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.
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.
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.
A kilogram of fat requires a deficit of 7700 calories (kcal) (Source). Assuming you eat your daily calorie budget for weight maintenance, you'll need to walk a total distance of 73-102 miles (117-164 km) at a moderate pace of 2.5 mph (4 km/h).
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.
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.
Number of calories needed to burn to lose 1kg
0.5kg of fat accounts for about 3,500 calories of energy. That means if you want to lose 1kg a week (a healthy and sustainable amount, although no more than this should be shot), you'll need to create a 7,700-calorie deficit over the course of a week.
Generally speaking, weight loss of 0.5kg - 1kg per week from diet and exercise is a safe and achievable target. Now you know how many days it'll take to lose 1kg, you can extrapolate to get an estimate of how long it could take you to lose any other kg target you have in mind.
The amount of calories required to walk 1 Km equals the weight in Kg (walker of 80 Kg will burn 80 Kcal/Km). Calorie burn depends on body weight, walking speed and time.
That's why it has to be a combination of both diet adjustement and increased activity. 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.
Thus, it generally takes 13,000–16,000 steps to burn 500 calories (kcal). The above range is based on average-weight men taking 13,250 steps and average-weight females taking 15,750 steps daily. Your weight, speed, gender, and age will all affect how many steps you take.
You only burn 30-40 calories for every 1,000 steps you take, so you'd have to get 33,000 steps each day to burn 1,000 calories from walking alone. It's extremely difficult to do that unless you have an active job. Fortunately, research shows that getting 8,000 steps per day is enough to improve your health.
Physical activity, such as walking, is important for weight control because it helps you burn calories. If you add 30 minutes of brisk walking to your daily routine, you could burn about 150 more calories a day. Of course, the more you walk and the quicker your pace, the more calories you'll burn.
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 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.
You will lose up to 10 pounds (4.5 kgs) if you consume 800 calories and exercise regularly. Make sure your doctor or nutritionist is aware of your diet pattern.
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.
So, if you're eating 1,200 calories and not losing weight, it could be that your body is really struggling to function on so little fuel and your metabolism is not functioning well enough to respond to a deficit in the way you'd like.
In addition, consuming as few as 800 calories daily may not give you the energy you need for daily living and regular physical activity, especially if you eat the same foods every day. Talk to your doctor or dietitian to make sure you get the nutrients you need while on a very low-calorie diet.
When a person adds these fat-burning foods to the diet, they can burn fat and lose weight over time. Such fat-burning foods include eggs, nuts, and oily fish. The term “fat-burning foods” may apply to those that produce fat loss by stimulating metabolism, reducing appetite, or reducing overall food intake.
Some people may choose to restrict their daily intake to 1,500 calories. While factors such as age, gender, and activity level can cause caloric needs to vary, a 1,500-calorie intake is typically less than the average person requires. As a result, this diet may help some people lose weight.
