Fat Tuesday: Even if you eat a healthy diet, your genes can make you fat

Three sibling mice. The one on the left has a genetic defect that causes it to grow fat even though it was given the same diet.

Mice that have certain genetic defects can eat exactly the same healthy diet as their genetically normal siblings, yet still become obese.

Fat Tuesday: Hungry for love

AGRP neurons in the hypothalamus evoke eating by suppressing oxytocin neurons. Oxytocin is known as the “love hormone”, and so this brings a whole new meaning to the term “comfort food” since the new study result suggests that you can only feel truly touchy feely when your hunger is sated.

Researchers found that the molecular machine that produces a specific type of neuronal cellular membrane lipid, called glycosylceramide synthase, is critical for proper function of leptin receptors in arcuate nucleus neurons. The discovery opens a new potential therapeutic pathway to explore in the search for an obesity cure.
