The book Fit for life, I tried it for awhile, deperate to be able to not feel hungry all the time like on other diets. What happened was I DID FEEL HUNGRY all the time. Just eating fruit in the morning did not give me any energy, I started to feel tired by lunch time. Then the choices you get to choose from, well it is hard to combine and really eat, especially when I also have to cut down on cholesterol and on a few meds. I just started to take the fruits and veggies, organic when possible, but have more regular meals and after a few days I feel better. Eating healthy, yes, stay away from processed foods. But food combining had me feeling lousy.
