Also, the suggestion cutting out snacking is a good one. Three meals a day is more than enough for a healthy person to live on. I myself am currently living on only two meals a day, no snacks. I have had no issues with health, focus, or staying awake.
Everyone is different.
I am doing really well with 3 meals a day–two light meals (e.g., boiled egg, apple, a few crackers), and one “heavier” meal (e…g, meat loaf, mashed taters, green beans). No snacks other than Diet Coke. I will often have a piece of cake or a brownie with my “heavy” meal.
I’ve been doing this for almost a year now, and I’ve lost 33 pounds. The rate of weight loss is about 3 pounds a month–very VERY slow, not even a pound a week, but it’s so much better than anything I’ve ever done to lose weight! I am eating normal foods, not stuff I have to buy at a health food store! I am eating fruit—apples, oranges, raspberries, things I have eaten since childhood. I am wearing clothing that I haven’t worn in a decades (so retro!) and even that is baggy on me. And it’s simple–3 meals a day. Regular meals.
But for my older daughter, who is 36 (almost 37), this would never work. She eats every few hours, and carries snacks with her (Kind bars, nuts, etc.) because if she doesn’t eat every few hours, she gets so weak and sick that she faints. When she’s home, she’s constantly asking when we’re going to eat.
She eats very healthy foods, and doesn’t drink soda at all, and has cut alcohol to a glass or two of wine a week (small glass). She’s thin–she actually weighs less than when she was a teenager. (I believe she wears a size 4.) She’s strong and athletic–figure skates and speed skates. She walks everywhere in the Big City, and lives in a 4th floor apartment (no elevator!).
She’s just different than me–she has to eat!
So I think that everyone has to find their own way when it comes to food. All bodies are different.
