It is very useful to drink a large glass of water on an empty stomach and eat nothing before getting up every morning (some people drink light salt water or Pu 'er tea or honey water).

Also, keep exercising. You don't have to do strenuous exercise, you can take a walk, but you have to have time to make sure you feel sporty. Constipation will be better.

Unless necessary, you must not use drugs to solve constipation, because it will produce dependence.

I used to get up early with a glass of water every day and then go jogging.

The weight loss is obvious and there is no constipation problem. o(∩_∩)o~
