Most individuals are able to achieve short-term weight loss. However, maintaining that weight loss is another story. So recent studies are showing our biological adaptations to the initial weight loss, which are limiting the weight loss and not promoting weight regain over time.
So skipping breakfast, or skipping breakfast and lunch and then having a dinner -- we see a couple of things with that phenomenon. First of all, when people skip meals, the meals that they tend to have tend to be much larger than meals that someone would have if they had the actual three meals a day. So it is possible that someone, in that one or two meals, could be getting all the calories that they needed, in addition to additional calories.
The other thing that happens in that phenomenon is they are missing out on opportunities to burn calories through eating. So there's something called the thermic effect of eating. So actually, eating is what burns about 10% of our calories in the day.
Some of the other things that can contribute to weight gain are endocrine disorders. So we often screen for those as well. Those can include thyroid disease, Cushing's, or polycystic ovarian syndrome. So we'll screen for those. And then we'll also look at some medications that you might be taking that contribute to weight gain. Some psychiatric conditions can contribute to weight gain or obesity. These include binge eating disorder or night eating. So we'll look into that as well.
There's been a variety of weight loss approaches studied that have been effective. So really, it boils down to finding something that we are going to reduce, to have a calorie deficit in some way, but also not restrict too much, especially different food groups. Many times there's a lot of restriction in ingredients or food groups, macronutrients. And they all are very important unless medically necessary to restrict something.
So at Chicago Weight, we really educate people on finding something that's sustainable and a sustainable approach that is really increasing the nutrient density of the food and decreasing those really energy-dense foods that are maybe laden with your solid fats, added sugars, sodium.
