Do not worry and do not get distracted/go off track! You have lost 22lbs in 5 weeks - that is amazing! If sticking strictly to the diet, the rule of thumb is 14lbs per month, so you're well in advance. Not unnaturally, your body needs some time to catch and up adjust.
If you haven't already been doing this - take your measurements: upper arm, bust, chest, waist, hips and thighs. You will be amazed at how many inches you lose AND you lose inches sometimes in weeks when you don't lose weight (or not much).
Keep going and drink plenty of fluids - you are doing great!!!
