What means its too soon to tell,whats the aspects? I lost one month just trying to keep self discipline,only last 10 days.
Mercury, ruler of the fifth house of pleasure, applies square to your significator, Saturn. Saturn is very self disciplined, but pleasure is too tempting.
Mercury also has a separating trine to Moon, while Moon is in an exact sextile to Jupiter. Those are the only traditional planets within orb of aspect to Moon, so the only planets that can be at all helpful. Moon itself is in the twelfth house, where it can't act, and in fall in overly disciplined Capricorn.
To me, that says you're going too far with your attempts at self discipline, making yourself feel so deprived that you can't sustain it. For a diet to work, it has to allow you to eat foods that you like and that satisfy your hunger. They may need to be somewhat different foods from what you're used to, but you can't change your diet without having a good repertoire of tasty and filling foods that fit that diet. If you try to do that, of course you won't stick to it.
Exercise, similar. You can only stick to it if you like it well enough and it fits your routines. If you try to make too drastic a change too fast, it's not sustainable.
Maybe the slow success tikana sees reflects your need to prepare a sustainable diet and exercise plan first.
