You can be very ambitious in your choice of how to lose weight fast. Some people aim to create a calorie deficit of 1,050 – 1,200 per day with an hour exercise, this can help them achieve a weight loss of about 3 -5 pounds in the first week.  However, this may be difficult to maintain. A feasible calorie deficit would be around 500 calories per day, in addition to exercise comprising of cardio and weight lifting.  Studies have shown that exercising in the early morning is the best time to achieve fat loss, whereas during the evening time will achieve a better muscle build –up.  Some people may choose to split their exercise session in to two times a day instead of one, being high intensity workouts. This could achieve faster results provided that you are controlling your calorie intake.  A healthy diet is important for weight loss, as the body’s fat burning process does not function well in cases of vitamin and minerals deficiency.  Achieving a healthy body requires a change in life style, not just a temporary diet.
