Mary's Weight-Loss Tip

Don't deny yourself foods, just modify the foods you crave to fit a healthy lifestyle. Mary's family loves pizza night, so instead of excluding herself from delicious food and family bonding she adapted her pizza. She used Lavash Flatbread Pizza with reduced-fat shredded cheese, and lots of veggies for a low-calorie dinner alternative. 

How She Did It 

Mary knew she wanted to be there for her son and enjoy life with him and the rest of her family. Through much motivation she was able to find her inner fire to work hard and lose the weight without surgery. She held herself accountable and celebrated every pound she lost for increased motivation.

Jenny’s Weight-Loss Tip

Focus on portion control and eating high-fiber foods and foods rich in monounsaturated fatty acids, or MUFAs. You’ll eat less and lose weight but still be satisfied.

How She Did It

Jenny sought support through a structured diet plan. In the beginning, she discarded or donated any unhealthy foods in her house, labeled every food item in her pantry with a black marker, bought scales and measuring spoons, and started limiting the portion sizes of her meals. See her detailed weekly food journal for more inspiration.

Charmaine’s Weight-Loss Tip

Make small, realistic food swaps and build on your progress. Instead of eating greasy potato chips every day during lunch, make the switch to baked chips or slice vegetables. Stop reaching for the salt shaker and instead, go for herbs and spices like garlic, pepper, and onions that pack in flavor without the excess sodium.

How She Did It

Charmaine cut back on her meal portions and unhealthy carbohydrates like white bread and French fries in her diet, started taking probiotics to improve her gut health, and started cooking the healthy way, like poaching, instead of frying fish. She also made healthy food swaps like swapping ice cream for yogurt or switching to baked chips instead of fried chips.
