I have been IF'ing everyday (18 hours) for the past 4 months (couple of 40 hours thrown in) and have lost -2 lbs. Yep, have gained 2lbs but am losing BF still. Everyday I notice either a new vein showing some vascularity or more muscle definition. And, I can still bench 440lbs, so no strength loss.
People too weak to follow their own dreams will always try to discourage others.
