What I'm saying is that if you eat below a certain threshold of
calories your
body will start retaining more of what you eat, thus the effects of a big meal will be more readily visible. This is why people who starve themselves and go on crash diets only get fatter in the long run, because they eventually relapse and binge eat and their
body absorbs more of it.
This is a good pinned thread to take a look at:

The Theory: Eat much less; weigh much less.
The Reality: Sure, if you subsist on 1,200
calories a day, you’ll take off weight, but it won’t be for long. Consider an analysis of 31 studies of long-term diets, where the diets averaged 1,200
calories a day. The report, published last April in American Psychologist, found that within four to five years, the majority of dieters in these studies regained the weight they had lost. “Psychologically, it’s difficult for people to adhere to strict diets over a long period because they feel deprived and hungry,” says Traci Mann, an associate professor of psychology at the University of Minnesota, in Minneapolis, and the lead author of the report. “Also, our bodies are brilliant at keeping us alive when we try to starve them.” Your
body becomes more efficient at using the
calories you consume, so you need fewer to survive. In addition, people who are put on a very-low-calorie
diet (800
calories a day) have an increased risk of developing gallstones and digestive issues.
The Best Advice: Don’t starve yourself. “If you want to lose weight and keep it off forever, you need a modest calorie restriction that you simply continue and never stop,” says nutritionist Christopher Gardner. But what’s the right number of
calories for you? Use this easy formula, a favorite of cardiologist Thomas Lee, editor in chief of the Harvard Heart Letter.
First find your activity level on the table below. Multiply your weight by the number indicated. (You may fall between two categories. If that’s the case, adjust the number by adding a point or so.) The result is the number of
calories you need to maintain your weight. Let’s say you weigh 135
pounds and do light exercise one to three days a week. Multiply 135 by 13.5 to get, approximately, 1,800
calories. If you want to drop some
pounds, try cutting out 250
calories a day, says Lee. In a year, if you make no other changes, you could be 26
pounds lighter. Exercise more and you could lose more, too.
