Actual adults have a "fat tooth" not a "sweet tooth" commonly found in children less than 12. Even though you can temporarly satisfy your craving with sugary items; the body is never satisfied therefore requests more. Its the fat content we crave. Why do you think so many people are addicted to fast food, and other food options they know are wrong and will kill them eventually, but eat it anyway? Its because they cannot overcome their fat tooth cravings.
I learned this from a health care conference for healthcare professionals such as myself.
If you try to eliminate the sugar your body will crave more fat, and or attain its sugar from fructose. Now, that becomes a problem if you have a fructose intolerance/sensitivity as I do. But you are choosing to eliminate that too...
Not saying this can't help but... its extreme and the odds are against you.
Let me give you an analogy so to speak.
One could assume that the reason patient X has Diabetes type I because he drinks a Coke a day since he was 5 years old.This assumption is wrong because Diabetes Type I is autoimmune disorder in which the body does not produce insulin (its congential-born with it). Eliminating sugar will do nothing for this patient- they will continue to have high blood sugar from lack of insulin. The same goes for Diabetes type II often mistakenly reffered to as "sugar diabetes". Elimminating sugar *might help* but will not resolve the problem. Diabetes type II is caused from the body's own tissues being resistant to its own insulin or from lack of insulin production. Education on nutrition is a must for both clients as the majority of blood sugar rise comes from carbs, not sugar, especially the empty simple carbohydrates. Eliminating these will help, but wont cure. Its chronic.
Now, your plan to me anyway sounds like my analogy. Sounds convincing, and good, but its not entirely correct. Elminating the junk will help, but all sugar is not practical; o healthy. Your body runs off it; it needs it.
It also still doesn't address the underlying problem. Which will be evident if you continue to break out.
Eat nutrient dense foods in moderation, skip the processed goods. Heck, white bread along has more sugar than a snickers candy bar. Choose wisely and eat smart.
So, just a for warning.
People get addicted to fast foods because of the salt and sugar content, not the fat.
When high amounts of sugar are consumed the brain releases a load of feel good checmicals. This is where the addiciton comes from.
