Barring a medical condition, you WILL lose weight is you take in fewer calories than you expend.
Sites like MyFitnesPal (MFP), SparkPeople, LiveStrong, FatSecret, CalorieCount, and CalorieKing often crowd source their nutritional information from users without verifying their claims. There are many examples of entries under-reporting the actual calories and macros in a given product or item. This can result in you eating significantly more calories than you think are.
Alternatively, http://nutritiondata.self.com is not crowd sourced and can be trusted as a more reliable source of nutritional information of raw ingredients.
When eating out, try and find comparable commercial proxies for your dish. Corporate websites often post the nutrition data for their products. For example PF Chang’s, Pei Wei, or Panda Express can be used for Chinese food. Applebee’s, TGI Friday’s, or Chili’s can be used for American food. Subway, Quiznos, or Firehouse Subs can be used for Sandwiches.Share!
