Across much of the world, movement restrictions are lifting, businesses are reopening, and gyms are coming back. While the next few weeks may paint a different picture, and cases are going up in many areas, many places now are seeing better overall trajectories. Deaths are down, which could be a lagging indicator and thus subject to a potential skyrocket. But for now, for better or worse, the gyms are opening.
Does that mean you should go?
Today we’re taking a peek under the hood and looking at some of the hormones involved in hunger and satiety, a.k.a. appetite hormones.
You might think of hunger as a gnawing feeling in your stomach and satiety as that feeling of fullness when you’ve eaten enough… or maybe too much. That’s how we experience the feelings we call hunger and satiety, true; but I’m talking today about the physiological drives to eat or stop eating that is driven by hormones.
Eating behavior is coordinated mostly in the brain by the hypothalamus, which acts as the control center for appetite. Hunger and satiety hormones deliver information from the body about how much energy you are taking in and whether you need more. The overarching goal here is energy homeostasis—balancing the energy coming in (via food) with the energy needed for the everyday functions of being alive.
When you have sufficient energy, your body is free to invest in growth, repair, and reproduction. Taking in more energy than you need can lead to excess fat storage and issues like hyperinsulinemia, insulin resistance, and metabolic syndrome. Energy deficits result in adaptations designed to conserve energy. In the long run, energy deficits might increase longevity, but they can also seriously undermine health and, for example, impair fertility.
Today I’m going to cover some of the key hormones that are involved in this delicate dance. This is by no means a complete list. Let me know in the comments if you have a burning desire to learn more about one of the hormones not covered here.
Avocados and avocado oil had a slow road to popularity, starting with a rebranding of sorts. There’s a bit of an internet debate around the origin of the word avocado. Some reports say that it came from the word ahuacatl, which is Aztec slang for testicle. As the fruit became more popular, that association wasn’t great for marketing, so farmers changed the name to “avocado” and even petitioned dictionary publishers to update the entry. Good move on their part, because “avocado toast” sounds much more appetizing than … the other thing.
Is Avocado Oil Good For You?
Back in the ‘80s when low-fat diets were lauded as the sure path to losing weight, people shunned avocados because of their fat content. About a decade and a half later when word got out that different fats do different things in the body, avocados were regarded as a welcome addition again because of their monounsaturated fat content. With the growth of the Primal and keto movements, people now embrace these fats, and avocados are regarded as a beneficial food that fits into a healthy lifestyle.

Who can help you reach your health goals every time? Nope, it’s not me. Although health coaches are a great resource for helping you set goals, overcome obstacles, and get out of your own well-intentioned way. For the record, that person is also not your spouse, your roommate, your friends, or your kids.
The one person who can make you reach all your health goals is YOU.
