Calories vs. Carbs

I'm really good about staying under my calorie count of 1200 and only eating back half of my exercise calories and weighing all food. But sometimes I go weeks without losing anything or maybe just half a pound. But this week I didn't eat carbs in the evening and I had a whoosh of several pound weight loss. I've always thought its calories that matter but there seems to be a difference who I eat fewer carbs. Is this something I should stick with or was it just a coincidence?

    Low carb diets can trigger quick weight-loss but nothing sustainable. Also note that right off the bat, it's probably just water.

    Let me get this straight though: You're eating 1200 calories as your base + 1/2 of your exercise calories? How much is that on average? 1200 seems really low...
    EDIT: How long have you been doing this? At 1200 calories your metabolism could have slowed down dramatically if it's been a while. Also note, .5lb loss per week is healthy. Anything more than 2lbs is probably too much to sustain and can be detrimental to your metabolism.

    Carbohydrates are stored as glycogen in the liver and muscles to be used as energy. With this glycogen is LOTS of water. Each gram of glycogen is bound to 3-4 grams of water. When you start eating a low carb diet, your body will go into your glycogen stores and use them up. Those water grams also leave with it. Hence, you have lost water weight.

    low carb for the purpose of losing weight is just one of many weighs to create a calorie deficit...low carb isn't magic..carbs in and of themselves do not cause weight gain nor do they hinder weight loss...carbs aren't the devil.

    you lose weight when you consume less energy (calories) than your body requires to maintain the status quo...there are numerous ways of going about reducing energy consumption...low carb would be one of those many. it's not magic or anything.

    if you low carb you will notice a more rapid rate of loss initially...these early losses are largely glycogen (essentially water)...when you low carb, you deplete glycogen. ultimately, it evens out and over the long haul, you don't lose any more overall weight with low carb than you do any other diet or plan.

    also, when you re-introduce carbs back into your diet, you will immediately gain some weight on the scale as your glycogen stores replenish.

    Oh, this also is partly to blame for the crazy amount of weight gain after a cheat meal. The stored carbohydrates bring with them lots of water, so even if the meal didn't put you 7000-10500 over your maintenance, you still gain 2-3 pounds due to all the stored water.

    Just to be clear, I've been at this for almost two months with about 15lbs to lose. I started at 165 pounds at 5 foot 10. I don't have a huge amount to lose and have lost just under 5 lbs so far. MFP a put me at 1200 calories so that's why im following it. Also, I could never cut out carbs completely. I'm just talking about not eating them
    With dinner like i usually do.

    How much approx ? 200g of glycogen depletion * 4 = a couple of pounds ?

    MFP put you at 1200 cals based on the information you entered when you created your profile including your height, current weight, goal weight, activity level, and desired rate of loss.

    With only 15 lbs to lose you should be set at 0.5lb/week, which is only a 250 cal deficit from your maintenance level, and you should be eating back at least half of your exercise calories (which you said you are).

    As others mentioned, if you saw a "whoosh" on the scale it may be related to less carbs, or other factors that impact water weight. If you like carbs, you can continue to eat them, if you are at a calorie deficit you will still lose. Or if you don't miss the carbs at dinner and find that to be a way to help you create the calorie deficit, then keep it up - but there isn't anything magical about cutting carbs out (or any other food group) at a specific time of day.

    High carb foods are usually very caloric, so cutting back on them is a good tool for keeping calories low. A large salad will have the same amount of calories as a serving of rice, with the salad being more filling. On a 1200 calorie diet, you must be VERY selective with your food and choose filling options.

    As a general rule - no. Carbs have 4 calories per gram. Fat has 9 calories per gram. High FAT foods are (by definition) the most caloric for a given weight. The "very caloric" high carb foods you're referring to either probably a) are also very high in fats or b) you're not comparing similar serving sizes.

    The dressing alone on a large salad would have more calories than a serving of rice.

    11 pounds to go - weight loss will be slow. Carbs have nothing to do with it.

    1200 before exercise is a default minimum. If you had picked a weekly goal of 1/2 pound a week (more appropriate) .....you would have gotten more than 1200 calories. Your choice.

    Fat loss is about calories. Weight includes more than fat. You can lose weight without losing any fat at all, and you can lose fat without losing any weight at all.

    Reducing carbs can cause water weight loss.

