Absolutely.But you can't jus ttell people to eat less, it doesn't work. They have to know how to reduce their food so that they don't get hypoglycemic. If you have been eating way to much sugar and fat and then cut your intake way down and keep eating the same foods you will just set yourself up for failure. Eating less of the same food is not going to help. People are not over eating lean protiens, high fibre vegetables and omega 3 and 6's. You will still be deficient in these things and binge when your body tells your mind you are hungry.Does anyone even know what is in the food they eat. I.E: calories(lol) fat, sodium, carbohydrates, nitrates or protien. I could tell someone to up their protien to 200 grams a day and cut their carbs to 200, make sure they get 35 to fifty grams of fibre and increase their omega and unsaturated fats till i'm blue in the face. Whats it mean to a 250lb mother of two with a job and no time on her hands. You cna't tell them to do better because americans (and canadians) have been lied to and fooled for 30 years about health and nutrition by the food industry (don't take me there, it's too warped even for some of the most conspiracy minded people.)
