Is 16lbs in 4 weeks too fast?

I started fasting 4 weeks ago where I only would eat one meal in the evening. Ive had the help of Adderall (prescribed) which has suppressed my appetite a lot. I started at 256lbs and am now at 240lbs. I haven’t really been exercising besides the activity I get at my job which is semi active where I’m at least walking all day.

Is this too fast? Want to make sure I’m doing this safely!

It depends. How much was your SW? When I first started, I lost weight at a pretty good clip but, over time, it’s evened out to where I’ve lost an average of about 8-9 lbs per month.

Edit: Sorry, just saw your SW. I don’t know. That seems like a lot of weight lost in 1 month. You must be in an extreme caloric deficit. Keep in mind that a lot of that early weight was probably water weight and your weight will fluctuate over time but as long as the overall trend is downward, you’re good.

Answer

It’s the Adderall doing that. You may not be exercising but your heart sure the hell thinks you are. Adderall rips your metabolism. Like your heart pretty much thinks you’re jogging around all day. So it’s not just the appetite suppressant but the added lift of the super fast metabolism.

Ps “safely”? Lol, then get off adderall. If you’re losing that much weight, that stuff is rocketing your blood pressure. Go ahead, buy a cuff and take your pressure about 3 times a day on it.

Answer

How much did you lose the first week? Typically, you’ll lose a ton a weight fast, as much as 5-15 lbs. This is mostly water weight. In a caloric deficit, body is burning the calories, and especially carbs that you eat instead of storing them, and then using your fat stores to make up the difference. Since there are no readily available carbs in your system, you retain a lot less water. Every 1g of carbohydrates holds 4g of water. So once you start eating more healthy and less, you drop water weight really quickly.

It’s also why after a big binge you can gain quite a bit of weight in a day. No, you didn’t gain 5 lbs from eating that large pizza, your body is just holding onto more water.
