Losing fat-weight is not seen as a quick, easy process. That is because many people are misted into believing that if they diet, they will lose weight. They will, but it will not be fat-weight-loss but water-weight loss and lean-muscle-weight loss. Only aerobic exercise can build up your lean muscle mass and ensure fat-weight loss.
As you continue to exercise, you may find that your weighing machine sticks stubbornly to one weight. For example, if you were 70 kg when you began exercising, you will still be 70 kg. Don't get disheartened. It does not mean that you are not losing fat. What it means is that your muscles are developing, they are getting stronger and becoming more efficient. It is a temporary but a long drawn-out phase. Your muscles are burning fat.
