To lose weight, it should be more appropriate to eat full than to eat full. However, you also said that you only consume 1300 calories a day, accompanied by the feeling of whole body muscle trembling. It gives me the feeling that your blood sugar is low.

Of course, you can't know your gender, height and weight from your current problems. It is also impossible to calculate your approximate basal metabolic rate and give a more reasonable opinion.

However, one thing is certain. We must lose weight on the premise of health. Otherwise, it's meaningless. 1300 calories may not even be enough for basic metabolism, which is a bit hasty.

Perhaps it has been some time since you implemented the measure of eating only 1300 calories a day. Now you have symptoms of hypoglycemia, including whole body muscle trembling (I guess you may still have nausea). Prove that this method of dieting and losing weight has endangered your health. You should stop for a while and make plans after you recover. Can't rush for success!

At the same time, it is reminded that to lose weight, we must first ensure total nutrition, and then cooperate with proper dieting and exercise to have good results and ensure our own health.
