When you're trying to lose weight, it's natural to want it to happen very quickly. But people with gradual and steady weight loss (about 1 to 2 pounds per week) are more likely to keep the weight off.
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.
Quick Weight Loss Doesn't Last
While seeing a quick weight loss is definitely encouraging, it generally doesn't last long-term. Why? Because quick weight loss is often tied to temporary changes in diet or the shedding of water weight. Losing one pound per week means that you're attempting to lose actual fat.
According to many experts, losing 1–2 pounds (0.45–0.9 kg) per week is a healthy and safe rate (1, 2, 3 ). Losing more than that is considered too fast and could put you at risk of many health problems, including muscle loss, gallstones, nutritional deficiencies and a drop in metabolism ( 4 , 6 , 7 , 8 ).
So you'd lose about one pound for every extra 35 miles you walk — provided you don't change anything about your current food intake or other activities. If you walk briskly (at a pace of 4 miles per hour) for 30 minutes on five out of seven days, you'll log 10 miles a week.
Running is the winner for most calories burned per hour. Stationary bicycling, jogging, and swimming are excellent options as well. HIIT exercises are also great for burning calories.
Running at even a slow pace burns a lot of calories for 30 minutes. On average, running burns between 10.8 to 16 calories per minute and putting it at the top of the list of workouts that burn the most calories.
Rapid weight loss diet is a type of diet in which you lose more than 2 pounds (1 kilogram, kg) a week over several weeks.
In general, if you cut about 500 calories a day from your usual diet, you may lose about ½ to 1 pound a week.
Generally, most health experts recommend aiming for about 1–3 pounds (0.5–1.4 kg) of weight loss per week, or approximately 1% of your total body weight ( 33 , 34 ). Therefore, it may take anywhere from a few weeks to several months to lose 30 pounds safely.
Your slower metabolism will slow your weight loss, even if you eat the same number of calories that helped you lose weight. When the calories you burn equal the calories you eat, you reach a plateau. To lose more weight, you need to either increase your physical activity or decrease the calories you eat.
Drinking Water Can Make You Burn More Calories
Drinking water increases the amount of calories you burn, which is known as resting energy expenditure ( 4 ). In adults, resting energy expenditure has been shown to increase by 24–30% within 10 minutes of drinking water.
Reduce the amount of calories you take in (eat less) by 500 calories per day, Increase your physical activity (calorie expenditures) by 500 calories per day, OR. Do any combination of the two to add up to 500 calories.
But many health care providers agree that a medical evaluation is called for if you lose more than 5% of your weight in 6 to 12 months, especially if you're an older adult. For example, a 5% weight loss in someone who is 160 pounds (72 kilograms) is 8 pounds (3.6 kilograms).
You should consult your physician if you have lost more than 5 percent of body weight or 10 pounds without trying in a period of 6 to 12 months. This is especially important if you have other symptoms, too.
In terms of how your body looks, “it usually takes 4 weeks for your friends to notice weight loss, and 6–8 weeks for you to notice,” says Ramsey Bergeron, a certified personal trainer. “Your friends who don't see you every day are much more likely to see a change than someone you're around all the time,” he adds.
Excess visceral fat can pose serious health risks, but when you embark on a healthy diet and exercise plan, this fat is often the first to disappear. This means you're likely to notice weight loss in your abdominal area first. Too much visceral fat can make your belly protrude.
Cardio work, strength training and counting calories and macronutrients (protein, carbs and fat) are the three big components of weight loss. You should be doing all three, but each of these is not created equally when you're trying to lose weight.
