There is a thing called a Zollipop that is great for their teeth, doesn’t rot them out.
Zollipops The Clean Teeth Pops, Anti Cavity Lollipops, Delicious Assorted Flavors, Variety, 25 Count https://smile.amazon.com/dp/B00NUW6GHG/ref=cm_sw_r_cp_api_glt_fabc_DGGQFDK8CWPCR15KJWFA?_encoding=UTF8&psc=1
"Dessert should be once a week" never worked for me. I keep low carb, healthy sweets around for when I get a craving.
I eat Zollipops which are made with xylitol and erythritol, no sugar. Three of them to a 35 calorie serving.
I also make keto desserts to spread throughout the week. I just finished some tiramisu (almond flour ladyfingers, coconut milk whipped cream), and I have keto chocolate chip cookie dough in the fridge.
Weight loss is a lifestyle. Accept yourself and plan for your needs. Planned indulgence isn't a binge-- binges are uncontrolled.
They are a pretty tasty, teeth safe alternative to lollipops! My daughter also likes the Sparx candy http://smile.amazon.com/Xlear-Berry-Sparx-Candy-30gm/dp/B000P4JGBK/ref=sr_1_2_a_it?ie=UTF8&qid=1458194663&sr=8-2&keywords=sparx and I don't feel as badly about giving them to her. Just keep both candies away from pets as xylitol is potentially fatal to animals.
