1. During the platform period, your consumption and intake reached a balance, so you didn't lose weight. It is suggested to do strength before aerobic exercise, reverse the amount of breakfast and dinner, pay attention to controlling oil, sugar and salt, and consider changing the exercise mode or improving exercise efficiency, such as changing running to swimming or cycling, or increasing the running speed to 8.5 or 9. Generally speaking, during the platform period, you can break the balance between consumption and intake and re-enter the downward channel by increasing the amount of exercise or changing to exercise that you are not familiar with.
Another possibility is that you haven't lost weight, but your figure may be getting better secretly, because you have the strength to practice, and the increase of muscle may offset the decrease of fat, so in general, your weight has not changed, just from the body fat rate. In fact, when you lose weight, don't care too much about weight changes. If you practice your muscles, you can gain weight. At this time, pay more attention to your waist circumference, hip circumference, leg circumference, arm circumference and other dimensions, or make a measurement of body fat rate. If you are a man, it is ideal to lose weight without losing weight.
I hope it helps you.
