Posted on Thu, 21 May 2015
Question: Hi Doctor, My daughter is 25years old, height 5'5" and weight 70kg. She want to reduce some weight but whenever she follows a diet plan prescribed by dietitian or doctor from second day onward she get loos emotions, nausea feeling because 1-2 days she take lots of roughage (watermelon, muskmelon, raw vegetables, papaya) but no chapati, oil, potato, banana. So i am worried that should she follow diet plan or just keep her regular walk on & eat home made food.

Brief Answer:
Moms always concerned about their daughters

Detailed Answer:
The calculations say your daughter should weigh 125 lbs, but I have always found that to be on the very thin level. What your daughter wants to reach for as far as goal weight is something realistic and achievable. Also, your daughter stopped eating the foods you mentioned because they are carbohydrates that tend to put weight on not take it off. Bananas, potato are starchy and she does not need them. Watermelon, papaya and muskmelon are fine. One thing that causes the nausea is going from a low fiber diet to a higher fiber diet without a gradual introduction of the fiber. You cant go from low fiber to high fiber overnight. Chapati, wheat, is fine, but portion control. She needs 5 starch servings,56 g protein (if vegetarian, 1/2 cup beans cooked so they arent gassey, 1 egg, 1 oz meat = 7 g, 1/4- 1/2 cup curd 2 milk servings (1 cup milk = about 8 g protein), 2 1/2 cup cooked vegies very soft, none raw at this point until she is used to fiber, 2 servings of fruit (1 small piece or 1/2 cup is serving) and 2 tsp of fat,( mostly virgin olive oil, 1/8 sl of avocodo) that equals about 1200 kcal. Also exercise routine, regular 30 minutes 5x per week or 150 minutes per week total every single week. Heart rate should be 70% or 220 - 25 =195 x .7= 137.5 or 140 beats per minute after warm up try to spend 20 continuous minutes at 140 heart beats per minute, then follow by a cool down and light stretch. As far as your wonderful home made meal, it depends on how the home meals are prepared ( preferably low fat, low calorie cookin), no seconds, learn correct portion sizes by measuring all foods until she can look at a serving and know how much she is eating. Did I address all of your concerns? I hope so.Please come back to see me if any clarifications are needed. Thank you for using HCM.

Thank you doctor. She lost 2kg in 2days by following this strict diet. Even she has added 1 chapati in lunch so that she don't feel hungry in office.
