Obesity is generally defined as having a Body Mass Index (BMI) of 30 or higher, calculated from your weight and height, with categories like Class I (30-34.9), Class II (35-39.9), and Class III/Severe (40+) for increasing severity. While BMI is a standard tool, doctors also consider other factors like waist circumference and ethnic background for a more complete health picture.
A BMI between 25 kg/m² and 29.9 kg/m² is considered overweight. A BMI of 30 kg/m² or higher is considered obese. To check your BMI, type your height and weight into the BMI calculator for adults from the National Institute of Health.
A person who is 5 ft. 10 in. tall is in the overweight range (BMI is 25 to 29) if they weigh between 174 and 202 pounds. They are in the obese range (BMI is 30 or more) if they are 209 pounds or more.
A weight of 70kg can fall within the healthy weight range for various individuals. Height plays a significant role. A shorter individual might find a BMI of 70kg within a healthy range, whereas a taller person could potentially fall into the overweight or even the obesity category using the same metric.
Ozempic is typically recommended for individuals who have a BMI of 30 or higher, which falls into the obese category, or for those with a BMI of 27 or higher who have additional health concerns such as high blood pressure, type 2 diabetes, or high cholesterol.
Some of the most common health risks associated with being 20 pounds overweight include: Increased risk of heart disease: Carrying excess weight can increase your risk for heart disease, which is the leading cause of death in the United States.
Whether 80kg (176 lbs) is "heavy" for a woman depends on her height, body composition (muscle vs. fat), and frame, as Body Mass Index (BMI) can categorize it as overweight or obese for shorter women but might be healthy for taller individuals with significant muscle mass, though a BMI over 30 (obesity) is generally considered unhealthy for most. A single number doesn't define health; factors like fitness level, strength, and body shape matter more than just weight.
Fat loss is generally healthier as it preserves lean muscle mass, which is crucial for metabolism and overall health. Combine regular exercise (like resistance training and cardio) with a balanced, protein-rich diet, adequate hydration, and good sleep.
BMI Categories – What Your Results Mean
If you're 165 cm tall, a healthy weight is between 54 kg and 68 kg. If you weigh over 81 kg, your BMI is above 30, placing you in the obesity range.
For most adults, if your BMI is:
How to get your BMI down
The term of adiposopathy clearly defines the pathogenic role of adipose tissue. Four phenotypes of obesity have been described, based on body fat composition and distribution: (1) normal weight obese; (2) metabolically obese normal weight; (3) metabolically healthy obese; and (4) metabolically unhealthy obese.
Generally used to refer to males who could be overpowered and taken advantaged of by other males who are above 200 pounds. Could also be used as a general statement about a male weighing approximately 140-160 pounds or 60-70 kilograms.” - Urban Dictionary.
A clear definition of morbid obesity is very important because this definition is used to guide doctors in the selection of treatment options for people who are overweight. Individuals are usually considered morbidly obese if their weight is more than 80 to 100 pounds above their ideal body weight.
The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.
Adele's significant weight loss wasn't from a quick fix but a two-year journey combining intense strength training, Pilates, hiking, boxing, and cardio, alongside major lifestyle changes focused on managing anxiety, not restrictive diets like the Sirtfood Diet, with workouts happening multiple times daily for mental and physical strength. Her routine included morning weights, afternoon hikes or boxing, and evening cardio, emphasizing getting stronger, which naturally led to fat loss and improved well-being.
Losing 5kg (about 11 lbs) in two weeks is possible, especially initially due to water loss, but most health experts recommend a safer, sustainable rate of 0.5-1kg per week, as rapid loss can mean losing muscle, not just fat, and may not be healthy long-term. To achieve faster weight loss, focus on a significant calorie deficit through reduced processed carbs, increased protein/fiber, adequate hydration, and regular exercise, but be aware of potential risks like muscle loss and nutritional deficiencies, and consult a doctor.
"Chubby" isn't a medical term, but it generally refers to being in the Overweight BMI category (25.0 - 29.9 kg/m²) or starting to enter the Obese range (30+ kg/m²), though BMI doesn't account for muscle, body fat percentage, or body composition, making it a general guideline for adults. To find your weight in kg, calculate your BMI: Weight (kg) / Height (m)², and use the ranges (Healthy: 18.5-24.9; Overweight: 25-29.9; Obese: 30+) to see where you stand.
No single body part loses fat first. Everyone loses fat from different places initially, depending on a variety of factors. In general, women may lose fat from their legs first, and men may lose fat from their torsos first — but it's highly individual.
