I've recently lost 45 lbs. I've done so on a vamped up version of the low carb diet. I do take breaks. Every two weeks I go off. It gives me something to look forward to, plus motivates me to keep going. I tell myself "2 more weeks, 2 more weeks". So yes, 45 lbs down from 267 to 222. The low carb diet is the ONLY diet I've been able to stick to my whole life! It does this amazing thing to your body called 'ketosis'. Look it up! No cravings, it really is amazing. I have a food obsession! But with this diet that is gone. I recommend any one who wants to lose quick weight to try it out. 45 lbs in 5 months, little work out, however I did pick up a cleaning job.
