[sidebar]I have a better proposal

Before your vacation, aim to lose 5 to 6 pounds, a more realistic amount that won’t require draconian measures. In the meantime, buy a new pair of jeans (you’ll look thinner in clothes that fit right). Don’t deprive yourself while you’re away, but don’t go overboard on the piña coladas and crème brûlées, either. Then, after you return from your vacation, continue your weight loss efforts, and by midsummer you should be back in those white jeans.  To lose about 5 1/2 pounds safely: 

Limit your food intake to 1,500 calories daily. Burn off 300 calories a day, 6 days a week, with aerobic exercise, such as walking. Lift weights 3 days a week, focusing on your arms, shoulders, and upper back.

The aerobic exercise and calorie cutting will shed pounds, and the weight lifting will give you firm, shapely muscles. Show them off with sleeveless or low-back outfits, and no one will notice the few extra pounds you’re still carrying around. Here are some proven ways to maximize weight loss that have helped me slim down before filming Prevention’s exercise videos.[pagebreak]

Keep a food diary

Research suggests that weight loss is more likely if you monitor what and how much you eat by writing it down.

Replace carbs with protein

In the short term, low-carb diets (high in protein-rich foods such as eggs, chicken, and fish) tend to cause more rapid weight loss than low-fat diets (often high in carb-rich pasta and cereal) by suppressing appetite.

Pick up the pace

Adding 1- to 2-minute bursts of high-intensity activity to whatever exercise you do cranks up calorie burn during and after your workout. Aim for five or six bursts per session.

Get automatic portion control

Reduced-calorie frozen meals such as Healthy Choice and Lean Cuisine make calorie counting easy.

Turn in early

Studies show that a lack of sleep alters hormone levels that can make you hungrier and shift your body into fat-storage mode, making weight loss more difficult. To help the scale numbers move in the right direction, get at least 7 hours of shut-eye a night.

Skip a meal

Not literally, but instead of your typical lunch, try a meal replacement bar. Dozens of studies have shown that liquid meal replacements help people with weight loss; a new study suggests that bars, which can offer similar benefits, satisfy your hunger for 2 hours longer than shakes.  And when you’re tempted to indulge, remind yourself that it’s only for a few weeks, and you can enjoy some treats while you’re on vacation.
