Hi soooofat, it's godd that you have started a weight loss program, follow it close and you will see great results. Please take it one step at a time. Do not hurry to lose all the unwanted bodyfat in 2-3 months. You got to 284lbs in years, so you should not expect to lose all that weight in 2-3 months, consider at least 1 and 1/2 years,
To your Health,
