Can someone please tell me the importance of carbs over fats? Why would a high carb high protein diet work for some people trying to lose weight?

Background info: I recently spoke with a personal trainer who suggested I consume 137:137:30g (protein carbs fat) at 1300 calories to lose weight (10 pounds) and gain moderate muscle.

I’ve been eating like this for nearly 2 weeks and I’ve gained weight in my face and arms. I also feel exhausted even after consuming healthy carbs.

    For one, your macro breakdown really isn't going to matter much for weight loss or weight management in general. To me, dietary fat seems low...carbs seem just fine and 137 grams of carbs is not a lot. Generally 130 grams or less is considered "low carb". Carbs are an exceptional energy source though and many people who train, especially endurance, eat higher carb diets. Protein is likely excessively high...but it's all the rage right now so trainers and everyone else under the sun is pumping protein, protein, protein, and more protein...don't get me wrong, it's very important...but you also reach the point of just making expensive glucose and piss.

    Most trainers are not remotely qualified to give nutritional advise and it is also illegal for them to do so in many states unless they are actually a registered dietician as well. A trainers specialty is exercise, not diet. Most trainers have little to no formal training or education on nutrition...they just spout off whatever the latest and greatest bro-science is out there.

    So if the macro breakdown doesn’t matter much, are you implying the issue is in activity or intensity?

    The trainer is a successful competitor in women’s natural body building and is also a nutrition specialist. We’re about the same height and she is absolutely shredded but I’m def not trying to get on her level right now.

    I’m also not as active as she is. For reference I’m 5’5” 122 lbs and have a really small frame. I have a desk job and do 30-45 mins weight training 4-5x week. I also take walks during breaks and will salsa dance and freestyle throughout the week for cardio.

    That would explain her macro preferences...those are very typical of a bodybuilder or bikini competitor or fitness model as they typically amp up the protein, do moderate carbs, and pretty low on dietary fat.

    If by "issue" you are talking about weight loss...that comes down to calories (energy). You can eat Twinkies all day (it has actually been done) and lose weight so long as your calories in are less than your total calories out (that's everything, not just exercise).

    If you've gained some weight in your face and arms, it could very possibly just be bloat (water) for a myriad of reasons. TOM, more salt than normal, higher carbs than normal, new training regimen, etc.

    That seems like a really low calorie goal to me, too: I'm 5'5", 125 pounds, age 65 . . . 1300 calories gross intake would be utterly punitive for me. I admit I'm a mysteriously good li'l ol' calorie burner, but even at 150+ pounds 1200+all exercise calories (so more like 1500-1600 gross intake) was way too low, felt OK at first but I hit a wall, got weak and fatigued, took multiple weeks to recover.

    I haven't had a problem at 100g protein, 50g fat as minimums (though it was a bit less than that while I was losing). I don't worry about carbs at all (experientially, I'm not very sensitive to carb level within the range I eat to balance calories - usually been 150g or so during loss, 200+ in maintenance). 100P-150C-50F would be 1450 calories.

    IMO, we don't need more than 1g protein per pound of lean body mass, though more isn't harmful.

    If your goal is muscle gain, Examine.com's research based calculator suggests 89 would be optimal as a minimum for you, but up to 133g could provide additional benefits, based on limited evidence, FWIW.

    I've done a couple bodybuilding preps and I never got below 0.3g fat per pound of bodyweight, and even at that level it was short-term.

    I'm a big fan of Renaissance Periodization and in their Minicut Manual (minicuts are no longer than 6 weeks) they have this to say (copied & pasted directly):

    To generate your deficit and make adjustments on a minicut, cut fats until you get to around 0.3g of fat per pound of bodyweight per day. Do not cut fats any lower than this, because you will need them for hormonal support and other basic functions.

    Macros only help people lose weight indirectly. If people eat a macro balance they find filling, they are more likely to comply with a calorie amount that creates a deficit.

    40% protein is one thing for women’s natural body building competitors but unnecessarily high for you.

    If you use the MFP method, you'd set yourself as sedentary and your weekly weight loss goal to a half pound per week, since you only want to lose 10 pounds.

    Since I don't know your age I used 30 years old. This gives you 1340 calories per day. (You'd get more if you are younger and less if older.) You would then log exercise on top of that, and eat those calories as well.

    Note: many consider the burns given by MFP to be inflated for them and only eat a percentage, such as 50%, back. Others, however, are able to lose weight while eating 100% of their exercise calories.

    I have to wonder of any of this is just your perception. When I started working out again and looking at myself in the mirror a lot I noticed things that were previously unremarkable.

    Also, I thought my biceps were getting bigger, but when I measured them I found they were actually getting smaller.

    Furthermore, I tend to bloat at certain times of the month. And if it's hot where you are, you could be retaining water from that as well.
