Get off your ass, plug in your iPod and MOVE. Walk. Get going. Do something.
Agreed, need to exercise. But disagree on priorities:
You are more what you eat than what you do to exercise.
When I refer to processed foods, I do so generally: Keep carbs down as much as possible... at least less than 100g, 50g is a good first target, IMHO. I’m now doing 20-30g. Increase fat, maintain protein.
Although, someone carb-limiting themselves is likely health-minded enough to not be sedentary.
