What you eat is very important.
Fat stores aren’t the first thing your body will turn to. After the carbs, your body will turn to breaking down muscle tissue which is not what you usually want.
Energy is the least of one's problem on a super restrictive diet like this one, but having the building blocks for muscles and cells and hormones is the literally vital.
There are trace amounts of fats and proteins in potatoes, not enough to sustain life long term. Enjoy having boundless energy, unable to build mass thus wasting and no libido whatsoever.
No libido? I'd like to see the source of that claim.
The western world has become "addicted" to protein and the claims on how much is necessary and recommended are extremely exaggerated.
If you are eating Yukon gold potatoes, and you ate 5 pounds of them, and according to my calculations you are looking at approximately 2100 kcal of which a little less than 1900 of those calories comes from carbohydrates.
We advise people not to go below 50 g of fat per day and according to the macros for Yukon Gold you wouldn’t even be getting a 10th of that amount.
Additionally, you’re only getting about 50 g of protein. We normally coach people to eat 1 g of protein per pound of lean muscle mass. So for 150 pound person that would be 150 g of protein per day or approximately 600 cal from protein.
"Lean muscle mass" excludes the fat on the body, right? A 150lb person should have less than 150lb of lean muscle mass.
USDA recommends 54g using their calculator. Don't forget the 38 grams of fiber! :)
All you need is an InBody machine. Many gyms and trainers have them.
Are you saying that views on carbs might change like it did for fat? Keto is pretty much the best supported thing we've got, plus diabetes being so prevalent, so the argument against carbs is pretty solid.
