How much is too much protein for a female losing weight ?

I’m on week 11 of a fitness plan with a trainer. I’m 46 years old. Good health except for IBS. I’ve lost some weight and inches and my arms are getting toned. I’m 5 ft 9’and I’ve lost 20 lbs and about 18 inches. I would like to tone up more and still lose about 10 more lbs. I dont even own a scale but my weight is probably around 168-170 right now
I went to the DR last week and had blood work for my annual women’s well check and my kidney GFR is a low 53. Down 6 pts from a year ago. I have no pain at all and I drink 75-100 oz of water most days.
I’m wondering if I’m eating too much protein. Between my eggs, tuna, a low carb low cal protein quest shake, fage yogurts, chicken breast, I’m eating anywhere from 100g-130g per day. I am keeping my fiber around 30g. Net carb between 25-40 most days.
Sugar is usually under 20g but today it was 23g.
Calories are not high enough I admit they are usually under 1000. I work out 1 hr a day 6 days a week doing some weights and cardio
My father is telling me my protein intake is way too high and probably causing my low GFR.
I am seeing a kidney Dr next week just as a precaution.

Some trainers overkill on the protein. I had a trainer who had me on 200+ protein at one point. Way more than necessary. My bloodwork, since I started all this bodybuilding stuff, always has me at having more urea in my kidneys than the recommended.
I have since read that most athletes have this slightly higher than recommended levels of Urea in their bloodowork too. So A little bit over OK - but way too much over - not OK.
I go for 2g protein per kilo bodyweight, or if on an aggressive cut, 2.2 Protein per kilo bodyweight. Not need for more than that. My Protein these days is like 140... nowhere near the above 200 that was being prescribed to me.
YOur body can't even with that much protein, so there is no point.
If you trainer is old school, chances are you are eating way more protein than necessary.
Good luck!

My trainer is a female, 30 and lean and muscular and in terrific shape. She wants me at even higher protein and more calories. I’m not comfortable with eating any more protein in fact with my kidney numbers I want to cut back on the protein a little to under 100g. I take no NSAID just some IBS meds Which shouldn’t affect kidneys. Blood pressure is great around 110/68 or lower. In fact my BP the morning of DR appt was 98/61 it was in the am and I was relaxed.
So I thinking I’m going to have to up my carbs and whole grains and slow down on protein while still maintaining low calories and healthy eating1 -
You’re eating less than a 1000 calories per day?? I can’t speak to the protein, but that calorie level is far too low to maintain good health.26
-
Protein is okay, calories are not. I would rather work on eating enough to avoid the hosts of problems undereating can cause before worrying about eating too much of a macro.15
-
Your protein intake seems fine, but your calorie intake is not. Not getting enough energy for your body can cause a host of issues, and I would not be surprised if that could be what's causing your issue.
I am curious how you are getting that much protein on so few calories. Are you eating nothing but protein shakes? I eat a pretty heavy protein diet, and mine is around 150 grams of protein for 2000± calories a day.
Focus on eating a more diverse selection of foods, including those that are calorie dense with healthy fats. 130 grams of protein is fine, but you are crowding out other macros that your body needs.14 -
agree with the above, i'm much more concerned about your total calories VS protein amount...1000 for even a sedentary person is too little much less with the work outs.4

Considering your stats, you should be losing @ 1 lb per week on average, you are losing more like 2. That means you should be eating 500 more cals per day. Eat more of anything honestly, but I'd guess you must be eating pretty low fat now, which isn't great either, so maybe focus on that.
If you are healthy, 100-130g of protein seems fine to me. But I'm no doctor and it might be a problem if you have an undiagnosed medical condition.
For a healthy person, there wouldn't be anything wrong with eating more protein than you are, as some people find protein filling, but there's no reason to force yourself to eat more if you don't want to either.
Please eat more food, and hopefully the doctor can give you some guidance and peace of mind.9 -
Fixing how much you eat should be your first priority.
Worth reading about protein and your kidneys....

