Question

Jackie is a healthy women.  She is 45 years old and 5'7" tall.  Jackie's current weight is 160 lbs.  She exercises 4-5 times per week but is struggling to meet her goal weight.  Jackie is seeking your clinical advice to lose 15 lbs in 3 months.  Her target weight goal is 145 lbs.​

Answer 1

Assuming her weight loss is going to happen through nutrition alone. This question can be answered if we make apparent a few points. One pound is equal to 3500kcals. Jackie needs to lose 15lbs in 3 months. Therefore, she really needs to lose 52,500kcals (15lbs x3500kcals). In 3 months this equates to a caloric deficit of approx 584kcals/day (52,500kcals divided by 90days). So in order to reach her target goals she’s needs to be in a caloric deficit of 584kcals a day for 3 months from her current caloric intake that permits the maintenance of her body weight.
