Getting confused now...IF to lose fat.

Ok, I've been doing IF 16:8 for 6 weeks, and lost 6lb. My gym instructor advised to lose weight that I try an hour each day on treadmill in fat burn zone which I've also been doing for about 3 weeks. I didn't tell him I was doing IF and today he's told me ill lose the muscle mass I'm gaining in the 2 body pump classes I also do each week.
I've tried doing lots of different classes (6-7 per week) in the past and I don't lose the fat.
Im 5ft 2, 8st 2lb, approx 25% body fat and according to a calculator 39%LBM???
Can somebody give me some tips on losing the fat but not the muscle? Should I do the fat burning / weights session on a day with a calorie surplus and have a deficit on my rest days?
Finally I tend to workout at 6.30am and with the IF my first meal is 12am is this too long to go without food after excercise? Also my body pump sessions tend to be 9.30am or 10.30am. I have read loads on this subject but getting confused with it all. Thanks

    If you are trying to lose weight then you will inevitably lose fat AND muscle at the same time, its how the body works. You can't make your body only target fat. What you CAN do is preserve or maintain current muscle mass with strength training and getting more protein in your diet.

    Deficit for weight loss, surplus for weight gain, somewhere in between for maintenance. IF or exercise timing has nothing to do with it.

    5'2" and 8st 2lbs is a good weight for your height. So I don't understand why you think you are fat? If you diet at that weight you will start losing muscle strength and there is nothing you can do about it. (You don't have the fat to burn)
    I'd recommend a bit of exercise if you feel you need to tone - but don't cut calories. Concentrate on healthy balanced eating.

    If you want to gain muscle I would recommend a progressive overload program instead of body pump.

    25% body fat is a decent place to be for a woman. But you literally can't be at 25% BF and only 39% Lean Body Mass, because LBM is everything that's not fat. You might be 39% muscle. I'm not sure without looking it up, but that might be on the high side of normal range for women. I know the normal range for men is like 38% to 52% muscle vs total mass.

    Have a read through this thread about recomposition.

    http://community.myfitnesspal.com/en/discussion/10177803/recomposition-maintaining-weight-while-losing-fat/p1

    You probably would do better staying at 8st 2 and changing up your exercise to include some lifting. This will help resculpt your body.

    Here are some lifting programmes

    Thanks for your comments I'll defo look at the recomposition. I know I'm not fat and not worried about the scales but I do store fat around my middle, back and arms and have handfuls of the stuff on my tummy so have a permanent muffin top and my legs and bum are tiny.
    The 39% came from a calculator on legionathletics.com but strangely if I switch to lbs instead oh kgs it comes out at 84%??

    You’re overcomplicating it. A calorie deficit will help you lose weight (fat and muscle). It doesn’t matter how that deficit is created, intermittent fasting/iifym/flexible dieting/clean eating, etc. It’s the calorie deficit that is causing the weight loss not the eating style.

    Cardio (any cardio) will burn calories, adding to your daily calorie deficit. No need to be in the “fat burning zone”.

    Heavy lifting will help maintain muscle mass (which is a great idea). There’s: New Rules of Lifting for Women, Strong Lifts 5x5, and other programs. But the important thing is progressive overload (lifting heavier and heavier weights over time). Body pump classes probably won’t cut it.

    There’s no need to do a complex scheme. Keep it simple. Simple works.

    I'd fire your trainer because much of what they are telling you isn't accurate. There is no such thing as the "fat burning zone". This has been debunked for a very long time. Additionally, IF will not cause any more or less muscle loss than any other eating pattern. It's not how often you eat that determines muscle loss, it's the total caloric deficit you are in, the macronutrient composition of your diet (protein, carbs, fat,), and how you train. As pointed out above, you are unlikely to both gain muscle and lose fat efficiently. It is much easier to choose one goal and focus on it for a time then switch goals as appropriate.

    Classic example of a personal trainer bull *kitten* what they don't understand because they don't actually need any serious qualifications to get the title of personal trainer.

    Everyone's advice here is pretty on. However, I have a different opinion about wanting to lose at 25% BF. Just because other people might be happy to be that size, doesn't mean you should throw away your goal for theirs. You do have fat and room to lose if you want, but are perfectly healthy where you are now, and that's the difference.

    Thank you all so much that's definitely made me feel much clearer about what I'm doing. If I could ask something else, if I do weights one day and cardiovascular the next, does the cardio day count as a rest day if I'm not lifting weights? Also does it make much difference if I train in the morning and don't have food until around 12 noon? The IF suits me eating 12-8. Thank you.

    Alternating cardio and weights is fine. A lot of people do this.
    You may eventually have to choose a preference- don't worry about that for a while though.

    Exercising fasted is fine too. Just watch your energy and performance levels and adjust if needed.

    Cheers, h.

    I do IF and I'm toning up while losing weight. It works for me. I was stuck before I started eating this way and now have broken plateau and started losing again. I eat a small snack in the afternoon and a large dinner. For fitness I do Insanity 3-5 days a week and walk a minimum 8k steps a day. Your trainer would likely advise against a plan like mine but its working.

    And I do Insanity fasted without any issue.

    Nutrient timing is far less important than your total calorie and macronutrient consumption for the day. The fasted training is absolutely fine. Training early and not eating for several hours is not optimal. "Not optimal" does not mean it won't work, you shouldn't do it, it will ruin your workout, or it will ruin your results. It simply means not optimal. It's best to eat some protein and carbs within an hour or two of a weightlifting session. How much of a difference does it make? It's hard to quantify. Far less of a difference than meeting your goals for the day. If the fasting helps you adhere to your diet, then it's fine to wait to eat. I spent many years not eating directly after a workout or eating very little afterwards and met my goals just fine. I am better with dietary adherence these days and now eat a meal after training or within an hour or two and my results are anecdotally slightly better. Again, adherence trumps everything else so if waiting to eat helps you, do it! If you can manage to still hit your goals and have a meal after you train, all the better.

    That's great thanks for all the help. Going to find a lifting programme now and off I go.
