My biggest obstacle to maintaining a healthy weight is a seemingly invisible “switch” that goes on and off in my brain. When it’s “on” I am in the zone and can avoid the most decadent temptations and will exercise faithfully. But, about a year to 15 months into my healthy lifestyle, the switch turns to “off” and I lose focus and revert to my bad habits of poor food choices (both in what I eat and how much I eat) and I become more sedentary. I am at that point now and I feel a slow panic building as the number on the scale inches upward. I know what I should do, but I am at a loss as to how to get my mojo back. Suggestions, anyone!?
