There are 7,700kcals (kcal=calorie) worth of energy in 1kg of fat. That means in order to burn 1kg of fat, you must have a calorie deficit of 7,700. Considering the average daily intake can be anywhere from 1,800-2,400kcals, it takes some time to burn that fat.
According to studies, for every 1 kg of weight loss, 7700 calories are needed, or 1000 calories are lost 0.13 kg. However, reducing calories and combining it with exercise will cause weight loss faster than without exercise.
1kg of fat is 7,700 calories. To lose 1kg of fat, you need to be in a calorie deficit of 7,700 calories.
To lose weight, you must be in a calorie deficit (energy expenditure is greater than energy consumption). To lose a kilo of fat a day, though is ridiculous. It's impossible. Far more advisable is to lose roughly 0.5kg per week - you'll need to be in a ~500 calorie deficit every day.
That's why burning 500 calories per day and eating a balanced diet are recommended. This way, women and men can lose up to 6 kg (13 pounds) and 8 kg (17.6 pounds), respectively (2). Science says you need to burn 3500 calories to lose one pound of fat (3).
A 1200-calorie diet can help you lose weight by keeping you on a structured meal plan. This plan removes the extra calories you might get from snacks and sodas throughout the day. Yet, a diet isn't for everyone. People use this diet to eat fewer calories than they expend through exercise.
But do you really know what's realistic? Over the long term, it's smart to aim for losing 1 to 2 pounds (0.5 to 1 kilogram) a week. Generally to lose 1 to 2 pounds a week, you need to burn 500 to 1,000 calories more than you consume each day, through a lower calorie diet and regular physical activity.
Most people burn around 30-40 calories per 1,000 steps, which means they will burn around 300-400 calories by walking 10,000 steps.
If you place 1kg of muscle on a scale and 1kg of fat on a scale, they will both weigh 1kg. The difference is in total volume. 1 kg of muscle may appear to be the size of baseball whilst 1kg of fat will be three times the size and look like a wobbly bowl of Jelly.
Running. “Running is one of the best calorie burners out there,” Saltos says. An average person can burn anywhere from 500 to 1000 in one hour of running. “Speed, pace, and endurance are all factors that can impact this range.
If you wanted to create the deficit through exercise alone you'd need to burn an extra 1,000 calories a day. That's about 90 minutes of intense exercise a day. And that's more than most people can recover from safely.
You can make a rough estimate of your non-exercise calorie needs based on your age, weight, and sex. For example, a 50-year-old man who's 5'10" tall and weighs 165 pounds may burn about 1,650 calories a day. A 50-year-old woman who's 5' 6" and 135 pounds may burn about 1,400 calories per day.
In order to lose 5kg in a week, you would need to create a calorie deficit of approximately 35,000 calories. This would require burning an additional 5,000 calories per day or cutting 5,000 calories from your diet each day.
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite. Also worth noting is that the human body can adapt.
It depends on your body type and how the fat is distributed. For example I lost about 20 kilos and you can barely tell the difference. That was also because most of weight was in my legs. Then again I would say that people will start noticing around 5 kilos.
Aim for at least 10,000 to 12,000 steps each day which will support a one to two kg weight loss over the course of a week.
If you're not losing weight in a calorie deficit you may need to adjust your stress levels, diet, and sleep patterns. Other reasons for weight gain during a calorie deficit are hormonal changes, aging, and other health conditions.
If 1,200 calories a day is more than 500 calories lower than your weight-maintenance calories, you can expect to lose more than 1 to 2 pounds per week.
