I finally decided to make a significant change last year. It started with me doing meal prep for my lunches. Previously I would eat out for lunch every day, and I would never make good choices. I was able to lose about 35lbs by just doing that and making no other changes in my life.
In August, I decided to start the keto diet. I started not for the weight loss reasons, but for the lifting of the "brain fog". I didn't realize how much carbs controlled my life until then. Eating keto 100% changed my life for the better:
* My relationship with food has completely changed. I am now concerned about what I'm eating, nutritionally speaking, instead of just quantity and taste. I am eating a lot more whole foods.
* My overall pain level has gone down significantly (I have back problems).
* I literally crave vegetables. My first couple of weeks I ate nothing but bacon and other unhealthy meats. After a while, all I wanted was a big plate of broccoli!
* I have much more energy and mental clarity. I also noticed my recovery time from working out is lessened.
As of this morning, I weigh 196lbs. I don't know how long keto is sustainable for, but I plan on sticking to this for the long term. If I do stop, I will definitely apply the lessons I've learned from going keto: mostly eat whole foods and carbohydrates that have nutritional value.
