health, with a low level of visceral fat, insulin sensitivity and good physical condition.

The paradox of healthy obesity

The concept of healthy metabolic obesity (MHO) describes people with excess weight, but with a normal metabolic profile. An extensive study recently conducted by Swedish researchers on 786 twins, watched for almost 30 years from middle age to old age, showed that about one -fifth of overweight or obese participants have remained healthy metabolic throughout the observation.

This category of people, representing between 10% and 30% of the obesity population, according to the analysis published in the International Journal of Obsity, has distinct biological features. Imaging investigations have shown that they have less visceral and liver fat, considered the most dangerous because they are deposited around the internal organs.

However, researchers point out that MHO often represents a transient stage. Swedish data showed that 59% of healthy metabolic participants at the beginning of the study have developed metabolic syndrome. The risk was 56% higher among obese people compared to normoponderal ones. However, of those initially diagnosed with metabolic syndrome, 60% regained their metabolic health later, without important differences between weight categories.

Here, below, are the figures that matter more than those on the scales, when it comes to health.

1. The circumference of the waist

The circumference of the waist is considered today a more precise indicator of cardiovascular risk than the body mass index (BMI). This measurement better reflects the risk of heart disease than the weight related to height.

Risk thresholds differ depending on sex. In men, values ​​over 94 cm signal increased risk, and over 102 cm indicate a major danger. In women, the corresponding thresholds are 80 cm and 88 cm respectively. Exceeding these limits is associated with a higher risk of diabetes, hypertension and cardiovascular disease.

A 2024 study showed that the accumulation of abdominal fat, reflected by the waist circumference, anticipates the risk of colorectal cancer more than the body mass index.

For an even more accurate assessment, the National Institute for Clinical Excellence (Nice) in the UK recommends calculating the waist-tin ratio. The measurements are made in the same units, then the waist circumference is divided into height. A result below 0.5 indicates a low risk, between 0.5 and 0.59 suggests moderate risk, and over 0.6 signals an increased risk. The basic rule proposed by Nice: the waist should remain under half the height, regardless of sex or ethnic origin, except people with large muscle mass and BMI below 35 kg/m².

2. Blood pressure and blood sugar

The values ​​considered normal for blood pressure are below 120/80 mmHg. Hypertension occurs from 130/80 mmHg and can develop long without visible signs, while producing lesions in the blood vessels, hearts, kidneys and eyes.

Regular monitoring becomes mandatory after the age of 40 years or earlier for people with family risk factors. Untreated hypertension doubles the risk of myocardial infarction and stroke and is the main preventable cause of premature death.

For blood glucose, normal values ​​are below 100 mg/dl before meals and below 140 mg/dl two hours after. Exceeding these limits indicates prediabet or diabetes, conditions that increase cardiovascular risk and accelerate blood vessel degradation.

Maintaining blood glucose in safe limits involves regular physical activity, which increases insulin sensitivity, high fiber diet and low in simple sugars, as well as sufficient sleep for regulating metabolic processes.

3. Lipid profile

The complete analysis of the lipid profile includes several components with different roles. The recommended values ​​for total cholesterol are below 200 mg/dl, but the correct interpretation also requires the detail of fractions.

HDL cholesterol or good cholesterol should exceed 60 mg/dl for optimal cardiovascular protection. LDL cholesterol, responsible for the formation of atherosclerotic plaques, is recommended to be below 100 mg/dl for healthy people and below 70 mg/dl for those with increased cardiovascular risk.

Triglycerides, another type of fat in the blood, reflect the recent consumption of carbohydrates and alcohol. Normal values ​​are below 150 mg/dl. High levels increase the risk of acute pancreatitis and favor the development of atherosclerosis.

The ratio between total cholesterol and HDL provides a more accurate image of cardiovascular risk. A report below 3.5 indicates good cardiovascular protection, between 3.5 and 5 moderate risk, and over 5 signals increased danger.

