I have been on a strict fitness regime for the last 18 days. I have gone from 14st to 13st 5lbs due to "theromobol", "promax diet" and 2 protein filled meals a day as well as the odd peice of fruit here and there. my fitness regime includes 5 days in the gym (3 days on the weights and 2 days on the exercise bike (24mins, lv6, 10-11km)). Does anyone know whether the quick amount of weight loss is a temporary thing or is that my current weight. Many people have told me that its water loss or something, however i'm not too sure. I feel that i look slimmer and my muscles (arms, chest and shoulders have got more defined). Is the bike exercise regime that i am currently doing a good way to lose fat? And does anybody have any training tips that i could use, i would be very grateful for any help offered:\?
