No... Lactose (the sugar that's in milk) is different from regular sugars (such as in a candy bar). It's not unhealthy, at all.

New Study Strengthens Milk's Fat Burning Link
Most people know that to lose weight, they'll need to eat less and move more. However, new research suggests you may have better luck if you include milk in your new routine.
Published in the December issue of Obesity Research by scientists at the University of Colorado, the new study provides more insight into why consuming dairy foods is linked with weight and fat loss. This well-controlled study found that when adults on a reduced-calorie diet exercised and consumed 3 to 4 servings of dairy foods daily, their metabolism changed so their bodies burned more fat compared to adults only consuming one serving of dairy under the same conditions.
Researchers measured fat oxidation (or the amount of fat burned) using a metabolic chamber, an enclosed living area that allows for precise scientific measurements. They found that the adults with higher intakes of dietary calcium burned significantly more fat than those who consumed a low-dairy diet.
The scientists suggest the reason for the increased fat burning may be related to certain hormones in the body that regulate fat breakdown and oxidation. The calcium in dairy foods appears to suppress these hormones.
This research shows how reducing calories, exercising and consuming adequate amounts of dairy foods can help improve the body's ability to burn fat.

14-Aug-2007 - Drinking fat-free milk after resistance exercise has a greater effect on helping to increase lean body mass compared to soy or carbohydrates in young male weightlifters, a study has concluded.
Researchers from McMaster University, Canada, found taking milk after a work-out promotes a greater protein balance than consuming a soy protein drink.
The work, published in the American Journal of Clinical Nutrition, adds to an increasing body of evidence to the positive health benefits of milk in the sports nutrition market, which is currently dominated by isotonic drinks.
Earlier this month researchers from the UK's Loughborough University's School of Sports and Exercise Sciences found that drinking skimmed milk after exercise may promote recovery and rehydration better than water or an isotonic sports drink.
Their work, published in the British Journal of Nutrition, found a group of volunteers remained hydrated after drinking milk, but remained dehydrated after drinking the other drinks.
According to market analyst Mintel, the sports drink market in the UK was worth ?137m ($252m, ?200m) in 2003, and is dominated by isotonic drinks like Lucozade Sport, Powerade and Gatorade.
In the US, the sports drinks market is reported to have generated almost $3** (?1.6**, ?2.4**) with Gatorade dominating the market with 82 per cent of the market. Powerade is a distant second with a reported 13 per cent of the market.
In the past five years there have been 128 launches of milk based sports drinks launched globally, according to Mintel's Global New Product Database.
This study aimed to determine the long-term consequences of milk or soy protein or equivalent energy consumption on training-induced lean mass accretion.
Fifty-six healthy young men were recruited, split into three groups, and asked to train five days a week for 12 weeks on a rotating split-body resistance exercise program.
They were then randomly assigned to consume drinks immediately and again after one hour exercise. The groups were given fat-free milk, fat-free soy protein that was isoenergetic, isonitrogenous, and with macronutrient ratio matched to milk. The third group had maltodextrin that was isoenergetic with milk and soy.
Muscle fibre size, maximal strength, and body composition by dual-energy X-ray absorptiometry (DXA) were measured before and after training. The researchers found that no between-group differences were seen in strength and that type II muscle fibre area increased in all groups with training, but with greater increases in the milk group than in both the soy and control groups.
Type I muscle fibre area increased after training only in the milk and soy groups, with the increase in the milk group being greater than that in the control group. DXA-measured fat- and bone-free mass increased in all groups, with a greater increase in the milk group than in both the soy and control groups.

The researchers concluded that chronic postexercise consumption of milk promotes greater hypertrophy during the early stages of resistance training in novice weightlifters when compared with isoenergetic soy or carbohydrate consumption.

i drink maybe a little bit less than half since money is starting to be an issue and i only go to the grocery store when i go to work which is weekends so i cant buy like 3 gals because i have no space in the fridge for it. an dplus its like 5$ a gal now :[
