There could be a couple of things going on here. It is normal for people to plateau for a short time after initially losing weight. What causes this is your body’s metabolism hasn’t caught up with your recent weight loss. Keep at what you are doing and you will start losing weight again in a few weeks.
The other problem may be in your hydration. If you are not getting enough water, it will effect weight loss. You need >64 ounces of calorie-free liquids (water, Crystal Lite, tea, etc.) per day. A good daily calorie intake for weight loss is between 800—1000 cal/day, depending upon your build and activity level. Exercise is very important: Calories in (eating) - calories burned (exercise) = effective weight loss!
In addition to the above, you should be getting 70—100 grams of protein per day, so you probably need a protein supplement inbetween meals (in order to get 90 grams of protein from beef, you would need to eat 10 oz a day…probably more than you’re able to get in). Adequate protein intake prevents “starvation mode” with the lower calorie intake that you have.
Good luck in your continuing journey!—Bruce Lovejoy, APRN
