The timing and duration of spring turnover depends on the size and depth of the lake. As the weather becomes warmer in late May, the surface water warms again and begins to float on top of the cold deeper water. Once the lake begins to form into layers, summer stratification (layering) has begun. You can track spring turnover in an individual lake with a Secchi disk. A Secchi disk measures water clarity. During spring turnover, the clarity of a lake usually decreases because mixing brings up nutrient rich water from the bottom of the lake and causes the lake to look cloudy.
The weight appears to come back so quickly because when you are at your lightest, you tend to gain more weight each day. The lighter you are, the fewer calories you need. If you only need 1,500 calories per day and you're eating 2,000, you're going to gain weight faster than if you need 1,800 and you're eating 2,000.
When you lose weight, where does the lost body fat go? Answers from Edward R. Laskowski, M.D. To understand the answer, it helps to remember that fat is basically stored energy. Your body converts fat to usable energy for your muscles and other tissues through a series of complex metabolic processes. This causes your fat cells to shrink. These metabolic activities also generate heat, which helps maintain your body temperature, and waste products. These waste products â water and carbon dioxide â are excreted in your urine and sweat or exhaled from your lungs.
