Assuming both are normal weight and condition, the man will weigh more, as his bones will be thicker and heavier and his muscles more dense.
In general, men have more muscle and heavier bones than women. That means that healthy men usually weigh more than healthy women of the same height.
Males' major sex hormone is testosterone, and females have high levels of estrogen and progesterone in their blood. Scientists agree that these hormones probably play a main role in regulating body weight.
Muscle is denser than fat, and as it is more compact within your body, as you gain muscle mass, you end up looking thinner, no matter your physical weight. So, if you've been doing a lot of strength training lately, it's likely this is the reason that you're looking fantastic but not dropping those numbers.
Since dense muscle tissue takes up less space than fat, it's possible you may weigh the same (or even more) yet appear slimmer than another person with the same weight, a similar height and frame because of the difference in your body composition.”
Hormone levels fluctuate throughout the 28-day menstrual cycle. These changes can affect a person's appetite and may also lead to fluid retention. Both factors can lead to perceived or actual weight gain around the time of a period.
He explained that "muscle is more dense than fat, so an identical volume of it will weigh more than fat." Exercise physiologist Krissi Williford, MS, CPT, of Xcite Fitness, agreed and said even though your muscle mass weighs more than your fat, "it takes up less space, which is why you look leaner and more toned."
It depends on how much you weigh to start with, how active you are, and how much muscle you have. Generally speaking, if someone who is fairly lean and active gains 5-10 pounds of weight, it will be noticeable. If someone who is overweight or obese gains 10-20 pounds of weight, it will also be very noticeable.
To drop a dress (or pant) size typically requires losing between 5 to 7 kilos. It will also result in losing more than seven centimetres from your waist.
It's Harder for Women to Lose Weight — Really
By nature, women tend to have a lower metabolic rate than men. This means your body uses fewer calories (units of energy) to fuel normal body functions like breathing, thinking, and circulating your blood.
On average, women have 6 to 11 percent more body fat than men. Studies show oestrogen reduces a woman's ability to burn energy after eating, resulting in more fat being stored around the body. The likely reason is to prime women for childbearing, the review suggests.
Randy Turner, the manager of the Texas Health Harris Methodist Hospital Fort Worth Fitness Center, said that men tend to lose weight faster than women primarily due to a key physical difference. “In most cases, men have more lean muscle than women, so it's easier for them to lose weight more quickly,” he explained.
For the same body mass index (BMI), women typically present with ~10% higher body fat compared to men [19,20].
Results. Body Mass Index (BMI) based-obesity is more prevalent among older women than men (26.3% vs. 17.6%). Similarly, higher proportion of older women was at high-risk waist circumference (37.1% vs 8.9%) and waist-hip ratio (78.5 vs 75.4%) than men respectively.
When it comes to body fat, testosterone is a major player in how many calories you burn, how your body utilizes energy, and how your body distributes fat. Men have much higher testosterone levels than women, making it naturally easier to lose body fat, especially in problems areas like the belly.
There are a total of 7700 calories in 1 kilogram of body fat. Losing 1 kg per week is a sustainable goal that you can achieve by creating a calorie deficit. You can do so by cutting down on your calorie intake and exercising routinely.
According to our experts, the reason you gain weight so rapidly in your midsection and not in, say, your calves and forearms is because the adipocytes (or fat cells), which are found throughout the body, are more plentiful in the hips, butt, stomach, and thigh area for women and stomach for men.
As a general rule of thumb, you will need at least 3-4 weeks to drop 3-5kg and up to three months to lose 10kg. This means that focusing on your diet and exercise goals for a couple of weeks without distraction and excess calories will go a long way at getting your weight loss efforts off to the right start.
Losing even just 10% of total body weight (12kg if you weigh 120kg), has been shown to reduce your risk of heart disease. Even in sufferers of heart disease, weight loss has been shown to greatly improve their condition with atrial fibrillation incidence falling by 50%.
Researchers discovered how we gain impressions and perceptions about our own body weight. The mind blends observations made by peers and our own perception of our body to form how we think about our own weight. But that impression can be distorted, allowing us to think that we're thinner than we actually are.
You've gained muscle.
So as you gain more muscle and lose fat, you change your overall body composition, which can result in a higher weight, but a smaller figure and better health. If the scale has inched up, but your waistline hasn't and you feel strong overall, don't sweat the pounds; they're increasing your power.
