I found the best & easiest diet for long term weight loss is the Low GI diet. Its not cutting out any meals & the whole family can do it, which makes life easier when ur making din dins. U dont lose weight super fast on it. Its more of a lifestyle change. I was on it for a while but got lazy & started cheating lol. If u just google Low GI diets heaps of stuff should come up.
Ive also tried the super soup diet. Its a great one for winter. Its good just to kick start ur weightloss. If u do it correctly u lose around 5-6kg in 7 days. Its only a 7 day diet tho. But if u go back to eating heaps of bad foods the weight comes straight back. And to be honest, as nice as that soup was, i never want to even smell it again!
I'm now on one of those 14 day detox diet things from the chemist. Not so much to lose weight, i just feel like i need to give my inside a bit of a makeover. Plus back on the Low GI diet. I dont really have that much weight to lose, i just wanna fit my old jeans again wahhhhh!!!
Anyway, i hope u find something that works for u. I know how hard it is to lose weight after having a child.
