You're 27, and as such you can make some basic changes and see results without any changes except to diet and exercise. In 4-6 months you can reach your goal. No problem. (1-1/3 pounds to 2 pounds per week maximum.)
Calculate your TDEE(Real Quick)
10 x Body Weight in pounds, Female
11 x Body Weight in pounds, Male
Yours is about: 1477 calories per day TDEE just to maintain your weight
Drop that 200 calories per day for a week, then another 100 for another week, until you reach -500 calories daily less or get to about 1000 cal. daily.
Exercise
Either do HIIT (High Intensity Interval Training) if you are comfortable with that sort of routine, or LISS (Low Intensity Steady State)
You will drop body fat.
- Drink a lot of water throughout the day.
- BCAAs are a good idea
If you workout in the morning, maybe coffee, and or a pre-workout supplement.
As far as that product you mentioned is concerned. It's a singular waste of money and a scam.
