Unfortunately, our health system is different from
that in Canada
and dieticians can be very expensive. It is always a good idea to talk to your doctor about a new diet, but if you stick with healthy foods, such as veggies, lean meats, low fat dairy, whole grains, fruit, nuts, seeds, beans, etc you will get the nutrients you need and if you watch portion sizes you won't get so many calories.
If you eat junk food - chips, candy, cookies, cakes, crackers, etc, stop.