I have been saving my quest chocolate protein shake as my snack before bed. It’s only 100 calls 22g if protein 0 net carb but some days I have it as part of my breakfast. My snacks are also high protein ( fage yogurt. Or an egg or can of tuna) So is my lunch ( grilled chicken and egg) baby spinach salad dinner is either chicken breast or turkey burger and veggies.
I’m going to limit my protein shake to 1 a day as my bedtime snack it does great for sugar craving
I’m going to cut down on protein a little. This morning I had plain oatmeal with some berries.1 -
You really should be eating more. Add some more carbs or fats. Anything.15

That's really worrying that despite so many people expressing concern at how little you are eating your takeaway from this thread is to reduce something and not increase anything else.16 -
I am going to be adding more carbs. I eat every couple hours1

i thought this was a great article and outlines recommendations: https://www.aworkoutroutine.com/how-much-protein/
the short version: "If you’re trying to lose fat, build muscle, maintain muscle or have any similar goal that would be helped by maximizing the benefits we covered earlier, then 0.8 – 1.3g of protein per pound of body weight is what I (and most others in this field) consider to be the ideal range for protein intake."1 -
Thank you for that article. I stil want to lose weight and i can’t help but wonder though if my high protein is having some effect on the GFR it can’t be such coincidence I dropped 6 pts in a year.
I’m going to see wha my kidney DR says but I’m going to try and limit myself to 90-100g of protein a day until I see him0 -
How are you getting 100-130 grams of protein on 1000 calories or less? You're only eating the aforementioned foods? How many calories is your trainer recommending?
I'm 135-140lbs and usually eat 130+ grams of protein daily (usually around 2000 calories). My bloodwork is always normal; so higher protein diet hasnot had immediate negative impact. However, you should consult your dr regarding your bloodwork.
You need to eat more; 1000 calories and any form of training is a recipe for burnout.6 -
Switch to plant-based proteins. It's MUCH easier on your kidneys. Animal protein is extremely acidic. Especially if you are eating 1000 calories of it and not much else. Get more healthy calories in.
Beans, lentils, beyond meat products, broccoli, greens, tofu, tempeh, hemp, plant protein powders, etc.
Check my diary for ideas!18 -

Protein at the levels you mentioned is typically fine, but if you do have some sort of kidney issue you might need to limit it. I'd talk to your doctor (I haven't had kidney issues, so don't really know what the GFR numbers you are mentioning mean).0 -

Wanting to lose more weight is fine but with only 10 pounds to lose do slow your rate of loss to a half pound per week.
When you plug that into https://www.myfitnesspal.com/account/change_goals_guided what do you get for daily calories (before exercise)?3 -
I am going to be adding more carbs. I eat every couple hours
How much fat and what quantity of fruits/veggies have you been getting daily, typically, alongside the protein, if you're eating that few calories?
When I was your current weight (a few inches shorter), 1000 calories would have been a debilitating level of undereating (even 1200 + exercise was too low, made me weak/fatigued). I don't know what the effect of muscle breakdown + undernutrition (fats, micros) + ultra-low calories (all of which you seem possibly to be risking) would be on kidneys/GFR, but I can't believe they have a positive impact on overall health risk.
I agree that consulting a specialist, as you plan to do, sounds like an excellent course of action, as does getting more carbs (plus fats, if you're under on those). If you're undereating veggies/fruit now, maybe eat such of those as don't trigger IBS symptoms, as a carb source? And IMO it would be a good plan to get fats in the 56-72g daily range at minimum, at your size.
Hope you get some (non-scary) answers from the specialist. Keep us posted, OK? Concerned! :flowerforyou:3 -
From what little I"ve read healthy kidneys are not adversely affected by high protein. HOWEVER kidney's already in decline can have problems with protein. Why are you having your kidney function checked and definately talk to your doctor.
a GFR of 53 would be stage 3 for CKD. This is not really a forum discussion anymore but a medical discussion to be had with a doctor.

With the 0.8-1.3g/lb LBM protein recommendation, can someone explain if this should be the same each day regardless of how much your total calories increases in a day as a result of exercise?
Eg say on a normal day of 1600 calories I aim for 100g protein, then the next day I burn 1000 extra exercise calories, do I still only need the 100g or should I be trying to keep the same % macro split as on the non-exercise days and thus eating quite a bit more protein?
Sorry to hijack your thread OP but it is sort of relevant and has been puzzling me lately.2 -
Oh and OP, please consider eating more fruit and vegetables for the micronutrients you need. A useful motto is ‘eat the rainbow’ so maybe add some berries/dates/figs/grapes to your yoghurt, veggies or a salad with your lunch and snack on some carrot & pepper sticks or throw an apple or banana into the mix.
The extra calories will help fuel your workouts and make you stronger/faster/improve endurance and your body will thank you for the variety & extra fiber too.4 -

