I went from 250 to 190 on McDougalling - but to get the last few pounds off I did MWL.
When I went off back to regular McDougalling (but eating a lot of bread and occasional oily food and alcohol) - the weight crept back up to mid 190's
Going back on MWL this week - I dropped to 185 from 193 in three days.
Here's my mini-yoyo for the past year
My body is completely logical. If I go MWL I achieve a healthy weight. If I eat bread ad-libidum I go to just above normal into overweight BMI
