ImageThe makers of TrimSpa recommend taking 2 tablets in the morning, 1 at lunch and 1 in the evening. Some people may require the maximum dosage of 6 tablets per day (the amount taken by Anna) based on their metabolism. The pills should be eaten with eight ounces of water for best results.

Along with the weight-loss supplement, a balanced diet comprised of healthy meals and snacks is recommended. Trimspa also suggests 30 minutes of exercise four times a week, integrating both cardio and strength training workouts.

Although bottles of Trimspa are flying off the shelves since the launch of the "Anna" advertising campaigns, there is nothing too crazy about this typical diet pill.

Side effects include insomnia, anxiety, heart palpitations, chromium toxicity, migraines and heightened blood sugar. A bottle of 90 pills will cost $34.95.