    The salad I eat almost daily has 300 calories, and it fills a very large bowl. It's about 4 cups of food. ti42doc058c7.png

    A cup of white rice has 200 calories. I can eat an entire meal for 100 calories more. The goal is to eat enough to satisfy you within your calorie limits.

    When I am picking side dishes for dinner (or any other meal really) I tend to avoid "carbs" like pasta and rice for no other reason other than I can get a greater volume of food for less calories by choosing other things. You can have 4 cups of Pictsweet green beans and still be eating less calories than that 1 cup of rice. This is true for many other low starch vegetables.

    I am eating a 1200 calorie diet as well, so I know it's challenges. Best wishes to the OP!

    As many people have point out, the difference in your weight could just be water fluctuations based on glycogen stores (why keto diets lose a lot of weight initially -- the whoosing of water out of the system). You're already at a pretty decent weight given your height, so it may be very difficult to lose much more weight anyway. You may be better served looking to just improve your body composition (i.e. increase muscle/decrease fat percentage).

    All that being said, it's also possible that you'd be better served with a different amount of carbs. Some lose more with more carbs, some more with less carbs.

    For example, there was a study done a couple years ago with obese women who were insulin resistant and those who were insulin sensitive. The insulin sensitive women lost nearly twice as much weight with more carbs. It was the exact opposite for the insulin resistant women. They lost nearly twice as much with less carbs. The protein and caloric deficits were the same across all groups -- so same amount of calories proportionally, but how they created their respective deficits yielded dramatically different results. If I could lose nearly twice as much weight by simply adjusting my carbs, I'd definitely want to know about that!

    http://onlinelibrary.wiley.com/doi/10.1038/oby.2005.79/full

    Almost half of the US adult population has insulin resistance (at prediabetic or diabetic levels) and the vast majority of them don't know it. That's why it can feel like a magic bullet or a small miracle for people who didn't realize they were insulin resistant and reduce carbs and see dramatically improved results.

    So you may want to look at your diet and see how much carbs you're eating. If you're eating something like 60% (like the insulin sensitive women), then you might want to consider dropping it down to something like 20-40%. If you're eating only 20-40% of carbs, then you might consider upping it to more to see if something shifts.

    But, as I said earlier, you're not in the obese category, so it may be simply a very slow process to lean out further -- which is typically what many see when they get to the weight/leanness you're describing. You may also see some benefit from a different way of eating such as an IF regime or a calorie cycle regime (or one that incorporates both). Folks that are already fairly lean often do one or the other (or both) to help with this when a deficit alone isn't getting done anymore.

    You are a volume eater......not everyone finds volume satiating.

    Green beans are a good example....4 cups of green beans are fat free & have fiber. This is way less satiating than rice is (to me). The salad example is different.....you have protein, fat AND fiber all in one meal, so of course that's going to be satiating.

    high fat foods often leave people feeling full for longer. That is one reason why many people favor low carb diets over low calorie diets

    I love me some fat. Fat is the thing I struggle to control most. But it's more about taste than satiety. Fiber and protein are what keep me full longer. Fiber is a carb I seek to eat more of rather than avoid.

    But that's not true at all. Carbs are no more caloric than protein (each at 4 calories per gram), and both are less caloric than fat.

    That's great, but anecdotal evidence does not prove an assertion. Also, your claim was that a serving of rice was equal calorically to a salad, which your own follow up disproves.

    Again, anecdotal. If you're limited to 1200 calories a day, yes, you often have to choose low calorie per volume foods. But that has nothing to do with carbs (for the record, the vast majority of the calories in those 4 cups of green beans are from ...gasp...carbs!)

    I understand exactly what your saying, I've reduced my carb intake just to see what my results would be and I lost a pound yesterday from today and I don't mind that it's water weight to start it's exciting to see the scale going down! I'm planning on continuing low carb and by that I mean reducing carbs not completely eliminating them, I might try the carb cycling as well to see if that will stimulate more weightloss and if I can go a day without the main culprit carbs I like ( baked potatoes, rice, bread, and pasta) but so far doing Great on that and am looking forward to continuing the process until all my weight is gone! Good luck with your journey and congrats!!

    Think long term. Calories in vs calories out. Whether it is debated or not, it works for many people, myself being one of them.

    Stay true to your macros and don't worry about day to day weight fluctuations. Weigh yourself every week at the same time (mornings before eating anything is usually the lightest). I see too many people going crazy over their weight between say tuesday morning and thursday midday after they have a big meal. It's not worth the stress. Bottom line: You will lose weight if you keep true to your diet.
