Analyze why Claire has gained weight in the following scenario.
Claire has swapped her breakfast of an egg and muffin sandwich every morning for a single blueberry muffin in order to make healthier decisions and ultimately to lose weight. After three weeks of doing this, she actually gained weight.
Blueberry Muffins are high in sugars and carbohydrates. The bread contained in the muffin will ultimately turn into a sugar complex in the body as it is being broken down.
Also, the muffin lacks in protein, which is essential to weight loss!
