Jim Katsoulis explains a common weight-loss mistake: people over-correct by drastically cutting calories, which is unsustainable. He recommends a more sustainable approach: calculate the percent of body weight you want to lose (example: 200 → 160 lb = 20%) and reduce daily calories by that same percentage (apply ~20% to a 2600-calorie baseline) instead of making an extreme cut.

Questions this video answers

Starting weight 200 pounds; goal weight 160 pounds.

20% of body weight.

The number one weight loss strategy mistake that I see people making over and over again is that once they get motivated to lose weight, they way over correct. So, for example, let's say an Average person's consuming 2600 calories a day, and all of a sudden they say, that's it, I got to lose weight. So it's very common for a person to say, I'm going to cut out 50%, 60% of the calories so I can start losing weight quick. And it's such an extreme drop that they can't sustain it, they can't keep it up. And then they just go back to what they were eating originally. So nothing ever changed. So an alternative to this is to figure out what percentage of your body weight you want to lose. So, so let's just say you're 200 pounds and you want to be 160 pounds. So that would be a 40 pound weight loss, which would be 20% of your weight. So what you can do is you can apply that 20% to the 2600 calories and cut down 20% of the calories, and that's going to get you a lot closer to your goal weight. Now, again, this math isn't exact, but it's a much better way to conceptualize in your mind so that you approach weight loss in a much more comfortable and sustainable way. So you're cutting 5, 600 calories instead of 12, 1300 calories.
