You crushed your weight loss goal. Maybe it was 20 pounds, maybe it was 100. Maybe it was five. Good job. Regardless, that was the easy part — the real battle is just getting started.

“How do you lose weight?” is a great question, but the better question is “How do you stay lean for life?” Losing weight is a sprint (comparatively), but maintaining it? That’s a marathon. And most people tap out before mile three.

Think Christian Bale’s multiple transformations were extreme? They were. He’s literally been everything from an insomniac to literal Batman. Making such wild changes to your body can cause a lot of issues. Especially when done too quickly or too frequently. If naturally changing your weight too quickly can cause problems, what can a pharmaceutical do to you?

Ever notice how your abs can look shredded one day and like you swallowed a beach ball the next? Maybe not even days apart, but just hours? Perhaps even just after a meal? You’re not alone in this fight.

Think you need to sweat buckets to shed pounds? Think again. Your kitchen holds more weight-loss power than any treadmill on the planet.
