Michelle Obama worked hard to create new USDA regulations on public school lunches.

Her efforts added limits on calories, sodium, fat and sugar for all food and drinks sold at schools across the country.

But in some schools, the new guidlines have added "mystery meats" and smaller portions, leading students to share photos on Twitter and sarcastically praise the First Lady using the hashtag #ThanksMichelleObama.

Some students just don't think they're getting enough food to make it through the day.
