Yes Sir, this is what has worked for me in the past. Some call it the Adkins diet. Sugar, in any form, is bad for your body. Have to watch as many things have a ton of sugar naturally. Sadly, for me a t least, eating a low carb diet is damn near impossible. One of the problems with having multiple mental health issues is I seek "comfort" in food. Most of my comfort foods are either high in carbs and/or sugar.
But one has to be realistic. Eating 0 carbs is very difficult, just restrict them. Same for sugar.
Don't even know if he is still around, when I lived in AZ I used to listen to a radio show, think the guys name was Lance Dreher. His "diet" was very similar to the Adkins plan, protein and fats. (Bacon was actually pushed, just not the store bought brand if I remember right). I followed his plan, went from a portly 301 pounds to a lean and trim 190 pounds of muscle. Ran & lifted 6-7 days a week. Often would do both.
One thing, if you change the way you eat saying you changed your diet is setting yourself up for failure. A diet is short term...just saying....
Best of luck to you.....
