So for losing weight... If you are aiming to lose weight, one rule of thumb is to create a deficit equal to 20% of your TDEE (similarly, 20% surplus for gaining weight). So if your TDEE is 2000 calories, and you wanted to lose weight, you might consider a daily deficit of .2*2000 = 400 calories. This means you can either eat 400 fewer calories per day than you normally do, or exercise more such that you burn 400 extra calories per day. Most people do a combination of both. A pound of fat is 3500 calories. So this means if you hold a 500-calorie deficit for a week, you lose a pound of fat. One general rule that gets thrown around a lot is that you should try not to lose more than 2 pounds a week (1000-calorie deficit/day) unless you have a very high bodyfat percentage (30%+), because by that point you are likely to lose lean mass (i.e. muscle) in addition to fat, rather than just fat as desired. The more accurate way to gauge your caloric needs is through trial and error -- tracking your calories and weight and activity and seeing how your weight changes over time. From there you can either eat more/less or work out more as needed. Last edited by Reincarnate; 06-28-2014 at 12:03 PM..

Figuring out how much your body needs vs. how much you're eating vs. how much energy you're expending is a pretty basic concept.

It's nowhere near as vital as people make it out to be

This isn't a black and white issue. If you goals are athletic in nature obviously focusing on athletic goals should be your priority. If gaining or losing weight is your goal, diet is extremely important and one of the biggest and most common oversights of newbies to fitness. I see it so often it's painful. __________________

I have a physically demanding job but outside of it I don't work out except once or twice on the weekends when I play tennis. How'd I figure out the multiplier for that? __________________

It's basically doing the bare minimum to avoid being sedentary. "Moderate" might be something where you're not only on your feet a lot, but you're also doing a lot of moving (like a waiter, etc). If you've got a demanding job and you also do a little tennis, my guess would be "Moderate" and I'd start somewhere around there. But really, you can also count your calories for a while and see how your weight changes in turn, and get a better sense for what your real TDEE is.

Yes.

Think of it in terms of physics. You're creating new mass. Mass is energy. That energy has to come from somewhere. It comes from food. The excess energy from food after your other caloric needs are met is literally converted into muscle.

Someone astute might ask though, "Why can't fat energy be used to build muscle"? The answer to that is complicated, and generally can only happen when you're severely overweight, as the body has evolved to never want to do this (because it involves burning a fat surplus and the body would much rather store fat than burn it).

If anything it's easier, since they have less muscle, which means they will build muscle faster. 'hard gainers' are just people that don't eat enough food to bulk. They usually overestimate how much they eat because they often have small appetites. __________________

I've recently come to the realization that I'm not happy with my weight, and these guidelines are a great thing to follow. The result of the equation does seem high for me, unless I calculated wrong (converted: 83.9146 kg, 177.8 cm, and 22.83 for age because I'm about two months from my birthday at 0.4x DAE = 2579 cal). As far as the multiplier -- if I'm starting a routine on going to my apartment's fitness center in the mornings (mostly for cardio) every other day for a minimum of an hour, should I apply a multiplier of 0.4x or 0.5x for the DAE? I'm currently out of work, so I'm spending my time at home taking care of my two kids. I'm personally thinking 0.4x, just to be safe. Either way, I'm trying to hover around 1700-1800 calories when I go to the fitness centers in the morning, and 1500-1600 when I'm not. Is this realistic? I don't seem to be having too many issues keeping my calorie intake low. Last edited by TC_Halogen; 06-25-2014 at 11:57 AM..

Track your weight, but I don't think you will have any problems in the 1500-2000 range and you should get results relatively quickly. __________________

And I used this to determine my body fat percentage which also helped me find out my lbm: http://www.bmi-calculator.net/body-fat-calculator/ I always thought the amount of food I ate wasn't a big deal but after I started tracking my meals more regularly I noticed how much I was overeating all the time. But now I've gotten to the point where I eat just enough or sometimes not enough but I feel full for the day which is great. Drinking a lot of water throughout the day helps too. tldr tracking calories is important __________________ Twitter | Instagram | Snapchat: Nyokou Taeyeon - "STAY"
