Help! Macros/Calories/IIFYM

Have you used the online iifym calculator? It works out how many calories your body burns with your gender, weight, fat percentage etc (your tdee) From that you then need to have a calorie goal 3500kcal lower than that over a week (500 a day) to lose weight. I personally would find 25% carbs hard but if that's something you can stick to I've heard you are better off having a lower carb ratio when trying to lose fat. Depending on your goal weight you should be eating 1-2g of protein per lb of your goal weight so you maintain muscle mass so I've read on many forums. Hope this helps. Good luck

There are no ideal macros for fat loss. Beyond some basic guidelines it's just a matter of trying it and seeing if you are satisfied.

The TDEE-based approach often reduces calories by about 20% (from 2500 that would give you 2000) and that's about a 1/week (-500). With those numbers 1500 would be a goal of 2 lb/week. I think that's fine at your current stats (it's similar to what I did when I started -- I was 5'3, over 200), but you could lose on more if you wanted to try something more based on the calculators. I suspect that's the explanation for the different calorie numbers.

Good plan to best preserve lean mass when losing is to aim for around .8 g of protein per lb of goal weight (although more for satiety purposes is fine). Beyond that, don't cut too low on fat and experiment to see how you feel best. For many people just eating a generally healthful, filling, and satisfying diet is going to matter more than specific fat vs. carbs numbers, although some recommend .35-.4 g/lb for fat (forget if that's goal or current weight).
