I have lost thirty pounds in a month by eliminating carbs and processed food. Also by intermittent fasting i.e. waiting 16 hours after last meal to eat again. I drink a glass of kefir or have a small bowl of Greek yogurt and fruit for breakfast, a tin of fish some kind of pickled veg and a piece of fruit for lunch and a reasonable sized dinner. No bread, no fried food, no refined sugar. And I try to get 10000 steps a day. It takes a bit of mental fortitude but once the crap is washed out of your system you will never crave junk again. Oh, and water. At least a gallon a day. The weight will fly off.
