First of all, do not get overwhelmed and above all do not try to lose the weight you need in an unhealthy way. Remember that many miracle diets that promise you a lot of weight loss in a short time, generate harmful effects in your body, in addition to producing a rebound effect once completed. For example it is common in those cases to diet at this time of year and then recover all the lost weight and even increase it more during the August holidays. My intention is that you lose those kilos that you have left over in a healthy way.
With a healthy diet you can lose 0.5 to 1kg of weight per week. This means 2 to 4 kg per month. Therefore you have time to vacation to be able to make a balanced diet to lose weight and reach your goal without leaving your health along the way.
