There is a huge discussion going on in the blogosphere concerning what causes obesity which bubbled up at the Ancestral Health Symposium this month in Los Angeles. Gary Taubes has put forth the carbohydrate hypothesis (carbohydrates pumping up insulin), and Stephen Guyenet has put forth the food reward theory, and others say it is the Neolithic agents of disease –gluten, excessive fructose, and omega 6s as well as food reward. Lustig of youtube fame says that we are becoming leptin and insulin resistant due to excessive fructose. So if you are interested, it is good reading. However, I am only going to speak for me, an older woman who has lost 40+ lbs. and still has 10 lbs. to go that won’t budge. I have been losing and gaining all my life so I am sure I may have a messed up metabolism. There is probably some reason that I cannot lose weight at 1400 calories a day. I do practice 3 meals a day without snacks, seconds or sweets. But I cannot lose weight without watching my calorie and carbohydrate consumption. And I have always had trouble with S Days undoing all the good work of my N Days. Here is where I think the food reward hypothesis does have some validity.
We already know that processed foods and restaurant foods are chocked full of sugar and fat and salt combinations designed to get us to over eat. We are also now living at a time when foods of all types are abundant year round. We probably have the most variety of any diet since the beginning of mankind. We can go to local stores or walk into our own kitchens and food is readily available. It is obvious that our food environment is contributing to obesity because of all those darn high reward foods calling our name. But shouldn’t I have more control of the available food in my own home?
Here is a list of foods that I really have trouble limiting. Can we say FOOD REWARD?
Salty foods…nuts, chips, fries
Sweet foods…especially if combined with flour and fat…Brownies, pies, cookies
Breads, especially homemade and biscuits and cornbread
Coffee with cream leads to more coffee consumption than black
Creamy foods…butter in mashed potatoes, cheese, mayonnaise, creamy dressings, buttermilk
Fruits…ripe and juicy
Do I ever overeat vegetables without seasoning or butter? Do I overeat unseasoned lean meat? Unseasoned rice or potatoes? NO… NOT ENOUGH REWARD
I do not plan to put Guyenet’s plan into practice…i.e. eating foods separately, unseasoned, bland, etc. However, since food reward is an area where I do have troubles, I have to be very, very careful. I have learned that it is better for me to have some foods outside of the house on S Days, and there are some foods I just do not eat any more. Even on N Days I have to put some restrictions in place so that I don’t overeat.
How do you handle highly rewarding foods?
