I don’t have any dietary restrictions, but about 10 years ago I recognized that I’d let myself become fat. As a tall guy (6’5") and someone who has been fairly fit most of my life, BMI calculators had never actually been something I was too concerned with. I had been 6’5" 225 for a long time, which according to a BMI calculator is barely into the “overweight” category. However muscle mass above average tends to throw off the calculator a bit.
So I’d never really concerned myself with my weight. However I had been in a minor injury that involved me stopping my normal workout regimen. Fast forward 1.5-2 years of eating junk food and not working out later and I was at 265 lbs and I looked and felt “obese” just like the BMI calculator said I was.
I’ve never been one for half measures. When I decided it was time to reverse that trend, I settled on an extremely strict regimen of planning out my meals so that I was hitting a specific number of calories consumed per day. I didn’t want to eat on the fly and count the calories later because I felt that lead to me making bad decisions during the day. A few days of going over my calorie intake limit and I was just inclined to forget the whole mess. Most other diet plans that didn’t involve calorie counting didn’t appeal to me because I felt like they were working on faulty premises. I can intellectually understand the law of thermodynamics. I understood everyone burned a different amount of calories per day, but as long as I ate the same amount each day and weighed myself every day, I could calculate an average weight loss/gain and thus I’d be able to (after a month or so) calculate exactly how much my body burned, on average, in a day. From there I could plan out exactly how much weight I would lose per week or month and plot out my entire weight loss.
This was a very involved process, it’s not fun or easy to plan a week’s worth of eating in advance. There is a lot of weighing things on highly sensitive food scales. A lot of what I ate were pre-packaged foods because the absolute calorie values on them made the whole process much easier.
Anyway, I never realized before then how social eating has become. Anytime I would turn down lunch or dinner invitations, people would act offended. At first I would just say “I’ve made other plans” and other noncommittal things. Eventually I just started flat out saying, “I’m on a weight loss diet, I don’t eat anything at restaurants because there’s no way for me to know how many calories are in the food there.” My thought was that when confronted with such an open statement, most people would lay off. That isn’t the case, people become obsessive when you won’t go out to a Mongolian buffet with them for lunch or won’t go out with a group of people for dinner. Even worse is drinking buddies who don’t understand why you can’t at least come down to the bar to “hang out” even if you aren’t drinking. (The answer is that it’s hard to hang out with a bunch of people who are drinking if you aren’t drinking, it makes you want to drink and relax. Once you’ve started to drink and relax it quickly becomes easy to drink a whole day’s worth of calories in a few hours on a Friday or Saturday night.)
Finally I had lost the weight, started exercising again, and I’ve never had that problem come up again. As part of my “life long” maintenance I weigh myself and chart it every day, if I ever see my average weight creeping up, I’ll usually just watch what I eat for a few weeks to fix things. I always remember that it took me about two years to get fat, and because of that it took me a long time to get rid of the fat, so as long as I never let myself even start to get fat again I’ll never be faced with a huge mountain of weight loss to climb.
My experience with what felt like constant pressure to eat (and often to eat unhealthy, high calorie foods) really made me sympathetic for the people that are significantly overweight and can’t lose weight. If you’re an alcoholic you can, with discipline, just get rid of all your friends that don’t respect your problem and insist that you drink with them. But when you’re fat, it’s very hard to do the same. People expect you to eat with them on occasion, people expect you to accept things like birthday cake at work or baked goods. No one really understands that no, it really isn’t okay for you to splurge today. For someone battling with their weight a single splurge can turn into a binge. Sometimes just by ignoring your diet for a day or two, you lose all that momentum and willpower that was keeping you going.
I almost think that if I were to do it again, I would just lie to my friends and tell them I’d developed some rare food allergies and could only eat very specific food and could no longer eat in restaurants. I don’t necessarily think that would stop the pushiness, but I think it would give me a better “response” and I wouldn’t have to explain in detail to people why I didn’t want to “cheat” for the day.