4. Physical activity

International guidelines set a minimum of 150 minutes of moderate physical activity or 75 minutes of intense exercises. Moderate movement means accelerating heart rate and breathing, but keeping the ability to carry a conversation. Intense activity makes the conversation difficult because of accelerated breathing.

Resistance workouts practiced at least twice a week for all major muscle groups help prevent sarcopenia, ie losing muscle mass associated with aging.

Intense physical activity, however, does not cancel the effects of sedendarism. The state on the seat for more than eight hours a day increases the risk of mortality by 60%, independent of the level of physical activity. Metabolism slows down dramatically after 30 minutes of inactivity, reducing calorie burning and increasing insulin resistance.

The interruption of state periods with short episodes of movement every 30-60 minutes reactivates metabolism and improves circulation. Two minutes of walking or a few easy exercises are sufficient to counteract the negative effects of sedentary lifestyle.

5. Hours of sleep

Adults need seven to nine hours of sleep per night. During this time, the body secretes the growth hormone needed to repair tissues and muscle protein synthesis. The brain eliminates the toxins accumulated during the day, including beta-amyloid associated with Alzheimer's disease.

Sleep deprivation disrupts hormones that regulate appetite. Gerina, hunger hormone, increases by 28% after a night of insufficient sleep, and leptin, the hormone of satiety, decreases by 18%. This hormonal imbalance explains why tired people consume 385 calories more a day, preferring foods high in sugar and fat.

The quality of sleep matters as much as the duration. The fragmented sleep, even if it adds eight hours, does not allow the complete course of deep sleep cycles to restore and strengthen memory. Untreated sleep apnea doubles the risk of hypertension and diabetes.

6. The amount of water consumed

The need for liquids varies from person to person, but for most adults there are between 2.5 and 3.5 liters per day from all sources. Water is the main recommended source, but foods also contribute about 20% of total intake, especially water -rich fruits and vegetables.

Chronic mild dehydration, common in adults, reduces cognitive performance by 10-15% and increases the risk of kidney stones and urinary tract infections. The color of the urine is a simple indicator of the hydration: pale yellow indicates adequate hydration, and dark yellow signals the need to increase the consumption of liquids.

A glass of water before the meal can reduce the caloric intake by approximately 75–90 calories at each meal, favoring a weight loss of 2-3 kilograms in a few months, without other food changes.

7. The daily portions of fruit and vegetables

The current recommendations indicate a daily intake of about 300 g of fruit for men and adults under 30, respectively 200–250 g for women over 30 years. A standard portion (150 g) means, for example, a medium apple, a large banana, eight large strawberries or 30 g of dried fruits.

Vegetables should reach 350–400 g per day, distributed in several portions and as varied to cover the complete nutrient spectrum. Green leafy vegetables provide folic acid and vitamin K, orange and red bring carotenoids and vitamin C, and cruciferous ones contain sulfur compounds with demonstrated anticancer effects.

However, the preparation mode influences the nutrient content. Steam cooking retains about 80% of the amount of vitamin C, compared to 50% by boiling. The consumption of raw vegetables ensures a maximum supply of enzymes and heat sensitive vitamins, while cooking increases the bioavailability of compounds such as lycopene in tomatoes.

8. Alcohol and smoking

More recently, the World Health Organization (WHO) states that there is no amount of alcohol considered completely safe for consumption. However, for people who fail to eliminate alcoholic beverages, specialists recommend limiting consumption to at most one standard drink per day for women and two for men. A standard drink contains about 14 grams of pure alcohol, the equivalent of 350 ml of beer, 150 ml of wine or 45 ml of spirits.

Smoking remains the main preventable cause of death, causing more victims than HIV, illegal drugs, alcohol, road accidents and armed violence. Even occasional smoking (under five cigarettes a day) doubles the risk of cardiovascular disease.

Summary quitting brings immediate benefits. After 20 minutes, blood pressure and pulse return to normal. After 12 hours, the level of carbon monoxide in the blood is normalized. After a year, the risk of coronary heart disease decreases. After 15 years, the risk is the same as a non -smoker.