Only the 100g, unless for some reason you like eating more protein when you have more calories, believe in extra protein after certain types of muscle-challenging workouts, or something like that. Staying with 100g is fine, but more is fine, too (within reason, of course). Percent splits are just an easy-to-calculate way to approximate sensible macro splits within a software environment like MFP's, and approximate is mostly close enough.
If you look at USDA/WHO information, they'll have some summary statements like "X grams for the average woman", but off in the details somewhere some information about grams per pound of bodyweight (they don't usually qualify it as healthy goal weight, but doing that makes sense to me around MFP where very often people are heavier than they want to be, and on reduced calories besides).
For example, I hit a minimum of 100g protein every day, but sometimes eat more (basically by cooincidence ). I target 50g minimum fats (this is the macro I'm most likely to undereat, personally, but am OK with close. I also aim for a bare minimum of 5 (80g) servings of veggies & fruit daily, and prefer 10+. After that, if there are calories left over, anything is fair game, including on days with lots of exercise where there are lots of extra calories. Maybe craft beer and pizza and gelato . . . !

Hi checking in. I went to see my friends new baby tonight and she’s a nurse. She noticed I’ve lost weight ( always nice) and she asked what I’ve been doing. I mentioned high protein and working out and I mentioned I was concerned with kidney function with my GFR being 53. I do not have all. My blood test results my DR said he mailed them Sonos I have to go pick them up but she said it’s most likely the high protein and my GFR should be at least 60. Eek. So I need to change up my eating and lower protein and eat more good carbs.
According to MFP weight loss calculator I should be eating 1200 calories, 150 carbs ( seems high). Under 40g of fat. I’m under all that today easily but my sugar is higher than usual because I had a banana for breakfast. Raspberries for part snack. Some strawberries for part of my lunch. I gave my sugar limit set at 20g but right now I’m at 40.
I’m going to eat less protein in morning, and eat more food carbs in am so I can keep my protein under 100g a day. More likely 90g. I’ll see what the kidney dr says Monday.0 -

Fat goal is, IMO, better understood as a minimum, not a maximum. The issue is that fat is high in calories (9 calories per gram of the macro itself, vs. 4 for either of carbs or protein, or 7 for alcohol). But extra fat within your calorie goal is fine.
There's also nothing wrong with 150g carbs. I eat 200g most days, in year 3 of maintenance, and wasn't far below that in the latter stages of weight loss. Inherent sugar (sugar nature put there, as in fruit and no-sugar-added dairy) is generally not a problem, according to maintstream health experts. The problem comes in with added sugar, which can drive nutrition out of one's diet (if one is sticking to a calorie goal) or drive calories to a surplus (if one is getting adequate nutrition elsewhere). That's because added sugar is somewhat calorie-dense, but nutrition-poor.
Fruit and dairy are nutrient dense, so the amount of sugar they contain is a non-issue, as long as you're getting enough fats and protein, not just fruit. (I understand that you're trying to reduce protein. I still think you should not over-react until you talk to a specialist, but eating a little less protein for now - like 90g - won't hurt you, as long as you don't try to completely eliminate it.)
BTW, 1200 calories isn't very many. MFP's calculator doesn't just "tell you things", it bases calculations on the weight loss rate you said you wanted to achieve (X pounds a week). 1200 can still be too few calories, if you asked for an weight loss rate that's too aggressive for your current size. Under-eating, something that it sounds like you have possibly been doing previously (at 1000 calories!). I'd suggest that you tell your kidney doctor honestly how many calories you've been eating, as that possibly could be relevant to diagnosis.
This is a good article about eating 1200 calories; I recommend you read and consider it:

No - at least 40g of fat. Fat is really important for a lot of physical processes, such as the absorption of various vitamins. If you get those good carbs as vegetables, consider frying some of them3 -
Update- kidney Dr is not concerned about anything. He is ordering more labs in 1 month. He said high protein diets trigger a false reading. He does want an ultrasound o them since a couple other numbers were off.
He said no red meat. No protein shakes ( damn). Everything else like eggs chicken turkey is fine.
What is a great healthy sweet treat? I like the weight watcher giant fudge bars.4 -

Well, that sounds like pretty good news!
And thanks for following up: I was hoping you'd get some reassurance. I hope the ultrasound similarly turns out to also be a non-event.
Enjoy your treat! :drinker:3
