I am with Kristine on this, but if you do want to give him some studies on exercise, and to help YOU understand how futile Exercise is for weight loss, here are a few short articles:
Diet is the key to good health, and without a foundation of Real Food, chronic cardio exercise does Not lead to weight loss. This was explained in a short British Medical Journal article “You Can’t Out Run a Bad Diet”
linked within this further informative article on energy balance. https://idmprogram.com/exercise-is-...gy-expenditure/
One author of the BMJ article is the famous South African marathoner and sports/exercise scientist, Dr. Tim Noakes, who has many talks and books about elite endurance athletes and low carb diets. Another author, the renown UK cardiologist Dr. Aseem Malhotra, wrote “Physical activity has a multitude of health benefits — it reduces the risk of heart disease, Type 2 diabetes, high blood pressure and possibly even cancer — but weight loss is not one of them.”
in his short Washington Post article, Take Off That Fitbit. https://www.washingtonpost.com/post...m=.5f853796175a
. Here it is in a nutshell:
Our waistlines aren’t expanding because people aren’t exercising intelligently or vigorously enough. You don’t need a new personal trainer, another Insanity workout video or a more aggressive CrossFit regimen.
What you need is the truth, and here it is:
Exercise — no matter how many gym memberships you buy or how often you wear your Fitbit — won’t make you lose weight.
When YOU are ready to lose weight, my suggestion would be to try a very LC/Keto/Atkins Induction/Westman plan (without reward meals, not CAD, since that hasn’t worked you) and when you want to exercise....add some gentle walking, or swimming, whatever you have available that does not strain your joints or punish you beyond your current fitness level.
But it can be done with no exercise...Dr Westman has a powerful video case study with a woman confined to a wheelchair, lost 50 pounds paralyzed from chest down. https://youtu.be/DR2c3yWnfLI
Wishing you all the best,
