Following a strict diet, fasting, exercising etc you can expect to lose 1% body fat per week so at that rate you could lose 10% body fat in 10 weeks.
As you lose more body fat the progress will slow down so expect it to take up to 12 to 14 weeks to fully lose the 10% body fat.
I would recommend eating Papaya seeds as well everyday because Papaya seeds are very healthy for you and can help you lose weight even faster.
Papaya seeds can also help remove toxins from your body, promote healthy hearts and even ward off cancer so Papaya seeds are worth eating.
