Avoid extremely rapid weight loss (e.g., 100 lb in 12 weeks via 4-5 hr/day exercise) because it doesn't teach sustainable habits and leads to lean mass loss and metabolic adaptation.

Limit saturated fat intake; substituting polyunsaturated fat for saturated fat lowers LDL and reduces cardiovascular disease risk on balance.
