I just bought a stockpile of tuna @ Costco. The cans I had before were 5 oz., 120 calories. The new ones are 7 oz, 150 calories. That's 30 extra calories a day. I like Chobani 100 calorie plain yogurt for breakfast. But sometimes, when the grocery store is out, I have to get one with fruit, for 140 calories. I was thinking of taking a multivitamin, and figure the gummies won't upset my stomach. They're 15 calories each, and I think you take 2. But 30 + 40 + 15 + 15 = 100 extra calories a day, or about a pound a month. That's exactly how I gained it all back last time. Wow!
