Same routine day after day :(

Your coworker clearly does not understand how weight loss happens.

It doesn't matter if you eat eggs for breakfast, a sandwich for lunch and a steak for dinner every single day. If you end with a calorie deficit, you will lose weight. It. The same goes for exercise. Your body doesn't get "used" to being at a deficit and then suddenly disregard the deficit. The weight loss may slow down as you get closer to your goal weight, but that's it.

I eat the same thing for breakfast and lunch pretty much every day, and I'm doing fine.

I've been doing this weightloss thing on my own since August. (By my own I mean without a coach/instructor/trainer/doctor/nutrionist/etc). I feel I have been pretty successful. Yesterday I just had a coworker that told me that you shouldn't do the same exercise 3 days in a row and you shouldn't eat the same meals more than 3 days in a row. I'm guilty of both. I like my breakfast. I like my lunch. I like my dinner. I change it up every now and again--but I like the same meals. I can understand her saying to change that up, but she said my body will get use to that food and my metabolism would slow down. Same with exercise. Is there any truth to any of this?

Your co-worker is a dingus and probably has no idea how weight loss works on a scientific level.

You should not heavily train the same muscles consecutively (there are exceptions to the rule). i.e. You should not deadlift heavy two days in a row, you need time for microtears in your muscles to repair.

Eat whatever you want as long as it is within your calorie limit. Your body doesn't think like "oh sh-t I'm getting 2 eggs & toast again, F**K YOU!!!". Your body thinks more along the lines of "hey thats some fat & protein, lets use this!". If you're a person of routine then more power to you. A lot of people say "switch it up" when you plateau or get bored of your current foods & exercise. If you're okay with what you're doing now and it's working for you then keep going.

Don't fix what isn't broken.

Hey Jaycie! I am not an expert on any of this stuff -- but I wanted to respond that I know an awful lot of older folks who are among the fittest and healthiest in their age group and they are ALL creatures of habit & routine. Like my dad (who is a healthy weight after years of obesity and managed to avoid 2 different surgeries through healthy eating and exercise)...he has the same breakfast every day and does the same 3 miles of mall walking M-F and sometimes on the weekend too. Or an elderly lady I know, she does her Aquacise (sp?) class 3 days a week and Tai Chi on the other days and eats DQ every Friday night. She looks like Helen Mirren, only Asian. She is over 70.

I know you're not old, but I just happened to use those people as examples ;-)

IMHO, people try to make this stuff a lot more complicated than it has to be.

I typically eat the same foods for lunch and dinner every day. I'm not bored of it. I do crave junky food sometimes (okay, a lot of the time) but I've worked hard to change my relationship with food. I'm eating my green beans and chicken because I want to nourish my body, not because it tastes good. Although hey, it does taste pretty good.

I don't have a problem with repetitive eating and I doubt that eating the same (healthy) foods or the same exercise is bad in any way.

I mean really.. think about it. Our ancestors would have eaten the same limited list of foods for months at a time during the off seasons. They would have done the same exercises each day. Walking, hunting, farming. I think people are quick to judge because they see you being successful at losing weight and they could be a bit jealous.
