Welcome Insekur
Good for you for recognizing a falt and trying to correct it. I agree with you, the Monday thing is just an excuse to pig out a few extra days. I think people originally had in mind, a new start, a new beginning should begin on the first / new day of the week. But you and I know thats not the case anymore lol.
Being healthy is the most important thing anyone can do for themselves, but even healthy and over weight will eventually catch up to you. The over weight part that is.
I think that slow changes in your habits are the best and longer lasting.
Good Luck with your new plan, what ever it is you choose and your right, this is an awesome place to get support, the people here are more than friends, they become family because they truly care.
Hugs !!!
