Summer is here—are you paying extra attention to your weight?
In Xiaojiu's group chat, several beauty-conscious friends discussed the topic of "weight" and shared similar concerns:
"I weighed 101 pounds this morning, but by evening it was 105. Did I gain 4 pounds in a day?"
"49kg before eating, 50kg after—I didn't feel like I ate that much..."
Weight fluctuates like waves, unstable and unpredictable, leaving our moods just as unsettled.Why do morning and evening weigh-ins, or weighing on an empty stomach versus after eating, yield different results?
I. What factors influence body weight?
Body weight isn't static. Typically, it rises with age until reaching a peak.As age continues, bodily functions gradually decline, muscles atrophy, and weight begins to decrease. So, what factors influence body weight?
Weight is affected by clothing worn during weighing, diet, fluid intake, sweating, and excretion. For example, weighing yourself on an empty stomach in the morning yields a lower reading than after a meal; in summer, increased sweating means you'll weigh less than in winter under identical conditions.
Under certain circumstances, weight may also fluctuate slightly. For instance, gastrointestinal discomfort or food poisoning can cause symptoms like loss of appetite, nausea, vomiting, and frequent diarrhea, leading to weight loss. For women, hormonal changes during menstruation may cause water retention, resulting in weight gain.
Additionally, medications like antiepileptics, hypoglycemic agents, and glucocorticoids may cause slight weight fluctuations. Some drugs can diminish taste perception, affecting appetite, while others may stimulate appetite.
II. Two Standards for Assessing Healthy Weight
"Weight loss is a lifelong pursuit for women." Some individuals, standing just over 5 feet tall and weighing less than 70 pounds, still obsess over shedding pounds daily. In reality, excessive weight can trigger various health issues, while being too thin is equally detrimental. So how do we determine if our weight is within a healthy range? Two methods exist.
First, check your Body Mass Index (BMI): BMI = Weight (kg) ÷ Height² (m²). According to Chinese standards, healthy adults aged 18-64 should have a BMI between 18.5 and 23.9. A BMI of 24-28 indicates overweight, while ≥28 signifies obesity.
Alternatively, assess your Body Fat Ratio (BFR).The formula for body fat percentage is: Total body fat mass ÷ Total body weight × 100%. For adult women, a normal body fat percentage ranges from 20% to 30%. For adult men, it ranges from 12% to 20%. Athletes have stricter requirements: male athletes typically maintain 7% to 15%, while female athletes generally stay between 12% and 25%.
By measuring these indicators, we can determine whether our weight falls within a healthy range. Weight may fluctuate slightly due to seasonal changes, diet, mood, and other factors—explaining why readings vary across different times and environments.
III. Weighing Yourself This Way Reveals Your True Weight!
So when is the best time to weigh yourself accurately? The answer is first thing in the morning.
After a night's sleep, most excess substances in the body have been metabolized, and residual food has been largely digested. The only factor potentially affecting weight is fecal matter. Therefore, weighing yourself after bowel movements provides the most accurate weight, with minimal influencing factors.
When weighing yourself, avoid carrying any heavy objects and stand still in one spot to prevent distorting the reading.
Some women resist weighing themselves during their period because they notice weight gain! Why is that?During menstruation, fluctuating hormone levels can affect appetite, increasing hunger. Combined with premenstrual water retention and bloating, this can lead to temporary weight gain. However, as long as you maintain a normal diet, your weight will quickly return to normal after your period.
I also want to remind girls not to obsess over their weight. As long as you're within a healthy range, it's perfectly fine to carry a little extra weight.
During weight loss, avoid frequent weigh-ins. First, it may cause anxiety and stress. Second, weight alone doesn't reflect results—you might gain muscle tone, improve body contours, and enhance your figure without the scale showing a drop. That's true progress.
IV. Sudden Weight Loss? Don't Celebrate Yet—It Could Signal 4 Health Issues
Some people experience unexpected weight loss despite not dieting, overeating, or exercising. If this happens to you, hold off on celebrating—it might indicate an underlying health condition!
· Diabetes: When the body can't produce enough insulin, it burns fat and muscle for energy, leading to weight loss.
· Hyperthyroidism: An autoimmune disorder where the thyroid overproduces thyroid hormones. Excess hormones accelerate metabolism, causing the body to burn more energy and leading to weight loss.
· Tumors: Tumor cell growth, reproduction, and spread demand massive energy reserves. They also compete with healthy cells for nutrients, resulting in sudden, severe weight loss.· Depression: Common symptoms include loss of appetite, slowed thinking, and diminished interest in life, increasing risks of malnutrition, cardiovascular disease, diabetes, and tumors.
In a society that glorifies thinness, many young women strive for a "paper-thin waist" or to fit into fashionable clothes. Some resort to daily vegetarian diets, while others go as far as fasting or taking diet pills. But is being thin truly that important? For health, maintaining a standard weight is the right approach.
