Rapid weight loss

At a point when i had got pretty squishy 3 weeks ago i started out prepping for a 2.5 week hike which i just completed. I'm a bit lazy about carrying and eating food so was probably averaging 1200-1400 kcal/day. Low, but not super low. Imagine my surprise when i stood on the scales 20lbs down from 3 weeks ago (my BMI was 24, its now 21). Jeans that i could only just squeeze into and would never wear out of the house are roomy! Anyways i'm super delighted at what i see on the scale but my energy is feeling low. How do i recoup without regain? Any advice/suggestions? In the long term i'd like to loose 10 more pounds but priority now is stability.

Losing 20 lbs in 3 weeks is really unhealthy. Hopefully a good chunk of that was water weight, but I would still be worried that you burned through some muscle mass as well. I would strongly recommend setting yourself for maintenance for a few weeks and make sure you are getting plenty of protein, fat, fluids, nutrition, and sleep to allow your body to destress and repair. You almost certainly will gain back some water weight, so don't be bothered by gaining a few lbs back.

Once your energy is back and you're reasonably sure no other consequences are sneaking up on you, set your goal to lose 0.5lbs per week.

In the future, it is really important to properly fuel and hydrate your activity. You can really hurt yourself if you don't. Please take care of yourself.

In 2011, I lost 16 lbs in a 12 days hike. I was 20 and was backpacking for 2 years and did some cost cutting by eating one meal a day that time. I lost a lot of hair and looked scrawny and sickly. Thankfully everything got back to normal once I came back and ate in smaller surplus and made sure I was taking in enough protein and fat for the following months.

You have lost lean muscle, and you need to get it back before you worry about losing any more weight. Muscle burns more calories, so losing it means you will not burn as much and will make it actually harder to lose now. Lots of protein, etc., as @kimny72 said. I hope you had a great time on that hike, and good luck getting back into a healthier state now that the endurance challenge is over.

You went on a 2.5 week hike and ate 1200-1400 calories per day? Honestly, I'm surprised you made it back alive. Two years ago, at about 200lbs, I went on a 4-day hike and averaged probably 2800 calories (I only logged once to conserve battery life, but all days were similar). I still lost 2lbs in those 4 days.

Next time, really plan your food beforehand and do the math to make sure you bring enough to fuel the hike.

Use MFP to help calculate your calories.

Enter your height, weight, and activity without any exercise. If you have less than 20 lbs to lose set your weight loss at .5 lbs a week. Log your food and any exercise separate and eat back those calories.
