You can lose even more up to five kg in a week by following a calorie deficit diet, although experts suggest that it is better to aim to lose 1-2 kg per week. The key is to keep the body in fat-burning mode with the combination of restrictive eating and increased physical activity. While diet is crucial for losing body fat, you can't avoid the fact that exercise plays a huge role. Maintaining a calorie deficit is essential for any fat loss plan.
To lose 5 kg in five weeks, you will need a deficit close to 1000 kcal. As a reference, a (recently) active man of 90 kg can expect to burn about 3000 kcal per day. Hospitals have also adopted similar meal plans to help their patients lose weight before undergoing major surgery. Whether a special occasion is coming up or you just want to feel healthier, sometimes you want to lose weight quickly. It is claimed that following the diet can cause you to lose just under 5 kg in a week, and if you stick to food intake of 1500 calories a day for a whole month, you could lose up to 13 kg.
Obviously, a lot of that will be water weight; any diet plan that says it can help you lose 10 pounds of body fat in a week is lying or is it extremely irresponsible. The fact is, you're reducing your total calorie intake by including a time-restricted diet, which helps you lose weight quickly.
