re: diet
i've gone kind of the body builder route of trying to make high volume/low calorie/high protein foods, that taste pretty good. further down the scale is a general carb reduction if i can. eg. my (protein) pancakes use spelt flour vs. white flour. it is lower on the glycemic index and has less carbs; it is certainly not something a keto person could use though. note that volume might make you feel fuller, but things like fat or certain other carby foods (taters) make you feel more
satiated.
dunno your make vs. buy but kind of enjoy the ritual of making some things now, particularly baking. maybe because it's a bit of an art/science and fun to try substitutions. i'll do my pancakes and/or brownie and/or cinnamon thing at least once a day. why high in protein?
- protein has a high thermic effect - it takes more energy to break it down than fat or carbs. so you'll burn some of your intake here.
- if you're lifting (you should be lifting) you need sufficient protein for creating new muscle tissue. the broscience body weight in lbs as daily grams target of protein seems a good target.
- if you're in a calorie deficit, your body will not burn fat. it will burn fat and muscle. you can help stem the cannibalization of your muscle by eating more protein. but you should also lift to say "i need this, don't take it from here"
buy a food scale down to 0.1 grams and measure your stuff. at least have a clue about serving sizes and what you eat to start. i would write things down (if you truly get tired of tracking this anally, you don't need to do it, but i would advise it to start just so you have a clue about your intake and what x amount of calories looks like in food y)
as far as buying stuff, protein bar is great in the city (buffalo chicken) and chipotle is great everywhere. going veg heavy and leaning towards spicy foods in general you can have tasty volume.
if you get anal about your tracking, you can basically eat anything and lose weight, just incorporating it into your diet. i had triple cheeseburgers and brownies
constantly in thailand. this was in part because i tossed my bottom bun away and ate the burger with a knife and fork, paired it with a cup of corn from 7-11 (usually), my brownies were my creations, and my overall calorie burn was high. you can eat whatever your favorite foods are if you leave room to accommodate them. note: eating an entire purchased pizza however will make this a bit of a challenge, that one is actually tough
there seem to be some longevity or growth hormone benefits from IF; not sure i'd be down for that as a long term lifestyle change. as far as weight loss, all i think you're primarily doing is forcing yourself to stick to eating less meals though. eg. the night or work or whatever snack you avoid if you stick to a large IF window religiously. now that my work/life timezone is the same, i might try some kind of non-eating window vs. eating all the fucking time, meh we'll see. my own routine won't stabilize for another week once i move into a semi-permanent living situation.
re: supplements
you don't want to be too restrictive on foods as you can end up with deficiencies if you only focus on macros. eg. if i only ate all my protein concoctions i'd be fucked on various vitamins and micronutrients for sure. so try and get in a variety of veggies. i take a daily multi-vitamin and pee most of it surely, seems a decent thing to still get something out of.
i take a fish oil tablet too. really the big thing that i think matters though is 5g of creatine spread across 2 meals daily. i also use lots of protein powder. casein, whey, used to have some unflavored but vanilla you can kind of put in anything and can adjust to chocolate with cocoa powder. so i recommend a good tasting vanilla. IMHO hard to hit a protein goal of body weight efficiently (with less fat/carb calories) w/o protein powder.
re: activity
110% you should be lifting. this does not actually burn all that many calories. but it does tell your body to keep muscle. it will help you recomp your body as well. i don't do any real cardio (don't enjoy it) but if you do, probably want to stagger completely (like lift in morning, cardio evening) or stagger days. my muay thai in a way probably counts a little as that (and does burn a ton of calories) but IMHO i would not advise you to go run a 5k every day. however i would advise you to walk 10k fitbit steps every day. park far from jewel when you go grocer shopping. go find your breakfast spot with a compatible macro meal and walk to there every day or something. i could walk every day to get a shakshuka in thailand, with no bread or keto bread that was like the best meal/activity ever.
rather than cut calories, if you want to eat nummy things, just add steps and fit the food into your calories burned/consumed equation. you could add straight cardio but i think it is kind of the enemy of gainz in the gym. and that new muscle you add will help eat your calories so you want to maximize those. also get 8 hours of sleep for muscle building/fat burning/mental health/etc - although i literally never do. there are calorie consumption calculators you can use online, although i posted in the workout thread that i got a dexa scan upon returning from thailand and did a resting metabolic rate test as well - i came in reasonably under what common online calculators said i would burn in a day just doing nothing. so keep in mind those can be off, and if you're on a fine line, you could think you're in a deficit based on some online calculator and even religiously tracking your food intake - but the reality is your own body might be at maintenance at that point instead.
