I think this is really bad advice. How much you eat is incredibly important to whether you lose weight or not. You can gain weight while eating only healthy food. You can also lose weight on a pretty bad diet. Portion sizes are a very important part of the equation.

This strategy also eliminates all joy from eating will cause "rebound," equates to "dieting" that isn't sustainable

Here's some better advice when it comes to actually losing weight (again, the stated goal is to lose weight, not to radically improve the diet):

- Use an app like MyFitnessPal or LoseIt and log all your food, including condiments. Focus on putting in the correct portion/serving/size/weight. Don't start trying to make any change, just log what you eat for a week or so and see how many calories that is adding up to right now.

- Get a food scale to aid the above. It's very easy to eat larger portions and servings without realizing it. When you make food, prefer weight measurements over volume, and then the calorie counts will be accurate.

- By focusing on calorie intake reduction, you will naturally figure out which foods are more filling while keeping you in your calorie range.

- Eat 3 deliberate meals per day, do not snack mindlessly

- Indulge mindfully, with the right portion size. Again, I don't think it's necessary to remove all joy from food, because psychologically that's a recipe for failure. In my experience, that leads to hating the whole situation and giving up.
