People often like to compare IIFYM (which has been in use by body builders for, literally, decades) to other popular styles of eating and weight loss… (paleo, low-carb, etc.). What people don’t realize about IIFYM is that you can actually incorporate any and all of those eating styles into the IIFYM system. If paleo is your thing, keep doing it — but use IIFYM to help you get the most out of it! If low-carb is your thing, DO IT — but use IIFYM to help you optimize your nutrient ratios and lose weight faster!
The most common response I get, by far, is “I’m allergic to gluten/soy/dairy/nuts/etc, so I can’t do it”. Nothing could be further from the truth. With IIFYM you can literally eat anything. Take the foods you love, and the foods you can eat, and incorporate them into the program, and you WILL lose weight.
Remember, the core principle behind IIFYM is something you’re already familiar with — if you eat fewer calories than your body requires you’re going to lose weight. (Yeah, I’m sorry, it’s not magic). This is the same core principle incorporated in paleo, atkins, keto, etc. The only difference is that, in addition to counting your calories, you’re going to strictly control your ratios of carbs, fats, and proteins. (And, depending no your diet, you will adjust those ratios to match).
The point is that IIFYM isn’t a REPLACEMENT for other diets. It’s a way to eat whatever you eat more efficiently. You can eat paleo, and do IIFYM. You can eat gluten-free, and do IIFYM. You can eat low-carb, and do IIFYM. You can eat gluten-free and do IIFYM. You can even eat vegan and do IIFYM. You’ll find that by incorporating the IIFYM principles into your eating style, your body responds with efficiency, energy, and fat burning like you’ve never seen it before!
IIFYM is often referred to as “Flexible Dieting” because it’s just that — it’s extremely flexible. Body-builders love it because they can incorporate both weight-loss AND muscle building into an IIFYM program, just by adjusting their ratios and calories to match their needs. Vegetarians, vegans, and even non-gluten eaters love it because IIFYM gives them a simple way to ensure their body gets the nutrients it needs, despite cutting out large good groups.
I will be doing this for the rest of my life because it holds me accountable for what I eat, but it still allows me to occasionally work in the things that I love. I’ve enjoyed eating “at maintenance” (not trying to gain weight or lose weight) over the last week or so. And by incorporating the IIFYM principles, I’ve learned that my “real life eating” (e.g. not dieting) is going to be awesome. I can eat whatever I want. I just use IIFYM to keep my portions in check, and make sure I’m not overloading on fat, carbs, or protein (don’t wanna get fat!!)
It’s ridiculously simple, but the returns are pretty incredible.
