I'm 7 pounds into the "Covid 15" despite daily exercise. I may give this a try and see if I see results

FWIW it will be easier to lower your caloric intake to align with the lower activity that is a result of lockdown lifestyle than it will be to boost activity to try to match pre-lockdown lifestyle. Weight control is practically entirely diet. Exercise achieves other health and lifestyle goals. Furthermore optimizing your diet during lockdown will pay dividends once you go back to a standard level of activity post-loc…

I know, everything you say is absolutely spot on :( it's just so much easier to motivate myself to workout than it is to diet. I was rowing (erging) twice a day burning an extra 500-1000 calories (pretty easy to do on a rower in about an hour of rowing per day).

Right before the pandemic, I entered a body composition challenge that just ended. I lost ten lbs of fat and gained one lb of muscle. Another guy lost 6 lbs of fat and gained 4 lbs of muscle. You can't trust your scale. Go by the scale in addition to how you look, how your clothes fit, and your body measurements. For better data, get a Dexa body scan.

There's only a handful of them[Dexa] in the USA, if I want to find something local (Kansas City) what should I be looking for?

The 4-s sprints employed an inertial load ergometer and were followed by 45-s of seated rest. So you would need to take a 5 x (4-s sprint + 45-s rest) = 245 seconds exercise break from work every hour and in…

Interestingly enough, a similar phenomenon does exist when using a compound called dinitrophenol. Naturally, like with every useful drug, it's been demonized and banned. What it basically does is make energy use inefficient, so a specific action (like clenching your fist) consumes more energy than normal.

Not all of those 2500 calories come from fat. Some will come from protein, carbs, and alcohol. Even if your body doesn't burn less of the others to compensate you would not get 1.43 times your normal calorie burn.

I'm from Utah, so I really have no clue, but a quick search revealed this: https://www.dexafit.com/locations/kansas/kansas-city

> I mean it is literally the holy grail of dieting. Slightly related but I have recently visited the US and I have been shocked how supercharged high sugar (ie addictive) high calorie foods are everywhere, like desserts above 1000kcal alone. It takes much more effort than in the other countries to manage caloric intake here, even eating random junk food where I live it’s hard to go above 3000 per day.

how so much more effort? unless you’re in the worst parts of town there are plenty of food choices. choose the good ones.

NICE, thanks, something I'll look into
