The Disease Reversal Diet is also the diet we are biologically adapted to. The logic for that is simple: the body is a self healing organism - when we eliminate toxic input, and get the correct amount of nutrition, not too much and not too little (which happens automatically on the disease reversal diet, we don't have to think about it, we simply eat as much as we want of the "correct" foods), the body begins immediately to "vector toward health on all fronts".
What that means is we immediately begin going toward our correct weight, and symptoms of physical (and even emotional) discomfort begin to lessen. Within a few weeks we begin to feel very noticeably better with increased energy and feelings of well being. Within a few months we are obviously undergoing a transformative process, noticeable to all around us, but especially to ourselves. We begin to feel amazing, typically for the first time in years. Within a few years we are quite literally a "new" person.
There are variations of this diet of course, the variations that meet our biological needs for fuel and nutrition more closely are also those that are more effective at disease reversal. This same diet reverses the variety of diseases that fall into the "post industrial disease" category, some more quickly and effectively, notably the vascular diseases (heart attack, stroke, and dementia), and type 2 diabetes.
Certain other diseases are also reversed, but a bit more gradually, depending on disease progression. Early cancers for example are reversible, especially those that are not yet symptomatic (those we are not yet aware of, as we know, cancers typically take a decade or more to become symptomatic). Our body intelligence, that complex of mechanisms that reverses diseases, does know however, and begins work on all pathological conditions once we eliminate toxic inputs. All pathological conditions, whether we are consciously aware of them or not, begin the process of reversal as soon as we begin using the diet we are biologically adapted to.
Other diseases reversed include the auto-immune conditions, and again, some more quickly depending on type and progression. In other words, all of the so-called metabolic syndrome conditions, or what some call the post-industrial diseases of dietary excess, can be reversed with the diet we are biologically adapted to.
There is very solid science on the phenomena of disease reversal through diet, an exponentially growing body of research, the earliest examples of which are now decades old.
Of course physical activity is an important component of any healthy lifestyle. The term we hear frequently is "diet and lifestyle", and it's true, we need more than nutrition, but nutrition is the key, and the most effective first step. The reason is simple: better nutrition increases energy and feelings of well being, and when we feel good and have energy we "feel" like moving. In fact it begins to come naturally, our bodies just "want to move" with increased energy.
Weight loss and moderate disease reversal can come with physical activity alone, but we know statistically very little of that is sustained. Other important factors for good health such as good sleep are also notably improved with the foods we are adapted to - these foods create much lower "load" on the body, consequently the body is more at ease, and rest and sleep come easier.
There are so many books to recommend. The first book I read that opened my eyes is "Prevent and Reverse Heart Disease" by Dr. Caldwell Esselstyn, formally a surgeon at the Cleveland Clinic. It's gets right to the point, an easy fast read. If you haven't read it yet, I recommend it very highly.

edit: A friend comments via email on this post, "and we eat TOO MUCH". My response:
The disease reversal diet has a technical name "ad libitum", which simply means eat until completely satisfied. Fiber is high, caloric density is low (compared to disease causing diets), and it is somewhere between difficult and impossible to go to any other weight than the correct BMI range while maintaining this diet. People on this diet for years become lean and stay lean, it's unavoidable. There is some variation of course within the healthy BMI range depending on other factors.
Here's a link to a study that examined the effect on common health markers in human subjects using an "ad libitum" disease reversal diet:
