Not all advice is good advice, which is why it's important to also know what workout tips to ignore.
When it comes measuring your weight loss progress, don't solely rely on the fickle scale. Basing your definition of progress on slight fluctuations in numbers isn't necessarily accurate. Why? Your weight doesn't tell the whole story.
Changes in body composition—your fat to muscle ratio—aren't accounted for by the scale. You might weigh more, but you might have a lower body fat percentage and be sporting more muscle, and the scale won't reflect that. Other, more effective, ways to measure your progress include progress photos (which can better show how small, daily changes add up), tape measurements, testing the fit of old clothing and aiming to out-do your old gym PRs.
