Can I go on Tony Ferguson while breastfeeding?

[avanliamsmum]

I'm getting desperate to lose the baby weight (and some) I gained during my pregnancy but I'm still breastfeeding my almost 7mth old son. He's not taking solids at all at the moment, no matter how much I try. Should I wait until he starts eating solids to start the Tony Ferguson diet or should I wait until I have finished breastfeeding full stop? I don't want my milk supply to diminish, thats why I'm asking, as I heard going on a drastic diet can lose some of it.
