The good news is the first few pounds are the easiest to lose.
The bad news is that you will not see a meaningful difference in just a week, or even one month, not enough to be the only thing keeping you motivated, at least. Depending on what you are after, caloric weight-loss might not even be enough to reach a very specific look, though it will go a long way.
My advice to you: find a way to stay motivated that is not based on results. This needs to be a new mindset, a journey you are undergoing. You’ll need a sizable adjustment to your routine. Find a laborious project you are excited about to keep you off the couch and on your feet.
Most importantly, realize that weight loss is almost all about what you eat. It’s very hard to go on a caloric deficit just by exercising, because a) exercising will make you more hungry, b) will convert fat to muscle which is heavier (though leaner), and c) it’s a LOT more work and time. Instead, physical activity is more of a way of attaining a deficit without an extremely boring diet of lettuce and it also takes away opportunities to eat out of boredom.
You’ll feel more hungry than you are used to, especially in the first couple of weeks as your body learns a new metabolic normal. Drink lots of water to both stay hydrated, and to feel full.
A broken clock is right twice a day. Inventions are only good when they reliably work for all the intended solutions.
