To lose 10 pounds in one week, you'll need to burn between 3,500 and 5,000 calories more than you consume each day by restricting your diet to small portions of nutritious yet low-calorie foods, and significantly increasing your aerobic exercise with interval training, sports, and other vigorous activities.
Aim to lose 1 to 2 pounds (0.5 to 1 kilogram) a week over the long term. To do that, you'll need to burn about 500 to 750 calories more than you take in each day. Losing 5% of your current weight may be a good goal to start with. If you weigh 180 pounds (82 kilograms), that's 9 pounds (4 kilograms).
To lose 10 pounds quickly, eat a high-protein, low-carb diet, cut out sugary drinks, and increase physical activity. High-intensity workouts and drinking plenty of water can also help. However, a gradual and steady approach is the best way to maintain long-term results.
Losing 10 pounds in one week is extreme and not recommended for long-term health. It might involve a combination of drastic calorie reduction, high-intensity workouts, and temporary water weight loss, but these methods are often unsustainable and can harm your health.
Safe and sustainable weight loss
Most experts, including the NHS, recommend aiming for 1 to 2 pounds (0.45 to 0.9kg) of weight loss per week. This translates to about: 4 to 8 pounds (1.8 to 3.6kg) per month for most people.
CDC further recommends that you need to lose around 5-10% of your total body weight to notice changes. For instance, if you weigh 170 pounds, you need to lose roughly 8.3-17 pounds to notice a difference.
Losing 5 pounds a week comes to reducing your food intake by 3500 calories over seven days. The value that represents the decrease in calorie intake is known as the calorie deficit.

Best: Water

How much weight you can lose from walking depends on your current weight, diet and activity level. We recommend losing no more than 1 to 2 pounds per week for sustainable weight loss, which means you could potentially lose 5 to 10 pounds in 5 weeks.
A good rule of thumb is that people tend to notice your weight loss when you've lost around 10% of your starting weight, so if you started at 250lbs, people will start to notice when you've lost 25lbs. Naturally, the same amount of weight loss can look different on different people.

Water weight is not usually a cause for concern, but it can be uncomfortable and recurring. Reducing salt and carbohydrate intake, keeping hydrated, and frequently exercising are all good ways to lose water weight and prevent it from returning.
