When I was training for and running marathons not eating enough carbs made a very profound impact on my body's ability to keep moving.
It takes weeks to get adapted to burning fat and ketones and you must remain below a certain threshold of carbs for that to happen. Also, you must increase salt intake to avoid fatigue, dizziness and headaches, if any. There was a study on that, with Stephen Phinney as one of the authors. Called keto-adaptation. You didn't give it enough time, still consumed too many carbs, not enough fat OR salt. It is important go into this, very well informed or you won't succeed. Certain marathoners actually do better on low carb, break records.

QuoteCarbs don't make you get fat. Eating too much makes you get fat. If carbs alone made you fat I would have gained a lot of weight when I was eating over 400 grams a day. Instead I lost weight by keeping a negative energy balance. I was eating plenty of protein and fat then too, usually over 1000 cal worth.
Over time, too many carbs can make some people fat by rendering them insulin resistant due to chronic high insulin levels. This is well researched. Not everyone reacts the same but in many, it can make them fatter than they would be with less carbs. You may not be gaining weight for genetic reasons or other but excess carbs are harmful for other reasons, driving insulin too high constantly, increasing glucose load on the body. In the last century, we have upped the amount of carbs drastically compared to what we ate for most of humanity's existence. It is not surprising that diabetes has increased, perhaps cancer, heart disease. Read about it, Gary Taubes has provided many details about it in his book. It's been also shown in several studies so it's not just about being fat or slim but about
health.
QuoteIt's true that protein and fat, particularly fat, can provide most of your energy at low exertion levels, usually when your heart is beating less than around 70% max. At higher exertion levels the body requires glycogen which is produced from eating carbs. The reason is that fat requires oxygen to be converted to energy. At lower exertion levels there is plenty of oxygen available so mostly fat is used. At higher exertion levels where more energy is required there is not enough oxygen to convert enough fat to supply immediate energy requirements. So the body increasingly relies on glycogen that it can convert to energy without oxygen.
Again, not true. Check out Stephen Phinney, Jeff Volek and Peter Attia on endurance, exercising, marathoners, etc. You're about to learn surprising stuff.

On the issue of alcohol, it could interact with estrogen or other stuff taken orally so be cautious. It could increase dehydration and other side-effects seen with Spiro. I don't really enjoy it personally.
