Change your diet and start moving, heat up with rigorous physical activity.as mars you are stagnated and fixed, even your 5th is mars, fixed.the food you are eating l2 (jupiter also natural ruler of fat) is bad(in his fall) and makes your body bigger (exalts mars) and moon in Jupiter's domicile (you want to eat).In diets preferably we use a waning moon.Still if you want to reach your goal(lose five kilos) you can try, but it will be difficult, considering also that both sigs are weak as peregrine and cadent, with no power to act, although mars is more motivated due to mutual reception with mercury.
Good luck
