There are three things about the furnace I know from following for her years and signing up to the free week trial she did back in 2019 -
1. It's not about food plans. She has said before that she doesn't like food planning...this might have been during her 'intuitive eating' phase. She only has sample US style plans as part of the program...
2. It's not about teaching people about the nutritional value of food . You don't learn about the nutritional information of different food groups and how to bulk out meals with low calorie nutrient rich foods. It's teaches you how to track your calories by logging stuff in MyFitnessPlan and then typing that figure back into a €79 excel sheet. It does a really clever thing where it divides by 7 to give you the daily average.....
3. I can't imagine the exercises that are in the plan burn more than 200 calories a day. The majority are body weight and hand weight exercises. (For comparison a woman will burn about 200-300 calories on a 5km run. A 5km run is tough!)
Ok, so you don't learn how to overhaul your diet, cook nutrient dense low calorie meals or do intense exercise sessions while on the plan. With that in mind someone may need to explain calorie deficit to me one more time because I am massively confused.....
Let's take Kathleen* as an example.
Kathleen wants to sign up to an online weight loss/fitness coach as she's put on a bit of weight recently. She's in a witness protection scheme so needs to find a program that will hide her identify from the people she's hiding from. She finds the OH Oven instagram and can't believe her luck that there is an online coach who protects the identify of their clients at all costs! Amazing!
She signs up to the OH Oven and is surprised by how much more food she can eat while on the Oh Oven plan. (She can now eat all these magical 400 calorie beef cheese burgers that she sees Siobh herself eating....she might even have two!)
She wasn't able to lose weight before joining the OH Oven so that mean's that Kathleen must not have been in a calorie deficit before joining the OH Oven. And if she's eating more now then she must be consuming more calories....so how is she in a deficit now?
Kathleen must have been eating Kälteen Bars (Mean Girls reference) thinking they were rice cakes.
Losing weight is hard, if it was easy we would all be at our ideal weight. Nobody want's to eat less to lose weight. So if you hear someone continuously say 'You can eat more and still lose weight' it might hook you in. But it's a scam and doesn't make sense unless you are training at athlete levels to create a calorie deficit of 400-500 calories a day (not My Protein 'athlete' level...actual athlete level like Serena Williams...)
*Kathleen is not her real name. Her name has been changed to protect her identity.
