Biggest Loser Trainer Tries Keto for 17 Days, Here’s Her Verdict on It

A friend of Jen Widerstrom asked the fitness expert to try the ketogenic diet for a day, and she agreed, treating the whole idea as a joke.  The Biggest Loser trainer had never been a fan of the keto diet, because she believed that like its other diet predecessors, it was just a diet fad that will disappear and be forgotten.  A day after the diet, Widerstrom documented the result with a photo, and decided she wanted to try the diet for several days more. So she announced through an Instagram post on January 18 that she will give the diet a chance and see what will happen.

Widerstrom said that her decision to try the diet for 17 days was made because she felt really out of shape.  She took to Instagram to prove how out of shape she was, and the photo clearly showed she was bloated.

The fitness trainer said the past six months before she started the diet was a difficult period for her.  She did not specify what problems she went through, but mentioned that she went through a lot of stress that resulted in her binging on alcohol and chowing down fast food.  She drifted away from her healthy lifestyle, and would not have stopped until she saw the negative effects her actions had on her body.  Widerstrom said the most affected part of her body was her stomach.

Seventeen days after she started the ketogenic diet, Widerstrom showed how effective the diet was in bringing her tummy back to its original flat size.  You may wonder what is in the ketogenic diet that helped Widerstrom get back into shape; here are some details that may help you.


The concept of the ketogenic is quite simple; it is a diet that is high in fat and low in carbohydrates.  The diet significantly reduces the carb intake of an individual while increasing fat intake, protein is also part of the diet.  Basically it is a diet high in natural fats mixed with some protein-rich foods.  Because the keto diet is low in carbs, and individual on this diet gets fuel from the foods high in fat.  Once the process of continually relying on fats for fuel becomes stable, the body enters a state of “ketosis”, which is a metabolic state where the body loses weight.  It is vital for a person on the keto diet to not divert by consuming carb-rich foods, because this action will kick him or her out of ketosis.


With the ketogenic diet, the macronutrient is as follows, 75% of the person’s calorie intake should be from fat, 20% from protein, and 5% from carbohydrates.  Foods allowed are saturated fats such as coconut oil and ghee; polyunsaturated Omega-3 fats that can be found in salmon, tuna, and other seafood; and monounsaturated fat that is also rich in Vitamin E that you can get from olives, almonds, macadamia nuts, and avocados.  The diet is allowed some protein, too, which can come from animal meat, seafood, and eggs.  The best kinds of vegetables for the keto diet are dark and leafy one such as kale and spinach, cruciferous vegetables like cauliflower and broccoli, nightshades such as tomato and eggplant, and root Vegetables like garlic and onion.  As for fruits, only citrus fruits are allowed in the diet, since some fruits are packed with sugar (banana is a no no). You know what is great about the keto diet?  Cheese and bacon are not forbidden!

As Widerstrom posted her before and after photo on Instagram once her 17-keto diet ended, she wrote a message to her followers saying that she discovered she had the power to let stress takeover her life or fight back and try to cope with it.  And as for the keto diet she tried, the fitness trainer said she is now a believer and was impressed by how fast she saw the result of the diet.  However, she has no plans of sticking with the diet, as starch is an important part of diet for someone who does strength training and heavy lifting like her, and starch is one of the banned foods in the keto diet.
