7lb weight gain in a week.
Quality tissue of peace.
There is a science to this before you attempt to gain this kind of bulk you have to diet down to below 10 percent bodyfat, then after that you get off the keto carb up for one week, then keep increasing your calories every two weeks, eat a lot of fiber you should be shitting 3 times daily, your diet must be clean calories like yogurt, coconut oil,peanut butter etc, drink green tea, peppermint and chamomile tea to help with bloat and digestion, if you want to get big you cant just stuff yourself with food without knowing what you are doing.
