You can lose up to five kg in a week by following a calorie-deficit diet, although experts suggest that it's best to try to lose 1 to 2 kg per week. The key is to keep your body in fat-burning mode with a combination of a restrictive diet and increased physical activity. Whether a special occasion is coming up or you just want to feel healthier, sometimes you might want to lose weight quickly. Losing 5 kilograms in a week is a difficult goal to achieve, but you may be able to achieve it with the right diet and exercise strategies.
However, losing weight slowly will make it easier to maintain the weight loss.
