Nature as "Hashem's Clothing"

From a Shiur by Rabbi Lieb Keleman on Relationships

Rabbi Keleman explains that it is important for us to view nature as an external part of Hashem, he used the expression, "Hashem's Clothing". Nature can change at any time at Hashem's will, it exists only by Hashem's will, but it is an expression of the external wishes of Hashem.

This Shabbos it occurred to me that while nature is "Hashem's Clothing" there is much that we can learn from observing nature. One of the things that we can learn is that when people are overweight they are not healthy. Since we know that Hashem wants us to guard our health, we can also know that Hashem does not want us to be overweight.
