Is sugar found in fruits- such as dates-bad for weight loss? How much should I have? (on a daily calorie diet of 1, 352) also dates have carbs! >_<

Is sugar found in fruits- such as dates-bad for weight loss? How much should I have? (on a daily calorie diet of 1, 352) also dates have carbs! >_<

YES, choose low glyc.: All sugars are carbs (though not all carbs are sugars). Minimizing sugar is crucial for weight loss. Some fruits have much more sugar than others. Glycemic index measures how much a food raises blood sugar. Dates actually raise blood sugar more than pure sugar! Low-glycemic fruits like berries, cherries ; apples can be eaten in moderation; avoid high-glycemic fruits.

Skin laxity?: Give yourself time! The skin might regain some tone over time. The pregnancy process causes a lot of stretch in the skin and separates the rectus muscles.
