The primary thing that carbs bring to the table are:
- Resistant Starch
- Phytonutrients (like those found in intact whole grains)
The drawback is that those carbohydrates which are higher in fructose can be more difficult for the body to effectively process.
The good thing about fats is that they can provide us with essential fats. Such as:
- The omega-3s, and
- The omega-6s
The drawbacks come from the other types of fats that we might also ingest. There are trans fats, which are harmful, and saturated fats, which are harmful in certain amounts (but harmless at smaller levels).
There are two types of ketones that I want to hone on in, which are:
- Endogenous ketones (those we make)
- Exogenous (those we can ingest)
When it comes to those that we can ingest, we can get those from purified ketones like gamma-hydroxybutyrate or some from medium-chain triglycerides.
The thing that I want you to know is that we can certainly consider ketones as a fuel. This means that if your body has more than it needs, you can still turn ketones into fat. If there is less fuel total than you need, ketones are unable to make it work differently in any way.
In order to really round out these types of fuels, I do need to mention alcohol. Alcohol is a compound that we can burn as fuel, but there is really no clear positive involved.
While there might have been some previous research about alcohol and cardiovascular health, these research studies are now in dispute.
In terms of negatives, alcohol has been linked to:
- Cancer risk
- Brain aging
- Liver disease
While it does act like a fuel, alcohol certainly works differently when compared to carbs, fats, and ketones. It really does not carry the same positives at all.
